A Cu target X-ray tube operated at 8 kV and several mA is used to perform systematic measurements of the rate capability of Multi-Wire Proportional Chambers (MWPC), and its dependence on chamber geometry, gas composition and gas gain. We describe the experimental set-up, system calibration and first results. Introduction The CBM TRD is a xenon-based gaseous detector that will perform particle t...

Abstract MXenes, two-dimensional transition metal carbides and nitrides, are promising materials for electrochemical energy storage application due to their redox-active surface flexible interlayer space. Among all reported MXene-based electrodes, some have shown significantly better high-rate capabilities. Hence, it is crucial a systematic understanding on the decisive factors of rate capabili...

High-rate cathode materials for Li-ion batteries require fast Li transport kinetics, which typically rely on topotactic intercalation/de-intercalation because it minimally disrupts pathways. In contrast to this conventional view, here we demonstrate that the rate capability in a Li-rich cation-disordered rocksalt can be significantly improved when reaction is replaced by non-topotactic reaction...
