Switching Between Continuum and Discrete States in a Continuum Robot With Dislocatable Joints
IEEE Access, 2021 Rigid linkages allow robots to lift heavy loads but prevent them from gently stretching and bending their bodies. Continuum robots without rigid linkages have a wide range of motion, safety, shape adaptability, and compliance.

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes
Advanced Materials, EarlyView.A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems
