Ultra-sensitive, solar-blind photodectors for harsh environments
As a crucial part of spectrum analysis, solar-blind ultraviolet photodetectors (SBPDs) are applied to many fields. Because of their specialized applications, they have to cope with harsh environments such as overabundant temperature and radiation. Th.....»»
Quantum physics in proteins: AI affords unprecedented insights into how biomolecules work
A new analytical technique is able to provide hitherto unattainable insights into the extremely rapid dynamics of biomolecules. The team of developers, led by Abbas Ourmazd from the University of Wisconsin–Milwaukee and Robin Santra from DESY, is p.....»»
Argon Fluoride Laser Could Lead To Practical Fusion Reactors
The US Naval Research Laboratory (AFL) is developing an Argon Fluoride (ArF) laser that may one day make fusion power a practical commercial technology. New Atlas reports: The wide-bandwidth ultraviolet laser is designed to have the shortest laser wa.....»»
Holey metalens! New metalens focuses light with ultra-deep holes
Metasurfaces are nanoscale structures that interact with light. Today, most metasurfaces use monolith-like nanopillars to focus, shape and control light. The taller the nanopillar, the more time it takes for light to pass through the nanostructure, g.....»»
