Rensselaer Polytechnic Institute researchers have developed an accessible way to make N95 face masks not only effective barriers to germs, but on-contact germ killers. The antiviral, antibacterial masks can potentially be worn longer, causing less plastic waste as the masks do not need to be replaced as frequently.

Humpty Dumpty, the famous egg of nursery rhyme fame, fell off a wall and couldn’t be put back together again. But if he’d worn a protective jacket made of gelatin and cornstarch, he could have stayed intact. Researchers in ACS Applied Materials & Interfaces report that by adding starch to gelatin, they have created gels…

For decades, field-effect transistors enabled by silicon-based semiconductors have powered the electronics revolution. But in recent years, manufacturers have come up against hard physical limits to further size reductions and efficiency gains of silicon chips. That has scientists and engineers looking for alternatives to conventional metal-oxide semiconductor (CMOS) transistors.
