UCLA engineers announce breakthrough in semiconductor spin wave research

Engineers at the UCLA Henry Samueli School of Engineering and Applied Science are announcing a critical new breakthrough in semiconductor spin-wave research.

UCLA Engineering adjunct professor Mary Mehrnoosh Eshaghian-Wilner, researcher Alexander Khitun and professor Kang Wang have created three novel nanoscale computational architectures using a technology they pioneered called “spin-wave buses” as the mechanism for interconnection. The three nanoscale architectures are not only power

Optimising the control of wind generators by means of intelligent microsensors

The School of Engineering at Bayonne (ESTIA) is working on a research project on control optimisation for the latest-generation wind generators using intelligent microsensors.

The latest-generation wind generators work at variable speed and with pitch regulation based on the pitch angle of the rotor blades. These degrees of freedom (the rotation speed and the pitch angle of each blade) enable an increase in energy yield, a decrease in fatigue due to mechanical loads and an enhanc

Andalusian researchers design alternatives with titanium dioxide to the traditional photovoltaic cell

Andalusian scientists of the University of Cadiz and Pablo de Olavide University (Seville) are working on a project of improvement in the photoelectrochemical solar cells performance, an alternative to the silicon cells that are normally used. This would entail reductions in the cost of the parts.

The semi-conduit used in most photovoltaic solar cells that are commercialised is silicon, and despite its optimum efficiency in the exploitation of solar energy, it is a material whose produ

New Chip Design Delivers Better Performance, Longer Battery Life for Cell Phones, WiFi, and Other Wireless Communications

Anyone who uses a cell phone or a WiFi laptop knows the irritation of a dead-battery surprise. But now researchers at the University of Rochester have broken a barrier in wireless chip design that uses a tenth as much battery power as current designs and, better yet, will use much less in emerging wireless devices of the future.

Hui Wu, professor of electrical and computer engineering at the University of Rochester, a pioneer in a circuit design called an “injection locked freq

Smart coatings project aims to bring more readable display screens

Smart coatings that should allow cash machine, mobile phone and laptop display screens to be read much more easily in bright sunlight could soon be on the way, thanks to a major research project unveiled today.

Scientists from the University of Abertay Dundee and the University of Greenwich are joining forces with specialist screen and thin film coatings manufacturers in the £600,000 ENDSENSE project, which is part-funded by the Department of Trade & Industry.

Nanogenerators may spark miniature machines

Devices convert simple motion into electricity

Researchers at the Georgia Institute of Technology have crafted tiny nanowires that generate electricity when they vibrate. Just like the quartz crystal in a watch, the zinc-oxide nanowires are piezoelectric, which means bending causes them to produce an electrical charge.

Only 20-40 billionths of a meter in diameter, each fiber partners with millions of others to form a nanogenerator capable of producing significant amounts o
