Researchers achieve unprecedented control of polymer grids

Synthetic polymers are ubiquitous—nylon, polyester, Teflon and epoxy, to name just a few—and these polymers are all long, linear structures that tangle into imprecise structures. Chemists have long dreamed of making polymers ...

Simultaneous synthesis and fixing of covalent organic frameworks

Covalent organic frameworks (COFs) are versatile materials composed of interconnected organic molecules held together by covalent bonds. These frameworks can be constructed in two-dimensional or three-dimensional (3D) forms ...

Absorbent aerogels show some muscle

A simple chemical process developed at Rice University creates light and highly absorbent aerogels that can take a beating.
