Sparc Technologies reports successfull testing of graphene-enhanced epoxy coatings

In 2020 Sparc Technologies acquired Graphene Technology Solutions (GTS) and announced plans to become a “significant developer of graphene-based products".

Sparc announced today that after six months of testing, its graphene-based additives was found to offer up to 40% improvement in the anti-corrosive performance of atmospheric epoxy coatings. The company used commercially available epoxy coatings available from leading coatings manufacturers.

Researchers stabilize the edges of graphene nanoribbons and measure their magnetic properties

Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley have developed a method to stabilize the edges of graphene nanoribbons and directly measure their unique magnetic properties.

The team, co-led by Felix Fischer and Steven Louie from Berkeley Lab’s Materials Sciences Division, found that by substituting some of the carbon atoms along the ribbon’s zigzag edges with nitrogen atoms, they could discretely tune the local electronic structure without disrupting the magnetic properties. This subtle structural change further enabled the development of a scanning probe microscopy technique for measuring the material’s local magnetism at the atomic scale.

New graphene-based neural probes improve detection of epileptic brain signals

Researchers the UK and Spain have demonstrated that tiny graphene neural probes can be used safely to improve our understanding of the causes of epilepsy.

The graphene depth neural probe (gDNP) consists of a millimeter-long linear array of micro-transistors imbedded in a micrometer-thin polymeric flexible substrate. The transistors were developed by a collaboration between The University of Manchester’s Neuromedicine Lab and UCL’s Institute of Neurology along with their Graphene Flagship partners.

Researchers develop graphene-biosensors for brain machine interfaces

Researchers at the University of Technology Sydney (UTS) have developed a novel graphene-based biosensor, set to drive new innovations in brain-controlled robotics.

The biosensor adheres to the skin of the face and head in order to detect electrical signals being sent by the brain. These signals can be translated into commands to control autonomous robotic systems. The sensor, made of epitaxial graphene grown onto a silicon carbide on silicon substrate, overcomes the major challenges of corrosion, durability and skin-contact resistance.

Latvia invests in project to develop graphene-enhanced ballistic protective vest

Latvia has allocated $1.4 million divided between three innovative projects that aim to improve electromagnetic protection and cybersecurity and to develop a ballistic protective vest to protect UAVs.

The project for a prototype of a ballistic protective vest will feature a pressure-sensitive layer with graphene and silicon aerogel for accurate reception of impact. This effort has been awarded funding of €449,000 ($508,000).

Researchers examine the mechanism of electric field detection in microscale graphene sensors

Researchers at Japan Advanced Institute of Science and Technology (JAIST) and Otowa Electric, a lightning protection equipment manufacturer, have used graphene as an electric field sensor that can detect both positive and negative electric fields.

Revisiting the Mechanism of Electric Field Sensing in Graphene Devices image

The response of the sensor is recorded as the change in drain current under the application of an electric field. In addition, by systematic analysis, The team established the mechanism of the graphene electric field sensor, which was found to be different from what they expected.

GIT's graphene coating to be tested on large ships

Graphite Innovation and Technologies (GIT) uses graphene as the base for its strong, slippery and non-toxic hull paint. The coating helps prevent marine fouling – when aquatic organisms such as barnacles stick to the hull – thus improving the flow of water against the vessel, making it more efficient. Now, the coating will be heavily tested on large vessels operated by Oceanex and Baffin Fisheries.

“The vessels operated by Oceanex and Baffin Fisheries are larger vessels that move at a much higher speed than the small inshore fishing vessels previously tested under our contract with Transport Canada,” said Mo AlGermozi, President of Graphite Innovation and Technologies. “It is so much more comparable to the large transport vessels that we target as key customers, as transport fleets are more interested in reducing fuel costs and improving their environmental impact.”

Graphene Composites announces R&D partnership with ABBS for graphene-based armored vehicle protection technologies

Graphene Composites (GC) has announced a research and development partnership with Advanced Blast & Ballistic Systems (ABBS), a leading developer of active systems for protecting armored vehicles from mine and IED blasts.

The partnership will focus on the use of GC’s nanomaterials engineering technologies – particularly GC Shield® technology – to improve blast and ballistic protection performance of its systems, with testing and FEA modelling which explores the use of graphene enhanced materials as a part of its continued development of the underbelly blast plate.

Black Swan Graphene plans to go public at the TSX

Black Swan Graphene aims to go public, expecting to trade at the Toronto Venture Exchange (TSX). the company will do so as a merger with capital pool company Dragonfly Capital Corp. As part of the deal, the company will raise $5 million CAD.
