Isamu Akasaki and Hiroshi Amano of Japan and U.S. scientist Shuji Nakamura won the 2014 Nobel Prize in physics for the invention of blue light-emitting diodes, a breakthrough that spurred the development of light-emitting diode (LED) technology. Scientists had struggled for decades to produce the blue diodes that are a crucial component in producing white light from LEDs when the three laureates made their breakthroughs in the early 1990s.

We already charge our toothbrushes and cellphones using contactless technology. Researchers in Germany have developed a particularly efficient and cost-effective inductive method that could allow electric cars to soon follow suit. The new design places the charging coils close to the car’s undercarriage without actually touching it. The charging station is also robust enough to be driven over.
The doubling of transistors on a microprocessor occurs roughly every two years, and is the outcome of what is called Moore’s Law. In a bid to continue this trend of decreasing transistor size and increasing computation and energy efficiency, chip-maker Intel has partnered with Lawrence Berkeley National Laboratory to design an entirely new kind of photoresist, one that combines the best features of two existing types of resist.
Pasternack Enterprises, Inc., a manufacturer and supplier of RF, microwave and millimeter wave products, has announced its expanded line of 75 Ohm F attenuators. This new line of F-type attenuators is designed for broadcast, HDTV and satcom applications in the L and S microwave bands up to 3 GHz.
At the 2014 Symposium on VLSI Technology in Triangle Park, N.C., researchers from the Univ. of California, Santa Barbara introduced the highest-performing class III-V metal-oxide semiconductor field-effect transistors (MOSFETs) yet demonstrated. The new MOSFETs exhibit, in an industry first, on-current, off-current and operating voltage comparable to or exceeding production silicon devices, while also staying relatively compact.
Crystal IS has introduced Optan, the first commercial semiconductor based on native aluminum nitride (AIN) substrates. Optan increases detection sensitivity from monitoring of chemicals in pharma manufacturing to drinking water analysis.
Materials that control heat flow are available with both high and low conductivities, but materials with variable and reversible thermal conductivities are rare. For the first time, researchers at the Univ. of Illinois have experimentally shown that the thermal conductivity of lithium cobalt oxide, an important material for electrochemical energy storage, can be reversibly electrochemically modulated over a considerable range.
Saudi Arabian-based petrochemical company SABIC and Cima NanoTech have announced the joint development of a new transparent conductive polycarbonate film. The collaboration leverages both Cima NanoTech’s proprietary SANTE nanoparticle technology and SABIC’s LEXAN film to produce a film that outperforms indium tin oxide by a factor of ten.
First proposed for memory in the 1970s, phase-change materials exhibit two metastable states which can store data when placed between two electrically conducting electrodes. IBM researchers in Zurich have recently used them as part of Project Theseus to develop a PCI-e card that melds flash memory with phase-change memory. The major improvement in speed interests IBM for Big Data applications.
IBM scientists have developed a new tool inspired by hieroglyphics. The core of the technology is a tiny, heatable silicon tip with a sharp apex 100,000 times smaller than a sharpened pencil. Working like a 3-D printer it “chisels” away material by local evaporation. They have used this invention to make a magazine cover for National Geographic that is just 11 by 14 micrometers in size.
A research team has developed a small electronic sensing device that can alert users wirelessly to the presence of chemical vapors in the atmosphere.
Commercial demand is driving high-tech research and development in micro-optoelectromechanical systems (MOEMS) for diverse applications such as space exploration, wireless systems, and healthcare. A new special section on Emerging MOEMS Technology and Applications in the current issue of the Journal of Micro/Nanolithography, MEMS, and MOEMS discusses these recent breakthrough achievements.
The rotor and mast of a wind turbine can oscillate and this plays a big role in equipment development and maintenance. Up to now, this analysis has only been possible at discrete points located directly on equipment. Engineers are now using modern information technology to remotely measure the oscillatory pattern over the entire structure of the facility from several hundred meters away.
Samsung Electronics Co. has beefed up the camera in its Galaxy S5 smartphone due for April release and added smarter camera software, following Sony and Nokia in their upgrades of handset cameras. The tweaks mean smartphone photos, ubiquitous nowadays because of social media such as Facebook and Twitter, will be closer in quality to images captured by digital single-lens reflex cameras, also known as DSLR.
Panasonic Corp. is considering setting up a new plant jointly with Tesla Motors Inc. in the United States to make lithium-ion batteries for electric vehicles. The Japanese electronics maker is mulling asking Japanese materials makers to set up bases at the new plant to create integrated production of batteries and is also considering supplying batteries to Toyota.
Additive manufacturing, or 3-D printing, offers a compelling alternative to more traditional manufacturing approaches at NASA, where the need for highly customized spacecraft and instrument components is quite high. The agency has recently launched a number of formal programs to prototype new 3-D printed components, including rocket engine injectors, and 3-D printers for use in space.
The new Model 5R7-388 RoHS compliant temperature controller from Oven Industries offers bi-directional control for independent thermoelectric modules or in conjunction with auxiliary or supplemental resistive heaters for both cooling and heating applications.
According to Anupam Agrawal, a professor of business administration at the Univ. of Illinois, Urbana-Champaign, firms can manage their sourcing better by developing relationships not only with their suppliers but also with their suppliers’ suppliers. The lack of communication or collaboration between the big players at either end of the supply chain spectrum can prevent gains in efficiencies.
A 310-foot "crop circle" in a California barley field that mystified locals this week was explained Sunday: it was a publicity stunt by Nvidia Corp., a maker of chips for PCs and smartphones. The company has announced the Tegra K1, a new chip for tablets and smartphones that contains 192 computing "cores," or mini-computers, for graphics applications.
Innovations in Optics, Inc. has introduced a full product line of LumiBright UV LE Ultraviolet LED (light-emitting diode) light engines. The versatile and powerful solid-state sources are ideal for ultraviolet (UV) applications in life science, medical, and industrial equipment.

Google may be gearing up to build robots that resemble props in science-fiction movies as the ambitious Internet company expands into yet another technological frontier. To gather the expertise and research it needs, Google has purchased eight companies that specialize in robotics this year. The acquisitions are being assembled into a new robotics division headed by Andy Rubin, who oversaw Google's development of Android.
Equipped with a new generation of drivers, the RM05-8A-S PCB mount reed relay module from Standex-Meder Electronics offers a 24% smaller footprint than the RM05-8A model. It is ideal for test and measurement, high frequency and telecommunications applications.
Two of the key instruments aboard NASA’s Curiosity rover on Mars are the CheMin, a mineral sample analyzer, and the ChemCam, a spectroscopic imaging system. Both systems require precise, fast motion control, capable of surviving a harsh environment. Jet Propulsion Laboratory engineers found a solution with piezo-based technology from Physik Instrumente and miCos. But first it would need to pass rigorous testing.
A recently developed plasma-based chip fabrication technique affords chip makers unprecedented control of plasma thanks to a population of suprathermal electrons. This is critical to modern microchip fabrication, but how the beam electrons transform themselves into this suprathermal population has been a puzzle. New computer simulations reveal how intense plasma waves generate suprathermal electrons.
