Isotopic Engineering of Water Reactivity for Stable Aqueous Iron‐Metal Batteries

Jiahao Li, Simil Thomas, Xin Liu, Fangwang Ming et autres

ABSTRACT The development of aqueous iron‐metal batteries (AIBs) is critically hindered by the severe parasitic hydrogen evolution reaction (HER) at the anodes and the resulting structural degradation of the cathode. Moving beyond conventional additive‐based approaches, this work presents a kinetically targeted strategy …

Enhanced Contribution of Biexciton‐Mediated Decay Kinetics in Perovskite Nanocrystals Via Sequential Ultrafast Excitation

Lijie Wang, Renqian Zhou, Malte Oppermann, X X Zhang et autres

Controlling the temporal and kinetic statistics of excitons in semiconductor nanocrystals is important for understanding how multiexcitonic processes emerge in ultrafast excited‐state dynamics under low‐fluence conditions. Under conventional single‐pulse excitation, the Poissonian nature of exciton generation limits the manifestation of biexciton‐mediated processes …
