Arizona State University researchers are finding ways to improve infrared photodetector technology that is critical to national defense and security systems, as well as used increasingly in commercial applications and consumer products.
Carbon nanotubes and graphene consist of just a couple of layers of carbon atoms, but they are lighter than aluminium, stronger than steel and can bend like spring-coils. Physicist Niklas Lindahl at the University of Gothenburg, Sweden, has been studying the unique properties of the materials, which in future may result in improved electronics and light, strong material.
As a result of a joint intensive work of several groups from five different countries, including Basque Country, a new wide class of topological insulators - materials that are insulators in the bulk but conductors at the surface - with technologically very promising properties has been discovered.
The technology that Google uses to analyze trillions of Web pages is being brought to bear on the way molecules are shaped and organized. A researcher has adapted Google's PageRank software to create moleculaRnetworks, which scientists can use to determine molecular shapes and chemical reactions without the expense, logistics and occasional danger of lab experiments.
The theme of this year's World Congress on Brain, Spinal Cord Mapping, and Image Guided Therapy is "Nano-Bio-Electronics", which focuses on the integration of nanotechnology, stem cell research, and biomedical engineering, and imaging of the brain and spinal cord to make progress in the fight against neurological diseases.
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science and UCLA's California Nanosystems Institute report that they have significantly enhanced polymer solar cells' performance by building a device with a new "tandem" structure that combines multiple cells with different absorption bands. The device had a certified power-conversion efficiency of 8.62 percent and set a world record in July 2011.
Individual atoms can make or break electronic properties in one of the world's smallest known conductors - quantum nanowires. Microscopic analysis is delivering a rare glimpse into how the atomic structure of the conducting nanowires affects their electronic behavior.
