Electronic Conductivity as a Rate‑Limiting Factor for Calcium‑Ion Storage in Layered Vanadium Oxides

ABSTRACT Rechargeable calcium batteries are promising for sustainable energy storage but lack cathode materials that reversibly intercalate Ca 2+ at practical rates. While considerable efforts have focused on improving ionic conductivity, this work investigates how electronic con...

Solar‐Driven Photothermal Manufacturing of Defect‐Rich Oxide Interfaces for Biomass Electrocatalysis

ABSTRACT Defect‐rich metal oxides are central to sustainable electrocatalysis, yet conventional heat treatment is generally constrained by thermodynamic equilibrium, limiting precise control over defect chemistry while requiring substantial energy input. Here, we establish a sola...

A Dual-Criterion System for Surface-Localized States Identification: Application to Al(001) Surface

Angle-resolved photoemission spectroscopy (ARPES) clearly resolves surface-localized (SL) states, yet conventional density functional theory (DFT) band structures from slab calculations do not readily distinguish weakly confined SL states on surfaces such as Al(001), as tradition...

A ComplexSpin-Transition Thermal Hysteresis Unlockedby Two Competing Symmetry-Breakings

Abstract The spin-crossover material [Fe(NH2trz)3](NO3)2 belongs to the class of 1D triazole-based polymeric SCO complexes. It exhibits a thermal phase transition, with a 28 K wide thermal hysteresis, characterized by phase transition temperatures T↑ = 346 K upon warming and T↓ =...

Tetraniline-Engineered Nickel Molecular Frameworks for Combinatorial NIR-Triggered Photothermal and Photodynamic Cancer Therapy

Near-infrared (NIR)-responsive nanomaterials are of critical importance for biomedical applications owing to their superior tissue penetration depths. Herein, we present a rational design of NIR-responsive tetraniline (TANI)-engineered nickel coordination frameworks for multimoda...
