Sentences with phrase «graphene oxide membranes»

The graphene oxide membranes allow high water flow at atmospheric pressure, while removing virtually all of the organic matter.

Dr Joshi said: «The new treatment system is made by converting naturally occurring graphite into graphene oxide membranes that allow high water flow at atmospheric pressure, while removing virtually all of the organic matter.»

Not exact matches

A few years ago, his lab made graphene oxide — a functional form of graphene — and fabricated it into a multilayer, micrometer - thick, paper - like membrane.

This allows the tiny capillaries of the graphene - oxide membranes to block the salt from flowing along with the water.

Previously graphene - oxide membranes have shown exciting potential for gas separation and water filtration.

Graphene - oxide membranes have attracted considerable attention as promising candidates for new filtration technologies.

Previous research at The University of Manchester found that if immersed in water, graphene - oxide membranes become slightly swollen and smaller salts flow through the membrane along with water, but larger ions or molecules are blocked.

It is hoped that graphene - oxide membrane systems can be built on smaller scales making this technology accessible to countries which do not have the financial infrastructure to fund large plants without compromising the yield of fresh water produced.

Using metal ions with three or more positive charges, researchers in Tian's laboratory bonded graphene - oxide flakes into a transparent membrane.

Researchers at the University of Manchester have developed a graphene - oxide membrane with a scalable, uniform pore size that can filter out even the smallest salts, giving it potential for producing drinking water from salt water without affecting the flow of the water too much.

Adapting an existing in - house technology, a graphene oxide solution is poured onto a wax - printed paper membrane.

This membrane acts as a kind of mould which, when wetted briefly in water and then hand - shaken (yes, hand - shaken) from side to side in ethanol, sets and releases multiple self - rolled graphene oxide tubes — the basic building block of our micromotors.
