A Quantitative Lithium Inventory Framework for Anode‐Free Lithium Metal Batteries
A component‐resolved lithium inventory framework quantitatively tracks Li redistribution across the cell in anode‐free NMC622||Cu pouch cells throughout cycling. Three sequential degradation stages are identified: formation‐driven cathode Li depletion, midlife inactive Li0 accumulation, and late‐stage runaway SEI thickening. The cathode, as the sole Li

A Multistage Venturi Amplifier for Rapid Inflation of Soft Robots
This work presents the amplifier inflator for soft robotic systems (AIRS), a compact, lightweight, and effective device for rapidly deploying inflatable structures to high pressure. By integrating a check valve with a Venturi‐based air entrainer, AIRS delivers an initial high‐flow output followed by pressurization, supporting fast inflation and ...

Abstract Children's learning increasingly extends into everyday informal settings, but what counts as learning in these contexts remains insufficiently understood. Focusing on family travel as a mobile and socioculturally situated informal learning context, this study adopts a sociocultural perspective and uses liquid learning as a sensitising concept ...
