Scientists at the University of Chicago and Argonne National Laboratory have discovered a new way to precisely pattern nanomaterials that could open a new path to the next generation of everyday electronic devices.The new research, published inScience, is expected to make such materials easily available for eventual use in everything from LED displays to cellular phones to photodetectors and solar cells.

Instant and accurate man overboard location is just one of many features that SCADA technology is offering to transform the safety and comfort of pleasure sailing. Products4Automation’s SCADA expert Paul Hurst casts an over of the technology transfer from industrial process plant to luxury yacht.

Anyone who has a rear-view mirror that automatically dims blue in reaction to annoying high-beam headlights glaring from behind has seen an electrochromic film in action.Now, chemists at the Georgia Institute of Technology have developed a new method to more safely and, by extension, easily produce these shear films, which change their colour with the help of a tiny electric current. This could make them available to many industries that have not...

A complete lithium-ion battery backup management system for 3.45-4.45V supply rails that must be kept active during a long duration main power failure has been introduced byAnalog Devices, which recently acquired Linear Technology. The LTC4091 employs a 36V monolithic buck converter with adaptive output control to provide power to a system load and enable high efficiency battery charging from the buck output.

The next generation of feature-filled and energy-efficient electronics will require computer chips just a few atoms thick. For all its positive attributes, trusty silicon can’t take us to these ultrathin extremes.Now, electrical engineers at Stanford have identified two semiconductors – hafnium diselenide and zirconium diselenide – that share or even exceed some of silicon’s desirable traits, starting with the fact that al...

Supplier of RF power transistors,NXP Semiconductors, has announced what it claims to be the industry’s highest power transistor for 915MHz applications. The MRF13750H transistor delivers 750W continuous wave (CW), 50% higher than comparable products currently available on the market. Based on 50V silicon LDMOS, this transistor extends the limits of solid-state RF generation, making the MRF13750H an alternative to vacuum tubes for very high ...

A demonstration kit from Efficient Power Conversion (EPC) targets Class 4 AirFuel Alliance-compatible wireless power for wireless charging and is based on the company's eGaN FETs.

GaN Systems is doing anything but slow down this summer, as after APEC and PCIM, power engineers continue to be inundated with GaN product and industry developments.The number of application articles published about GaN transistors is increasing rather than waning.

Solid state imaging technologies have revolutionised medical imaging equipment from X-ray machines to ultrasonic scanners, writes Sally Ward-Foxton.

In 2016, Yole Développement’s analysts said that the SiC power business is concrete and real, with a promising outlook. The trend has not changed in 2017; in fact the SiC industry is going further. Therefore, end users are trying SiC and building prototypes for concrete and promising projects.Dr Hong Lin, Technology & Market Analyst at Yole Développement (Yole), commented:“SiC technology’s added value is today ...
