 | Cheaper clean-energy technologies could be made possible thanks to a new discovery. An important chemical reaction that generates hydrogen from water is effectively triggered -- or catalyzed -- by a nanoparticle composed of nickel and phosphorus, two inexpensive elements that are abundant on Earth. The research team is led by Raymond Schaak, a professor of chemistry at Penn State University. ...> Full Article |

 | Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures -- including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals. ...> Full Article |
 | Il-Doo Kim, Associate Professor of Materials Science and Engineering Department at the Korea Advanced Institute of Science and Technology, and his research team have recently developed a highly sensitive exhaled breath sensor by using hierarchical SnO2 fibers that are assembled from wrinkled thin SnO2 nanotubes. ...> Full Article |
 | Researchers at ICFO have developed a new technique for measuring very weak forces on a molecular scale. Thanks to the use of carbon nanotubes, they have achieved the highest level of sensitivity to date. These results published in Nature Nanotechnology open the door for magnetic resonance imaging of individual molecules. ...> Full Article |
 | Detecting one individual biomolecule amongst millions of other neighboring molecules has been technically impossible until now. Scientists at the Fresnel Institute and ICFO-The Institute of Photonic Sciences have devised the smallest optical device capable of detecting and sensing individual biomolecules at concentrations that are similar to those found in the cellular context. ...> Full Article |
 | The research team of Ulsan National Institute of Science and Technology (UNIST), Case Western Reserve University and University of North Texas have paved a new way for affordable commercialization of fuel cells with efficient metal-free electrocatalysts using edge-halogenated graphene nanoplatelets. ...> Full Article |
 | Columbia Engineering researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its perfect crystalline form. This resolves a contradiction between theoretical simulations, which predicted grain boundaries can be strong, and earlier experiments, which indicated they were much weaker than the perfect lattice. "We're excited to say that graphene is back and stronger than ever," says Mechanical Engineering Professor James Hone. ...> Full Article |
High-performance thermoelectric materials that convert waste heat to electricity could one day be a source of more sustainable power. But they need to be a lot more efficient before they could be effective on a broad scale in places like power plants or military bases, researchers say.

 | A hybrid transparent and stretchable electrode could open the new way for flexible displays, solar cells, and even electronic devices fitted on a curvature substrate such as soft eye contact lenses, by the UNIST(Ulsan National Institute of Science and Technology) research team. ...> Full Article |
What may be the ultimate heat sink is only possible because of yet another astounding capability of graphene. The one-atom-thick form of carbon can act as a go-between that allows vertically aligned carbon nanotubes to grow on nearly anything, including diamonds.
