Magnetoelectric Nanoparticle‐Based Wireless Brain–Computer Interface: Underlying Physics and Projected Technology Pathway

Advanced Science, EarlyView.
Magnetoelectric nanoparticles (MENPs) enable fully wireless, minutely invasive neuromodulation, and potentially neural recording, by converting magnetic into electric and, conversely, electric into magnetic fields, respectively, at high spatiotemporal resolution.

Thermal cycling damage of silica refractories for high-temperature thermal energy storage (HT-TES) – Can it be healed?

Open Ceramics
Silica refractories are promising materials for high-temperature thermal energy storage (HT-TES), because they exhibit excellent thermal cycling properties, unless cooled below a critical temperature (usually assumed to be 600 °C).

Multimodal Photoluminescence in Ca₂Nb₂O₇-based Glass–Ceramics

Ceramics
Lanthanide-doped Ca2Nb2O7 offers versatile and tunable luminescence properties. Previous studies have shown that Pr3+-doped and Pr3+/Er3+ co-doped Ca2Nb2O7 ceramics exhibit non-destructive mechanoluminescence, up- and down-conversion luminescence, and ...

Stage‐Adaptive Janus Microneedle System for Redox‐Immune Regulation and Mitochondrial Protection in Infected Diabetic Wound Healing

Advanced Science, EarlyView.
ABSTRACT Infected diabetic wounds are sustained by a vicious cycle of hyperglycemia‐driven bacterial infection, persistent oxidative stress, and excessive inflammation, which collectively disrupt the ordered progression of tissue repair. Here, we engineered a stage‐adaptive Janus microneedle patch (MN‐FeSAC‐PPE) to enable a staged therapeutic process ...

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

Boosting Ferroelectricity: 2D and Polymer Ferroelectric Hybrids Enabling Ambipolar Nonvolatile MoS2 Memory Transistor

Advanced Science, EarlyView.
Two‐dimensional CuInP2S6 nanosheets are incorporated into a P(VDF‐TrFE) matrix to induce polarization‐cooperative ferroelectric coupling. The resulting P(VDF‐TrFE)/CuInP2S6 hybrid film exhibits reinforced ferroelectric ordering and reduced coercive electric fields compared with pristine P(VDF‐TrFE).
