Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing

Advanced Materials, EarlyView.
Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.

Advanced Separators for Liquid and Quasi‐Solid Lithium Rechargeable Batteries: Design and Development

Advanced Materials, EarlyView.
This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...

Plasmonic Nanomachines: Creating Local Potential Gradients and Motions

Advanced Materials, EarlyView.
Plasmonic nanomachines can generate optical, thermal, and chemical potential gradients to drive directional rectilinear, rotational, and twisting motions at the nanometer scale. The integration of multimodal plasmonic forces with functional materials and programmed structural distortions enables precise spatiotemporal actuation, thereby providing a ...

Integrating ZnO/Ag2O@g‐C3N4‐Based Nanocomposites Into a Carrageenan Matrix to Efficiently Remove Heavy Metals From Water

Advanced Materials Interfaces, EarlyView.
ABSTRACT This research focused on characterizing graphitic carbon nitride (g‐C3N4) nanocomposites incorporated with ZnO and Ag2O nanoparticles, and carrageenan to remove heavy metals. The ZnO/Ag2O@ g‐C3N4 and ZnO/Ag2O/g‐C3N4@Carr nanocomposites demonstrated thermal stability of 97.40% (108.81°C) and 82.80% (188.99°C) for TGA.
