Freezing lithium batteries may make them safer and bendable

Yuan Yang, assistant professor of materials science and engineering at Columbia Engineering, has developed a new method that could lead to lithium batteries that are safer, have longer battery life, and are bendable, providing ...

It takes more than peer pressure to make large microgels fit in

When an assembly of microgel particles includes one particle that's significantly larger than the rest, that oversized particle spontaneously shrinks to match the size of its smaller neighbors. This self-healing nature of ...

Faster, finer filtration

The right blend of polymers enables rapid and molecule-selective filtering of tiny particles from water.

Soft core, hard shell – the latest in nanotechnology

Nanoparticles are the smallest particles capable of reaching virtually all parts of the body. Researchers use various approaches to test ways in which nanoparticles could be used in medicine – for instance, to deliver substances ...

The new superstrong

In today's market for high performance fibers, used for applications such as bulletproof vests, manufacturers have only four options: Kevlar, Spectra, Dyneema, and Zylon. Made from polymers such as polyethylene, these were ...
