Graphene-based transistor to increase the clock speed of processors

May 19, 2016

Scientists from the Moscow Institute of Physics and Technology (MIPT), the Institute of Physics and Technology RAS, and Tohoku University (Japan) have developed a new type of graphene-based transistor and using modelling they have demonstrated that it has ultralow power consumption compared with other similar transistor devices. Reducing power consumption enables the clock speed of processors to be increased, according to calculations, to as high as two orders of magnitude, since the electronic components heat up less.

Building transistors that are capable of switching at low voltages (less than 0.5 volts) is one of the major challenges of modern electronics. Tunnel transistors seem to be the most promising candidates to solve this problem. Unlike in conventional transistors, where electrons “jump” through the energy barrier, in tunnel transistors the electrons “filter” through the barrier due to the quantum tunneling effect. However, in most semiconductors the tunneling current is very small and this prevents transistors that are based on these materials from being used in real circuits.

Researchers demonstrate the use of graphene for thermoelectric applications

May 19, 2016

Researchers from the University of Groningen and the University of Manchester have directly detected the Peltier effect in graphene that is either one or two atoms thick. The Peltier effect is an example of Thermoelectrics: the field of study that deals with situations in which a temperature difference creates an electric potential, or vice versa. In this effect, a temperature difference appears when a voltage is applied between two electrodes connected to a semiconductor material. The team unambiguously showed that the effect can be switched from heating to cooling by tuning the type and density of the charge carriers inside the material.

The researchers used graphene because of its 2D nature, and graphene is a wonderful candidate for demonstrating a fully tuneable Peltier effect. The electrical contacts to graphene allowed to electrically control the cooling and heating via the Peltier effect, and to detect this cooling and heating, the researchers constructed sensitive nanoscale thermometers that directly measured the temperature of electrons in graphene. This practical approach is said to be the first of its kind for 2D materials, and its sensitivity is a thousand times better than that of its predecessors, down to 0.1 milliKelvin.

CealTech to start high-volume, high-quality graphene production

May 19, 2016

CealTech aims to become a leading global producer of high volume, high quality graphene, ultra-fine graphite and fine graphite. Production will be done by CealTech's independently-developed FORZA 3D graphene production unit (patent pending).

The researcher ran several experiments and measurements on a series of functionalized coronene molecules, and say that these results provide useful data for the analysis of IR and Raman spectra of GO. The researcher say that the Coronene could provide a useful model to study GO features.

Haydale announces reactor supply and collaboration agreement with Graphit Kropfmuhl , part of AMG Advanced Metallurgical Group

May 18, 2016

Haydale logoHaydale has announced a collaboration agreement with Graphit Kropfmuhl GmbH, part of AMG Advanced Metallurgical Group and an affiliate of Alterna Capital Partners. The Agreement focuses on the development of new value added nano-material products using Haydale's HDPlas functionalization process and certain AMG graphitic feedstock material primarily from its GK mine in Sri Lanka.

Haydale will initially supply an R&D reactor (HT60) and a larger capacity reactor (HT200) to GK for use under the Agreement. The initial contract value for the supply of the reactors is payable to Haydale on the normal machine supply basis. Subject to reaching the agreed milestones, the majority of the revenue is scheduled to be received in the current financial year and is expected to constitute a significant proportion of the Group’s revenues for the year ended 30 June 2016.

Graphene 3D Lab introduces a new class of graphene materials with exceptional oil absorbance properties

May 17, 2016

Graphene 3D Labs logoGraphene 3D Lab has announced a new class of graphene materials with exceptional oil absorbance properties. The Company has commissioned a new production reactor that results in a 5-fold increase in the production capabilities of Graphene Oxide and Reduced Graphene Oxide; Using this extended capacity, the Company produced a new class of materials: Graphene Oxide and Reduced Graphene Oxide Foams. These foams are in the class of ultralight materials and have density of approximately 20 mg/cm 3 , which is only about 17 times heavier than air.

These new materials are able to hold up to 3,500%-8,000% of their own weight of organic solvents and oils, all while being unaffected by water. This attribute could be significant in minimizing the damage caused by oil spills. Due to its high oil absorption capacity, these porous solid state foams are an excellent solution for fast and effective oil clean-up. In addition, they may also have commercial application in energy storage devices, chemical catalysts and ultrasensitive sensors.

Microwaving a graphene composite could improve gas & oil wells

May 17, 2016

Researchers at Rice University have shown that adding modified graphene nanoribbons to a polymer and then microwaving the mixture appears to reinforce wellbores drilled to extract oil and natural gas, which can make wells more stable and reduce production costs.

The team combined a small amount of the nanoribbons with an oil-based thermoset polymer. The combination then was cured in place with low-power microwaves emanating from the drill assembly, resulting in the composite plugging microscopic fractures. The combination allowed drilling fluid to seep through and destabilize the walls.
