Oxygen groups key to unlocking graphene’s antimicrobial potential
Mar 08, 2023 (Nanowerk News) The amount of surface oxygen in graphene materials is a key factor in how effective they could be in killing bacteria – a discovery which may help to design safer and more effective products to combat antimicrobial resistance. Graphene oxide with high surface oxygen content...
how the future might influence the past
Mar 08, 2023 (Nanowerk News) In 2022, the Physics Nobel prize was awarded for experimental work showing that the quantum world must break some of our fundamental intuitions about how the universe works. Many look at those experiments and conclude that they challenge “locality” — the intuition that distant objects...
New kind of transistor could shrink communications devices on smartphones
Mar 08, 2023 (Nanowerk News) One month after announcing a ferroelectric semiconductor at the nanoscale thinness required for modern computing components, a team at the University of Michigan has demonstrated a reconfigurable transistor using that material. The study is a featured article in Applied Physics Letters ("Fully epitaxial, monolithic ScAlN/AlGaN/GaN...
Novel memristors are based on perovskite nanocrystals
Mar 08, 2023 (Nanowerk News) In many respects, the human brain is still superior to modern computers. Although most people can't do math as fast as a computer, we can effortlessly process complex sensory information and learn from experiences, while a computer cannot – at least not yet. And, the...
Super-resolution in ultrafast scattering
Mar 08, 2023 (Nanowerk Spotlight) The Nobel Prize in Chemistry in 2014 was a recognition of the groundbreaking advancements made in the field of super-resolved fluorescence microscopy. The prestigious award was jointly presented to Eric Betzig, Stefan Hell, and William Moerner for their contributions to surpassing the physical limitations of...
Biomolecular sliding at the nanoscale
Mar 06, 2023 (Nanowerk News) Researchers at Kanazawa University report in Nano Letters ("High-Speed Atomic Force Microscopy Reveals Spontaneous Nucleosome Sliding of H2A.Z at the Subsecond Time Scale") the discovery of a biomolecular dynamical process likely relevant to gene expression. The process, revealed by means of high-speed atomic force microscopy,...
Controlling electric double layer dynamics for next generation all-solid-state batteries
Mar 06, 2023 (Nanowerk News) In our quest for clean energy and carbon neutrality, all-solid-state lithium-ion batteries (ASS-LIBs) offer considerable promise. ASS-LIBs are expected to be used in a wide range of applications including electric vehicles (EVs). However, commercial application of these batteries is currently facing a bottleneck—their output is...
