Industrially manufactured multi-layered large-scale sheet graphene samples have been received by the International Space Elevator Consortium (ISEC)

In the last entry, I mentioned that a graphene manufacturer had been in touch. That manufacturer was General Graphene, based in Knoxville Tennessee, USA. Right now, General Graphene is one of only two companies in the world that has demonstrated the ability to manufacture polycrystalline sheet graphene at industrial scale, separate the graphene and layer …

What would a space elevator tether made from 2D materials look like? – Part Two: A tale of two tethers

In the previous post, I made a prediction that a Space Elevator tether created from multi-layered single crystal graphene would look metallic and probably mirror-like.  A graphene manufacturer has been in touch. They are one of the few companies in the world that can make polycrystalline sheet graphene and layer it up. They told me …

What would a space elevator tether made from 2D materials look like?

At the time of writing there are three potential materials that are light enough and strong enough to make the tether for the space elevator. Carbon nanotubes, Graphene and hexagonal Boron Nitride. So, to answer the question posed at the start, a space elevator tether would look like a glittering sliver mirror ascending into the …

Graphene dough and graphenic glass

We are finding out how useful graphene and graphene oxide powders can be.  Right now in 2019 graphene is being used to make quieter cars, ‘greener’ concrete and stronger industrial plastics. The graphene in these products is nanoplate graphene made from graphite.  Manufacturing companies understand how to make graphene as powders and dispersions. However, handling these …

Latest data shows astonishing rate of progress in the field of graphene

Our work editing the Nixene Journal means we keep track of developments in the world of graphene every month.  Compiling and curating the articles provides a viewpoint that a small number of us share.  We are publishing volume three this year and when I stop to reflect, I am amazed at the pace of developments …

Electric current controls water flow through graphene oxide membranes

An international team led by Manchester University, UK has discovered a fascinating property of graphene oxide membranes. (one micron thick membrane made from graphene oxide (GO) with a flake size of approximately 10 μm).  They found that water would pass through the membrane.  However when they applied an electric current across the membrane the water flow …

Extraordinary water adsorption characteristics of graphene oxide

This is a combined effort of researchers from Australia India and Japan. The paper is available at this link. They looked at the way graphene oxide nanoplates (GO) interacted with water vapour. They observed that GO imparts a very high water uptake capacity up to 0.58 gram of water per gram of GO (g g-1) …
