Imec realized large-area (70cm2) epitaxial solar cells with efficiencies of up to 16.3% on high-quality substrates. And efficiencies of up to 14.7% were achieved on large-area low-quality substrates, showing the potential of thin-film epitaxial solar cells for industrial manufacturing. The results were achieved within imec’s silicon solar cell industrial affiliation program (IIAP) that explores and develops advanced process technologies aiming ...

Federal-Mogul Corporation has developed a new piston ring coating that supports vehicle manufacturers’ efforts to make gasoline engines more fuel-efficient. The company’s patented CarboGlide® coating delivers a direct improvement in fuel economy and CO2 emissions by reducing ring friction by up to 20 percent as compared to nitride or other commonly used coatings. CarboGlide’s high wear resistance will withstand an engine’s full operatio...

Renesas Electronics today announced the development of the V850E2/Fx4-L series with 19 new 32-bit microcontrollers (MCUs). Designed for the automotive comfort and body segment, the low-power MCUs offer scalability and compatibility combined with sophisticated peripheral functions to provide premium automotive body solutions for applications such as roof or window lifters, door-, seat- and light modules, HVAC (heating, ventilation, and air conditi...

NSK’s cost saving Asset Improvement Programme has succeeded in solving a recurring problem of large bearing failures in a screw pump conveying system at a major cement works. Because of contamination, 27 bearings in one year were consumed by the screw pump system. NSK has reduced this by over 50% with its solution based on Hi-TF™ bearings, at the same time reducing maintenance costs and improving reliability at the plant.

Steinmeyer, Inc. announced today a new option to its standard line of precision ball screw products – hybrid ball screws using ceramic rolling elements. By using balls manufactured from silicon nitride instead of tool steel, Steinmeyer is able to eliminate micro-welding in the ball nut. The major benefits include longer lifetime, lower friction and less lubricant required.

Microfluidics expert Dolomite is pleased to announce its collaboration with LioniX B.V. Dolomite and LioniX B.V. join forces in the areas of designing, developing and fabricating microfluidic devices and systems which enable them to expand the range of leading-edge customised solutions to their clients.

Optoelectronic systems are being used to an increasing extent in the manufacture of photovoltaic (PV) modules and are helping greatly to increase production efficiency. In particular, laser technology is proving its superiority in processes such as material removal, fusion, soldering, welding and drilling. Lasers have become indispensable tools, especially in the manufacture of thin-layer solar cells. Manufacturers are therefore profiting directl...

SynQor has announced the release of several new DC/DC converters in its InQor product line targeting RF Power Amplifier applications. The IQ24280HEC14 and IQ24280HZC18 offer a nominal 28V output at 400W and 500W respectively, while the IQ24500HEC08 and IQ24500HZC10 offer a nominal 50V output at the same power levels. All devices utilise the industry standard Half Brick pin-out, and are completely encapsulated in a package measuring just 2.49” x...

AVX Corporation has developed a series of thin and thick film resistive products optimized for maximum power handling and low voltage standing wave ratio. The series, which includes high-power resistors, terminations, and attenuators, features power handling from 4W to 800W, and is available in a variety of sizes and termination styles, including flange, leaded, and surface mount.
