Abstract With the significant development of technologies based on dielectrophoretic or acoustophoretic forces, the dynamic visualization of these forces is important. Here, we present an electroluminescent display that enables comparative visualization of dielectrophoretic and acoustophoretic forces. Our display utilizes alternating current-driven electroluminescence in combination with conductive microparticle self-assembly controlled by dielectrophoretic and acoustophoretic forces.

Abstract Perovskite-based solar water splitting systems are promising candidates for addressing environmental challenges, exceeding the commercialization efficiency of solar-to-hydrogen (STH) at >10%. However, the operational stability remains suboptimal due to insufficient in situ/operando insights into charge carrier dynamics.

Abstract To build in vitro tissues for therapeutic applications, it is essential to replicate the spatial distribution of cells that occurs during morphogenesis in vivo. However, it remains technically challenging to simultaneously regulate the geometric alignment and aggregation of cells during tissue fabrication.
