Versarien launches graphene-enhanced protective face masks

Versarien LogoVersarien 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.

First Graphene announces successful trials with HDPE for oceanic farming

First Graphene logo imageIn 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.

Zen Graphene Solutions moves forward with applying its virucidal graphene ink in PPE applications

Zen Graphene Solutions logo imageZEN Graphene Solutions has announced it has commenced collaborations with research teams at a number of personal protective equipment (PPE) manufacturers to incorporate ZEN’s virucidal graphene ink into commercial products, including masks, gloves, gowns and other clothing following Zen’s promising results for an antiviral, graphene-based ink formulation from The University of Western Ontario’s ImPaKT Facility, biosafety Level 3 lab.

The company continues to optimize its proprietary formulation for dosage and delivery mechanism for highest antiviral impact. The next phase of testing is currently underway at the ImPaKT Facility and includes a preferred mask fabric coated in ZEN’s virucidal ink exposed to and tested against the COVID-19 virus.

First Graphene collaborates with the University of Warwick on graphene-enhanced thermoplastics

First Graphene logo imageFirst Graphene has announced a collaboration with the University of Warwick on a project to unlock the potential of graphene in thermoplastic systems.

First Graphene has secured an award under the Warwick Collaborative Post Graduate Research Scholarship Scheme, in conjunction with the Warwick Manufacturing Group (WMG). WMG has established a successful model for collaboration between academia and the private and public sectors and has very strong links with world-leading industrial partners such as Jaguar Land Rover, who have located their advanced research group at the WMG campus.

Mapping crystal shapes could fast-track mass production of 2D materials

Researchers come up with a promising new design for graphene-enhanced fuel cells

Researchers at University College London, Queen Mary University of London and Humboldt Universität zu Berlin have suggested a design for a hydrogen fuel cell, with graphene as a key component. The new research promises to address some of the roadblocks that have thus far hindered the development of this clean, non-toxic, renewable technology, thus opening up hydrogen fuel cells as a potential clean-energy breakthrough.

At the moment the US Department of Energy estimates that the cost of energy generated by hydrogen fuel cells is around $61 per kilowatt. The ultimate aim is to get this down to $30 per kilowatt. The scaling up in the production of graphene-coated nanoparticles suggested in the paper could help significantly in this quest. The team’s findings could also extend beyond the field of fuel cells, lending itself to some exciting technological applications.

New graphene-based memory device could extend smartphone battery life and increase data upload speed

Researchers at the USC Viterbi School of Engineering have created a graphene-based memory device which promises to increase data upload speed, extend smartphone battery life, and reduce data corruption. The team did this through a concept called the ferroelectric tunneling junction (FTJ).

This new memory device is part of a family known as non-volatile memory devices, meaning they can be unplugged and still retain their data, much like cell phone memory and USB flash drives. Unlike current FTJ devices, this device is comprised of asymmetric metal and semi-metallic graphene materials.

Researchers show the amphipathic nature of graphene flakes and examine their potential for use as surfactant

Researchers at Cranfield University and the University of Cambridge in the UK, Institut Pasteur in France, Silesian University of Technology in Poland and UniversIti Teknologi PETRONAS in Malaysia have found that at a particular size (below 1-micron lateral size), it is possible to achieve amphiphilic behaviour in graphene. This graphene flake attracts water at its edges but repels it on its surface, making it a new generation of surfactant that can stabilize oil and water mixtures.

In a statement, Krzysztof Koziol, Professor of Composites Engineering and Head of the Enhanced Composites and Structures Centre at Cranfield University said, “This new finding, and clear experimental demonstration of surfactant behavior of graphene, has exciting possibilities for many industrial applications. We produced pristine graphene flakes, without application of any surface treatment, at a specific size which can stabilize water/oil emulsions even under high pressure and high temperature... Unlike traditional surfactants which degrade and are often corrosive, graphene opens new level of material resistance, can operate at high pressures, combined with high temperatures and even radiation conditions; and we can recycle it. Graphene has the potential to become a truly high-performance surfactant.”

NanoGraf receives $1.65 Million from U.S. Department of Defense to Improve the batteries that power soldiers’ equipment

NanopGraf logo imageNanoGraf, an advanced battery material company, has announced that it has partnered with the U.S. Department of Defense to develop a longer-lasting lithium-ion battery, designed to provide U.S. military personnel with better portable power for the equipment they rely on to operate safely and effectively. Nanograf's graphene-wrapped silicon anode cells are hoped to significantly improve equipment runtime in the field.

The Department of Defense will provide NanoGraf with $1.65 million to develop silicon anode-based lithium-ion technology in a format compatible with all portable batteries, with a goal of enabling a 50-100 percent increase in runtime when compared to traditional graphite anode lithium-ion cells.
