Operando Electrochemical Formation of Integrated Ni‐Fe Oxyhydroxide Anode for Durable Anion Exchange Membrane Water Electrolyzer

Advanced Science, EarlyView.
The interfacial stability and activity of Ni‐Fe‐based AEMWE anodes can be directly enhanced by operando voltage‐cycling in a FeOOH‐containing electrolyte. This process simultaneously induces Ni oxidation and Fe incorporation, forming an integrated, porous (Fe, Ni)OOH layer with high conductivity and durability.

Intercalibration 8802 (ICP Waters report)

, 1988
Ten laboratories in nine countries participated in the second intercalibration, 8802. Based on the general target accuracies of 20%, all the results were acceptable for conductivity, nitrate, sulfate and sodium. For chloride, calcium, magnesium and potassium, one or two laboratories have reported results outside the general limit.

Epitaxial Stabilization of Ultrasmall Cu Nanoparticles With High‐Energy {110} Facets on Ti3C2 MXene for Efficient CO2‐to‐Acetate Electrocatalysis

Advanced Science, EarlyView.
Cu/Ti3C2 heterostructure: Cu/Ti3C2 heterostructure achieves epitaxial stabilization of high‐energy Cu(110) facets through lattice matching and electronic interaction, enabling efficient CO2 electroreduction to acetate with 42.5% Faradaic efficiency at 235 mA·cm−2. ABSTRACT The electrochemical CO2 reduction reaction (CO2RR) to multicarbon (C2+) products

Multifunctional Eutectic Mixtures Enable Integrated Recovery of U, Pu, and Sr From Nuclear Waste

Advanced Science, EarlyView.
A novel class of multifunctional eutectic mixtures, crafted from crown ether and organophosphorus molecules, achieves highly efficient, simultaneous recovery of uranium, plutonium, and strontium from nuclear waste. The material operates via a dual “coordination‐encapsulation” mechanism within self‐assembled reverse‐micelle structures, offering a ...

Reinforcing Oxygen Activation of Spinel Oxide via Mn─O Covalency Engineering for VOCs Oxidation

Advanced Science, EarlyView.
A MnCo spinel catalyst with weakened Mn─O covalency was synthesized via a hard‐template method. The reduced Mn─O covalency facilitates localized electron redistribution, promoting the activation of both molecular oxygen and lattice oxygen, and thereby enabling the efficient and complete oxidation of VOCs (ethyl acetate, toluene, and propane).
