Alleviating oxygen evolution from Li-excess oxide materials through theory-guided surface protection

open access: yesNature Communications, 2018
Rechargeable Li-ion batteries can show extensive oxygen loss from the cathode material under operating conditions. Here, the authors use high-throughput computational screening to guide the synthesis of a Tantalum-doped Li-excess cathode that ...

An inverse method to fast-track the calculation of phase diagrams for sonoluminescing bubbles

open access: yesUltrasonics Sonochemistry, 2021
A sound driven air bubble can be transformed into an argon bubble emitting light pulses stably. The very foundation to investigate the sonoluminescing bubble is to accurately determine the ambient radius and gas composition in the interior.
