Multifunctional Quantum Sensing Using Single Spins in a van der Waals Crystal
The work demonstrates a dual quantum sensing of temperature and magnetic field using spin‐complex quantum emitters in hexagonal boron nitride (hBN). Temperature sensing via zero‐phonon‐line shifts and magnetometry via optically detected magnetic resonances, enable simultaneous local thermometry and magnetic‐field measurements.

Autonomous Solar Metallurgy for High‐Purity Gold Recovery from Electronic Waste
Inspired by microbial strategies for metal uptake and biomineralization, defect‐rich copper sulfide (Cu31S16) functions as a solar metallurgical platform that unifies Au(III) capture, reduction, and self‐separation. The bioinspired design enables ultrafast gold recovery from electronic‐waste leachates and the spontaneous formation of millimeter‐scale ...

Galvanically Isolated Modular Converter
The ever increasing penetration of renewable energy systems in the distribution grids will inevitably require profound changes in the grid infrastructure. One emerging direction, the medium voltage dc (MVdc) grids, is the cornerstone of this work. They are foreseen for offshore wind parks and onshore large scale renewables collection grids, future on ...
