has developed a type of sponge made of graphene oxide and chitosan, that can be used to extract gold from electronic waste.

Discarded electronics, known as e-waste, often contain large amounts of gold and other heavy metals. Scientists have come up ...

The new development could go a long way in making batteries that are more affordable, charge faster, and last longer.

An international research group has unveiled a heterojunction solar cell based on graphene-oxide (GO) and silicon with a large area of 5.5 cm 2. GO is a compound of carbon, oxygen and hydrogen ...

Sounds pretty amazing to us. Lead researcher, Ali Reza Ranjbartoreh, claims that: The exceptional mechanical properties of synthesized graphene paper render it a promising material for commercial ...

Graphene is the ideal material for blocking the release of oxygen into the electrolyte. Researchers demonstrated that if they wrapped very small particles of the lithium cobalt oxide cathode of a ...

Now, researchers convert straw and other cellulosic waste biomass into reduced graphene oxide, a valuable and prized nanomaterial, through a simple reaction. Diluting phosphorescent and thermally ...
