Flexible Optoelectronic Hybrid Microfiber Long‐period Grating Multimodal Sensor
An entirely new optoelectronic hybrid multimodal optical fiber sensor which can simultaneously monitor biomechanics and glucose is demonstrated. The developed method simultaneously integrates two heterogeneous sensing mechanisms, optical and electrical, into a single sensor in a compact manner. Optical and electrical sensors can work simultaneously but

A straightforward method is introduced to produce ion‐gel films with very low surface roughness by employing a solution‐shearing coating process. These ion‐gel films permit the growth of crystalline thin films of various small molecule organic semiconductor molecules directly on top of the ion‐gel layer, thereby enabling “inverted” small molecule ...

A novel room‐temperature processable stretchable conductor is developed using SBS elastomer, silver fillers, and ionic liquid. This composite solidifies rapidly at room temperature, offering high conductivity and mechanical stability under strain. It enables omni‐directional printing for stretchable circuit fabrication and repair.

Photo‐Thermal Approaches on Polyimide Film for Demonstration of Sub‐50 µm Polymer Stencil Mask
A photo‑thermal approach enables precise control of polyimide film properties during UV laser processing, achieving stencil mask fabrication with feature dimensions <50 µm—with the smallest features measuring 42.4 µm. This method maintains the polymer in its glassy state during processing, resulting in exceptional pattern stability and reproducibility.

Intensification of Alkaline Electrolyzer with Improved Two‑Phase Flow
Porous nickel‐type electrodes with low tortuosity are fabricated and their role in reducing the capillary pressure, bubble point, and ohmic resistance, which led to lower energy loss and higher current densities and efficiencies is investigated. The cell delivers a current density of 2 A cm−2 at ≈2 V.

Sustainable Recovery and Reuse of Hard Carbon From Scrap and End‐of‐Life Sodium‐Ion Batteries
As sodium‐ion battery (SIB) technology advances, sustainable end‐of‐life recycling is crucial. This study presents a direct recycling method for hard carbon (HC) using low‐temperature binder negation at 300 °C under nitrogen. Retaining structural integrity, recycled HC achieves 86–89% capacity retention over 200 cycles.
