The product seems to be a highly-conductive film that can be used in electric vehicle batteries, to dissipate heat in electronic devices and in solar power generation and flexible screens, according to the company. It reportedly plans to begin mass production early next year.

Researchers create efficient and low-cost graphene-enhanced lubricant

Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have been working replace oil with solid lubricants such as graphene. Argonne’s Laboratory Directed Research and Development (LDRD) Program supplied the seed money needed to begin experimentation towards that end. This work may have far reaching implications both inside and outside the automobile industry. It could help wind turbines move with greater ease, allowing them to produce more energy. It also can better seal off machinery as it pumps oil or gas from the ground or out at sea.

Graphene can also be used to better protect ball bearings, which can corrode over time when exposed to water, a process commonly referred to as tribo-corrosion. The Argonne-developed process based on graphene has shown that a few layers of graphene not only reduced friction in steel rubbing against steel by seven times and the wear by 10,000 times but also significantly reduced the tribo-corrosion problem.

Promethient receives funds to ramp up its graphene-enhanced seat warming application

Promethient, an early stage U.S-based company that developed graphene-enhanced seat warmer technology, has received a large (though undisclosed) equity investment from Faurecia Ventures, the investment arm of Nanterre, France-based Faurecia, the sixth-largest auto supplier in the world, with a big American presence.

The funding will allow Promethient to ramp up product development and marketing and also provides it with a very large early customer. The investment will also allow Promethient to sell to other auto suppliers and makers.

NanoXplore announces the acquisition of Sigma Industries

NanoXplore logoNanoXplore, manufacturer and supplier of high-volume graphene powder for use in industrial markets, has announced that it acquired Sigma Industries in a deal that included cash and stock components. The cash component is approximately CAD$9 million (around $6.8 million USD) and the stock value is approximately CAD$9.8 million (almost $7.5 million USD).

Sigma Industries is a manufacturing company specializing in the manufacture of composite products, with two operating subsidiaries and 275 employees. It operates in the markets for heavy trucks, buses, public transit, machinery and wind energy. Sigma sells its products to original equipment manufacturers and distributors in the United States, Canada and Europe.

Versarien provides updates on several energy storage R&D fronts

Versarien LogoVersarien, the advanced materials engineering group, has provided an update on its activities in relation to graphene-enhanced power storage devices like batteries and supercapacitors. The primary goal of incorporating graphene into these devices, Versarien says, is to significantly increase power storage capacity and reduce charging times.

Versarien has been working with WMG (Warwick Manufacturing Group) and their partner companies and scientists at the universities of Warwick and Cambridge to collaborate on the production of power storage devices such as batteries and supercapacitors using Versarien's proprietary Nanene graphene nano platelets. Significant advances have been made through incorporating the Company's high quality graphene into these devices and the Company looks forward to commercial products becoming available in due course.
