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.

Optimization Design of Phased Array Ultrasonic Transducer Arrays
DEStech Transactions on Computer Science and Engineering, 2018 The design and selection of the transducer array parameters directly affect the performance of the audio directional transmission system. In this paper, the influence of the number of array element, the pitch, the frequency and the deflection angle on the array directivity is analyzed in detail.

Advanced Materials, EarlyView.A reversible, all‐optical modulation strategy enables resist‐free, sub‐diffraction nanolithography of halide perovskite films. Leveraging 800 nm fs laser‐induced crystallization and 365 nm laser driven decomposition, reconfigurable patterning achieves feature sizes down to 93.5 nm. This chemistry‐free approach offers dynamic control over optoelectronic
