Policing on-line hate from within a single platform, such as Facebook, can make the spread of hate worse, and will eventually generate global ‘dark pools’ in which hate will flourish, is one of the findings the finding in a recent scientific paper in Nature. The paper was written after analysis using a “first of its ...

Micromachining can be used to create a infra-red beam-forming phased array, according to engineers at Berkeley University of California who have made a 160 x 160 array on a 3.1 x 3.2mm die that can be switched in 5.7μs (resonance is at 55kHz). “It is capable of providing about 25,600 rapidly steerable spots within its ...

Power Integrations is aiming at larger home appliances needing to meet IEC60335 with an X-capacitor discharger that can empty 6µF in under a second. X-capacitors are part of the EMC input filter of power supplies (see diagram right), that are essentially connected directly to the appliance’s mains plug and, uncontrolled, are left with up to ...

At the end of July, Power Integrations revealed that it has been quietly using GaN power transistors in some of its products for months. This followed the work of analyst TechInsights, which de-capped an InnoSwitch3 IC from the PI and found a GaN part inside. Shortly after this, now armed with the correct search terms, it became ...

Metal film features from 1μm to 10cm across can be formed by a process developed at the University of Warwick, which exploits the characteristics of a cheap organofluorine compound, and needs no toxic chemicals. It is a vacuum deposition process that works with copper and silver, and exploits the different ‘condensation coefficient’ (‘C’) of two materials. ...
