1− Anti-SARS-CoV-2 multivalent neutralizing nanobodies

Though vaccination is enabling the resumption of some pre-pandemic activities in parts of the world, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is rapidly working its way around vaccines by mutating itself. Neutralizing nanobodies are important for treatment and immunity against SARS-CoV-2 and its novel escape mutants. Using a library of variable antibody fragments (nanobodies) derived from heavy chain antibodies, researchers identified next-generation anti-SARS-CoV-2 neutralizing antibodies. These nanobody-based SARS-CoV-2 antibodies provide easier manufacturability, increased versatility, smaller size, and the ability to bind to more than one target site to increase potency and resistance to viral escape mutants. The nanobodies are significantly smaller. They are therefore able to bind to the virus in more places than regular antibodies. Stable enough to be used in inhalers or nasal sprays, the nanobodies also offer a new option, aside from injected vaccines, for COVID-19 prevention and treatment. The researches are in animal testing now.

3−Ligand-engineered bandgap stability in mixed-halide perovskite LEDs

Physics researchers of the University of Oxford showed that binding of multidentate ligands to the surface of lead halide perovskite nanocrystals suppresses the formation of surface defects that result in halide segregation, yielding materials with efficient and color-stable red emission. The key function of the ligand treatment is to ‘clean’ the nanocrystal surface through the removal of lead atoms. This work that was published in the March issue of Nature journal exemplifies how the functionality of metal halide perovskites is extremely sensitive to the nature of the nanocrystalline surface and presents a route through which to control the formation and migration of surface defects. This is critical to achieving bandgap stability for light emission and could also have a broader impact on other optoelectronic applications—such as photovoltaics—for which bandgap stability is required.

4−Memristive spintronic neurons: combining two cognitive computing nano-elements into one

Researchers at Tohoku University and the University of Gothenburg have established a new spintronic technology for brain-inspired computing. So far, artificial neurons and synapses have been developed separately in many fields; this work which was published in Nature Material marks an important milestone: two functional elements have been combined into one. This work demonstrated the first integration of a cognitive computing nano-element - the memristor - into another spintronic oscillator. Using the memristor-controlled spintronic oscillator arrays, synaptic interactions between adjacent neurons could be tuned and they could program into mutually different and partially synchronized states. Memristor gating is therefore an efficient approach to input, tune and store the state of spin Hall nano-oscillator for non-conventional computing models.

5−Mimicking photosynthesis by new light-powered catalyst

By mimicking photosynthesis, MIT researchers have designed a new type of photocatalyst, known as a biohybrid photocatalyst, which contains a light-harvesting protein that absorbs light and transfers the energy to a metal-containing catalyst. The new photocatalyst can make pharmaceutical, agrochemical, and fuel synthesis more efficient and environmentally compatible. Biohybrid photocatalyst also demonstrated that unlike existing photocatalysts, can absorb all wavelengths of light. They combine two separate elements for increasing photocatalysis efficiency: one to harvest light and another to catalyze the chemical reaction. This work was supported as part of the Bioinspired Light-Escalated Chemistry (BioLEC) Energy Frontier Research Center and published in the Chem journal.

6−Multifunctional metamaterial nanogenerators for energy harvesting and active sensing

Researchers at the University of Pittsburgh have designed a new class of materials that are both sensing mediums and nanogenerators, and are poised to revolutionize the multifunctional material technology. This recently published research in Nano Energy describes a new metamaterial system that acts as its own sensor, recording and relaying important information about the pressure and stresses on its structure. The most innovative facet of the work is its scalability: the same design works at both nanoscale and megascale simply by tailoring the design geometry. While nearly all of the existing self-sensing materials are composites that rely on different forms of carbon fibers as sensing modules, this new concept relies on performance-tailored design and assembly of material microstructures offers a completely different, yet efficient, approach to creating sensor and nanogenerator material systems. This material can be used for a variety of civil, aerospace, and biomedical engineering applications.

8−New composite fabric against bacteria, viruses, and chemicals

A team of researchers from Northwestern University has developed a material that could change the current landscape of protective clothing. The composite fabric that is based on metal-organic frameworks (MOFs) has catalysts present in its cavities that are able to capture and deactivate toxic chemicals, viruses, and bacteria in a similar way to how sponges soak up water. Having a bifunctional material that has the ability to deactivate both chemical and biological toxic agents is crucial since the complexity to integrate multiple materials to do the job is high. The fabric works against SARS-CoV-2, gram-negative, and gram-positive bacteria whilst also degrading toxic nerve agents such as sulfur mustard gas. Results of the study have been published in the Journal of American Chemical Society (JACS).

9− New wearable device turns the body into a battery

Researchers at CU Boulder have developed a new, low-cost wearable device that transforms the human body into a biological battery. The device, described by scientists of the University of Colorado Boulder in the journal Science Advances is stretchy enough that you can wear it like a ring, a bracelet, or any other accessory that touches your skin. It also taps into a person’s natural heat—employing thermoelectric generators to convert the body’s internal temperature into electricity. These generators are in close contact with the human body, and they can use the heat that would normally be dissipated into the environment. While there are still kinks to work out in the design, Group researchers predict devices could appear on the market in five to 10 years.

10−Radio-frequency nanoelectromechanical systems against counterfeit goods

Many of legitimate manufacturing companies and distributors suffer from brand-name counterfeit goods. Researches in electrical and computer engineering department at the University of Florida overcame this problem based on radio-frequency (RF) nanoelectromechanical systems (NEMS) tags. Because of RF NEMS tiny size, and the nature of their constituents, make these tags largely immune to physical tampering or cloning and they cost just a few pennies each at most. This tags characterized by the differences between its measured resonant frequencies and the corresponding frequencies for an ideal tag. These differences are encoded as short binary strings, padded to a standard length, with one bit signifying whether the frequency offset of positive or negative in fact these strings provide a unique digital fingerprint for the tag.
