Waste plastic converted into filtration membranes

In a world that seems to be drowning in plastic bottles, recycling this waste into useful materials would help to reduce its environmental impact. KAUST researchers have now invented a way to turn plastic bottles into porous ...

Water desalination picks up the pace

A membrane made of porous carbon-fiber structures grown on a porous ceramic substrate is more efficient at filtering seawater than existing similar membranes.

More realistic and accurate organs-on-chips

In a step toward better diagnosis and treatment of digestive conditions, such as inflammatory bowel disease, scientists report in ACS Biomaterials & Engineering that they have developed a first-of-its-kind collagen-based ...

Scientists produce dialysis membrane made from graphene

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 waste from blood, scientists ...

Plant cellulose prevents short circuits in batteries

(Phys.org)—In order to prevent short circuits in batteries, porous separator membranes are often placed between a battery's electrodes. There is typically a tradeoff involved, since these separators must simultaneously ...

Faster, finer filtration

The right blend of polymers enables rapid and molecule-selective filtering of tiny particles from water.
