Small, EarlyView.The AC‐TDS enables precise hydrogen isotope analysis over a wide temperature range (15–900 K), allowing both physisorption and chemisorption processes to be investigated under gas exposure conditions. Through calibration, this system achieves reliable quantitative desorption analysis, including direct quantification of H2, D2, and HD under mixed ...

Intraparticular Heterogeneity Limits Capacity in Lithium–Sulfur Batteries With Carbonate Electrolyte
Battery Energy, Volume 5, Issue 3, May 2026.Cryo‐electron‐microscopy and electrochemical testing reveal that the cathode‐electrolyte interphase in Li–S batteries with carbonate electrolytes forms heterogeneously across carbon particles. This intraparticle heterogeneity limits capacity and rate performance, highlighting the critical role of particle size and cathode‐electrolyte interphase ...
