A functional dialysis membrane has been fabricated from a sheet of graphene -- a single layer of carbon atoms, linked end to end in hexagonal configuration like that of chicken wire. The graphene ...

A team of Korean researchers have made a membrane that can turn saltwater into freshwater in minutes. The membrane rejected 99.99% of salt over the course of one month of use, providing a promising ...

Scientists have known for years that membranes can do things such as act as a filter for saltwater. When salty ocean water is moved through a membrane, clean water comes out the other side that can be ...

The antimicrobial triclosan is widely used in personal hygiene products, textiles and plastics, but when it enters the environment via wastewater, it poses a significant threat to aquatic organisms.

Filtering water is an incredibly important process, but it's not as simple as it seems. As the pores in a membrane inevitably get clogged with material, it takes time and energy to clean or replace ...

A "straight out of science fiction" liquid membrane developed by a team of Penn State mechanical engineers acts as a "reverse filter" that lets large objects through while blocking small ones. The ...

The process of desalination, the filtering of salt from salt water, is surprisingly complicated. Removing impurities from water to leave a drinkable product at the end is often performed at dedicated ...

As reported by Smithsonian Magazine, Heller's interest in water treatment began close to home in Warrington, Virginia, after ...
