US researchers have created a non-natural material that could improve heat extraction from semiconductors, and is the first of a previously-predicted class of high thermal conductivity materials. If it could be made to exist, boron arsenide with a cubic crystal structure was calculated to have a high thermal conductivity – and now it has been made, ...

Japanese researchers have found a new spin on the old themo-electric generator game of minimising thermal conductivity while maximising output power, achieving of 12μW/cm2 from a thermal difference of only 5ºC. From Waseda, Osaka and Shizuoka Universities, the team has turned to a novel arrangement silicon nano-wires. “Due to advantages such as its relatively low thermal conductance but ...

MediaTek has selected luton-based Anritsu’s MT8000A radio communication test station to verify MediaTek’s 5G NR mobile communication base-band chip-set. It will be used from early phase pre-silicon verification through to commercial validation of RF, protocol and function for product launch. Anritsu designed its MT8000A to work with wide-band signal processing and beam-forming, supporting sub-6GHz and millimeter-wave ...

If the heatwave is getting you down and you have $300 to spend there’s a wearable personal cooler on the market called Embr Wave. Developed by MIT alumni under a Kickstarter programme, Embr Wave can both warm you and cool you. “It’s a product for people that are too hot or too cold, that offers thermal ...

President Trump’s policy of reducing America’s trade deficit is working, mostly, reports the US Deparment of Commerce. For the third month in a row, America’s trade deficit (goods and services) with the rest of the world shrank by 6.6% in May to $43.05 billion. America’s trade deficit with Japan shrank 12.6% in May from April ...

OMC, the Redruth, Cornwall optoelectronics specialist, has launched a high brightness purple surface-mount LED lamp. The lamp uses OMC’s proprietary Active Diffuser Technology, which is claimed to produce a richer and more efficient output than traditional single-wavelength devices. The lamp is suitable for applications such as backlighting, mood-lighting, displays and status indication on items such as ...
