With new, more contagious strains of the coronavirus spreading in the U.S., and transmission levels still very high in many places, some public health experts recommend that Americans upgrade from the basic cloth masks that many have been wearing during the pandemic. “A cloth mask might be 50% effective at blocking viruses and aerosols,” says Linsey Marr, a researcher at Virginia Tech who studies airborne virus transmission. “We’re at the point now … that we ne...

It's time to up your mask game. With new, more contagious strains of the coronavirus spreading in the U.S., and transmission levels still very high in many places, some public health experts recommend that Americans upgrade from the basic cloth masks that many have been wearing during the pandemic.

Now, researchers reporting in ACS' Nano Letters have made a prototype of an anode-free, zinc-based battery that uses low-cost, naturally abundant materials. Aqueous zinc-based batteries have been previously explored for grid-scale energy storage because of their saf...
