Fully Printed Electrocaloric Heat Pump
Advanced Materials Technologies, EarlyView.A system based on a flexible printed PEDOT:PSS/P(VDF‐TrFE‐CFE) electrocaloric membrane. The membrane periodically alternates between the cold and hot sides following its electrocaloric cycle and successfully generates a temperature difference. The entire fabrication process is industrially scalable, cost‐effective, and based on widely accessible ...

Advanced Optical Materials, EarlyView.The particle with high surface hydrophilicity exhibits strong thermophoretic attraction, as its dense hydration layer enhances the role of interfacial water molecules in determining thermophoretic mobility over other ionic effects. This finding elucidates the mechanism underlying the robust thermophoretic accumulation of Escherichia coli in high ...

Advanced Optical Materials, EarlyView.Metasurface shows selective solar–thermal energy conversion with high‐activity solar/laser‐driven chemistry. The breakthrough is co‐designing broadband FP‐cavity + plasmonic LSPR/SLR resonances in an ultra‐thin metamaterial so that it not only harvests the most efficient proportion of solar radiation but also suppresses mid and IR emissivity. Moreover,

On–Off Switchable Micromotors for Use in Steerable Microvehicles
Advanced Robotics Research, EarlyView.Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,
