Dec 24, 2022 (Nanowerk News) Marvel at the tiny nanoscale structures emerging from research labs at Duke University and Arizona State University, and it’s easy to imagine you’re browsing a catalog of the world’s smallest pottery. A new paper reveals some of the teams’ creations: itty-bitty vases, bowls, and hollow...
Shrinking hydrogels enlarge nanofabrication options
Dec 23, 2022 (Nanowerk News) Carnegie Mellon University’s Yongxin (Leon) Zhao and the Chinese University of Hong Kong’s Shih-Chi Chen have a big idea for manufacturing nanodevices. Zhao’s Biophotonics Lab develops novel techniques to study biological and pathological processes in cells and tissues. Through a process called expansion microscopy, the...
Researchers show a new way to induce useful defects using invisible material properties
Dec 23, 2022 (Nanowerk News) Much of modern electronic and computing technology is based on one idea: add chemical impurities, or defects, to semiconductors to change their ability to conduct electricity. These altered materials are then combined in different ways to produce the devices that form the basis for digital...
Researchers zoom in on battery wear and tear
Dec 23, 2022 (Nanowerk News) From the moment you first use it, a new lithium-ion battery is degrading. After a few hundred charge cycles, you’ll notice — your phone, laptop or electric car battery wears out more quickly. Eventually, it stops holding a charge at all. Researchers at the University...
Novel near-infrared light detection method using upconversion nanomaterials
Dec 23, 2022 (Nanowerk News) Associate Professor Ayumi Ishii of Teikyo University of Science with her team members has developed a new near-infrared light sensor by using a material that converts weak near-infrared light to visible light (Advanced Photonics Research, "Upconverting Near-infrared Light Detection in Lead Halide Perovskite with Core-shell...
the disruptive technology you didn’t see coming
Dec 23, 2022 (Nanowerk News) Robots and autonomous cars will have eyes that see much more than the human eye is capable of, a review of the growing field of meta-optics has found. Meta-optics is advancing science and technology far beyond the 3000-year-old optical paradigm that we rely on for...
New X-ray imaging technique to study the transient phases of quantum materials
Dec 23, 2022 (Nanowerk News) The use of light to produce transient phases in quantum materials is fast becoming a novel way to engineer new properties in them, such as the generation of superconductivity or nanoscale topological defects. However, visualizing the growth of a new phase in a solid is...
Researchers have cut the world’s smallest Christmas record (w/video)
Dec 23, 2022 (Nanowerk News) Measuring only 40 micrometres in diameter, researchers at DTU Physics have made the smallest record ever cut. Featuring the first 25 seconds of the Christmas classic “Rocking Around the Christmas Tree”, the single is cut using a new nano-sculpting machine – the Nanofrazor – recently...
Researchers use 3D bioprinting to create eye tissue
Dec 23, 2022 (Nanowerk News) Scientists used patient stem cells and 3D bioprinting to produce eye tissue that will advance understanding of the mechanisms of blinding diseases (Nature Methods, "3D outer retina barrier uncovers RPE-dependent choroidal phenotype in advanced macular degeneration"). The research team from the National Eye Institute (NEI),...
