Researchers at TU Wien have designed a nano-structuring method, with which certain layers of a material can be perforated with extreme precision while others are left completely untouched, even though the projectile penetrates all layers.

This is made possible with the help of highly charged ions - they can be used to selectively process the surfaces of novel 2D material systems, for example to anchor certain metals on them, which can then serve as catalysts.

Versarien has announced the launch of its first graphene-enhanced protective face mask, which utilizes Polygrene, Versarien’s graphene-enhanced polymer.

The launch of the new protective face mask is said to coincide with the first two orders Versarien has received following recent prelaunch sales activity, which resulted in 100,000 masks being delivered to a leading British university and 20,000 ordered by a UK electrical and mechanical servicing and repairs business.

In May, First Graphene announced it is collaborating with Hexcyl to develop PureGRAPH-enhanced HDPE materials for use in Hexcyl’s range of oyster baskets and long-line farming systems. Now, First Graphene updated on successful trial results from the application of PureGRAPH graphene to these oyster baskets with the South Australian shellfish aquaculture manufacturer Hexcyl Systems.

Using FGR’s PureGRAPH products, the High-Density Polyethylene (HDPE) reportedly showed improvements in strength, wear resistance and longevity.
