Sentences with phrase «on graphene oxide»

However, the wallpaper's real smarts are down to an ink - based on graphene oxide.

By 3D printing the bacteria in precise patterns on the graphene oxide, they hope to carve lines of conductivity, like tiny wires, on an otherwise non-conductive surface.

Dr Joshi has an international reputation in this area, having published many highly cited articles including one in the journal Science on graphene oxide - based filtration in 2014 while working at the University of Manchester with Nobel Laureate Sir Andre Geim.

Not exact matches

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.

Researchers at Umeå University, together with researchers at Uppsala University and Stockholm University, show in a new study how nitrogen doped graphene can be rolled into perfect Archimedean nano scrolls by adhering magnetic iron oxide nanoparticles on the surface of the graphene sheets.

They showed that the lithium ions form a thin film on the surface of the graphene oxide and then diffuse through defect sites — essentially gaps in the layers of the material — before settling below the bottom layer of the graphene oxide.
