Heat provides a simple way to separate entangled electrons for research

The thermoelectric effect can be used to produce entangle photons, according to scientists from Finland, Russia, China and the USA. The proof-of-concept device is superconducting and has layered graphene (green) and metal (blue) electrodes on a silicon dioxide substrate (grey). “Superconductivity is caused by entangled pairs of electrons called Cooper pairs,” said Nikita Kirsanov of Aalto ...

Viewpoint: Reliability, and Bluetooth overcoming interference with AFH

Martin Woolley, Senior Developer Relations Manager, EMEA, at Bluetooth SIG, considers how Bluetooth technology operates to mitigate interference and increase reliability, with adaptive frequency hopping (AFH). Wireless communication systems usually employ radio as the underlying, physical basis for getting data from one device to another. Bluetooth itself is a radio communications technology. But there’s a ...

DIN rail controller for uninterruptible 24V power supply

German PSU maker Puls Power has announced a 40A-rated DIN-rail-mounted controller for uninterruptible power supply systems. Called UB40.241, it doubles current capacity compared with the company’s earlier top-end model. The controller mediates between an external 24Vdc power supply (±25%) and external battery pack to bridge power failures and voltage fluctuations by charging the battery when system ...
