A new and more efficient way of modelling and designing power electronic converters using artificial intelligence (AI) has been created by a team of experts from Cardiff University and the Compound Semiconductor Applications (CSA) Catapult. The method has reduced design times for technology by up to 78% compared to traditional approaches and was used to create a device with an efficiency of over 98%.

Throughout history, alchemists believed in the existence of the philosopher's stone: a substance that could turn cheap substances into precious gold. Now scientists from The University of Manchester, Tsinghua University in China and the Chinese Academy of Sciences have shown that graphene can be a kind of philosopher's stone, allowing gold extraction from waste containing only trace amounts of gold (down to billionth of a percent).

A new form of flexible photodetector could provide future robots with an electronic skin capable of 'seeing' light beyond the range of human vision. A team of engineers from the University of Glasgow are behind the breakthrough development, which involves a newly-developed method of printing microscale semiconductors made from gallium arsenide onto a flexible plastic surface.
