Silicon-Based Nanoparticles Could Make LEDs Cheaper, Greener to ProduceResearchers at the University of Washington have created a material they say would make LED bulbs cheaper and greener to manufacture, driving down the price. Their silicon-based nanoparticles soften the blue light emitted by LEDs, creating white light that more closely resembles sunlight. |

“Popcorn” Particle Pathways Promise Better Lithium-Ion Batteries
Researchers at Sandia National Laboratories have confirmed the particle-by-particle mechanism by which lithium ions move in and out of electrodes made of lithium iron phosphate (LiFePO4, or LFP), findings that could lead to better performance in lithium-ion batteries in electric vehicles, medical equipment and aircraft. The research is reported in the journal Nano Letters, 2013, 13 (3), pp 866-872. |

Even with Defects, Graphene Is Strongest Material in the World
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. |

Innovative New Nanotechnology Stops Bed Bugs in Their Tracks - Literally
Bed bugs now need to watch their step. Researchers at Stony Brook University have developed a safe, non-chemical resource that literally stops bed bugs in their tracks. This innovative new technology acts as a man-made web consisting of microfibers 50 times thinner than a human hair which entangle and trap bed bugs and other insects. This patent-pending technology is being commercialized by Fibertrap, a private company that employs non-toxic pest control methods. |
