Polarization‐Enabled Piezoelectric Tellurium–Selenium (TexSe1–x) Thin Films for Memory Switching and Artificial Synaptic Functions

Advanced Science, EarlyView.
Here, we demonstrate and investigate polarization‐enabled electromechanical responses in cryogenic physical vapor deposition (cryogenic PVD)‐deposited TexSe1‐x thin films, a tellurium‐based compound with a tunable bandgap and enhanced non‐centrosymmetry.

Oxidative uptake of Ce by oceanic ferromanganese crusts and implications for paleoredox estimates using Ce isotopes

Communications Earth & Environment
The oxidative enrichment and isotopic fractionation of cerium (Ce) in contact with vernadite (δ-MnO2) serve as a proxy for past redox conditions in both terrestrial and marine environments.

The Third‐Generation Magnetic Super‐Stable Mineralizer: Complete Removal and Separation of Multiple Heavy Metal Pollutants

Advanced Science, EarlyView.
The 3rd‐generation magnetic super‐stable mineralizer M‐MgAl‐700 features a core‐shell structure, strong superparamagnetism, large surface area, and abundant oxygen defects. It achieves exceptional Cd(II) and As(V) mineralization capacities, reducing both pollutants in co‐contaminated water and soil to meet national standards.

Zero Thermal Expansion and Local Structure in KxMnxFe2‐xMo3O12‐Based Materials

Advanced Science, EarlyView.
Local structure engineering via ion insertion drives local structural transformation from low‐symmetry P21/a to high‐symmetry R‐3c, enhancing structural flexibility and realizing a transition from positive thermal expansion to wide‐temperature‐range zero thermal expansion in KxMnxFe2‐xMo3O12‐based materials.

Interfacial Polysulfide Confinement via Spatially Controlled Sulfonated Metal–Organic Polyhedra Coatings in Lithium–Sulfur Batteries

Advanced Science, EarlyView.
Spatially controlled sulfonated metal–organic polyhedra (SMOP) coating on sulfur‐loaded hollow carbon spheres form ultrathin, conformal interfacial barriers that selectively confine soluble polysulfides, stabilize sulfur redox, and suppress shuttle reactions.

Reaction‐Induced Reversible Reconstruction Enhanced Ni‐MgO/CaO Dual Functional Material for Stable CO2 Capture and In Situ Conversion

Advanced Science, EarlyView.
A highly dispersed NiO‐MgO solid solution (MgxNi1‐xO) is created in a hierarchically porous Ca‐based matrix to protect Ni and CaO nanoparticles against carbon deposition and sintering. Owing to the reversible reconstruction of MgxNi1‐xO, this superior structure is self‐regenerative in the calcium looping dry reforming of methane process, thereby ...

Electric‐Current‐Induced Phase Transformation in Cu6Sn5 Below Its Equilibrium Transition Temperature

Advanced Science, EarlyView.
Electric current induces a monoclinic‐to‐hexagonal phase transformation in Cu6Sn5 at a measured bulk temperature of ∼120°C, below the equilibrium transition temperature. Ex situ synchrotron x‐ray diffraction, TEM, and matched thermal controls show that current stressing promotes the formation of a retained hexagonal η‐phase post‐stress state not ...

Hydrothermal Embedding of Pd Single Atoms Into SnO2 for Efficient CO Oxidation

Advanced Science, EarlyView.
By applying hydrothermal regulation to SnO2‐supported PdO, we achieve atomic dispersion of Pd into the SnO2 lattice, which activates the lattice oxygen neighboring Pd atoms to generate oxygen vacancies and facilitates subsequent O2 activation, thereby promoting CO oxidation to proceed via a low‐energy‐barrier MvK pathway while avoiding CO poisoning ...
