Electric‐Current‐Assisted Nucleation of Zero‐Field Hopfion Rings

Advanced Materials, EarlyView.
This work reports a novel and efficient nucleation protocol for 3D localized topological magnetic solitons‐hopfion rings in chiral magnets using pulsed electric currents. By using Lorentz transmission electron microscopy and topological analysis, we report characteristic features and extraordinary stability of hopfion rings in zero or inverted external

High‐Density Topological Defect Array by Two‐Step Interference Photoalignment

Advanced Materials, EarlyView.
High density arrays of topological defects in nematic liquid crystal are realized by two‐step interference photoalignment, with a minimal distance of 1.25 micrometer and disclination lines connecting defects on opposing substrates. Such layers can be used as reconfigurable templates for photonic devices to achieve large angle diffraction, beam shaping ...

Laser‐Synthesized Amorphous PdSe2‐x Nanoparticles: A Defect‐Rich Platform for High‐Efficiency SERS, Photocatalysis, and Photothermal Conversion

Advanced Materials Interfaces, EarlyView.
Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to

Ultrafast Photocatalytic Wettability Switching in Substrate‐Interface Tailored Titanium Dioxide Thin Films

Advanced Materials Interfaces, EarlyView.
This study demonstrates ultrafast photocatalytic wettability switching in TiO2 thin films by tailoring substrate doping and interface oxides. Enhanced switching rates and hemiwicking effects are achieved through optimized material stacks and nanostructuring.

NIR‐Activated Ag2S Quantum Dots for Efficient Broad‐Spectrum Antibacterial and Biofilm Disruption

Advanced Materials Interfaces, EarlyView.
This study presents a novel non‐antibiotic strategy leveraging NIR‐activated Ag2S QDs for synergistic PTT/PDT. The platform degrades the protective extracellular matrix via localized hyperthermia, facilitating deep penetration and ROS‐induced oxidative damage.

Multifunctional Oxadiazole‐Based Polycatenars: A Pathway to Polar Columnar Phases

Advanced Materials Interfaces, EarlyView.
Aromatic core fluorination directs oxadiazole‐based polycatenars into ferroelectric and antiferroelectric columnar phases with supergelation and photo‐responsiveness. ABSTRACT Polar columnar liquid crystals (LCs) offer a promising pathway to nanostructured architectures for next‐generation ferroelectric devices.
