Influence of Micropillar Height Modulation on Droplet Evaporation and Wetting State Transitions
Controlling droplet evaporation dynamics is crucial across many fields. Here, it demonstrates laser‐fabricated polymer micropillar arrays with tailored height variations to regulate evaporation behavior. While all arrays exhibit superhydrophobic wetting, their distinct height profiles effectively slow evaporation and alter evaporation modes ...

An intentionally added, chemically formed LixAlSy coating stabilizes the lithium–electrolyte interface in solid‐state Li–S batteries. The layer suppresses side reactions, preserves smooth charge transfer, and improves ion transport from the start. This approach offers a practical route to more durable solid‐state batteries and a clearer understanding ...

Loading Mode Dependence of Twin‐Twin Boundary Formation in a Textured Magnesium Alloy
The structures of twin‐twin boundaries formed by interactions between twin variants sharing the same or different zone axes in a deformed magnesium alloy are demonstrated. Lattice distortion around complicated interfaces promotes grain refinement in the subsequent thermomechanical process, enhancing the mechanical performance of magnesium alloys ...
