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 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 ...

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 ...

Scientists from Nanyang Technological University, Singapore (NTU Singapore), in collaboration with ETH Zurich, Switzerland (ETHZ), have created a membrane made from a waste by-product of vegetable oil ...

Protein-based membranes can cope with water fluxes much higher than those that can be handled by commercial membranes with similar rejection properties. Membrane interfaces are unsung heroes of the ...

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 ...

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 ...

Seawater is a complex cocktail of useful minerals, but it's hard to separate out the specific ones we need. Now, a team of scientists from Australia and the US has developed a new water desalination ...

Dialysis, in the most general sense, is the process by which molecules filter out of one solution, by diffusing through a membrane, into a more dilute solution. Outside of hemodialysis, which removes ...
