Decoupling the Impact of Deep‐Trap and Band‐Tail States on PbS Quantum Dot Photodetectors via Alkylamine Engineering

Advanced Materials Technologies, EarlyView.
Band‐tail and deep trap states are effectively disentangled through the use of selective alkylamine additives. PA‐driven 2D ordering narrows band tails, while HA enhances halide passivation and Pb coordination to suppress deep traps. A comparative study of their CQD short‐wave infrared (SWIR) photodetectors further reveals whether band‐tail states or ...

All Solid Lithium Metal‐Polymer Battery End‐of‐Life: an Investigation of Symmetric, Battery, and Bilayer Cells

Advanced Science, EarlyView.
In this study, the evolution of the lithium (Li)/polymer interface is compared in a realistic pouch cell configuration, either in Li/Li symmetric cell or in full Li/LiFePO4${\rm LiFePO}_4$ batteries thanks to X‐ray micro‐tomography. While Li/Li symmetric cells are the reference cell for probing the interface stability, results demonstrated that the end‐

Synergistic Modulation of Ru–O Bond Covalency via Ba/Fe Co‐Doping and Oxygen‐Vacancy Engineering for Efficient Wide‐pH Oxygen Evolution

Advanced Science, EarlyView.
Ba/Fe co‐doping and oxygen vacancy engineering synergistically modulate the Ru–O bond covalency in RuO2, leading to markedly enhanced OER activity across wide‐pH electrolytes. ABSTRACT Developing efficient and stable oxygen evolution reaction (OER) catalysts across a wide‐pH range is critical for practical water electrolysis.
