An international team of materials researchers has given the engineering world a better look at the inner functions of the electrodes of supercapacitors - the low-cost, lightweight energy storage devices used in many electronics, transportation and many other applications.
Researchers showed in a recent study that a transparent active-matrix photosensor array, that can operate at high frame rates and which has potential applications in contact-free interactive displays, had been integrated.
CEA-Leti and III-V lab today announced that they have demonstrated an integrated tunable transmitter on silicon. For the first time, a tunable laser source has been integrated on silicon, which represents a key milestone towards fully integrated transceivers.
Positively charged star polymers containing a magnetic core are particularly suitable as DNA-delivery vectors. They show extremely high gene transfer efficiency and afterwards enable the quick and simple separation of the transfected cells from the transfection pool.
Researchers discovered that spider silks - particularly the draglines that anchor webs in place - conduct heat better than most materials, including very good conductors such as silicon, aluminum and pure iron. Spider silk also conducts heat 1,000 times better than woven silkworm silk and 800 times better than other organic tissues.
Fazel Yavari has developed a new sensor to detect extremely small quantities of hazardous gases. Made from a 3-D foam of graphene, this sensor is durable, inexpensive to make, and opens the door to a new generation of gas detectors for use by bomb squads, defense and law enforcement officials, as well as applications in industrial settings.
IBM's Battery 500 project, led by scientists at IBM Research - Almaden in California, is an interdisciplinary consortium to develop a lithium-air battery that aims to increase the range of electrovehicles to 500 miles (approximately 800 km). This is more than five times the range of today's batteries, which average some 150 km per charge.
