Super‐Resolution Ultrasound Based Cell Tracking With Polymeric Nanobubbles
Advanced Materials, EarlyView.This study presents a super‐resolution ultrasound platform for tracking cells in vivo. Biocompatible polymeric nanobubbles are used as highly echogenic intracellular labels. Following the injection of cells and microbubbles, ultrasound localization microscopy (ULM) can dynamically match the microvascular architecture and individual cell trajectories ...

Advanced Materials, EarlyView.Flexible neutral Zn‐air batteries achieving a remarkable 3000‐cycle lifespan and withstanding 1000 bending cycles are reported. This performance is realized by employing a 3D physically cross‐linked neutral hydrogel electrolyte that integrates high adhesion, self‐healing, O2 permeability, and CO2 tolerance to resolve critical stability challenges ...

Influence of gas hydrate dissociation on mechanical properties of gas hydrate-bearing sediment
, 2015 Gas hydrate dissociation in marine sediments will cause increase of excess pore pressure, loss of soil particle cementation and breakdown of soil structure, which may result in large deformations of the strata and offshore structure foundations. Based on

Advanced Materials, EarlyView.This project developed a smart bandage‐like patch (a microneedle array) for repairing diabetic bone damage. It intelligently senses signals from infection and inflammation, then releases its medicines in a specific, timed sequence: first an antibacterial agent, then an anti‐inflammatory agent, and finally growth factors.

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells
Advanced Materials Interfaces, EarlyView.Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.
