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 ...

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 ...

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 ...

Viruses can spread not only via droplets or aerosols like the new coronavirus, but in water, too. In fact, some potentially dangerous pathogens of gastrointestinal diseases are water-borne viruses. To ...

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 ...

Scientists in Australia have developed new ultra-thin filters that can separate valuable chemicals from liquid mixtures fast and efficiently to make medicines, dyes and other products, which could ...
