One reason that solar energy has not been widely adopted is because light absorbing materials are not durable. Materials that harvest solar radiation for energy often overheat or degrade over time; this reduces their viability to compete with other renewable energy sources like wind or hydroelectric generators.
Thin Film Electronics ASA announced that its award-winning Addressable Memory was chosen by a FlexTech Alliance-funded consortium as a key component in a printed sensor platform to monitor temperature and blood oxygen content. Thinfilm will deliver its Addressable Memoryto the new program led by PARC, a Xerox Company, and the University of California, Berkeley (UCB).
Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have created an ultrathin, flat lens that focuses light without imparting the distortions of conventional lenses. Left to right : Francesco Aieta, Federico Capasso, and Patrice Genevet. At a mere 60 nanometers thick, the flat lens is essentially two-dimensional, yet its focusing power approaches the ultimate physical limit set by the laws of diffraction.
Google and Boingo are building on their free Wi-Fi project in New York City , launching the advertising-paid access model in eight malls across the country. Though the project is still in its infancy, it represents a growing trend to make Wi-Fi a free and readily accessible resource, while depending on ad views to pay the bill.
PayPal is confirming reports that it is test-running a new app-based checkout system in McDonald’s restaurants, a pilot program that could push the online payment broker - and the notion of phone-based payments - much further into the consumer shopping experience. It could also add confusing choices and tools to manage in an increasinly fragmented payment landscape.
If Doctor Evil ever lowered his lofty goal of sharks with frickin’ laser beams on their heads to something more manageable, such as lasers on frickin’ tadpoles, the world’s smallest laser might serve him well. Physicists from the University of Texas at Austin working with colleagues in Taiwan and China have created what they claim to be the world’s smallest laser.
I’ve got a riddle for you. What do Blu-ray disks, military radars and LED light bulbs have in common? Chances are, if you work outside of the defense or electronics sectors, you may not easily make the connection. But the common thread is a little-known technology called Gallium Nitride (GaN for short).
The firm's disruptive gallium nitride technology is to be developed for LEDs, laser diodes, and power electronics Soraa, a developer of GaN on GaN solid-state lighting technology, has been selected by Advanced Research Projects Agency-Energy (ARPA-E) to lead a project on the development of bulk GaN substrates.
National Central University (NCU) in Taiwan will use an AIXTRON metal-organic chemical vapor deposition (MOCVD) system to research gallium-nitride-on-silicon (GaN-on-Si) power semiconductors . An existing AIXTRON customer, NCU installed a 1 x 6” AIXTRON Close Coupled Showerhead MOCVD system. They will grow GaN epitaxial structures on 6” silicon substrates, which will be used in R&D of power management devices.

Researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. By eliminating the need to convert mechanical energy to electrical energy for charging a battery, the new hybrid generator-storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries.
Whether a material conducts electricity without losses is not least a question of the right temperature. In future it may be possible to make a more reliable prediction for high-temperature superconductors. These materials lose their resistance if they are cooled with liquid nitrogen, which is relatively easy to handle.
Realization of a new type of magnetic phase in devices opens the door to electronics based on topologically non-trivial materials A team of researchers at RIKEN and the University of Tokyo has demonstrated a new material that promises to eliminate loss in electrical power transmission. The surprise is that their methodology for solving this classic energy problem is based upon the first realization of a highly exotic type of magnetic semiconductor first theorized less than a decade ago - a magnetic topological insulator.
Research by Nosang Myung , a professor at the University of California, Riverside, Bourns College of Engineering , has enabled a Riverside company to develop an “electronic nose” prototype that can detect small quantities of harmful airborne substances. Nano Engineered Applications, Inc. , an Innovation Economy Corporation company, has completed the prototype which is based on intellectual property exclusively licensed from the University of California.
