When lithium-ion batteries are charged too quickly, metallic lithium gets deposited on the anodes. This reduces battery capacity and lifespan and can even destroy the batteries. Scientists at the Technical University of Munich (TUM) and the Forschungszentrum Jülich have now presented a process that, for the first time ever, allows this so-called lithium plating ...

Imec has produced the first power-performance-area-cost (PPAC) analysis of different sequential 3D-integration variants using advanced 5nm and 3nm CMOS technology nodes. The most significant benefit was found for a heterogeneous sequential-3D integration approach that uses different device layers (or tiers) for the non-scalable (analog and I/O) and scalable parts (logic and memory) of the system. ...

Leti has integrated hybrid III-V silicon lasers on 200mm wafers using standard CMOS process flow. This shows the way to transitioning away from 100mm wafers and a process based on bulk III-V technology that requires contacts with noble metals and lift-off based patterning. The project, carried out in the framework of the IRT Nanoelec ...

TI has introduced an op amp which, it claims, is the first to combine ultra-high precision with the industry’s lowest supply current. “With exceptional power-to-precision performance, the LPV821 zero-drift, nanopower op amp enables engineers to attain the highest DC precision, while consuming 60 percent less power than competitive zero-drift devices.,” says TI. The LPV821 is ...

Historic events make a Major League Baseball (MLB) season memorable. Last month, for instance, the Houston Astros won its first World Series championship ever. Several months before that, however, a less-well-known event took place: MLB approved the use of any Whoop Inc. wearable fitness tracker by all players and coaches in games.
Artificial intelligence has been used crack one of the codes originally deciphered in the 1940s at Bletchley Park. It took just 13 minutes and cost £10. And involved a computer recognise German, from a standing start. A company called Enigma Pattern did it by combining machine learning and artificial intelligence, running its algorithms on cloud servers ...

LEDs can replace mass-market high power UV light sources, according to a German research team coordinated by Osram. The optical outputs are expected to be: >20mW at 300±10nm >140mW at 280±10nm >80mW at 260±10nm One of the project aims is to make sources that are sufficiently long-lived to replace mercury-based sources in production, disinfection, life ...
