Advanced Science, EarlyView.Two microwave‐assisted synthetic methods, specifically a one‐pot and a seeded‐growth approach, are developed within a hydroalcoholic solution for the growth of single‐phase ternary WxTi1‐xO2 and heterostructured TiO2‐WO3‐x colloidal nanocrystals. Both types of nanocrystals show significant photocatalytic activity for 4‐methoxybenzyl alcohol oxidation ...

Advanced Science, EarlyView.Protease‐activated plasmonic nanosensors are demonstrated to noninvasively monitor antitumor T cell activity in tumors with anatomical information upon adoptive T cell transfer via ultrasound‐guided photoacoustic imaging. These nanosensors are actuated by granzyme B, a protease secreted by activated cytotoxic T cells during tumor cell killing, which ...

Miniature Robotic Swimmer with Precise 2D Motion Control via Acoustic Vortex‐Induced Propulsion
Advanced Science, EarlyView.In this work, a miniature robotic swimmer achieves precise 2D motion using sound waves with customized 3D‐printed lenses. Localized acoustic vortices drive both translation and rotation of the swimmer without mechanical parts. This contactless approach offers a novel route to controlled micro‐scale movement, with promising applications in biomedical ...

Wave‐Partition‐Governed Dual‐Site Spallation in Single Crystals
Advanced Science, EarlyView.Crystalline anisotropy shapes shock‐wave propagation and the resulting damage evolution in single crystals. Large‐scale molecular dynamics and damage modeling uncover a dual‐spallation mechanism driven by anisotropic elasticplastic wave separation, which mitigates damage accumulation.

Advanced Science, EarlyView.This schematic integrates the eight statistically significant causal relationships identified between 1,366 brain imaging‐derived phenotypes (IDPs) and 18 autoimmune inflammatory diseases (AIDs). Arrows indicate the direction of causality inferred from bidirectional two‐sample MR analyses.
