Rice team transforms waste into graphene in a flash

A team of researchers at the Rice University lab of chemist James Tour has designed a ‘Green’ process that produces pristine graphene in bulk using waste food, plastic and other materials. According to the team, this process can help facilitate a reduction of the environmental impact of concrete and other building materials.

The new process can turn bulk quantities of just about any carbon source into graphene flakes. The process is quick and cheap; Tour said the “flash graphene” technique can convert a ton of coal, food waste or plastic into graphene for a fraction of the cost used by other bulk graphene-producing methods.

Graphene Flagship partners develop a graphene-titania photocatalyst that gets rid of NOx pollutants

Graphene Flagship partners the University of Bologna, Politecnico di Milano, CNR, NEST, Italcementi HeidelbergCement Group, the Israel Institute of Technology, Eindhoven University of Technology, and the University of Cambridge have developed a graphene-titania photocatalyst that degrades up to 70% more atmospheric nitrogen oxides (NOx) than standard titania nanoparticles in tests on real pollutants.

To address the problem of atmospheric pollution, researchers worldwide are on the hunt for new ways to remove pollutants from the atmosphere, and photocatalysts such as titania are a good way to do this. When titania is exposed to sunlight, it degrades nitrogen oxides – which are very harmful to human health – and volatile organic compounds present at the surface, oxidizing them into inert or harmless products.

Skanska on its way to trial graphene-enhanced asphalt on the M25

Earlier this month, it was reported that Directa Plus and Skanska are getting ready a trial of re-surfacing a section of a UK road in Curbridge, Oxfordshire with materials containing G+ graphene substance. Now, Skanska has mentioned that it is also in talks to trial the graphene-enhanced asphalt on the UK's M25.

The Curbridge works, which were delivered by subcontractor Aggregate Industries, involved removal and reinstatement of the existing carriageway to a depth of 150mm over a 750m-long section. One lane was replaced using conventional materials, while the opposite ‘trial’ lane was resurfaced using the asphalt enhanced by the innovative asphalt modifier.

GrapheneCA provides graphene for major commercial construction project in Mexico

GrapheneCA has reported that it is the sole provider for all of the graphene being used in a major commercial construction project that makes use of the miracle material currently underway in Mexico.
