Dual Roles of Deep Eutectic Solvent in Polysulfide Redox and Catalysis for Intermediate‐Temperature Potassium‐Sulfur Batteries

Advanced Materials, EarlyView.
A dual‐functional NiS‐DES interfacial strategy enables highly reversible K2S2/K2S conversion in intermediate‐temperature K‐S batteries by balancing adsorption and activation of intermediates at the catalytic interface, achieving high capacity, long cycle life, and low‐cost energy storage. Abstract Potassium–sulfur (K‐S) batteries hold great promise for

Variable speed drive with hydraulic boost

International Journal of Fluid Power, 2019
This paper studies a variable speed drive with two hydraulic pump motors connected to an actuator. The torque load of the pump motors is reduced by connecting different pressures to the inlets of the pump motors. A method for real-time selection of the inlet pressures is developed.

Sacrificial Biofabrication for Vascularization: Concept, Materials, Technologies, and Applications

Advanced Materials, EarlyView.
Vasculature is indispensable for tissue viability in regenerative medicine. The sacrificial biofabrication enables precise fabrication of vascular channels by using temporary templates that are subsequently removed. This review defines the concept and delves into sacrificial materials, surrounding materials, fabrication technologies, and biomedical ...

Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

Advanced Materials, EarlyView.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic
