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.

In a statement, the privately-owned graphene supplier and manufacturer, said the new convention center, Centro de Convenciones Siglo XXI, which is being built 200 kilometers away from Cancún, relies on concrete enhanced by GrapheneCA’s 99.7% carbon pure graphene in its entirety.

GrapheneCA launches graphene-based admix for cement improvement

Grapheneca logoGrapheneCA recently introduced a new product line called Original Graphene (OG). OG Concrete Admix, aimed at the retail concrete industry, reportedly imbues cement with graphene’s superior properties to make it stronger, lighter, and more resistant.

GrapheneCA’s focus on a price-sensitive application is said to lead to taller, faster, lighter, and more durable constructions overall, with the added benefit of being eco-friendly. The launch of Original Graphene Cement admix targets multiple improvements in cement from a single additive reducing cracking, improving strength and weather resistance to build structures that last.

Aecom uses graphene by Versarien to 3D print an arch that may modernize transport networks

Global infrastructure services firm Aecom is reportedly developing one of the UK’s first 3D-printed commercial products made from graphene-reinforced polymer.

Aecom has produced a graphene arch using additive manufacturing techniques. It believes the method could reduce the time and cost of installing digital signalling systems and transform the digitization of transport networks. The 4.5-meter high, lightweight arch is being tested on outdoor track at Network Rail’s workforce development center in Bristol.
