UK-China collaboration will develop graphene standards

Nov 19, 2017

The first UK-China Graphene Standardization Cooperation Working Group Conference, recently held in Chongqing, China, brought news of an agreement to collaborate on developing and submitting a co-authored International Organization for Standardization (ISO) proposal by February 2018. This joins other recent graphene standardization efforts, like NPL & NGI's good practice guide for graphene metrology and NPL's first ISO (International Organization for Standardization) graphene standard.

Research institutes across the world are pursuing the commercialization of graphene. However, the lack of well-established international standards could slow down the speed of adoption, lead to costly duplication and competition that hinders trade. This collaboration on graphene standards will aim to reduce technical barriers to trade and joint R&D in an area that is a strength for both countries with huge market potential.

Graphene-based structures found to have extremely long spin relaxation lifetime

Nov 18, 2017

Researchers from Spain's ICN2 institute have discovered that graphene/TMDC heterostructures can exhibit etremely long spin relaxation lifetime. These structure feature lifetimes that are orders of magnitude larger than anything observed in 2D materials - and in fact these results point to a qualitatively new regime of spin relaxation.

Spin relaxation lifetime means that time it takes for the spin of electrons in a spin current to lose their spin (return to the natural random disordered state). A long lifetime is very important for spintronics devices. This new study reveals that the rate at which spins relax in graphene/TMDC systems depends strongly on whether they are pointing in or out of the graphene plane, with out-of-plane spins lasting tens or hundreds of times longer than in-plane spins.

NanoXplore and Martinrea to co-develop graphene-enhanced automotive products

Nov 16, 2017

NanoXplore recently reported that Martinrea International has made an investment in the Company and has become a shareholder of NanoXplore following participation in the equity financing which closed on August 2nd, 2017. Both companies have been working on product development since.

Martinrea produces parts and assemblies, modules, fluid-management systems and offers lightweighting solutions, primarily for the automotive sector.

Manchester team creates graphene oxide membranes that can filter organic solvents

Nov 15, 2017

Researchers at the National Graphene Institute and School of Chemical Engineering and Analytical Science at The University of Manchester have developed an ultra-thin membrane using graphene-oxide sheets, that were assembled in a way that they were able to completely remove various organic dyes, dissolved in methanol, which were as small as a nanometre. This is exciting as GO membranes were once thought to be permeable only to aqueous solutions, but the researchers developed a new form of graphene oxide membrane that can filter organic solvents.

In the newly developed ultrathin membranes, graphene-oxide sheets are assembled in such a way that pinholes formed during the assembly are interconnected by graphene nanochannels, which produces an atomic-scale sieve allowing the large flow of solvents through the membrane. When used to filter Cognac and whisky, the membrane permitted alcohol to pass through but trapped the larger molecules that gives the whisky its color. Professor Nair, which led the group, said that "the clear whisky smells similar to the original whisky but we are not allowed to drink it in the lab, however it was a funny Friday night experiment!”

Low-cost batteries could be made from graphene, waste graphite and scrap metal

Nov 14, 2017

Researchers from Empa and ETH Zürich have used graphene, waste graphite and scrap metal to make low-cost batteries.

The researchers’ ambitious goal at Empa is to make a battery out of the most common elements in the Earth’s crust – such as magnesium or aluminum. These metals offer a high degree of safety, even if the anode is made of pure metal. This also offers the opportunity to assemble the batteries in a very simple and inexpensive way and to rapidly upscale the production. To make such batteries work, the liquid electrolyte needs to consist of special ions that do not crystallize at room temperature. The researchers were looking for a suitable cathode material, and decided to turn the principle of the lithium ion battery upside down.

Despite initial reports, MIT-Lamborghini supercapacitor to be based on MOFs and not graphene

Nov 14, 2017

A few days ago, the collaboration between MIT and Lamborghini to develop a graphene-enhanced supercar was talked about all over, and caused great excitement. However, the Graphene-Info team was not satisfied with the scarcity of the details supplied, and approached MIT Professor Mircea Dinca, the spearheads this project.

Prof. Dinca stated that the supercapacitors that are bring developed as part of this collaboration most decidedly do not have graphene in them and are not graphene-enhanced. "In fact, the whole point is that we are not using graphitic materials, which is what most other EDLCs use. Instead, we are using materials known as metal-organic frameworks, some of which have graphene-like (i.e. 2D) structures, but are definitely not made of graphene", Dinca said.

CVD Graphene prices continue to drop as commercial applications start to enter the market

Nov 13, 2017

CVD processes are used to create high-quality single layer (also bi-layer and tri-layer) graphene sheets. These kinds of sheets exhibit exceptional properties and can be used in a variety of exciting applications, from touch layers to transistors and sensors. For many years, CVD has been a high cost production process and this graphene is still mostly used in research projects in academic and research institutes, but prices are gradually dropping, to the point where commercial applications are starting to appear on the market.

Graphenea Monolayer CVD prices (2015-2017)

Recent years have, as we said, brought on a continuing price drop in CVD graphene prices. Spain-based Graphenea, a global CVD graphene leader, has an online shop in which it offers its high-end CVD graphene samples. We have been tracking the prices of Graphenea's CVD graphene since late 2015, and the graph above shows the price decrease.
