National Graphene Institute ‘almost empty’ say reports; researchers concerned about IP leaking to China

NGI - fancy

The National Graphene Institute (NGI) is deserted because the 250 Manchester University researchers working on graphene don’t trust it to keep secrets out of the hands of a Taiwanese-controlled company called BGT which has links to a mainland China university and a Chinese manufacturer, reports the Sunday Times. Is this true? “No”, replied the NGI. “How many people are working at ...

Graphene used for brain electrode in Parkinson treatment

graphene

Researchers in the UK and Italy believe a breakthrough in treatment of motor disorders, such as epilepsy or Parkinson’s disease, may be possible and with electronic neuron interface devices fabricated from pure graphene, writes Richard Wilson. Treatment of patients with motor disorders such as Parkinson’s disease could one day benefit from graphene, the highly conductive material which is expected to ...

TFETs may challenge MOSFETs

image

Researchers at Michigan Technological University (MTU) have developed a method for producing TFETs that overcome a key obstacle to their adoption: the need to be operated at cryogenic temperatures. Eliminating semiconductor materials in the design of their nanotube-based TFET has allowed the MTU researchers to fabricate a device that can operate at room temperatures and offers the added feature of ...

MIT fabs IC with different materials in same layer

image

MIT researchers have fabbed an IC by depositing ‘significantly different’ materials in the same layer, a few atoms thick. “The methodology is universal for many kinds of structures,” says researcher Xi Ling. “This offers us tremendous potential with numerous candidate materials for ultra-thin circuit design.” The technique also has implications for the development of  ultra-low power, high-speed tunnelling transistors and ...

UK researchers say supercapacitor clothes can power smartphones

brunel

What if the materials used for clothing could be supercapacitor elements capable of powering your smartphone? This is what industrial design researchers at Brunel University London believe could be possible. Technology to produce supercapacitor thread capable of being made into cloth has been developed in the lab before but has been unable to generate the voltages needed to power smartphones. Now ...

Three Si photonics platforms delivered by EU R&D project

image

CEA-Leti,and its partners have developed three silicon photonics platforms under the four year €10.2 million EU PLAT4M project. Leti’s platform delivers multilevel silicon patterning on 200mm SOI wafers allowing the design of various passive and active devices (such as modulator and photodiode) with thermal tuning capability. Two AlCu levels are available for routing. A PDK is available for circuit design ...

Research cools solar cells for efficiency boost

Solar cells work more efficiently when they are cooled, but sitting the the sun all day, it is not always easy to achieve this. Researchers at Stanford University in the US have come up with a transparent overlay material that increases efficiency by cooling the cells even in full sunlight. The material works by radiating heat away from the solar cells. ...

Manchester researches 3D printed graphene ink batteries

UK has world-leading graphene research

Batteries could one day be 3D-printed on the desktop using graphene ink, say researchers in Manchester. A government-funded project at Manchester Metropolitan University wants to use the city’s pioneering expertise in graphene technology to develop a desktop printer which will be used to create batteries and supercapacitors that could be used for energy storage in devices from solar power generators to smartphones. ...

Graphene-based film can super cool LEDs

Untitled-300x182.jpg

Researchers at Chalmers University of Technology have developed a method for efficiently cooling electronics using graphene-based film. According to the researchers, the graphene film has a thermal conductivity capacity that is four times that of copper. Significantly the team has developed a graphene film that  can be attached to silicon substrates. Research team leader Johan Liu, professor at Chalmers University of Technology, ...
