In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque

Advanced Science, EarlyView.
In this paper, we present a wheel‐shaped direct‐current piezoelectric generator (DC‐PG) that fundamentally overcomes these constraints by producing phase‐stable DC electricity directly from rolling motion. By embedding this system into suitcase wheels, we demonstrated a fully integrated real‐time location tracking system powered solely by mechanical ...

Wearable Cooling Textiles of Thermal Conduction and Sweat Transfer for Personal Thermal Management

Advanced Science, EarlyView.
ABSTRACT Given rising global temperatures, advanced protective textiles hold significant potential to enhance productivity, conserve energy, and improve personal thermal comfort. Extensive research has shown that both thermal conduction and moisture management are equally critical in determining the comfort performance of textiles.

Electrochemical Nitrate Reduction Reaction to Ammonia at Industrial‐Level Current Densities

Advanced Science, EarlyView.
This review starts from the mechanism and theoretical basis of electrochemical nitrate reduction reaction (NO3−RR), and systematically summarizes and discusses the design strategies of industrial‐level current density catalysts. In addition, the progress of industrial‐level NO3−RR‐based electrolyzers, including flow reactor and membrane electrode ...
