How to make a better water filter? Turn it inside out
Penn engineers describe a novel approach for making antimicrobial nanoscale water filters while demonstrating new approaches that can be used to develop a broad range of materials.

When wet, the material conforms to the grooves on a surface, and when dry, the material hardens and fastens itself securely to the surface.
Penn Engineers’ self-healing liquid metal electrode extends life of Li-ion battery alternative
Penn Engineers’ self-healing liquid metal electrode extends life of Li-ion battery alternative
In the researchers’ new anode design, gallium repeatedly melts and solidifies, “healing” the cracks that would otherwise gradually decrease the battery’s ability to hold a charge.

Reversible superglue proves strong enough to hold average man
Shu Yang and colleagues from the School of Engineering and Applied Science have developed a new glue from hydrogel, inspired by snail slime. “The mucus [snails] produce is a viscous liquid, but when it dries they become firmly stuck,” said Yang.
