A family of high-power resistors has been added to the New Yorker Electronics passive component portfolio. The Vishay Dale Thin Film PCAN Series of resistor are built on aluminum nitride substrates, and offer power ratings to 6W and resistance from 2Ω to 30kΩ in 1206 and 2512 case sizes. They are optimised as snubber circuits and burden, gate load and amplifier termination resistors in industrial, military and medical applications.

A group of scientists from Hong Kong University of Science and Technology; the University of California, Santa Barbara; Sandia National Laboratories and Harvard University were able to fabricate tiny lasers directly on silicon—a huge breakthrough for the semiconductor industry and well beyond. For more than 30 years, the crystal lattice of silicon and of typical laser materials could not match up, making it impossible to integrate the two m...

To improve the efficiency of waveguides, a complex balance must be struck. The need for enhanced optical signal processing properties competes with the demand for low optical losses in waveguide material. Now, A*STAR researchers have developed an alloy that fits the bill, while achieving compatibility with existing silicon computer chip fabrication technology.

Terahertz spectroscopy, which uses the band of electromagnetic radiation between microwaves and infrared light, is a promising security technology because it can extract the spectroscopic "fingerprints" of a wide range of materials, including chemicals used in explosives. But traditional terahertz spectroscopy requires a radiation source that's heavy and about the size of a large suitcase, and it takes 15 to 30 minutes to analyse a single sample,...

Scientists have developed a type of graphene-based transistor and using modelling they have demonstrated that it has ultralow power consumption compared with other similar transistor devices. The findings have been published in a paper in the journal Scientific Reports. The most important effect of reducing power consumption is that it enables the clock speed of processors to be increased. According to calculations, the increase could be as high ...

Successfully scaling up an R&D team is a challenge, the amount of information and data from machines, planned and executed experiments and result analysis increases very rapidly as more people become involved. To efficiently coordinate workflows, and to reduce the time needed to integrate new knowledge into the production chain, it is important to invest in the structured dissemination and automation of results, documentation and core knowled...

Some adhesives may soon have a metallic sheen and be particularly easy to unstick. Researchers at the Max Planck Institute for Intelligent Systems in Stuttgart are suggesting gallium as just such a reversible adhesive. By inducing slight changes in temperature, they can control whether a layer of gallium sticks or not. This is based on the fact that gallium transitions from a solid state to a liquid state at around 30ºC.

The PCIM Europe 2016 exhibition taking place in Nuremburg in May, will see Panasonic introduce a range of technologies, from the new X-GaN gate driver, the LDPGS thermal management solution, new power choke coils in 12x12 case size for high current automotive applications, as well as the latest capacitors and resistors for high power applications.

Electronic materials have been a major stumbling block for the advance of flexible electronics because existing materials do not function well after breaking and healing. A new electronic material created by an international team, however, can heal all its functions automatically even after breaking multiple times. This material could improve the durability of wearable electronics.

Since the last Farnborough Airshow in 2014, the Wallwork Group has invested an additional £2.5m in buildings, plant, training and research to extend and deepen services for the aerospace industry. The company has also gained more aerospace approvals for processes at all their UK sites to ensure a national service with assured quality and quick turnaround.
