Chalmers team designs a graphene-based detector that may revolutionize space telescopes

Thu, 12/09/2019 - 2:38pm

Researchers from Chalmers University of Technology have demonstrated a graphene-based detector with the potential to revolutionize the sensors used in next-generation space telescopes. Beyond superconductors, there are few materials that can meet the requirements for making ultra-sensitive and fast terahertz (THz) detectors for astronomy. Chalmers researchers have shown that engineered graphene adds a new material paradigm for THz heterodyne detection.

"Graphene might be the only known material that remains an excellent conductor of electricity/heat even when having, effectively, no electrons. We have reached a near zero-electron scenario in graphene, also called Dirac point, by assembling electron-accepting molecules on its surface. Our results show that graphene is an exceptionally good material for THz heterodyne detection when doped to the Dirac point," says Samuel Lara-Avila, assistant professor at the Quantum Device Physics Laboratory and lead author of the paper.

Applied Graphene Materials launches graphene-enhanced thermally conductive epoxy paste adhesives

Tue, 10/09/2019 - 2:04pm

Applied Graphene Materials recently added new adhesive materials to their portfolio, aimed at the Space and Defense sectors. These are said to be two unique graphene-enhanced thermally conductive epoxy paste adhesive systems, called AGM TP300 and AGM TP400

These novel epoxy adhesive systems reportedly exhibit high levels of thermal conductivity (between 3 and 6 W/mK), combined with excellent mechanical, adhesive and outgassing performance. Most significantly these properties are achieved with cured resin densities as low as 40% that of competitive conductive adhesives on the market. AGM’s TP 300/400 products are therefore highly versatile, while providing end users with significant savings in both mass and cost.

Researchers achieve atomically-precise graphene origami

Sun, 08/09/2019 - 3:54pm

Past studies by various research groups around the world were able to demonstrate origami-like folding of graphite with a scanning probe, but could not command where or how the folds would occur. Now, by replacing the graphite with high-quality graphene nanoislands, researchers in China and the US have leveraged the atomic-level control of STM into an origami nanofabrication tool with an impressive level of precision.

“Similar to conventional paper origami, our current work has made it possible to create new complex nanostructures by custom-design folding of atomic layer materials,” says Hong-Jun Gao, a researcher at the Chinese Academy of Sciences (CAS) who led this latest work. Alongside Shixuan Du and collaborators at CAS, as well as Vanderbilt University and the University of Maryland in the U.S, Gao reports how they can fold single layers of graphene with the direction of the fold specified over a range from around the magic angle at 1.1° (where observations of correlated electron behavior have been causing such a stir) to 60°, with a precision of 0.1°. Their STM manipulations also leave tubular structures at the edges that have one-dimensional structure electron characteristics similar to carbon nanotubes.

Researchers gain a better understanding of heat distribution processes

Fri, 06/09/2019 - 7:00pm

Understanding atomic level processes can open a wide range of prospects in nanoelectronics and material engineering. A team of scientists from Peter the Great St. Petersburg Polytechnic University (SPbPU) recently suggested such a model, that describes the distribution of heat in ultrapure crystals at the atomic level.

The distribution of heat in nanostructures is not regulated by the laws that apply to conventional materials. This effect is most vividly expressed in the reaction between graphene and a laser-generated heat point source.

Graphene to enable super-resolution microscopy

Thu, 05/09/2019 - 7:00pm

Researchers at the University of Göttingen have developed a new method that utilizes the unusual properties of graphene to electromagnetically interact with fluorescing (light-emitting) molecules. This method allows scientists to optically measure extremely small distances, in the order of 1 ångström (one ten-billionth of a meter) with high accuracy and reproducibility for the first time. This enabled researchers to optically measure the thickness of lipid bilayers, the stuff that makes the membranes of all living cells.

The University of Göttingen team, led by Professor Enderlein, used a single sheet of graphene, just one atom thick (0.34 nm), to modulate the emission of light-emitting (fluorescent) molecules when they came close to the graphene sheet. The excellent optical transparency of graphene and its capability to modulate through space the molecules' emission made it an extremely sensitive tool for measuring the distance of single molecules from the graphene sheet. The accuracy of this method is so good that even the slightest distance changes of around 1 ångström (this is about the diameter of an atom or half a millionth of a human hair) can be resolved. The scientists were able to show this by depositing single molecules above a graphene layer. They could then determine their distance by monitoring and evaluating their light emission.

“Compared to current technology, this could enable faster, low power devices,” says Vivek Saraswat, a PhD student in materials science and engineering at UW-Madison. “It could help you pack in more transistors onto chips and continue Moore’s law into the future”. The advance could enable graphene-based integrated circuits, with much improved performance over today’s silicon chips.

First Graphene wins major production order for mining wear linings

Wed, 04/09/2019 - 6:02pm

First Graphene recently signed a new agreement with newGen for the supply of three tonnes of its PureGRAPH products. These will be used by newGen for the manufacture of wear linings used in bucket wheels, pipe spools and conveyor applications in the mining industry. This continues the two Companies' cooperation in the field of graphene-enhanced products (primarily polyurethane liners) for the mining services industry.

Blending PureGRAPH graphene in powder form with existing elastomers reportedly provides considerable mechanical improvements to the material, including enhanced tensile and tear strength, plus far greater abrasion resistance. This extends the life of wear liners, significantly reducing downtime and cost for mining and quarrying operators.

Haydale receives funding to develop Airbus-approved space technology

Graphene oxide to help regenerate cartilage

Tue, 03/09/2019 - 8:35pm

Researchers from the University of Manchester have found that incorporating graphene oxide into three-dimensional scaffolds that support regenerating cartilage could offer a new means of delivering vital growth factors.

Damage to cartilage from injury or disease is difficult to remedy because of the material’s low capacity for self-repair. Future treatments hope to harness tissue-engineering approaches, introducing hydrogel scaffolds impregnated with stem cells that can proliferate and differentiate into chondrocytes, to make new cartilage. This strategy requires the appropriate biological cues to drive cell differentiation, but the results of various attempts to achieve sustained delivery of such signals have been disappointing.

Researchers develop smallest graphene-based accelerometer ever reported

Tue, 03/09/2019 - 8:16pm

Researchers from Sweden and Germany (from KTH Royal Institute of Technology, RWTH Aachen University and Research Institute AMO GmbH, Aachen) have developed the smallest graphene-based accelerometer ever reported. This achievement has been referred to as "a breakthrough for body sensor and navigation technologies".

For the past few decades microelectromechanical systems (MEMS) have been the basis for research and innovations. Now there is a move to the next level – nano-electromechanical systems, or NEMS. Xuge Fan, a researcher in the Department for Micro and Nanosystems at KTH, says that the unique material properties of graphene have enabled them to build these ultra-small accelerometers. “Based on the surveys and comparisons we have made, we can say that this is the smallest reported electromechanical accelerometer in the world,” Fan said.
