Winds spread PFAS pollution far from a manufacturing facility

Concerns about environmental and health risks of some fluorinated carbon compounds used to make non-stick coatings and fire-fighting foams have prompted manufacturers to develop substitutes, but these replacements are increasingly ...

Polymer membranes could benefit from taking a dip

Many industrial processes rely on thin membranes that can clean water, for example, by filtering out impurities. In recent years, a technique called atomic layer deposition (ALD) has been used to tune these membranes for ...

POCKET DNA-testing kit uses smartphone to detect mutations

A team of researchers affiliated with several institutions in China and one in the U.S. has developed the POCKET DNA-testing kit—a small, inexpensive system that uses a 3-D-printed integrated chip and a smartphone to perform ...

A possible end to 'forever' chemicals

Synthetic chemicals known as per- and polyfluoroalkyls, or PFAS, contain bonds between carbon and fluorine atoms considered the strongest in organic chemistry. Unfortunately, the widespread use of these nonbiodegradable products ...
