The University of Manchester has teamed up with British sportswear brand Inov-8 to become the world's first company to incorporate graphene into running and fitness shoes. Laboratory tests have shown that the rubber outsoles of the newly developed shoes, planned to arrive on the market in 2018, are stronger, more stretchy and more resistant to wear.

Michael Price, inov-8 Product and Marketing Director, said: “Off-road runners and fitness athletes live at the sporting extreme and need the stickiest outsole grip possible to optimize their performance, be that when running on wet trails or working out in sweaty gyms. For too long, they have had to compromise this need for grip with the knowledge that such rubber wears down quickly... Now, utilizing the groundbreaking properties of graphene, there is no compromise. The new rubber we have developed with the National Graphene Institute at The University of Manchester allows us to smash the limits of grip. Our lightweight G-Series shoes deliver a combination of traction, stretch and durability never seen before in sports footwear. 2018 will be the year of the world’s toughest grip.”

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!”
