Heat‐to‐Electricity Conversion Using Barium Strontium Titanate Multilayer Capacitors
Advanced Science, EarlyView.Lead‐free barium strontium titanate multilayer capacitors convert waste heat into electricity via the Olsen electro‐thermodynamic cycle. These capacitors achieve an energy density of 3.7 J cm−3, comparable to the performance of lead‐based ceramics. Their high dielectric strength and broad operating temperature window below 100°C make them practical for

Advanced Science, EarlyView.We develop bio‐based, star‐branched polyamides from itaconic acid and cadaverine with tunable lower critical solution temperature (LCST) transitions for dynamic solar modulation. Specific metal ion coordination with pyrrolidone moieties drives precise phase transitions via calcium‐induced salting‐in and sodium‐induced salting‐out mechanisms. Formulated

Photo‐Induced Stepwise Liquid Crystal Phase Transition Enabled by Hydrazone Photoswitch
Advanced Science, EarlyView.A judiciously designed bistable hydrazone photoswitch enables a photo‐induced stepwise “order‐disorder” phase transition in liquid crystals. The linear‐to‐bent isomerization disrupts molecular packing, allowing precise tuning of phase transition temperatures.
