Nanosatellite thruster emits pure ions – MIT News

§ January 24th, 2021 § Filed under Nanotechnology Journal Comments Off on Nanosatellite thruster emits pure ions – MIT News

A 3D-printed thruster that emits a stream of pure ions could be a low-cost, extremely efficient propulsion source for miniature satellites.

The nanosatellite thruster created by MIT researchers is the first of its kind to be entirely additively manufactured, using a combination of 3D printing and hydrothermal growth of zinc oxide nanowires. It is also the first thruster of this type to produce pure ions from the ionic liquids used to generate propulsion.

The pure ions make the thruster more efficient than similar state-of-the-art devices, giving it more thrust per unit flow of propellant, says Luis Fernando Velsquez-Garca, principal research scientist at MITs Microsystems Technology Laboratories (MTL).

The thrust provided by the device, which is about the size of a dime, is minuscule. The force can be measured on the scale of a few tens of micronewtons, a thrust about equal to half the weight of one of the sesame seeds in a hamburger bun. But in the frictionless environment of orbit, a CubeSat or similarly small satellite could use these tiny thrusts to accelerate or maneuver with fine control.

Velsquez-Garca says additive manufacturings advantages offer new low-cost possibilities for powering satellites. If you want to be serious about developing high-performance hardware for space, you really need to look into optimizing the shapes, the materials, everything that composes these systems. 3D printing can help with all of these things, he says.

Velsquez-Garca and MTL postdoc Dulce Viridiana Melo Mximo describe the thruster in the December 2020 issue of the journal Additive Manufacturing. The work was sponsored by the MITTecnolgico de Monterrey Program in Nanoscience and Nanotechnology and the MIT Portugal program.

Electrospraying pure ions

The miniaturized thruster operates electrohydrodynamically, producing a fine spray of accelerated, charged particles that are emitted to produce a propulsive force. The particles come from a sort of liquid salt called ionic liquid.

In the MIT design, a 3D-printed body holds a reservoir of ionic liquid along with a miniature forest of emitter cones coated with zinc oxide nanowires hydrothermally grown on the cone surfaces. The nanowires act as wicks to transport the liquid from the reservoir to the emitter tips. By applying a voltage between the emitters and a 3D-printed extractor electrode, charged particles are ejected from the emitter tips. The researchers experimented with printing the emitters in a type of stainless steel as well as a polymer resin.

The researchers were able to detect the pure ion jet using a technique called mass spectrometry, which can identify the composition of particles based on their molecular mass. Typically, an electrospray produced from ionic liquids would contain ions plus other species made of ions mixed with neutral molecules.

The pure ion jet was a surprise, and the research team still isnt entirely sure how it was produced, although Velsquez-Garca and his colleagues think the zinc oxide nanowires are the secret sauce, he says. We believe it has something to do with the way the charge is injected and the way the fluid interacts with the wire material as it transports the fluid to the emission sites.

Producing a jet of pure ions means that the thruster can utilize more efficiently the propellant on board, and propellant efficiency is key for objects in orbit because refueling satellites is rarely an option, he explains. The hardware that you put into space, you want to get many, many years of use out of that, so I think its a good strategy to do it efficiently.

Advantages of additive manufacturing

Electrospray designs can have many applications beyond space, says Velsquez-Garca. The technique can emit not just ions, but also things like nanofibers and droplets. You could use the fibers to make filters, or electrodes for energy storage, or use the droplets to purify seawater by removing brine. You could also use electrospray designs in a combustor, to atomize fuel into very small and fine droplets.

The nanosatellite thruster is a good example how additive manufacturing can produce devices that are personalized, customized and made from finely featured, complex multi-material structures, he adds. Instead of using expensive laser machining or clean-room technologies for specialized industrial manufacturing, he and his colleagues made the thruster mostly on commercial printers using instructions that can be distributed widely.

And since the techniques are relatively inexpensive, fast, and easy to use, Velsquez-Garca says designs can be exquisitely iterated to improve features and explore surprising effects, such as the pure ion emission in the case of the new thruster.

The advantages of 3D printing microsystems include lower costs and shorter times for prototyping and development, along with the ease of assembling multimaterial structures, says Tomasz Grzebyk, a microsystems professor at Wroclaw University of Science and Technology, who was not involved with the study.

All these advantages can be seen also in the ion thrusters developed at MIT, Grzebyk says. And what more, since there has been a great progress in 3D printing in last few years, the parameters of devices fabricated using this method are becoming similar to these obtained by much more complex, expensive and restricted to specialized laboratories microengineering techniques.

3D printing technology is also constantly improving, potentially making it possible to implement in the near future even better systems that have smaller features and are made of better materials, he says. We are on track to producing the best possible hardware that a lot more people can afford.

Nano-hinges are the next step in development of molecular machines – Innovation Origins

§ December 31st, 2020 § Filed under Nanotechnology Journal Comments Off on Nano-hinges are the next step in development of molecular machines – Innovation Origins

Scientists from Finland and Israel have found a way to enable nano-scaled hinges to move. This marks the next step in the development of what are known as molecular machines. This will ultimately make it possible to develop new therapeutic approaches in e.g. medicine.

Until now it has not been possible to control these kinds of nanomachines. The team of researchers from Aalto University in Finland and the Weizmann Institute in Israel have succeeded in creating a structure that opens and closes like a hinge on command. Its a bit like origami, that Japanese art of folding, according to the researchers.

In order to be able to build such a hinge, the scientists opted for the use of DNA. DNA not only carries genetic codes, but can also take on many different forms: the nano-hinges are contained in a solution that becomes more acidic when light shines on it. The increasing acidity of the solution causes chemical bonds to form in the ends of the hinges thereby closing the hinges, says Finnish scientist Joonas Ryssy. When the light is turned off, the acidity of the solution is reversed, causing the bonds between the ends to break and the hinges to open again. Only one light source is needed for that switching.

The results were published in the professional journal Angewandte Chemie. The research is a follow-up of earlier studies by the same group on the manipulation of macromolecules. The use of light to control the hinge is an attractive option because it can be done remotely.

Anton Kuzyk, professor at Aalto University: If we dont want all the hinges to close, we reduce the amount of light. This level of control is an exciting feature of our system that sets it apart from others.

Bayly named inaugural Lee Hunter Distinguished Professor – Washington University in St. Louis Newsroom

§ December 20th, 2020 § Filed under Nanotechnology Journal Comments Off on Bayly named inaugural Lee Hunter Distinguished Professor – Washington University in St. Louis Newsroom

Philip V. Bayly, an innovative researcher of waves and oscillations in the mechanics of cells and biological tissues, has been named the inaugural Lee Hunter Distinguished Professor in the McKelvey School of Engineering at Washington University in St. Louis.

Bayly, who has been chair of the Department of Mechanical Engineering & Materials Science since 2008, was installed Oct. 28.

It is fitting that Phil Bayly will be taking on the Hunter professorship. Like Lee Hunter, Professor Baylys work showcases the importance of creativity in engineering, Chancellor Andrew D. Martin said. This creativity will certainly revolutionize the way society understands and treats head trauma.

Lee Hunters work revolutionized the automotive industry, and his legacy persists, thanks to his stepson, Stephen Brauer, Martin said. We are grateful for the Brauers continued, generous support of Washington University in St. Louis and honored to help keep Mr. Hunters legacy alive with the Lee Hunter Distinguished Professorship.

Phil Bayly is not only an exceptional engineering researcher who is looking at the mechanics behind traumatic brain injury as well as other areas of mechanobiology, but hes also an outstanding engineer, as well as leader and teacher, said Aaron F. Bobick, the James M. McKelvey Professor and dean of the McKelvey School of Engineering.

While Phil will tell you that his best days are the ones he gets to work in his lab with his students on their research, his engineering leadership is always present. When the COVID-19 pandemic created a potential for a shortage of ventilators, he organized a team of mechanical and electrical engineers to create emergency ventilators that could be locally manufactured and immediately deployed. We are grateful to the Brauer family for continuing to support outstanding faculty such as Phil Bayly as a way to honor Lee Hunter and his legacy, Bobick said.

Since Bayly has been chair of the department, undergraduate and PhD student enrollment have each increased by 30%, while masters degree enrollment has increased by 374%. Faculty research expenditures are up 237%; and department faculty increased from 10 tenured/tenure-track faculty and one teaching faculty member in 2008 to 17 tenured/tenure-track faculty, seven teaching faculty members and two professors of the practice as of Oct. 2020.

In addition, Bayly provided guidance on the interior spaces of Henry A. and Elvira H. Jubel Hall, which became the departments home in summer 2019. The building, which contains classrooms, laboratories, faculty offices, study areas and the Spartan Light Metal Products Maker Space, allows mechanical engineers to work closely with physicists, chemists, biologists, and chemical and biomedical engineers to promote the convergence of mechanics, materials science and nanotechnology.

Baylys research focuses on impact, vibration, wave motion and instability in mechanical and biomedical systems. He uses magnetic resonance imaging (MRI) to investigate the mechanics of brain injury and brain development. Recently, he and members of his lab have been collecting data on how the brain moves in response to slight vibrations, in order to build mathematical simulations of head trauma. His research has been funded by the National Science Foundation (NSF), the Whitaker Foundation and the National Institutes of Health (NIH).

Bayly joined the Washington University faculty in 1993. In 1996, he received the prestigious Faculty Early Career Development (CAREER) award from the NSF. In 2004, he was awarded Engineering Professor of the Year, and he has twice received the McKelvey Schools Big Fish Award for graduate student mentoring. He received the Richard Skalak Award for Best Paper from the Journal of Biomechanical Engineering in 2013 and 2018. In recognition of his commitment to the intellectual and personal development of Washington University students, Bayly received the Founders Day Distinguished Faculty Award in 2014.

Bayly earned a bachelors degree in engineering science from Dartmouth College, a masters in engineering from Brown University and a doctorate in mechanical engineering from Duke University. Before pursuing a doctorate, he worked as a research engineer for the Shriners Hospitals and as a design engineer for Pitney Bowes.

The Lee Hunter Distinguished Professorship was established in 2017 by Stephen F. and Camilla T. Brauer, longtime supporters of Washington University and the McKelvey School of Engineering, during the Leading Together campaign.

Lee Hunter founded Hunter Engineering in 1946. Prior to beginning his business career, Hunter studied at Westminster College and Washington University and served in World War II as a lieutenant of engineers for the U.S. Army. Hunter invented numerous products that revolutionized the automotive service industry worldwide.

His inventions included the Kwikurent, a device that could rapidly charge a car battery, the Lite-A-Line wheel alignment system and the Tune-In on-car balancer. In 1992, Hunter was posthumously inducted into the Automotive Hall of Fame. He served on the Washington University Engineering School Task Force beginning in 1979 and then the schools National Council in the 1980s. He was a member of the universitys Board of Trustees from 1982-86. In 1983, he established the Lee Hunter Professorship in Mechanical Design, currently held by mechanical engineering professor Mark Jakiela.

Today, Stephen Brauer serves as chairman of Hunter Engineering. In this role, he continues to lead in the style of Lee Hunter driving excellence by investing in people and innovation. The company is a global leader in the automotive products service industry.

The Brauer family is dedicated to advancing the mission of Washington University. Stephen Brauer is a member of the Board of Trustees and the McKelvey Engineering National Council. Camilla Brauer serves on the Eliot Society Danforth Circle Committee. In 1996, she was recognized as the Outstanding Fundraising Volunteer in the United States by the National Society of Fundraising Executives. Together, the Brauers have been honored by the university with the Jane and Whitney Harris St. Louis Community Service Award, the Eliot Society Search Award and the Robert S. Brookings Award.

Among their many generous gifts, the couple endowed the Stephen F. and Camilla T. Brauer Distinguished Professorship in Biomedical Engineering and provided the lead gift for the construction of Stephen F. and Camilla T. Brauer Hall.

IIT Guwahati Researchers Develop Efficient Method To Harvest Drinking Water From Air

Image credit: IIT Guwahati

Researchers at Indian Institute of Technology Guwahati have developed novel materials that can efficiently harvest water from humid air. A team of researchers led by Dr Uttam Manna, Associate Professor, Chemistry Department and Centre of Nanotechnology, IIT Guwahati, has published the results of their work in the journal of The Royal Society of Chemistry.

The other research scholars in the team are Mr Kousik Maji, Mr Avijit Das, and Ms Manideepa Dhar.

IIT Guwahati said in a statement that scientists around the world are trying to collect and conserve water through non-traditional methods.

In regions of the world with naturally scanty rainfall, plants and insects have devised ingenious strategies to pull and collect water out of the air. Mimicking this, scientists worldwide are trying to build technologies that can pull out water from thin air.

Such water-harvesting techniques use the concept of hydrophobicity or water-repelling nature of some materials, lead researcher Dr Manna said.

Leaves of plants like lotus are water repellent in nature due to the presence of a layer of trapped air between the leaf surface and the water droplet, which causes the droplet to slide off the leaf.

However simple hydrophobicity such as this is unsuitable for water harvesting from highly humid environments because high moisture content can displace the trapped air and cause permanent damage, an official statement said.

IIT Guwahati researchers have mimicked the pitcher plant -- an insect eating plant with a slippery surface.

The research team from IIT Guwahati has used the concept of chemically patterned SLIPS (Slippery Liquid-Infused Porous Surfaces) to effectively harvest water from moist air.

The researchers produced a patterned hydrophilic SLIP by spraying a sponge-like porous polymeric material on top of a simple A4 printer paper.

Further, chemically modulated hydrophilic spots were associated on the coating prior to lubricating with two distinct types of oils natural olive oil and synthetic krytox.

We have produced a highly efficient water harvesting interface where the fog collecting rate is as high as 4400190 mg/cm2/h, Dr Uttam Manna said.

IIT Guwahati said that their pitcher-plant inspired SLIPS materials are superior to other bio-inspired ideas in terms of efficiency of water harvesting.

Apart from water harvesting, SLIPS could be used for other purposes, such as easily cleanable household appliances, in underwater hulls of ships and submarines to prevent biofouling and anti-icing windows for aircraft.

New life sciences innovation centre given go-ahead at University of the Highlands and Islands campus – RossShire Journal

§ December 1st, 2020 § Filed under Nanotechnology Journal Comments Off on New life sciences innovation centre given go-ahead at University of the Highlands and Islands campus – RossShire Journal

Proposed innovation centre for Inverness Campus

A new life sciences innovation centre will be built in the Highlands after being granted planning permission.

The 2500m facility at Inverness Campus is a joint project between Highlands and Islands Enterprise (HIE) and the University of the Highlands and Islands (UHI).

Designed by multi-disciplinary design firm Austin-Smith:Lord, the centre will form part of a wider project with NHS Highland.

The health authority is developing an elective care facility at the site and, together, these are forecast to create around 190 jobs.

Ruaraidh MacNeil, HIEs director of business infrastructure, said: This is a major development for Inverness and for the Highlands and Islands.

The life sciences innovation centre will generate new commercial opportunities including new business start-ups, attracting new companies to the area, creating high value career opportunities.

It will also support the continued growth of the University of the Highlands and Islands through new research and other development opportunities.

The nearby NHS Highland facility, meanwhile, will improve the health outcomes and patient experience across the Highlands and Islands. All of this will help attract and retain new talent for the region.

Fiona Larg, chief operating officer and secretary at the University of the Highlands and Islands, said: We are delighted that planning consent has been granted for this collaborative venture.

The development will increase our research in fields such as medical nanotechnology and active health and will help us to provide greater support to the regions life sciences sector.

We hope to create a facility of national significance which will bring economic benefits to our region through innovation, commercialisation, company and job creation and the attraction and retention of talent.

Procurement of a contractor to build the new centre is expected to get underway in early December.

The University of the Highlands and Islands life sciences programme, including its element of the life sciences innovation centre, secured 9m from the UK Government through the Inverness and Highland City-Region Deal.

The Deal is a joint 315 million initiative supported by both the UK and Scottish governments.

The new facility also benefits from 3.75 million of part-funding by the European Regional Development Fund European Structural Funds Programme 2014-2020.

Scotland Office Minister Iain Stewart said: This is a major step forward for such an important project.

Backed by 9 million of UK Government funding, the University of the Highlands and Islands life sciences programme, including the life sciences innovation centre, will put the area right at the heart of this crucial sector.

It is pleasing to see progress being made on the 315 million Inverness and Highland City-Region Deal.

The UK Government has now committed more than 1.5 billion to city-region and growth deals across every part of Scotland.

TipRanks

Expectations of good news on the near horizon are buoying markets right now. Over the past month, both the S&P 500 and the NASDAQ are up 11% to new record highs.Investors are excited at the prospect of a COVID vaccine coming before the winter is out. And the electoral results, that Democrat Joe Biden will ascend to the Presidency while the Republicans will emerge strengthened in Congress, promise the avoidance of extremes typical of divided government. In short, investors are looking forward to return to normal environment over the next several months. And that has them seeking stocks that are primed for gains. Against this backdrop, Goldman Sachs analysts are pounding the table on three stocks in particular, noting that each could surge over 40% in the year ahead. After running both tickers through TipRanks database, we found out that the rest of the Street is also standing squarely in the bull camp.Codiack BioSciences (CDAK)As we have all learned from coronavirus pandemic, some new thing in medical science can make huge impact on our world. Codiack aims to turn that principle to good. This research-oriented pharmaceutical aims to turn exosome therapeutics into a whole new class of medicines. Exosomes are the degradation mechanism RNA, and can transfer genetic material around a body.And therein lies the potential. Codiack has developed a design platform for the engineering of exosome proteins capable of carrying and protecting drug molecules through cell walls. In effect, the proteins will mimic the pathways used by viruses but are non-viral, and are designed to carry a payload of therapeutic agents. If successful, exosome therapy offers doctors the ability to design a drug that will deliver specific agents to specific cells to fight specific disease.Codiack is involved in all aspects of exosome therapeutics, from design to manufacturing, and currently has an active pipeline of agents seven, in all in various stages of discovery, preclinical testing, and the beginnings of Phase 1 trials.In the biosciences, success or failure is all about that pipeline, and in its diverse, active pipeline of agents in a new sector of biotechnological pharmaceuticals, Codiack has a fine resource to attract investors. To get those investors, the company went public this past October, selling 5.5 million shares at an opening price of $14.10 per share.Among the healthcare name's fans is Goldman Sachs analyst Graig Suvannavejh. The analyst wrote, Biopharma industry interest in exosomes has long been high, but engineering them for a specific function and manufacturing at scale have both proven challenging. Among a field of multiple competitors, CDAK has made the most significant progress on both fronts, and as such we view their technology platform as best-in-class."Given share underperformance (-37%) since the IPO, we find risk/reward highly compelling at current levels, and with key 2021 data sets to provide potential de-risking and positive share inflection," the analyst concluded.Suvannavejh rates CDAK a Buy, and his $29 price target shows the extent of his confidence it implies a 222% upside for the coming year. (To watch Suvannavejhs track record, click here)Overall, Codiack has a Strong Buy from the analyst consensus 3 reviewers have put up Buy ratings in recent weeks. The stock is selling for $8.90, and its $24 average price target implies a 166% one-year upside potential. (See CDAK stock analysis on TipRanks)Arcutis Biotherapeutics (ARQT)Acrutis is a pioneering researcher in the treatment of dermatological disease. Arcutis is involved in discovering the next generation of dermatological treatments an important niche, especially when one realizes that one common ailment, psoriasis, has not seen an FDA approval for a novel treatment in over two decades.The company is leveraging recent advances in immunology and inflammation to find new approaches to skin treatment. The goal is to make it easier for patients and doctors together to manage conditions like psoriasis, alopecia, atopic dermatitis, seborrheic dermatitis, and vitiligo, to name just a few.The company's lead candidate, ARQ-151 (roflumilast cream), is about to enter a phase 3 trial for atopic dermatitis, and is in an advanced phase 3 stage in Plaque Psoriasis. Arcutis has recently issued an update on positive data from the Phase 2 trials of ARQ-151 in atopic dermatitis. The drug is a once-daily treatment, and has demonstrated significant patient relief from symptoms, especially itching and itching-related sleep problems. This is another stock in Suvannavejhs coverage universe. The Goldman analyst is impressed by developments in the companys pipeline work, noting: ARQT provided an update on the outcome of its end-of-Phase 2 meetings with the FDA, following their Phase 2a trial of ARQ-151 in atopic dermatitis (AtD). Feedback from regulators was broadly encouraging, in particular, acknowledging the robust long-term safety data being generated by ARQT for ARQ-151 in plaque psoriasisAccordingly, Suvannavejh rates ARQT a Buy, and sets a $36 price target that indicates room for 40% upside growth in 2021. (To watch Suvannavejhs track record, click here)Arcutis has 2 recent Buy reviews, making the consensus rating a Moderate Buy. The stocks average price target is $37, suggesting a 44% upside from current levels. (See ARQT stock analysis on TipRanks)Oak Street Health (OSH)With the last stock, we move from medical research to medical care. Specifically, Oak Street Health is a primary care clinic operator, and part of the Medicare Network. The company has operations and clinics in Illinois, Indiana, Michigan, Pennsylvania, and Ohio, along with New York, North Carolina, Rhode Island, Tennessee, and Texas. It has been in operation for eight years, and went public this past summer, holding the IPO in August.In the third quarter, the companys first as a publicly traded entity, OSH brought in $217.9 million in revenue. The revenue number was up 56% from the year-ago quarter. Earnings per share matched expectations, at 15 cents.The companys expansion proceeds apace, and in October, Oak Street entered New York by opening, in Brooklyn, its 70th location. A planned expansion in Texas, involving a partnership with Walmart, is also proceeding as planned, and Oak Street has opened its first Walmart Community Clinic the Dallas-Fort Worth area city of Carrollton.Robert Jones, covering this stock for Goldman, set a $74 price target to back his Buy rating. At currently levels, this target implies an upside of ~58% in the next 12 months. (To watch Jones track record, click here)Results suggest operations are still on track, with few incremental updates since the 2Q call, where management noted a resumption of center openings, (pivoted) marketing efforts, and in-person visits despite COVID. In 3Q, OSH opened 13 new centers and is on track for 73-75 by end of year The company maintained that it is continuing to operate at a high level in places with elevated COVID case counts like Chicago and Detroit, Jones noted.All in all, the Strong Buy analyst consensus rating OSH is based on 8 reviews, breaking down to 7 Buys and just a single Hold. The stock is selling for $46.94, and its $61.29 average price target suggests it has a ~31% upside for the coming year.

The Canadian connection to a promising COVID-19 vaccine – Nipawin Journal

§ November 12th, 2020 § Filed under Nanotechnology Journal Comments Off on The Canadian connection to a promising COVID-19 vaccine – Nipawin Journal

A small Canadian biotech company is playing a starring role in a COVID-19 vaccine whose positive early results made headlines this week.

On Sunday, pharmaceutical giant Pfizer and German company BioNTech announced that their RNA-based COVID-19 vaccine is more than 90 per cent effective, according to early data.

There are still many questions that need to be answered about the vaccine, which is one of dozens in development around the world.

But it has put Vancouver-based Acuitas Therapeutics, which developed the nanotechnology that enables the Pfizer vaccine to work, in the spotlight. Its contribution is the delivery system based on lipid nanoparticles that allows the messenger RNA to be safely delivered to its target.

President and CEO Thomas Madden, a world expert in the field of nanotechnology, said he and others at the company have been on tenterhooks waiting to see data from the clinical trials of the vaccine.

Everybody is just delighted that it is looking so positive.

Canadian scientist Alan Bernstein, who is president and CEO of the global research organization CIFAR and a member of Canadas COVID-19 vaccine task force, likens lipid nanoparticles to small soap bubbles that protect the messenger RNA from degrading, facilitate getting it into cells, and enable it to act like a booster to the immune system.

Without lipid nanoparticles, there would be no RNA vaccines.

Madden has, in interviews, compared the delivery technology to a carrier for a fragile glass ornament getting delivered to your home. Not only would the carrier protect the ornament, it would let itself into the home, unwrap the package and leave the ornament, he said.

Vaccines that are based on messenger RNA are relatively new. The technology will get high-profile tests in the fight against COVID-19. Pfizer is not the only company whose experimental vaccine is based on the technology.

Moderna, which is also expected to report trial results soon, has also developed a RNA vaccine, as have others, including at least one Canadian vaccine.

Like other vaccines, those designed using messenger RNA trigger the body to produce an immune response, in this case to COVID-19. They do it by introducing a mRNA sequence (telling the cells what to build) that produces an antigen that triggers an immune response.

The vaccines are generally faster and cheaper to produce than traditional vaccines, however RNA is fragile and needs to be protected. That is where nanotechnology comes in.

Madden said the carrier system technology was originally created with the hope that it could be used in gene editing. Over years, the technology, developed by a researcher at the University of British Columbia, has been improved and is now used for vaccines and therapeutics.

It is definitely Canadian and Canadians should take pride in the fact that they are contributing, said Madden.

Everyone at the small company which employs 29 people has been working since February to support efforts around the COVID-19 vaccine.

We are trying to compress many years of development work into a few short months, he said.

Madden said contributing to the vaccine effort has been rewarding.

Everybody has been impacted by COVID-19 to a lesser or a greater extent. What has been fantastic for my colleagues is that they have the feeling they are contributing toward the solution. The work is intended to help us emerge from this pandemic.

Bernstein said the lipid nanotechnology is one of the strong Canadian connections to research aimed at ending the pandemic.

The lesson here is about science and global collaboration.

Sliding on Waves of Atoms: Lab Is First to Observe Ripples and Friction on 2D Materials | Newsroom – UC Merced University News

§ November 6th, 2020 § Filed under Nanotechnology Journal Comments Off on Sliding on Waves of Atoms: Lab Is First to Observe Ripples and Friction on 2D Materials | Newsroom – UC Merced University News

By Lorena Anderson, UC Merced

Professor Mehmet Baykara and his colleagues have been able to prove the existence of frictional ripples.

Mechanical Engineering Professor Mehmet Baykaras latest discovery in two-dimensional (2D) materials will have implications for future space missions, as well as nanotechnology on Earth.

Since the Nobel prize-winning discovery of 2D materials in 2004, scientists have believed the crystalline materials consisting of a single layer of atoms intrinsically have ripples that dictate their frictional properties on nanometer-length scales. While such ripples were observed using methods such as electron microscopy, they were never seen during friction experiments, making it hard for scientists to form connections between the presence of ripples and the peculiar frictional properties they exhibit.

Now, Baykara and his nanoscience lab at UC Merced, together with collaborators at McGill University in Canada, have for the first time detected the presence of these ripples on the 2D material molybdenum disulfide (MoS2) using atomic force microscopy the main tool scientists use to study friction on the nanoscale.

Their discovery allows concrete connections to be made between the presence of the ripples and the frictional characteristics exhibited by MoS2, especially its direction dependence.

MoS2 is a particularly important material used as a solid lubricant necessary for nanomachines and for space missions.

Space is extremely cold, and you are under vacuum: Liquid lubricants that we use in conventional machinery would simply freeze up or evaporate, Baykara explained. On the other hand, in very small, nanoscale machines, conventional lubricants just ball up. For such applications, what you really need are solid lubricants like MoS2.

An image of frictional ripples

Understanding the frictional properties of 2D materials such as MoS2 in depth will help in designing equipment that employs solid lubricants.

Now that we can see the presence of these ripples and measure their properties, we have a critical piece of information that will help us figure out in what fashion we need to use solid lubricants in nanomachines for optimal performance, Baykara said.

A recent paper in the journal npj 2D Materials and Applications details the results of Baykara and his collaborators work. The research was supported by the Merced nAnomaterials Center for Energy and Sensing (MACES), which has several affiliates working on projects for NASA. Baykara is also affiliated with the Health Sciences Research Institute.

While trying to actively control the distribution and the direction of ripples could be a potential area of future research, Baykara said his lab will primarily extend their work to more recently discovered members of the 2D materials family.

Friction is a fascinating phenomenon and we, as a community of scientists and engineers, are still trying to understand its basic physical principles, Baykara said. 2D materials, thanks to their extraordinary properties, provide an excellent platform to search for the fundamentals of friction.

Faster way of detecting antibiotic resistance developed by researchers – University of Sheffield News

§ November 6th, 2020 § Filed under Nanotechnology Journal Comments Off on Faster way of detecting antibiotic resistance developed by researchers – University of Sheffield News

3 November 2020

A new, quicker way of detecting antibiotic resistance in bacteria has been developed by a team of scientists from the EPSRC funded interdisciplinary research collaboration, i-sense.

The new technique, developed by a collaborative team of researchers including a scientist from the University of Sheffield, uses nanotechnology to detect antibiotic resistance in approximately 45 minutes.

The standard method for detecting resistance is a relatively slow process that typically takes between 12 and 24 hours. The ability to reduce this time could significantly help the ongoing battle against antibiotic-resistant bacteria - a problem which is predicted to cause 10 million deaths per year and cost the global economy $100 trillion by 2050.

Speeding up the time it takes to identify antibiotic-resistant bacteria could improve our ability to prescribe antibiotics correctly and reduce the misuse of antibiotic treatments - a key step in the fight against antibiotic resistance.

The new method developed by Dr Isabel Bennett from UCL in collaboration with Dr Alice Pyne from the University of Sheffields Department of Materials Science and Engineering and Professor Rachel McKendry from UCL uses a new Atomic Force Microscopy (AFM) detection system.

This method uses a nanomechanical cantilever sensor together with a laser to detect single bacterial cells as they pass through the lasers focus, which provides a simple readout of antibiotic resistance by detecting growth (resistant) or death (sensitive) of the bacteria.

By placing a reflective surface - a small stiff cantilever - in a filtered growth medium in a petri dish and reflecting a laser off it onto a photodiode detector, it is possible to detect bacteria as they pass through the path of the laser, therefore altering the signal at the detector. Following the addition of the antibiotic to the petri dish, the study has shown that it is possible to detect whether fewer bacteria interfere with the laser beam, thereby indicating cell death in the antibiotic-sensitive bacteria.

The new technique developed by Dr Bennett builds on an AFM method from a previous study, however Dr Bennetts method doesnt require the bacteria to be immobilised - making the new detection system much faster.

Dr Bennett said: Our method allowed us to quickly differentiate between resistant and sensitive phenotypes in multiple strains of E. coli, a bacteria implicated in a number of challenging infections including UTIs.

Dr Alice Pyne from the University of Sheffield added: We were able to show that our faster method was able to reproduce values from gold standard measurements, such as MICs in a fraction of the time.

The study, Cantilever Sensors for Rapid Optical Antimicrobial Sensitivity Testing, was conducted by Dr Isabel Bennett as part of her PhD supervised by Dr Alice Pyne and Professor Rachel McKendry.

The research by the all-female team of scientists is published in the journal ACS Sensors. The journal has published an interview with Dr Bennett following the paper being selected as an ACS editors choice. The interview can be accessed via: https://pubs.acs.org/doi/10.1021/acssensors.0c02086

On the Defense Against COVID-19 – UT News | The University of Texas at Austin

§ November 5th, 2020 § Filed under Nanotechnology Journal Comments Off on On the Defense Against COVID-19 – UT News | The University of Texas at Austin

Mbolle Ekane and her research material. (Credit: Mbolle Ekane)

Mbolle Ekane is one of these students. She is a cell and molecular biology senior who has been working with Ellington since 2017. Ekane described how the lab is focusing on the many unexplored approaches to mitigating COVID-19. Her project in particular explores the overreaction of the immune system to the virus.

Basically, when you first get infected, your immune systems like, Hey, lets go fight this, Ekane explained.

This immune response can be positive, but with COVID-19 it can also cause complications called a cytokine storm. This occurs when the bodys immune response goes into overdrive and starts to attack its own cells and tissues, and not just the virus.

What it does is release these cytokines to try and fight the virus. However, the virus essentially takes over that mechanism, and it becomes a negative feedback loop where youre overexpressing those cytokines your body ends up damaging more cells than youre actually helping, Ekane said.

Whats most significant about cytokine storms is their correlation with patient deaths from COVID-19. Studies from Signal Transduction and Targeted Therapy and Frontiers in Immunology show that decreasing this over-response is beneficial for patients, and Ekanes work supports the idea that breaking down this response with some sort of therapeutic could aid COVID-19 patients.

Ekane is researching the potential of quercetin, a naturally occurring product found in buckwheat and other plants, such as onions.

Meanwhile, iTeam member Nicole Garza, a junior human biology major, is investigating a completely different approach to fighting COVID-19. She is looking into therapeutic compounds that can stop the virus from attaching to the host. Right now, her focus is on emodin, a natural compound found in rhubarb and buckthorn and used in traditional Chinese medicines.

Since the beginning of the semester, the students have spent hours each week surveying the literature and exploring other compounds in search of approaches that block or mitigate the virus.

We share a vast article base, and Dr. Ellington brings top colleagues to our research meetings, where we are sort of poked and prodded, Garza said. Its like, OK, what can you do here? Have you thought of this? How is this going to work? Laughing, she said, Maybe poked and prodded arent the right words, but these thought-provoking questions are sort of the idea of research in itself.

This research area of natural therapeutics for COVID-19 is largely unexplored, and Ekane said that the work has been rewarding and challenging. As a future scientist, its crucial, she said. In approaching this problem you just have to have different angles its almost like a game and solving its the fun part.

Ogre-faced spider: These spiders lack ears, but they can still hear you, study says – WTVD-TV

§ October 30th, 2020 § Filed under Nanotechnology Journal Comments Off on Ogre-faced spider: These spiders lack ears, but they can still hear you, study says – WTVD-TV

Spooky season is here -- so let's talk about spiders.

Ogre-faced spiders are believed to have the largest eyes of all known spider species, and they are known for their reported ability to see in the dark 2,000 times better than humans. That formidable eyesight, however, is just one of the sensory tools these arachnids can use when they hunt for food, a new study has revealed.

Through laboratory tests and observations in the field, the scientists showed that auditory stimuli in the same low frequency range as the wing beats of moths, mosquitoes and flies prompted the spiders to perform a "backward strike," one of their signature hunting moves.

This, according to the researchers, showed that the spiders use auditory cues to detect and capture flying prey.

"These spiders are a gold mine of information that have just gone untapped for a really long time," said study coauthor Jay Stafstrom, a postdoctoral researcher in neurobiology and behavior at Cornell University.

"The visual capabilities that they possess are off the map, and now, showing they can hear quite well, I think there's a lot more to understand about them going on in the future."

Like 'Jekyll and Hyde' Ogre-faced spiders are tropical critters found all over the world, including in the US, where they are present in Southern states like Florida.

You are unlikely to have noticed them in your backyard though, as they spend the day hours camouflaging as plant fronds, and only become active at night.

"The metaphor is Jekyll and Hyde," senior study author Ronald Hoy, a professor of neurobiology and behavior at Cornell, told CNN.

"By day, this creature acts dead. By night, this creature kills, preys, hunts. Its personality is set by the sun or the moon."

Ogre-faced spiders strike forward to capture prey below them, and strike backward to capture prey flying above them, Stafstrom said.

The two hunting methods rely on different senses, he explained.

"It seems to be that there's this nice partition of sensory systems where they are depending on vision to catch things off the ground specifically, and their ability to hear allows them to catch things out of the air."

Spiders don't have ears, but ogre-faced spiders are able to listen to sounds through receptors on their legs, including leg hairs, according to the researchers.

Sounds and threat detection Ogre-faced spiders reacted differently to sounds depending on their frequency, the study showed.

They would perform a "backward strike" to hunt for food in response to low frequency sounds in the same range as the wing beats of animals they prey upon. But when they heard high frequency sounds matching the range of bird calls, the spiders didn't move.

This doesn't mean the spiders couldn't hear sounds at high frequencies -- lab experiments the scientists conducted to monitor the spiders' brain activity in response to sounds confirmed they could, in fact, hear them.

Rather, the scientists suspect the spiders might ignore these sounds in self-defense, something they are looking to investigate further in the future.

"We know that birds eat a lot of spiders. I've seen a lot of birds in the palms that these spiders are in, and they happen to chirp in these high frequency ranges that these spiders can detect. So it might be an early warning sign that, OK, something might be coming to eat me soon," Stafstrom said.

The process of inserting electrodes into a spider's brain without killing it requires highly skilled prep work and "a watchmaker's hand," Hoy said.

He credited study coauthor Gil Menda, a postdoctoral fellow at Cornell's department of neurobiology and behavior, with this special talent.

Looking for spiders in their natural habitat The researchers also conducted observations in the field, studying the spiders' behavior in their natural habitat.

Hanging out with nocturnal spiders in their habitat is not the most comfortable experience, but Stafstrom does it with a passion.

For this study, he spent a week in the woods in Gainesville, Florida, equipped with a headlight, a Bluetooth speaker to play sounds for the spiders through his smartphone, and a camera to film their reactions.

As a doctoral student at the University of Nebraska - Lincoln, "I was down in Florida by myself, in a tent, for two months, in the middle of summer. It was rough, my sleeping schedule was very weird, but it's definitely the best way to study these spiders," he said.

During a different field mission in Costa Rica, Stafstrom was actually bitten by an ogre-faced spider.

"I might have the world record of the only person to have ever been bitten by these spiders," Stafstrom said.

The bite was harmless, he said -- just itchy for some time.

Spiders and tech There is still so much we don't know about spiders, and that's a gap we need to fill, according to Hoy and Stafstrom.

Studying how spiders and other small animals are able to see and hear can further new discoveries and nanotechnology applications, the researchers argued.

"If we can figure out the equipment they are using, and how they are processing information, we should be able to translate that through biomimicry into better bio-sensors, better directional microphones, or visual processing algorithms," Stafstrom said.

"The point is any understudied, underappreciated group has fascinating lives, even a yucky spider, and we can learn something from it," Hoy added.

Summary

Sensors have become indispensable in many industries because they provide vital information about parameters that include temperature, position, chemistry, pressure, force and load, and flow and level, and thus affect products, processes and systems. As technological advances in electronic control systems increase the efficiency of sensors, users are calling for advances in sensor accuracy, reliability, response time, robustness, miniaturization and communication capability. The sensor industry is robust and is expected to experience sound growth during the five-year forecast period.

Advances in micromachining have made it possible to produce micron-sized devices on a silicon wafer-a process that is very attractive for large-volume applications using mass production processes. This technology is particularly important in the sensor market since silicon has been shown as a very good material for use in sensors.

In the near future, the manufacturing costs and power consumption of wireless sensors will decrease, and wireless sensors will be fully integrated into wireless networks, replacing hardwired configurations. A broad spectrum of wireless communications hardware and software is already available, and the communication industry is the largest consumer of this technology, primarily in mobile phones and base stations. Fiber optic sensors will also play a role in networks and communications.

Magnetic field sensors will play a role in magnetic storage media and customer terminals. Photodetectors for local area networks (LANs) will also see growth in regional, municipal and longdistance network applications. Nanotechnology, which involves manipulating and harnessing chemical reactions and molecular processes of living cells in designs aimed at specific technological functions, will experience strong growth within the sensor market, especially for chemical detection.

Among the industrial sensor segments, pressure, force and load, and level sensors will experience strong growth. Image sensors will experience the highest growth because of their increased use in smartphones and many other portable devices. Biosensors and chemical sensors will also experience growth in the wake of terrorist threats to key industrial facilities such as chemical plants and due to increased use in medical applications.

Small companies account for the majority of companies within the sensor manufacturing business. Most companies pursue a focused strategy, but competitive and technological pressures are leading to consolidation and increasing concentration. However, the semiconductor industry is attempting to recapture its intensive capital investment by developing sensor solutions to address large-scale highvolume consumer-related applications. This will allow specialized industrial sensor manufacturers time to develop strategies for dealing with the competition. There are also opportunities for new entrants into the business, especially in MEMS. Further, companies with valuable intellectual property and strong customer bases make attractive acquisition candidates.

"Father of Green Medical Nanotechnology" Featured in the Latest Episode of From Campus to Commerce – PRNewswire

§ October 29th, 2020 § Filed under Nanotechnology Journal Comments Off on "Father of Green Medical Nanotechnology" Featured in the Latest Episode of From Campus to Commerce – PRNewswire

TAMPA, Fla., Oct. 28, 2020 /PRNewswire/ -- The National Academy of Inventors (NAI) has released its sixth video documenting the path from university discovery to public marketplace. This episode in the From Campus to Commerceseries highlights silver nanoparticle technology from the University of Missouri (Mizzou) developed by Dr. Kattesh Katti.

Katti is the recipient of the Hevesy Medal, a highly regarded award in Nuclear Sciences and Medicine. He is also globally known as the "Father of Green Medical Nanotechnology" for his pioneering work combining non-toxic nanoagents with traditional Ayurvedic-Holistic Medicine, used by 65-80 percent of the world's population as a primary source of health care.

In the video, Katti is seen in his lab discussing the impetus for his chosen work. "I wanted to create one product with dual actions of antibiotic/anti-viral properties so that people don't have to use several different agents to decontaminate infected areas."

His discoveries have been enormously successful, especially the timely product NanOLife sanitizer, which kills BOTH bacteria and viruses, including COVID-19.

Over the past three decades, Katti's work has also focused on molecular imaging and therapy in oncology. His gold-based nanomedicine is being used in cancer therapy today. In an NAI webinarearlier this month, he explained that gold, unlike many delivery mechanisms, is non-toxic to the body.

Katti has been recognized by the United Nations/IAEA as the Global Expert in 'Green Nanotechnology' and has won many awards such as the 2016 Person of the Year in Science. He is a Fellow of the National Academy of Inventors as well as a professor at Mizzou.
