Versarien updates on AECOM collaboration

Versarien LogoVersarien, the advanced materials engineering group, has announced that it has signed a supply agreement to provide Versarien's new graphene enhanced polymer range to AECOM for a current infrastructure project.

This supply agreement follows the collaboration Versarien entered into with AECOM, a US headquartered and Fortune 500 company. This collaboration covered a project that AECOM and Versarien have been undertaking involving the incorporation of Versarien's graphene nano-platelets into large scale polymer structures used in civil infrastructure projects, with a view to increasing their structural strength.

Versarien receives graphene order for fire retardant aircraft interior parts

Versarien LogoVersarien has announced that it has received an order for the supply of Versarien's graphene nano platelets to a design and manufacturing company for use in fire retardant aircraft interior parts for a major global airline.

The order is for an initial 1 kg of the Company's graphene nano platelets and it is anticipated that further orders will be received to fulfill the end-customers' contract. The specific aircraft interior parts have reportedly gained the necessary certification from a USA-based, Federal Aviation Administration (FAA) certified, fire testing laboratory.

Bionic mushroom interacts with bacteria and graphene to generate electricity

In a recent study, researchers from the Stevens Institute of Technology in the U.S have come up with an original idea - they designed a bionic mushroom that uses graphene to produce electricity. More accurately, the researchers have generated mushrooms patterned with energy-producing bacteria and an electrode network.

Many examples of organisms that live closely together and interact with each other exist in nature. In some cases, this symbiotic relationship is mutually beneficial. The research team wanted to engineer an artificial symbiosis between button mushrooms and cyanobacteria. In their vision, the mushroom would provide shelter, moisture and nutrients, while bacteria 3D-printed on the mushroom's cap would supply energy by photosynthesis. Graphene nanoribbons printed alongside the bacteria could capture electrons released by the microbes during photosynthesis, producing bio-electricity.

Research team examines graphene's effects on the lungs

Researchers from Empa and the Adolphe Merkle Institute (AMI) in Fribourg have conducted studies on a 3D lung model to examine the behavior of graphene and graphene-like materials once they have been inhaled.

Thanks to the 3-D lung model, the researchers have succeeded in simulating the actual conditions at the blood-air barrier and the impact of graphene on the lung tissue as realistically as possible – without any tests on animals or humans. It is a cell model representing the lung alveoli. Conventional in vitro tests work with cell cultures from just one cell type – the newly established lung model, on the other hand, bears three different cell types, which simulate the conditions inside the lung, namely alveolar epithelial cells and two kinds of immune cells – macrophages and dendritic cells.
