Jul 15, 2022 (Nanowerk News) In the face of low electrolytic water splitting catalytic activity, the development of efficiency and stable electrolytic catalyst for hydrogen evolution reaction is critical necessary. Moreover, the rather high price with insufficient supply of noble mental namely platinum and palladium has become the obstacle of...
Microparticles could be used to deliver ‘self-boosting’ vaccines
Jul 15, 2022 (Nanowerk News) Most vaccines, from measles to Covid-19, require a series of multiple shots before the recipient is considered fully vaccinated. To make that easier to achieve, MIT researchers have developed microparticles that can be tuned to deliver their payload at different time points, which could be...
Why perovskites could take solar cells to new heights
Jul 15, 2022 (Nanowerk News) Perovskites hold promise for creating solar panels that could be easily deposited onto most surfaces, including flexible and textured ones. These materials would also be lightweight, cheap to produce, and as efficient as today’s leading photovoltaic materials, which are mainly silicon. They’re the subject of...
Atomic level deposition to extend Moore’s law and beyond
Jul 15, 2022 (Nanowerk News) Moore’s law has driven the semiconductor industry to continue downscaling the critical size of transistors to improve device density. At the beginning of this century, traditional scaling started to encounter bottlenecks. The industry has successively developed strained Si/Ge, high-K/metal gate, and Fin-FETs, enabling Moore's Law...
a new and easy-to-use webserver to identify genome edited cells
Jul 15, 2022 (Nanowerk News) Diseases of genetic cause can be investigated by inducing the respective mutations in cell lines that are then used to model human diseases. The overall aim is to elucidate underlying mechanisms, interactions with environmental factors and ideally to find curative strategies. A crucial step in...
An efficient electrochemical intercalation method for high-yield production of TMD nanosheets
Jul 15, 2022 (Nanowerk News) Two-dimensional (2D) transition metal dichalcogenides (TMDs), an emerging class of materials that can be used as semiconductors and insulators, have promising potential in various applications due to their unique properties. But the reliable production of these atomically thin 2D materials has been challenging. A research...
First synthetic mechanosensitive potassium channel
Jul 15, 2022 (Nanowerk News) Intrigued by the properties of ion channel proteins commonly observed in cells, Tokyo Tech researchers have developed the first synthetic mechanosensitive potassium channel using a newly developed aromatic fluorinated amphiphilic cyclophane. Displaying both “stimuli responsiveness” and “selective ion transport” abilities, their new ion channel could...
MXene in complex 3D device architectures
Jul 14, 2022 (Nanowerk News) Despite being only a few atoms thick, MXene packs a powerful punch. This class of single layer, two-dimensional (2D) nanomaterials exhibits desirable properties like excellent thermal and electrical conductivity, heat resistance and high specific surface area. These characteristics promise to revolutionize high-performance electronic devices and...
Atomically-smooth gold crystals help to compress light for nanophotonic applications
Jul 14, 2022 (Nanowerk News) KAIST researchers and their collaborators at home and abroad have successfully demonstrated a new platform for guiding the compressed light waves in very thin van der Waals crystals. Their method to guide the mid-infrared light with minimal loss will provide a breakthrough for the practical...
Cyborg collaboration finds 40,000 ring galaxies
Jul 14, 2022 (Nanowerk News) Human and machine intelligence worked together to find 40,000 ring galaxies, scientists at the National Astronomy Meeting will announce this week. Dr Mike Walmsley of the University of Manchester and the Galaxy Zoo collaboration will present the new work, describing how this “cyborg” approach measured...
