Researchers from the University of Bristol have measured and identified for the first time the stress and strain shear modulus and internal friction of graphene sheets. Graphene is a material that has many potential groundbreaking uses in the electronics and composites industry. The research, in collaboration with the US Office of Naval Research, is published in Nano Letters. Graphene is made up of a single layer of carbon atoms arranged in a hexagonal lattice. It is a promising...

Fuel consumption and emissions can be reduced with new technology No less than one third of a car's fuel consumption is spent in overcoming friction, and this friction loss has a direct impact on both fuel consumption and emissions. However, new technology can reduce friction by anything from 10% to 80% in various components of a car, according to a joint study by VTT Technical Research Centre of Finland and Argonne National Laboratory (ANL) in USA. It should thus be possible to reduce...

Similar to the way pavement, softened by a hot sun, will slow down a car, graphene–a one-atom-thick sheet of carbon with wondrous properties–slows down an object sliding across its surface. But stack the sheets and graphene gets more slippery, say theorists at the National Institute of Standards and Technology (NIST), who developed new software to quantify the material's friction. "I don't think anyone expects graphene to behave like a surface of a three-dimensional material,...

Lubricant in devices found to be graphite, not proteins A new study, bringing together an interdisciplinary team of physicians and engineers from the United States and Germany, made a surprising finding about implants used in hip replacement surgery: Graphite carbon is a key element in the lubricating layer that forms on metal-on-metal hip implants. The lubricant has more in common with the lubrication of a combustion engine than that of a natural joint. The study was funded by the...

It's easy to get in a jam. But it's much harder to explain exactly how or when it started. Scientists still aren't sure what causes clogs in flowing macroscopic particles, like corn, coffee beans and coal chunks. But new experiments by Duke physicist Robert Behringer and his colleagues suggest that when particles undergo a force called shear strain, they jam sooner than expected. The results appear in the Dec. 15 issue of Nature. Shear strain is sort of like cupping sand between your...

They should prove a challenge for the athletes, but not put them in danger: bobsled runs have to be simulated before being built. This simulation is based on the friction levels of the runners on the ice. Now it has become possible to measure these levels accurately. These results will help build the run for the 2014 Olympic Winter Games. Lightning fast, the sled bolts down the icy run. Will the team make it to the finish faster than their competitors? The tension in the crowd depends...
