Sep 27, 2023 (Nanowerk News) A newly discovered nearby supernova whose star ejected up to a full solar mass of material in the year prior to its explosion is challenging the standard theory of stellar evolution. The new observations are giving astronomers insight into what happens in the final year...
3D Prints join the dark side and vanish
Sep 27, 2023 (Nanowerk Spotlight) 3D printing, also known as additive manufacturing, has opened new doors in design and manufacturing. The greatest resolution is achieved using a technique called direct laser writing (DLW), which focuses a laser into a photosensitive material to solidify microscopic 3D structures. One of the challenges...
Advancing atomic-scale technology
Sep 27, 2023 (Nanowerk News) A Case Western Reserve University-led team is working on technology that could dramatically improve electrical transformers and power converters in electric vehicles. To do that, researchers are focusing on what is known as “quantum sensing”—the atomic-scale technology made possible when scientists harness the smallest magnetic,...
Towards computational design of molecules with desired properties
Sep 25, 2023 (Nanowerk News) Prof. Alexandre Tkatchenko and his research team at the University of Luxembourg in collaboration with Cornell University and the Argonne National Laboratory have introduced a novel “freedom of design” principle in the chemical compound space (CCS) – the unfathomably vast space populated by all possible...
Researchers take a deep look at peroxisomal processes
Sep 26, 2023 (Nanowerk News) Every system has its waste disposal system. The cell organelles known as “peroxisomes” dispose toxic substances and fats in the human body, among other things, and, in doing so, they prevent serious illnesses. The “Pex” group of proteins (peroxisomes biogenesis factors) keep these “detox units”...
New nanozymes for efficient carbon capture
Sep 26, 2023 (Nanowerk News) Universitat Autònoma de Barcelona (UAB) researchers have developed minimal nanozymes with the capacity of capturing carbon dioxide (CO2) emitted in industrial processes and applicable to other environmental remediation processes, based on artificial molecular structures formed by the peptides of only seven amino acids. These new...
Fabrication of p-type 2D single-crystalline transistor arrays with Fermi-level-tuned van der Waals semimetal electrodes
Sep 26, 2023 (Nanowerk News) Professor Soon-Yong Kwon in the Department of Materials Science and Engineering and the Graduate School of Semiconductor Materials and Devices Engineering at UNIST, in collaboration with Professor Zonghoon Lee, has embarked on a pioneering research endeavor focusing on the development of high-performance p-type semiconductor devices,...
Thiol ligands modify metal nanocluster structures and optical properties
Sep 26, 2023 (Nanowerk News) Metal nanoclusters are tiny, crystalline structures up to two nanometers (2 x 10-9 meters) in diameter that contain a few to hundreds of metal atoms. Understanding the precise assembly of metal nanoclusters is paramount to determining how different structures affect the properties and molecular interactions...
Genetically engineered plastic-eating bacteria can give waste a new life
Sep 26, 2023 (Nanowerk News) A group of synthetic bacteria that can efficiently turn plastic waste into useful chemicals is presented in Nature Communications ("Engineering microbial division of labor for plastic upcycling"). These bacteria could help to tackle the growing problem of plastic pollution and produce valuable chemicals and products...
Transparent wood-based coating doesn’t fog up
Sep 26, 2023 (Nanowerk News) Researchers have developed a way to turn a waste material from wood into a bio-based transparent film that can be used for anti-fogging or anti-reflective coatings on glasses or vehicle windows. In addition to offering an alternative to the toxic synthetic materials currently used, this...
