Advanced Materials Technologies, EarlyView.This work demonstrates fluidic self‐assembly and self‐alignment of flip‐chips using a magnetic field for agitation and orientation. Pb‐free solder bumps with tailored transformation imprinted melting points enable selective capturing on low‐melting solder in water. After capturing, final alignment is achieved through magnetic forces.

Advanced Materials Technologies, EarlyView.A flexible, lightweight ankle brace made from 3D‐printed liquid crystal polymer metamaterials offers targeted support without restricting movement. Programmable stiffness provides protection during risky motions. Biomechanical tests suggest performance comparable to commercial braces with reduced bulk, highlighting potential for broader orthotic ...

Driving Micro‐Objects Using Optical Force due to Fluorescence Emission From Molecules
Advanced Optical Materials, EarlyView.Emission of fluorescence from a micro‐object in a specific direction is expected to generate an optical force driving the object in the opposite direction of the emission, like a rocket. To demonstrate this ‘photon‐driven micro‐rocket’, we prepared dye‐doped polymer micro‐object (PMO) one surface of which was covered with metallic film; the PMO ...

Advanced Science, EarlyView.Human skin inherently forms a body‐coupled triboelectric circuit that enables the generation of triboelectric charges through contact between the skin surface and various materials. Integrated with an on‐finger, substrate‐free microfiber electrode, the material‐specific and personalized triboelectric signals can be imperceptibly collected for machine ...

A Nanostructured Ru‐Mn‐Nb Alloy with Oxygen‐Enriched Boundaries for Ampere‐Level Hydrogen Evolution
Advanced Science, EarlyView.Ru62Mn12Nb21O5 medium‐entropy alloy with a crystal‐crystal dual‐phase structure is deposited on a carbon cloth substrate by the magnetron sputtering method. The oxygen‐rich interface induced by the rich Mn phase and the poor Mn phase optimized the electronic structure of the catalyst, adjusted the adsorption and desorption processes of intermediates ...

Advanced Science, EarlyView.YxMnyOx+2y catalyst provides dual active sites of Lewis acid (Y3+) and Mn for the co‐adsorption of H2O and O3, and the fast dissociation of adsorbed H2O to surface *OH. Then, a newly OH‐accompanied pathway for O3 decomposition is formed, transforming H2O to active ·OH radical, with the assistance of high energy electrons in the plasma.
