UV lamps used for disinfection may impair indoor air quality

Using ultraviolet germicidal radiation (UVGI) to disinfect indoor spaces is a demonstrably effective way of deactivating various pathogens (including the SARS-CoV-2 coronavirus). It deactivates bacteria and viruses by exposing ...

A new way to identify stresses in complex fluids

Fluid dynamics researchers use many techniques to study turbulent flows like ocean currents, or the swirling atmosphere of other planets. Arezoo Adrekani's team has discovered that a mathematical construct used in these fields ...

Mie voids could bring about control of light in air

Resonant optical phenomena in metals and dielectrics have profound applications in many fields. The nanoscale confinement allows for unpreceded control of light-matter interaction at surfaces and interfaces, manipulating ...
