Nanomaterials: the materials of the future

§ August 27th, 2021 § Filed under Nanomaterials Comments Off on Nanomaterials: the materials of the future

Nanotechnology and the development of nanomaterials have had a great impact on the fields of science and engineering, influencing future technologies and improving industrial solutions. In this article we explain what nanomaterials are, how they are obtained and their applications.

Nanomaterials are materials that are tiny in size and smaller in scale than 100 nm, i.e. up to 100,000 times smaller than the diameter of a human hair.

Nanomaterials can be of natural origin, such as smoke, soot and blood proteins, or they can be man-made. These engineered nanomaterials are designed to achieve certain specific functions, such as increasing strength, chemical reactivity or conductivity. This field of study has exploded in the last decade, as it presents enormous possibilities in engineering, industry, robotics, biomedicine and the energy sector, and occupies a fundamental place in the design of many materials, devices and structures.

Nanomaterials can be created from minerals or chemicals and their physicochemical properties are different than when they are micro- or macro-sized. The composition, particle size, shape, surface coatings and bond strength of the particles change. Why?

As the size is reduced at the nanometer scale, the exposed surface area increases, which favors greater interaction between nearby atoms and molecules, leading to various attractions and repulsions that cause surface, electronic and quantum effects, affecting the optical, electrical and magnetic behaviors of the materials. This means that a small amount of nanomaterial can significantly modify and improve the properties of other materials. An example of this are polymers with carbon nanotubes, which make the doped material lighter, mechanically stronger and more functional than a metal.

Nanomaterials, as we will see below, are classified according to their dimensions:

Nanomaterials of dimension 0 are considered nanoparticles and all their dimensions are within the nanoscale. Fullerenes, inorganic nanomaterials such as gold and silver nanoparticles, nanowires, nanodiamonds or quantum dots (semiconductor crystals) belong to this group.

Two dimensions are within the nanoscale. This classification includes carbon nanotubes and carbon nanofibers. The latter are applied as additives, for example, in polymer matrices to improve their properties, as well as improve electrical conductivity in adhesives and paints without modifying their rheological properties and prevent corrosion of the materials they coat.

One of the three dimensions is within the nanoscale and they are in the form of a sheet. They include graphene, which has great potential for application in different fields such as electronics, nanoparticles and nanocoatings.

Materials that have no dimensions at the nanoscale, so that electrons are not confined and can move freely. Within this typology are nanostructured materials, nanoparticle dispersions and multilayers.

Nanomaterials have always existed, but techniques for creating, manipulating and engineering materials at this scale have only been developed in the last few decades thanks to technological innovations, such as the scanning tunneling microscope, which allow work at the nanoscale. So how are nanomaterials manufactured? Mainly, there are two processes:

This technique consists in the fabrication of nanomaterials from larger scale materials that are scaled down to the nanometer scale. It starts with large pieces of material and thanks to physicochemical processes they are decomposed until the desired nanomaterial is achieved. Depending on the substance, this process can be relatively simple. Some metallic nanoparticles, for example, can be crushed from microparticles.

The second group of fabrication processes involves the construction of nanostructures, atom by atom or molecule by molecule. Despite being more complex, the degree of precision achieved with this technique is greater than that which can be achieved with the previous one, because thanks to microscopes it is possible to place and assemble individual atoms and molecules in a specific place.

The use of nanomaterials spans a wide range of sectors, from healthcare and cosmetics, electronics and transportation to environmental conservation and the energy industry. Nanoengineered materials are designed to have increased structural strength, chemical sensitivity, conductivity and improved properties as a whole, generating great potential in materials innovation.

One of the most important applications is offered by carbon nanotubes, a nanomaterial that has the highest strength-to-weight ratio of any known substance, also has higher thermal conductivity than diamond and better electrical conductivity than copper and are extremely light, making them the perfect material for aircraft construction. Similarly, the enormous surface area of carbon nanotubes allows them to be used as electrodes in batteries and capacitors, providing greater electrical and mechanical stability than other materials.

Nanomaterials can also be used as lubricant additives, as they have the ability to reduce friction in moving parts, and even worn parts can be repaired with self-assembled nanoparticles. Advances like this give us more control over the materials we work with, unlocking new capabilities that can change the way we approach forensic engineering problems.

The structures and properties of materials can be improved through these nano-fabrication processes. For example, cooling properties can be improved thanks to nanomaterials or stronger, lighter, durable, water-repellent, anti-reflective, self-cleaning, UV-resistant, infrared-resistant, anti-fog, anti-microbial, electrically conductive, etc. materials can be created and different types of materials such as metal, glass or plastics can be processed. Taking advantage of these properties, current products made with nanomaterials range from tennis rackets, catalysts for refining crude oil to the detection and identification of biological and chemical toxins.

In the bio-health sector, nanomaterials are used for the administration of chemotherapy drugs to directly eradicate cancerous growths. They also offer solutions for diagnosis, thanks to the detection of biomarkers by means of nanoprobes, and provide a breakthrough in genomic studies.

On the other hand, in the cosmetics industry, titanium oxide nanoparticles are capable of providing better protection against UV rays than traditional sunscreens. Nanomaterials are also set to introduce a number of advantages in the electronics and computer industry. Their use will make it possible to increase the precision of electronic circuit construction at the atomic level, which will help in the development of numerous electronic products. Currently, many high-performance electronic devices are based on nanotechnology, such as Quantum Dot (QD) technology for LED displays and smartphones.

Nanomaterials have also improved the energy sector, thanks to energy savings. For example, solar panels use nanoparticles to improve their efficiency. In the case of wind turbines, the larger the blade the more electricity can be generated, so stronger and lighter nanomaterials are used. They can also fulfill essential environmental functions, for example, it has been discovered that graphene can filter common salts from water to make it drinkable, a solution that could lead to the desalination and purification of seawater for consumption.

Nanotechnology and nanomaterials are one of the fastest growing and potential markets in any sector. Do you want to apply this technology in your business? Contact our materials innovation team, our experts will study your case to offer you an effective and innovative solution.

Updating the PLOS ONE Nanomaterials Collection Author Perspectives, Part 2 – EveryONE – PLoS Blogs

§ August 27th, 2021 § Filed under Nanomaterials Comments Off on Updating the PLOS ONE Nanomaterials Collection Author Perspectives, Part 2 – EveryONE – PLoS Blogs

In July, we updated our Nanomaterials Collection, featuring papers published over the past few years in PLOS ONE. This collection showcases the breadth of the nanomaterials community at PLOS ONE, and includes papers on a variety of topics, such as the fabrication of nanomaterials, nanomaterial-cell interactions, the role of nanomaterials in drug delivery, and nanomaterials in the environment.

To celebrate this updated collection, we are conducting a series of Q&As with authors whose work is included in the collection. Next out is our conversations with Lauren Crandon from OnTo Technology and Robert Zucker from the U.S. Environmental Protection Agency. In this Q&A, they discuss the importance of understanding the environmental fate of nanomaterials, new technology development, and their experiences of making new discoveries in the lab. We will be adding more author interviews over the next few weeks, so please do keep checking back.

Lauren Crandon OnTo Technology

Lauren Crandon is a Research and Development Engineer with OnTo Technology in Bend, OR. She develops technology to recycle lithium-ion batteries, including nanomaterials. She received her Ph.D. from Oregon State University in Environmental Engineering, where she researched the environmental fate and impacts of nanomaterials.

Lauren Crandons paper in the Nanomaterials Collection: Crandon LE, Boenisch KM, Harper BJ, Harper SL (2020) Adaptive methodology to determine hydrophobicity of nanomaterials in situ. PLoS ONE 15(6): e0233844.

What motivated you to work in this field?

LC: I knew I wanted to study the environmental implications of emerging contaminants. When I first walked into the Harper Nanotoxicology Lab at Oregon State, I got so excited about nanomaterials. I learned that more and more fields in technology, medicine, and industry were using nanoparticles and that these would all be eventually released into the environment. In our lab, we looked at the implications of this at both the small scale (within individual organism) and the large scale (how far downstream nanoparticles will end up). If we can develop a good understanding of fate, transport, and toxicity, we can responsibly develop nano-enabled technology for the future.

Nanomaterials research has increased in popularity over the past few years as a research topic. Do you envision that the field can continue to grow in this way, and do you see any challenges on the horizon?

LC: I absolutely believe the field of nanomaterials will continue to grow. For example, lithium-ion batteries are starting to use nanomaterials to improve performance and nanoparticle-based sunscreens are becoming more popular due to concerns with their chemical alternatives. I think we will also see exciting breakthroughs in nanomedicine, among other fields. The main challenge will continue to be evaluating human and environmental safety at end-of-life for these applications. It is difficult to establish standards and regulations, since the fate and behavior of nanomaterials depends on their environment. However, this will be important for sustainable use.

Can you tell us about an experience during your research, whether in lab or at the computer or in conversation etc., where something finally clicked, or worked?

LC: Yes! I was collaborating with a toxicology graduate student in my lab to compare the toxicity of Cu and CuO nanoparticles in zebrafish. The CuO NPs were much less toxic, but we could not explain why. They dissolved more Cu+2, which was generally accepted to be the toxic mechanism. When I applied one of the standard assays I was working on to measure reactive oxygen species (ROS), the trends matched! Cu NPs generated much more ROS than CuO, which explained the higher toxicity. Applying a standardized test to NPs in a specific testing environment allowed us to model and predict toxicity. I spent the rest of my graduate work continuing to standardize rapid assays for commercially used nanoparticles and correlating my results with their toxicity. I hope this can help us predict the potential risks of materials as they enter the market.

Is there a specific research area where a collaboration with the nanomaterials community could be particularly interesting for interdisciplinary research?

LC: I am very excited about applications of nanomaterials in energy storage devices and medicine. I hope that as these materials continue to enter the market, nanotoxicology research will continue to be funded and part of the story. Nanomaterials offer novel properties that bring major benefits but also do not always follow conventional toxicology. I would like to see collaboration with the technology industry and environmental toxicology to responsibly produce the next generation of novel materials.

Robert Zucker U.S. Environmental Protection Agency

Dr. Robert Zucker is a Research Biologist at the U.S. Environmental Protection Agencys Center for Public Health and Environmental Assessment. His research involves applying biophysical technologies of imaging and flow cytometry to reproductive toxicology questions.

Robert Zuckers paper in the Nanomaterials Collection: Zucker RM, Ortenzio J, Degn LL, Boyes WK (2020) Detection of large extracellular silver nanoparticle rings observed during mitosis using darkfield microscopy. PLoS ONE 15(12): e0240268.

What route did you take to where you currently are in your career?

RZ: I obtained a BS in physics from The University of California, Los Angeles (UCLA) and obtained a masters degree at UCLA in the Laboratory of Nuclear Medicine and Radiation Biology in the field of biophysics and nuclear medicine. I also received my PhD in biophysics at UCLA studying biophysical separation and characterization of hematological cells. After graduating from UCLA, I did a two-year Post-Doc at the Max Planck Institute in Munich Germany in immunology. When I returned to America, I became a principal investigator at the Papanicolaou Cancer Institute and an adjunct associate professor at the University of Miami for 12 years. In this position, I was involved in cancer research and was a member of the Miami sickle cell center. My next position was at the EPA in Research Triangle Park, NC, applying biophysical technologies of imaging and flow cytometry to reproductive toxicology questions.

What emerging topics in your field are you particularly excited about?

RZ: Flow cytometry has been around for over 50 years. Recently, the technology has been improved by using five lasers with 64 detectors. This provides a system with better resolution. In addition, the software incorporated into the system allows the removal of autofluoresence noise to increase the detection of cells or particles.

Optical microscopes, cameras and equipment have improved to allow scientists to easily obtain digital images, which are high resolution. The new microscopes are automated allowing the scientist to design and achieve experiments that were not previously feasible. For example, the current microscope allows us to use widefield confocal microscopy on 2D images that can be deconvolved with software built into the system for higher resolution. It is quicker than point-scanning confocal microscopy. The machines can obtain sequential measurements over time on one field or take images from multiple fields.

How important are open science practices in your field? Do you have any success stories from your own research of sharing or reusing code, data, protocols, open hardware, interacting with preprints, or something else?

RZ: It is important to follow ones scientific instinctsthe EPA is an organization that allows this freedom to their investigators to research projects of interest to the Agency. I have two success stories to share from my own research.

Success story #1: In the field of nanoparticles, I observed that TiO2 was extremely reflective using darkfield microscopy. Using flow cytometry, granulocytes, monocytes, and neutrophils can be identified based on size (forward scatter) and internal structure (side scatter) from the granules contained in the neutrophils. Can this scatter signal be used to detect a dose response of uptake of nanoparticles by a cell? To try to answer this question, we used two concentration of TiO2 in an experiment, and a dose response was observed with these two-concentration compared to controls. This procedure has subsequently been reproduced by a number of investigations with various types of metal nanoparticles. One of our papers was published in PLOS One and compared the effect of different coating of silver particles coatings on uptake and toxicity by mammalian cells.

Success story #2: The confocal microscope allows scientists to see embryo and reproductive structures in 3D using fluorescence staining technology. By applying very old technologies used to clear tissues, we were able to see very deep into tissues. This procedure allowed the internal structures of reproductive tissues and developing embryos to be observed. The data were used to support the hypothesis that studied how the chemicals affected these tissues.

If you could dream really big, is there a particular material, function or material property that seems far away at the moment, but you think could be attained in the future?

RZ: My dream would be to use the current spectral flow cytometer to predict 1) the effects of microplastics on mammalian cells 2) to detect the effects of climate change on cyanobacteria growth and toxin production 3) to spectrally detect microplastics in water. I would want to provide a simple imaging test to 4) detect microplastics in water by their higher reflectivity 5) to provide an instant imaging quantitation of the amount of Algae and Cyanobacteria in a water sample based on differential excitation fluorescence, and 6) use spectral features of photosynthesis fluorescence and autofluoresence to determine the health of plants and cyanobacteria and then relate this data to the environment.

Highly conductive and elastic nanomembrane for skin electronics – Science Magazine

§ August 27th, 2021 § Filed under Nanomaterials Comments Off on Highly conductive and elastic nanomembrane for skin electronics – Science Magazine

Thin, sensitive skin electronics

The properties of the human sense of touch, including high sensitivity to differences in temperature, pressure, or surface roughness, are challenging to replicate in robotics because skin materials must be highly conductive, stretchable, and thin. Jung et al. developed a process to assemble nanomaterials as a monolayer that is partially embedded in an ultra-thin elastomer. The process works by depositing a mixed solvent containing nanostructured silver and/or gold, along with elastomer, onto deionized water. This results in a layer of nanoparticles residing at the interface coating with elastomer, which is further densified by the addition of surfactant. The process is scalable, and the resulting elastomer membranes can be transferred to other substrates.

Science, abh4357, this issue p. 1022

Skin electronics require stretchable conductors that satisfy metallike conductivity, high stretchability, ultrathin thickness, and facile patternability, but achieving these characteristics simultaneously is challenging. We present a float assembly method to fabricate a nanomembrane that meets all these requirements. The method enables a compact assembly of nanomaterials at the wateroil interface and their partial embedment in an ultrathin elastomer membrane, which can distribute the applied strain in the elastomer membrane and thus lead to a high elasticity even with the high loading of the nanomaterials. Furthermore, the structure allows cold welding and bilayer stacking, resulting in high conductivity. These properties are preserved even after high-resolution patterning by using photolithography. A multifunctional epidermal sensor array can be fabricated with the patterned nanomembranes.

Nanosynth Group sees big opportunity from nano-materials as it pushes ahead with refreshed strategy – Proactive Investors UK

§ August 27th, 2021 § Filed under Nanomaterials Comments Off on Nanosynth Group sees big opportunity from nano-materials as it pushes ahead with refreshed strategy – Proactive Investors UK

Nanosynth Group PLC (), the company formerly known as Remote Monitored Systems, is to claw back some money spent on a recalcitrant mask manufacturing machine.

The group said terms have been agreed with Lemu Group, the supplier of a mask manufacturing machine to Pharm 2 Farm Limited (the company's main subsidiary), to return the machine to Lemu.

The agreement is a recognition that despite the best efforts of Pharm 2 Farm (P2F) and Lemu to overcome technical issues with the machine, it has not been possible for the machine to perform as originally expected.

Lemu will repay 180,000 to P2F by the end of next month. The remaining 66,000 of the 246,000 that has been paid to Lemu will be paid contingently upon a re-sale by Lemu of the machine to a third party, with the intention being that this is achieved by the end of this year. Egremont Capital has been appointed to assist with the sale, for which they will receive a commission.

Does the Potential of Nano Dimension Stock Outweigh Its Risks? – Motley Fool

§ July 4th, 2021 § Filed under Nanomaterials Comments Off on Does the Potential of Nano Dimension Stock Outweigh Its Risks? – Motley Fool

Given its current state, investors might struggle with the investment case for Nano Dimension (NASDAQ:NNDM) even though it has drawn the interest of Cathie Wood's ARK Invest funds. While the company holds the potential to upend a vital part of the tech industry, customers seem slow to warm to its product. For this reason, investors need to more closely weigh Nano Dimension's prospects against its ongoing challenges before deciding to open a position.

Image source: Getty Images.

Israel-based Nano Dimension develops 3D-printed electronic systems. It combines nanomaterials with 3D inkjet and 3D software to manufacture multilayer printed circuit boards (PCBs).It produces these circuit boards through its DragonFly LDM system, which applies lights-out digital manufacturing (hence the "LDM"), described by the company as the "only comprehensive additive manufacturing platform" for making electronic circuitry with 3D printing.

Procurement compliance company Beroe estimates the size of this industry at $58 billion in 2020, with the potential to reach $70 billion by 2024. Nonetheless, the circuit board industry draws relatively little interest from investors. According to industrial sourcing and marketing company Thomas, the largest circuit board manufacturer is Jabil, which receives little investor coverage despite employing about 260,000 people and supplying clients such as Appleand Amazon.

Now, Nano Dimension can replicate that company's manufacturing process within a 3D printing unit, posing a serious competitive threat to manufacturers such as Jabil.As longtime tech industry observers will recall, today's HP printer can print brochures and newsletters that would have required the services of a commercial printer in the previous century. Likewise, Nano Dimension's 3D printer allows a small or medium-sized business to create circuit boards in-house.

This could reduce the potential client base of large manufacturers. Moreover, it could also allow businesses and entities of nearly all sizes to produce specialty electronic products in small batches. That could facilitate the production of new devices from small and large manufacturers alike. Among its more recent new clients are defense agencies, contractors, and the U.S. military itself.

Furthermore, Nano Dimension holds about $1.4 billion in liquidity. This gives it a large amount of capital that it can invest in acquisitions and product improvements. To that end, it bought Nanofabrica and DeepCube in April, moves that will likely improve its miniaturization and deep-learning capabilities, respectively.

Additionally, Nano Dimension also released its next-generation 3D printer, the DragonFly LDM 2.0, in May, and it plans to release two new generations of machines within the next 18 months.

Nonetheless, investors likely to feel encouraged by the value proposition might start to harbor doubts when realizing that the company remains in a very early stage of its development. Nano Dimension sold only 61 units between 2018 and 2020.

Its financials also reflect that early stage position. Revenue for the first quarter of 2021 came in at only $811,000. This is up from $702,000 in the year-ago quarter. Also, its net quarterly loss came to $9.3 million, significantly higher than the $3.5 million loss in the first quarter of 2020, as operating expenses more than doubled.

However, the quarterly year-over-year increase may point to a recovery. In fiscal 2020, Nano Dimension reported revenue of $3.4 million in 2020, a 52% decline from 2019 levels as sales suffered amid the pandemic. The drop also came at a time of rising operating expenses, especially general and administrative expenses, which surged more than sixfold. As a result, its operating loss in 2020 came to almost $36 million, an increase of about 240% from the nearly $15 million it lost in 2019.

Investors should also note that the company earned almost $2 million of its $3.4 million in 2020 revenue in the fourth quarter alone. That revenue level came in at about the same level as the just under $2 million earned in the fourth quarter of 2019, indicating that the company's recovery from the pandemic made significant progress in the last three months of 2020.

Although the company did not release Q2 or full-year 2021 guidance, analyst estimates point to continued increases as they predict sales of about $5 million in fiscal 2021. While that would mean an increase of nearly 50% from 2020 levels, many investors may still perceive the company's concept as unproven.

Without more significant sales numbers, the Israel-based company has turned to the issuance of more ADR shares for its financing. Today, more than 256 million shares trade on exchanges, and this count has risen exponentially. In July 2020, the shares outstanding stood at just over 46 million. Two years ago, that count was only 3.6 million. This share issuance was probably a major factor in the tech stock's drop from almost $18 per share in January to just below $5.50 in mid-May, though the share price has since risen.

NNDM data by YCharts

Its run-up has also brought with it valuation concerns, at least from one key perspective. The company's market cap now stands at just over $2.1 billion. Consequently, Nano Dimension sells for a price-to-sales (P/S) ratio of just over 250!

Still, this might mislead investors, because Nano Dimension's liquidity reflects most of the company's value. As a result, its price-to-book value ratio stands at around 1.4, well below the average S&P 500 book value multiple of 4.7.

Even with the risks, Nano Dimension's value proposition holds too much potential to ignore. Admittedly, the lack of sales and massive share issuances should rightly concern investors.

However, the opportunity for more-affordable specialty circuit boards could offer electronics manufacturing capabilities to small businesses in the same way that inkjet printers brought the power to create professional-looking publications to individuals. That prospect in itself could lead to crazy returns in the coming years.

This article represents the opinion of the writer, who may disagree with the official recommendation position of a Motley Fool premium advisory service. Were motley! Questioning an investing thesis -- even one of our own -- helps us all think critically about investing and make decisions that help us become smarter, happier, and richer.

Nanomaterial stores radicals to power photopolymerisation in the dark – Chemistry World

§ June 20th, 2021 § Filed under Nanomaterials Comments Off on Nanomaterial stores radicals to power photopolymerisation in the dark – Chemistry World

Functionalised carbon nitride nanomaterials capable of storing light energy in the form of long-lived radicals have made it possible for photoreactions to take place in the dark, new research shows.1

Photosynthesis, the process of converting light energy into electrochemical potential in plants and using it to drive reactions when dark has proven difficult to replicate in artificial systems. This is because photogenerated charge pairs tend to recombine after irradiation, which prevents photoreactions occurring in the absence of light.

On account of its ability to promote electronhole separation, a team surrounding Ze Zhang from the University of Science and Technology of China, predicted that C3N4-NH2 might stop charge pairs from recombining by trapping photogenerated electrons. Whilst electronhole separation under irradiation took place when the team probed the material experimentally, electron paramagnetic resonance spectroscopy (EPR) confirmed that C3N4-NH2 did not store electrons. Density functional theory calculations to determine the charge distribution of C3N4-NH2 revealed that modifying the structure by replacing a proton in the amino (NH2) group with a cyano (CN-) moiety gave a more positive charge distribution, given the enhanced interaction of the heptazine rings toward electrons.2 Heptazines are nitrogen-rich aromatic systems, meaning they are strongly electron-deficient and likely to hold on to electrons, making them ideal candidates for electron storage.

Irradiating the C3N4NHCN species resulted in a blue suspension and a g value of 2.0021 using EPR, which is characteristic of stored electrons. Upon exposure to air, the electrons immediately reacted, and the suspension changed colour. Neither the C3N4NH2 and C3N4N--CN suspensions were blue in colour or showed an EPR signal.

To investigate the electron storage ability of C3N4NHCN, the team varied the proportion of protonated and non-protonated units by changing the pH. This led them to conclude thatthe more NHCN groups present, the greater the EPR signal strength and the stronger the colour of the suspension. Further analysis of C3N4NHCN involved methylene blue, which Zhang explains was due to its significant absorption changes before and after accepting electrons, [meaning] it is helpful to determine the amount of electron storage. This investigation uncovered that C3N4NHCN with five layers could absorb all the methylene blue available after 10 minutes of irradiation, which was confirmed using EPR. The EPR signal intensity indicated that 50% of the stored electrons were still present after one month and available to participate in reversible addition-fragmentation chain transfer (RAFT) polymerisation. This process is initiated by electron transfer from C3N4NHCN to diphenyliodonium (DPI), which produces phenyl radicals that can react with the RAFT reagent to promote photopolymerisation. Relative to polymerisation under continuous light irradiation, fewer side reactions take place and the RAFT agent does not degrade, resulting in polymers with greater molecular weights.

Athina Anastasaki, based at ETH Zurich in Switzerland, whose research focuses on radical polymerisation remarks that the work provides a new tool for the synthesis of advanced functional polymers that can be used for a wide range of applications. Zhang says the team hope to continue to develop light energy conversion and storage materials and expand the application range of stored electrons.

Inventor creates new material that can keep buildings cool without air conditioning | TheHill – The Hill

§ June 20th, 2021 § Filed under Nanomaterials Comments Off on Inventor creates new material that can keep buildings cool without air conditioning | TheHill – The Hill

A Boston professor created an invention that reflects the heat off of rooftops and even sucks the heat out of homes and buildings and the real kicker is that it is 100 percent recyclable.

Yi Zheng, associate professor of mechanical and industrial engineering at Northeastern University, created cooling paper so that a building or home could essentially keep cool on its own, with no electricity required, according to Northeastern Universitys blog.

The paper can cool down a rooms temperature by as much as 10 degrees Fahrenheit a game-changing alternative to air conditioners that require a lot of electricity and money from home owners.

In the U.S. alone, where three-quarters of all homes have air conditioners, these appliances release roughly 117 million tons of carbon dioxide into the air each year. Air conditioners also use about 6 percent of all electricity produced in the U.S., and cooling down a home costs about $29 billion a year for homeowners.

Zhengs invention works through the porous microstructure of the natural fibers inside the cooling paper, which absorbs warmth and reemits it away from the building. The cooling paper itself is made out of common paper.

The light-colored material is part of Zheng's studies into nanomaterials. His idea was first sparked after seeing a bucket full of printing paper.

How could we simply transform that waste material into some functional energy material, composite materials? Zheng thought, according to Northeastern.

Zheng and his team used a high-speed blender from his home kitchen to turn the paper into a pulp and mixed it with the material that makes up Teflon.

The product can coat buildings and homes, reflecting solar rays away from the interior and even absorbing heat from cooking, electronics and human bodies out of the indoor space.

Even when the paper is recycled, it still performs as well as the original.

I was surprised when I obtained the same result, Zheng says. We thought there would be maybe 10 percent, 20 percent of loss, but no.

For his efforts, the American Chemical Society journal Applied Materials & Interfaces featured his invention, and Zheng won a National Science Foundation CAREER Award grant for his research.

PolyU develops biomimetic nanosheet for cancer therapy and imaging USA – PR Newswire India

§ June 4th, 2021 § Filed under Nanomaterials Comments Off on PolyU develops biomimetic nanosheet for cancer therapy and imaging USA – PR Newswire India

HONG KONG, May 31, 2021 /PRNewswire/ -- A research team from the Department of Applied Biology and Chemical Technology (ABCT) of The Hong Kong Polytechnic University (PolyU) has developed a novel type of biomimetic nanosheet with a multi-modal imaging function, which can track tumour development and treatment processes in real-time. By harnessing two emerging cancer therapies, namely immunotherapy and photothermal therapy, the biomimetic nanosheet enables effective and precise treatment of tumours, which will significantly improve the therapeutic outcome of tumours, reduce side effects and increase patients' survival rates. The research findings have been published in the prestigious international journal Advanced Science.

Professor Wing-tak WONG, Chair Professor of Chemical Technology of the ABCT of PolyU (also the Deputy President and Provost of PolyU), and his team started the research in 2018. Professor Wong said, "The biology and chemical experts of PolyU have been dedicated to new drug development over the years, and have achieved some significant breakthroughs especially in cancer treatment. The newly developed biomimetic nanomaterials developed by PolyU are part of our endeavours in fighting against cancer. By integrating two emerging cancer therapies, immunotherapy and photothermal therapy, with three imaging modalities for the first time, the novel biomimetic nanomaterials provide a practical design blueprint for the development of a new generation of cancer theranostics agents which have high targeting ability, efficacy and safety."

Synergistic therapy- Combining immunotherapy and photothermal therapy

New cancer treatments emerge since conventional cancer treatments like surgical therapy, chemotherapy and radiotherapy have different limitations and side effects. Dr Summy Lo Wai-sum from ABCT said, "Immunotherapy and photothermal therapy are emerging methods which are expected to provide more options for cancer treatment. The biomimetic nanosheets developed by our team allow us to combine these two methods for synergistic therapy. By applying the synergistic therapy in an experiment for colorectal tumour treatment, we found that it is more effective than single therapy and has fewer side effects on the human body."

The research team used 2D nanosheets (FePSe3) to develop a novel multifunctional nanomaterial for cancer theranostics. PD-1 (programmed cell death 1) exists on T cells, whereas PD-L1 (programmed cell death ligand-1) exists on tumour cells. Cancer cells inhibit the activation of the immune system and prevent T cells from attacking cancer cells through conjugating its PD-L1 with PD-1 on T cells. The team therefore loaded the FePSe3 nanosheets with anti-PD-1 peptide (APP), which can block the conjugation between PD-1 on T-cells and PD-L1 on cancer cells to achieve efficient immunotherapy. Without directly attacking the cancer cells, blockage of the interaction between the PD-1 and PD-L1 has been reported to revoke T cell functions, leading to enhanced antitumour immunity.

After coating with cancer cell membranes, the nanosheets will become a biomimetic nanomaterial with tumour cell membrane characteristics that provide effective camouflage, enabling them to target the tumour site efficiently. Once the biomimetic nanosheets are injected into the living bodies, the cell membrane enveloping the nanosheets will preferentially adhere to cancer cells and slowly peel away, revealing the nanomaterial to begin immunotherapy.

Dr Lo explained, "The innate immune system attacks foreign objects which makes it difficult for the drug-loaded nanomaterials to reach the tumour site.The cancer cell membrane has a tumour-targeting characteristic that will converge homologous cells. It explains why the biomimetic nanosheets become attracted to the cancer cells when they are in close proximity with the cancer cells duringblood circulation.In addition, the large specific surface area of the 2D nanomaterials is conducive to improving the drug loading ratio of the anti-PD-1 peptide, which will help with enhancing the therapeutic efficiency, as well as reducing the drug dosage and hence alleviating side effects."

On the other hand, the nanomaterials (FePSe3) chosen possess good photothermal conversion efficiency, and so they can convert near infrared laser irradiation into heat to kill tumour cells directly, thus achieving effective photothermal therapy. The heat can further promote immunotherapy by effectively inhibiting tumour growth, which results in a synergistic effect of immunotherapy and photothermal therapy.

Three imaging modes to help real-time monitoring of cancer treatment

The PolyU-developed biomimetic nanosheets can also achieve the goals of theranostics. By harnessing magnetic, optical and thermal properties,the FePSe3 nanomaterials enable three imaging modalities, namely magnetic resonance imaging (MRI), photoacoustic imaging (PAI) and photothermal imaging (PTI), for real-time tracing and tracking of the tumour sites and the nanosheets, in order to achieve multimodal diagnosis in cancer treatment.

PolyU's novel nanomaterial can facilitate theranostics by combining diagnosis, therapy and efficacy monitoring. It not only enables the imaging and treatment of tumours, but also the real-time monitoring of treatment outcomes. The PolyU team carried out experiments on mice bearing subcutaneous colorectal tumours to investigate the application in living animals.

The study showed that the tumour volume had significantly reduced after 25 days of synergistic therapy, whereas the survival rate of the mice was three times higher than that of the control groups.The major organs of the mice, including the heart, liver, spleen, lung and kidney, showed no obvious inflammation and damage, demonstrating high biosafety and low toxicity. The research team also utilised the MRI and photoacoustic imaging capabilities of the biomimetic nanosheet to observe the tumour for 24 hours, visualising the targeting and accumulation of the nano-theranostic material at the tumour site. Through photothermal imaging, it was observed that the nanomaterial can produce localised heat under near infrared laser irradiation within a few minutes. The experiment proved that PolyU-developed biomimetic nanosheets, with multi-modal imaging capability, canoffer accurate and comprehensive detection and evaluation of tumour development, ultimately achieving theranostics alongside synergistic therapeutic effects.

Dr Lo said, "In view of the fact that there is a lack of efficient and safe theranostics materials, PolyU's biomimetic nanomaterial has promising prospects in application. In future, our team will further expand the application of this nanomaterial to other cancer therapies and study the metabolism of the nanosheet in the living body, hoping that more cancer patients can benefit from new theranostic methods."
