Scientists evaluate different antimicrobial metals for use in water filters
Porous ceramic water filters are often coated with colloidal silver, which prevents the growth of microbes trapped in the micro- and nano-scale pores of the filter. Other metals such as copper and zinc have also been shown ...

Billard game in an atom: Physicists trace the double ionization of argon atoms on attosecond time scales
(Phys.org) -- When an intense laser pulse interacts with an atom it generates agitation on the micro scale. A rather likely outcome of this interaction is single ionization, where one electron is ejected from ...
