Chalmers team demonstrated graphene films with higher thermal conductivity than that of graphite films

Researchers at Chalmers University of Technology in Sweden, have developed a graphene assembled film that has over 60% higher thermal conductivity than graphite film – despite the fact that graphite consists of many layers of graphene. The graphene film shows great potential as a novel heat spreading material for form-factor driven electronics and other high power-driven systems. The IP of the high-quality manufacturing process for the graphene film belongs to SHT Smart High Tech AB, a spin-off company from Chalmers, which is going to focus on the commercialization of the technology.

Until now, many scientists in the graphene research community have assumed that graphene assembled film cannot have higher thermal conductivity than graphite film. Single layer graphene has a thermal conductivity between 3500 and 5000 W/mK. If you put several graphene layers together, then it theoretically becomes graphite.

Talga Resources reports breakthrough on its graphene-infused concrete project

Australia-based advanced materials company Talga Resources has reported high levels of electrical conductivity in concrete by using an additive developed from the Company’s graphene-graphite research and development laboratory in the UK.

Talga reports advancements of graphene-enhanced concrete project image(L) Talga concrete sample after melting 5cm depth of ice from 9v power. (R) Conceptual underfloor heating/road application.

The reported breakthrough offers substantial potential in existing and emerging industrial applications, particularly as concrete is the world’s largest construction material by volume. Talga shared information gathered from tests that show that the graphene-enhanced concrete is highly electrically conductive - attaining 0.05 ohm.cm volume resistivity.

IIT Madras develops rGO-based wound dressing material to treat diabetic wounds

Researchers at Indian Institute of Technology (IIT) Madras have developed reduced graphene oxide loaded nanocomposite scaffolds for treating normal and diabetic wounds.

Wounds in diabetic patients do not heal as rapidly as it would in a normal and healthy individual, which leads to chronic non-healing wounds that can result in serious complications. Treatment of such chronic non-healing wounds in diabetes is still a major clinical challenge. Although there are some wound dressings that are commercially available, they are very expensive.

Urbix Resources announces series A funding oversubscribed at $3.5 Million

Urbix Resources logo imageU.S-based startup Urbix Resources has announced closing its Series A round of financing with an oversubscribed commitment of $3.5 million USD. The Company states that in addition to current investors and management, this round included an international investment from a management company based in Mexico.

“It was gratifying to find ourselves in a position where our funding objectives were oversubscribed,” comments Executive Chairman Nico Cuevas. “This allows us to focus on our main initiatives including the construction of our low-cost/clean tech pilot purification facility and the construction of our proprietary pristine graphene reactor. This leads us to our goal of bringing graphene at a commercial scale to the market at about $1 per gram.”

Archer to collaborate with UNSW on graphene-based batteries

Australia-based mining company Archer Exploration has announced a collaboration agreement with the University of New South Wales (UNSW) to develop and implement Archer’s graphite and graphene materials for use in energy storage system applications targeting lithium-ion batteries.

The collaboration will mainly focus on the design of high-performance electrodes for lithium-ion batteries using graphite and graphene sourced from Archer’s Campoona deposit. This work is aiming at the development of electrodes for lithium-ion batteries and implementation of these electrodes in a number of advanced application full-cell and half-cell configurations.
