Researchers at Queen Mary University of London have shown that graphene is 3D as well as 2D. Image: Yiwei Sun. Graphene is actually a three-dimensional (3D) material as well as a two-dimensional (2D) material, according to a new study from researchers at Queen Mary University of London in the UK. Realizing that graphene is a 3D material is important for understanding its mechanical properties and for developing novel graphene-based devices. Often hailed as a 'wonder material', graphene has the highest known thermal and electrical conductivity and is stronger than steel, as well as being light, flexible and transparent. Its uses are wide-ranging and recently it was shown that it could even act as a barrier against mosquito bites (see ). In t.

This grid of simulated atoms illustrates how the electrons in cuprate high-temperature superconductors can either hop to their immediate neighbors or diagonally across each square, with superconductivity only arising when they hop diagonally. Copper atoms are in orange, oxygen atoms are in red and electrons are in blue. Image: Greg Stewart/SLAC National Accelerator Laboratory. Researchers at Stanford University and the US Department of Energy's SLAC National Accelerator Laboratory say they have found the first, long-sought proof that a decades-old scientific model of material behavior can be used to simulate and understand high-temperature superconductivity. This finding, reported in a paper in , could be an important step toward producing

Spanish company MontefibreCarbon has received €5.6 million to help it transition from from producing textile acrylic fiber to polyacrylonitrile (PAN) precursor for conversion to carbon fiber (precursor fiber). The grant comes from the Spanish Ministry of Industry, Trade & Tourism as part of the country’s REINDUS (Reindustrialization and Strengthening of Industrial Competitiveness) initiative, the company said and is part of a €7.5 million investment in Montefibre’s 302,656 m2 factory in Miranda de Ebro, Spain. Montefibre Carbon is adapting its polymerization and dope preparation with a potential capacity of 75,000 metric tons per year, and four of its seven spinning lines to produce around 17,000 tons per year of its large-tow precursor fib.

The new flash sintering process helps to overcome the brittle nature of ceramics and make them more durable. Image: Purdue University/Chris Adam. Something as simple as an electric field could soon make everything from wartime missiles to drinking mugs easier to produce and more resilient to fracture. Items such as drinking mugs, missile heads, thermal barrier coatings on engine blades, auto parts, and electronic and optic components are commonly made with ceramics. But while ceramics are mechanically strong, they tend to fracture suddenly when just slightly strained under a load unless exposed to high temperatures. Researchers at Purdue University have now developed a new process to help overcome the brittle nature of ceramics and make the.

Photographs showing tilted view of sliced sample. Light-emitting images show orange background (in-plane E field), green zigzag pattern (vertical E field), and simultaneous emission of orange and green lights (in-plane + vertical E fields), respectively, after applying an AC voltage between A and B, A+B and C, and A and B+C fibers. Electroluminescent (EL) devices based on light-emitting phosphors embedded in polymers could be useful in novel soft robots, self-healing systems, and wearable electronics. One of the most promising composites is zinc sulfide (ZnS) mixed with polydimethylsiloxane (PDMS), sandwiched between electrodes made from graphene, silver nanowires (Ag NWs), or indium tin oxide (ITO). ITO is a well-established electrode mate.

This illustration shows a dielectric metamaterial with infrared light shining on it. Image: Willie Padilla, Duke University. Electrical engineers at Duke University have harnessed the power of machine learning to design dielectric (non-metal) metamaterials that absorb and emit specific frequencies of terahertz radiation. Their design technique reduced what could have taken more than 2000 years of calculation into just 23 hours, clearing the way for the design of new, sustainable types of thermal energy harvesters and lighting. The engineers report their findings in a paper in . Metamaterials are synthetic materials composed of many individual engineered features, which together produce properties not found in nature through their structure

An electron microscope image shows an array of thermal light emitters created by engineers at Rice University; the emitters are able to deliver highly configurable thermal light. Image: The Naik Lab/Rice University. What may be viewed as the world's smallest incandescent lightbulb is shining in an engineering laboratory at Rice University, offering the promise of advances in sensing, photonics and perhaps computing platforms beyond the limits of silicon. Gururaj Naik of Rice's Brown School of Engineering and graduate student Chloe Doiron have assembled unconventional ‘selective thermal emitters’ – collections of near-nanoscale materials that absorb heat and emit light. Their research, reported in a paper in , one-ups a recent technique deve.

UB researchers work with a dual-chamber thin-film deposition system that can be used to synthesize thin-film materials. In the new study, this machine was used to create europium sulfide films and tungsten trioxide, a precursor for 2D tungsten disulfide. Photo: Douglas Levere/University at Buffalo. A new study on two-dimensional tungsten disulfide (WS 2 ) could open the door to advances in quantum computing. In a paper in Nature Communications , scientists report that they can manipulate the electronic properties of this super-thin material in ways that could be useful for encoding quantum data. The study deals with WS 2 's energy valleys, which University at Buffalo (UB) physicist Hao Zeng, co-lead author of the paper, describes as "the lo.
