Columbia Engineering Professor Yuan Yang has developed a new method to increase the energy density of lithium batteries. He has built a trilayer structure that is stable even in ambient air, which makes the battery both longer lasting and cheaper to manufacture. The work, which may improve the energy density of lithium batteries by 10-30%, is published online today in Nano Letters.
Physicists at Ludwig-Maximilians-Universitaet (LMU) in Munich have developed a novel nanotool that provides a facile means of characterizing the mechanical properties of biomolecules.
A team of scientists, led by the University of Southampton, have produced a fast nanoscale optical transistor using gold nanoantenna assisted phase transition.
New research led by the University of Liverpool aims to improve the administration and availability of drug therapies to HIV patients through the use of nanotechnology.
The ultimate goal of cancer diagnostics is to develop sensitive imaging techniques for reliable detection of tumor malignancy in the body. Scientists at Tokyo Institute of Technology have come close to achieving this goal by developing an injectable imaging probe that can specifically detect solid tumors based on the activity of hypoxia-inducible factor regulated by the ubiquitin-proteasome system.
Researchers at the University of California, Riverside's Bourns College of Engineering have developed an inexpensive, energy-efficient way to create silicon-based anodes for lithium-ion batteries from the fossilized remains of single-celled algae called diatoms. The research could lead to the development of ultra-high capacity lithium-ion batteries for electric vehicles and portable electronics.
Rice University scientists smash silver micro-cubes at near supersonic speeds to see how deforming their crystalline structures can make them both stronger and tougher. The research could lead to better materials for high-impact applications like bulletproof vests, vehicle collision protection and advanced material processing techniques.
Flooring can be made from any number of sustainable materials, making it, generally, an eco-friendly feature in homes and businesses alike. Now, flooring could be even more 'green,' thanks to an inexpensive, simple method developed by University of Wisconsin-Madison materials engineers that allows them to convert footsteps into usable electricity.
A new design for transistors which operate on 'scavenged' energy from their environment could form the basis for devices which function for months or years without a battery, and could be used for wearable or implantable electronics.
Stanford and Oxford scientists have created new perovskite solar cells that that could rival and even outperform conventional cells made of silicon. The novel technology is made with tin and other inexpensive, abundant materials.
