Ultrathin graphene oxide-based hollow fiber membranes with brush-like CO2-philic agent for highly efficient CO2 capture

Among the current CO2 capture technologies, membrane gas separation has many inherent advantages over other conventional techniques. However, fabricating gas separation membranes with both high CO2 permeance and high CO2/N2 selectivity, especially under wet conditions, is a challenge. In this study, sub-20-nm thick, layered graphene oxide (GO)-based hollow fiber membranes with grafted, brush-like CO2-philic agent alternating between GO layers are prepared by a facile coating process for highly efficient CO2/N2 separation under wet conditions.

10 graphene-enhanced products already on the market

Graphene has been attracting attention due to its exciting properties and countless ideas for applications benefiting from those properties have been thought of; However, it is rightfully claimed that graphene has yet to transform an actual industry or become a household name.

With that said, graphene seems to be slowly but surely entering the market in all sorts of products. In this post, we list 10 products already commercially available that contain graphene – and these are not all of them. Hopefully this is just the beginning and many more applications will follow.

Magnetism in graphene can be controlled with hydrogen atoms

Graphene has extraordinary mechanical and electronic properties, but no magnetic properties. This can be made up for with the help of the lightest element: hydrogen, which transfers its magnetic moment on coming into contact with graphene. This has been demonstrated by a team of European scientists coordinated by the physicist Iván Brihuega from the Autonomous University of Madrid.

Longest Graphene Nanoribbon

The properties of graphene nanoribbons depend on structural variables such as width, length, edge structure, and heteroatom-doping. Therefore, atomic precision over all these variables is necessary for establishing their fundamental properties and exploring their potential applications.
