Abdellahi Sow uses the VENUS apparatus, which offers researchers insight into how life can form in space. Credit: Emanuele Congiu Called VENUS, the device will…
Even though common mask materials block most of the droplets that spread the virus, that may not be enough at close distances. Simply wearing a…
The cough-generated droplets from a walking individual disperse differently in a narrow corridor and an open space. In narrow corridors, the droplets are concentrated in…
By copying the multilayer geometry of mammal bones, cathodes for sodium-ion batteries can be made more structurally stable, while maintaining high capacities and fast charge…
Face shields worn alone are not effective against COVID-19 sneezes. Do face shields provide enough protection to the wearers against COVID-19 if they don’t also…
In the Journal of Vacuum Science and Technology A, researchers investigate the origins of degradation in high energy density LIB cathode materials and develop strategies…
Forecasting cannot foresee COVID-19 infection rates peaking or plateauing. During the first months of the COVID-19 pandemic, Joseph Lee McCauley, a physics professor at the…
Face masks slow spread of COVID-19; types of masks, length of use matter. The use of face masks to help slow the spread of COVID-19…
