Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays

Advanced Functional Materials, EarlyView.
Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

Selenium‐Integrated Cyanine Dye With Enhanced Photophysical Properties for Optoacoustic‐Guided Cancer Imaging and Therapy

Advanced Functional Materials, EarlyView.
This study introduces selenium‐integrated cyanine dye (Se‐Cyn), with superior photostability, absorption, and photothermal efficiency, outperforming ICG in NIR window. Its nanoparticle form remains stable in water, accumulates in tumors, and enables strong optoacoustic imaging and effective phototherapy outcomes.

Investigation of acoustic and geometric effects on the sonoreactor performance

Ultrasonics Sonochemistry, 2020
In this work, three design configurations of a sonoreactor are considered under various operating conditions, and the acoustic characteristics during water sonication are investigated while using an immersed-type ultrasonic flat transducer probe in a sonoreactor model. Numerical models are also developed to simulate the sonication process, and they are

Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

Advanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a
