Nanoparticle-coated sponge removes lead from water

May 11, 2023 (Nanowerk News) Northwestern University engineers have developed a new sponge that can remove metals — including toxic heavy metals like lead and critical metals like cobalt — from contaminated water, leaving safe, drinkable water behind. In proof-of-concept experiments, the researchers tested their new sponge on a highly...

Researchers find new approach to explore earliest universe dynamics with gravitational waves

May 11, 2023 (Nanowerk News) Researchers have discovered a new generic production mechanism of gravitational waves generated by a phenomenon known as oscillons, which can originate in many cosmological theories from the fragmentation into solitonic “lumps” of the inflaton field that drove the early Universe’s rapid expansion, reports a new...
