Group NanoXplore, a Montreal-based company specializing in the production and application of graphene and its derivative materials, announced that it will merge with Graniz Modal, a public company that trades in the Canadian stock exchange (TSX: GRA.H). Effectively, NanoXplore will become a public company.

As part of the transaction, NanoXplore will also make a brokered private placement and will raise between $2 million and $5 million CAD.

An international team of scientists collaborating in the Graphene Flagship project has developed a graphene-based transistor that reportedly outperforms previous state-of-the-art ones. The team utilized a thin top gate insulator material to optimize operational properties like maximum oscillation frequency, cutoff frequency, forward transmission coefficient, and open-circuit voltage gain, realizing devices that show prospect of using graphene in a wide range of electronic applications.

Graphene lack of a bandgap hinders its use in electronics since it causes an inability to switch the transistors off, effectively rendering the “0” state in digital logic inaccessible. However, many analog applications do not require a bandgap; The team explains that the only undesired side-effect of using GFETs in analog circuits is a poor saturation of the drain current, which prevents high-gain operation. The researchers have now succeeded in improving saturation by optimizing the dielectric material (AlOx) that is used to electrically insulate the top gate of the GFET. An improved quality of gate dielectric resulted in strong control over carriers in the graphene channel, yielding overall performance benefits.

Australian technology minerals company, Talga Resources, announced a funding initiative to raise gross proceeds of $12.3 million AUD (around $9.2 million USD). The Placement is being made to a small group of targeted institutions and was also strongly supported by a group of Talga’s major shareholders.

The Company intends to use these funds towards Talga’s commercial, processing, product development and mineral development programs in Europe as well as for general working capital.

Skeleton Technologies has unveiled SkelGrid, an energy storage system for industrial power applications, based on the company's curved graphene supercapacitor technology. The system is meant to ensure reliable power quality in manufacturing plants, data centers, and more.

SkelGrid is said to provide the highest power and energy density on the market in the industry standard electrical cabinet or container format. The SkelGrid product family is based on SkelRack modules, which can be installed in industry standard 19”, 600mm deep cabinets, and in 20 or 40 ft. containers to provide short-term power at the megawatt level. The SkelGrid family has maximum power ratings ranging from 520 kW up to 1500 kW, and as a modular product, its components can be configured according to customers’ needs.
