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.
Highly efficient 3V cathodes for rechargeable sodium-ion batteries have been developed. With a near-theoretical capacity of 250 mAh/g, excellent rate capability and cycle life, and high energy and power densities of 760 Wh/kg and 1200 W/kg, respectively, these bilayered V2O5 systems can be used in applications at ambient temperature.
A new, single-step method of fabricating microcapsules, which have potential commercial applications in industries including medicine, agriculture and diagnostics, has been developed by researchers at the University of Cambridge.
A discovery by a research team at North Dakota State University, Fargo, and the National Institute of Standards and Technology (NIST), shows that the flexibility and durability of carbon nanotube films and coatings are intimately linked to their electronic properties. The research could one day impact flexible electronic devices such as solar cells and wearable sensors.
Scientists under the direction of ETH Zurich have created a minor sensation in synthetic chemistry. They succeeded for the first time in producing regularly ordered planar polymers that form a kind of "molecular carpet" on a nanoscale.
Researchers at Northwestern University have developed a new method for creating scaffolds for tissue engineering applications, providing an alternative that is more flexible and less time-intensive than current technology.
