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 ...

Throughout her career, Ayse Asatekin, associate professor of chemical and biological engineering at Tufts University, has sought to use filters to prevent illness and protect the environment. One ...

Engineers have created a bacteria-filtering membrane using graphene oxide and bacterial nanocellulose. It's highly efficient, long-lasting and environmentally friendly -- and could provide clean water ...

As governments around the world struggle to build up a supply of N95 masks for healthcare workers—navigating price gouging, counterfeit respirators, scammers, and fierce competition from other ...

A team of Australian and US scientists has made a breakthrough in the development of membranes that, paradoxically, allow large molecules through far more readily than smaller ones. The new ...

Filtering the salt from seawater can take a lot of energy or specialised engineering. A thin membrane made of porous wood may be able to fix that. In membrane distillation, salty water is pumped ...

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 ...
