https://phys.org/ en-us Latest news from National Tsing Hua University The extreme accuracy and speed of NBA three-pointer Stephen Curry's long-range shots are well known to basketball fans around the world, but accuracy and speed are also a focus of research in biochemical testing. Dr. Yen Ta-Jen, professor in the Department of Materials Science and Engineering, National Tsing Hua University, Taiwan, has published a paper about deep UV surface-enhanced resonance Raman scattering (DUV-SERRS) in the Journal of the American Chemical Society, in which he revises conceptions about light diffraction also creating a fast, accurate spectral application. It is currently undergoing clinical trials for use in rapid screening for cancer and other diseases, and also has potential applications in such areas as genome screening, biomedical engineering, polymer synthesis, forensics, environmental and food safety, pharmaceuticals, and materials analysis. https://phys.org/news/2022-06-substrate-deep-uv-surface-enhanced-resonance.html Analytical Chemistry Tue, 14 Jun 2022 14:33:37 EDT news574436009 A research team led by Professor Jyh-Ming Wu of the Department of Materials Science and Engineering at National Tsing Hua University (NTHU) in Taiwan has recently developed two composite piezoelectric materials extracted from common waste products. One is a new type of catalyst extracted from discarded rice husks and is capable of treating industrial wastewater 90 times quicker than the photocatalysts now in use. The other is a material extracted from discarded squid bones and has been used to produce a self-sanitizing transparent film suitable for use as a cover on mobile phone screens, elevator buttons, door handles, etc. https://phys.org/news/2021-07-composite-piezoelectric-materials-common-products.html Nanophysics Tue, 20 Jul 2021 08:02:51 EDT news545986967 Perovskite quantum dots are the rising stars of quantum emitters, but their inherent instability has hampered their development. Professor Hao-Wu Lin of the Department of Materials Science and Engineering, Associate Professor Chih-Sung Chuu of the Department of Physics, and Professor Richard Schaller of the Department of Chemistry at Northwestern University in the United States have jointly developed a perovskite quantum emitter with high stability and self-healing ability by a self-developed, simple, and economical procedure—spray-synthesis method. The unprecedented single-photon brightness of these quantum dots breaks the world-record, which makes them become the brightest room-temperature quantum emitter materials and constitute a major breakthrough in both quantum communication and quantum computing. https://phys.org/news/2021-05-team-self-healing-quantum-emitter-unprecedented.html Nanophysics Tue, 25 May 2021 07:24:02 EDT news541146237 It's widely known that submerging a pared apple in saltwater prevents oxidation and browning, but did you know that saltwater can also protect fragile quantum dot (QD) materials? A research team led by Prof. Chen Hsueh-Shih of the Department of Materials Science & Engineering at National Tsing Hua University in Taiwan has recently developed the world's first inkjet technique for using saltwater to encapsulate QD materials, which not only resists water and oxygen corrosion, but can also be uniformly printed as a flexible plastic film on a micro LED array for use in high-resolution bendable screens for mobile phones, glasses, etc. https://phys.org/news/2020-10-scientists-encapsulate-quantum-dots-salt.html Nanomaterials Mon, 19 Oct 2020 09:21:59 EDT news522318112 Magnetoresistive random access memory (MRAM) is the top candidate for next-generation digital technology. However, manipulating MRAM efficiently and effectively is challenging. An interdisciplinary research team based at National Tsing Hua University (NTHU) in Taiwan, led by Prof. Chih-Huang Lai, Department of Materials Science and Engineering, and Prof. Hsiu-Hau Lin, Department of Physics has now achieved a breakthrough. By adding a layer of platinum only a few nanometers thick, their device generates spin current to switch the pinned magnetic moments at will—a task that has never been accomplished before. For faster reading and writing, reduced power consumption and retaining data through a power outage, MRAM is particularly promising. https://phys.org/news/2020-09-scientists-magnetoresistive-ram.html Nanomaterials Thu, 24 Sep 2020 07:40:19 EDT news520152013
