An N‐doped carbon‐confined Bi/Bi2O3 heterostructure enables ultrafast and reversible Bi0/Bi3+ phase conversion through heterointerface seeding. The pre‐established Bi/Bi2O3 interfaces provide nucleation‐active sites for heterophase regrowth, while the N‐C shell promotes electron transport and structural stability, overcoming kinetic limitations in ...

A scalable synthesis of carbon‐supported ultrasmall CeO2 nanoparticles with precisely tunable Ce electron density is reported. Electron‐lean Ce sites activate H2O2 exclusively via a nonradical pathway, enabling efficient HOBr and 1O2 production analogous to bromoperoxidase for contaminant and antibiotic resistance removal.

A charge‐transfer‐engineered Ni catalyst derived from an atomically mixed layered precursor enables efficient ammonia‐to‐hydrogen conversion. Cr‐to‐Ni electron transfer creates electron‐rich Ni active sites that favor NH3 adsorption, modify the dehydrogenation energetics, and weaken N2 binding to facilitate product desorption. This electronically tuned

Improved Deformability of Co‐Free Medium Entropy Oxides by Controlled Entropy Destabilization
Controlled entropy destabilization activates defect‐mediated plasticity in Co‐free (CuMgNiZn)O by promoting pre‐existing Cu‐rich secondary phases that serve as defect sources. Temperature‐dependent dislocation activity evolves from limited motion at room temperature to extensive glide and stacking‐fault formation at 600 °C, enabling improved plasticity

Porcupine‐Quill‐Inspired Shape‐Morphing Biointerfaces Disassemble Biofilms
A porcupine‐spine‐inspired dynamic offensive bio‐interface is developed for active biofilm disassembly. By coupling electrically driven nano‐dagger penetration with light‐triggered ROS generation, the surface overcomes the passive limitations of conventional mechano‐bactericidal topographies, achieving near‐complete biofilm eradication, strong ...

Data arc presented showing the changes in physical properties which occur during the calcination of Bayer-process gibbsite at temperatures up to 1400°C. The various stages of the calcination were examined using differential thermal analysis, X-ray diffraction, low-temperature nitrogen adsorption, optical and electron microscopy, and particle-size ...

During iron phosphate regeneration, sequential washing distinguishes lithium fractions by accessibility: approximately 70% of precipitate‐associated lithium is washing‐removable, while approximately 30% remains after three cycles. Comparisons of simulated and practical systems associate retained lithium with hydrated amorphous Fe‐O‐P environments ...
