Front Cover: In article number 2100222 by Rachel C. Steinhardt and co-workers, a soft actuation system is described, based on new core-shell thermally-expandable microparticle, made of isobutane core polystyrene shell, linked to photothermal nano-transducer, gold nanoparticles, resulting in core-shell-shell nanohybrid. The particles expand thermal milieus, are able power the movement composite ...

We demonstrate surface acoustic wave (SAW) induced microparticle manipulation in a microstructured disposable glass-polymer composite superstrate, positioned on a piezoelectric substrate with a single, slanted SAW transducer. An excited SAW was coupled from the piezoelectric substrate into the superstrate, which acted as a transversal resonator structure. We show that the energy transmitted int...

The release mechanism of coumarin 102 from a single ODS-silica gel microparticle into the water phase in the presence of Triton X-100 was investigated by confocal fluorescence microspectroscopy combined with the single microparticle injection technique. The release rate significantly depended on the Triton X-100 concentration in the water phase and was not limited by diffusion in the pores of t...

The release of perylene from octadecylsilyl (ODS)-silica gel into water using a nonionic surfactant was kinetically studied by single microparticle injection and absorption microspectroscopy techniques. The release of perylene from the porous microparticles significantly depended on the surfactant concentration. The release rate constant was inversely proportional to the microparticle radius;...

Silicon is widely recognized as one of the most promising anode materials for lithium-ion batteries due to its 10 times higher specific capacity than graphite. Unfortunately, the large volume change of Si materials during their lithiation/delithiation process results in severe pulverization, loss of electrical contact, unstable solid-electrolyte interphase (SEI), and eventual capacity fading. A...

Circulating blood microparticles are submicron vesicles released primarily by megakaryocytes and platelets that act as transcellular communicators. Inflammatory conditions exhibit elevated blood microparticle numbers compared to healthy conditions. Direct functional consequences of microparticle composition, especially internal composition, on recipient cells are poorly understood. Our objectiv...

background: platelet mps are produced automatically during platelet storage. their size is about 0.1 – 1 µm and have ability for sub- endothelium adhering, strengthen of platelet aggregation and also platelet pre- coagulation. in fact, the release of membrane particles helps to signal to the neighbor cells or to seclude target cells from apoptosis. the purpose of this study is to determine the ...
