Review of Thermally Activated Twisted Coiled Polymer Actuators: A Materials Science Perspective
Thermally activated twisted and coiled polymer actuators (TCPAs) combine lightweight design, large deformation, and scalable fabrication for soft robotic and wearable applications. This review connects polymer structure, processing history, helix geometry, and thermomechanical characterization to actuator performance, highlighting current challenges in

Design, Development and Scaling Analysis of a Variable Stiffness Magnetic Torsion Spring
In this paper we report on the design, modeling, experimental testing and scaling analysis of a novel MAgnetic Variable stiffnEess spRIng-Clutch (MAVERIC) device, which may be used as the elastic element of Variable Stiffness Actuators (VSAs). The device,

Methyl N-(dimethoxyphosphoryl)carbamate
In the title compound, CH3OC(O)NHP(O)(OCH3)2, the P atom has a slightly distorted tetrahedral configuration. The mixed imide moiety can be described as cisoid–transoid in which the two opposing dipoles (P=O and C=O) are oriented with a O=C...P=O ...

N-(2,4-Dichlorophenyl)-4-methylbenzenesulfonamide
The molecule of the title compound, C13H11Cl2NO2S, is bent at the S atom with a C—SO2—NH—C torsion angle of −69.07 (16)°. The sulfonyl and aniline rings are rotated relative to each other by 53.0&

Wood Cellulosic Membrane With Abundant Nanochannels for Stabilizing Aqueous Zn‐Ion Batteries
A wood‐derived cellulosic membrane separator is developed to suppress dendrite growth in aqueous zinc‐ion batteries. Its aligned nanochannels and hydroxyl‐rich surfaces enable uniform Zn2+ flux, water immobilization, and interfacial stabilization. Zn||Zn cells achieve 1920 h of cycling, Zn||Cu cells maintain 99.5% Coulombic efficiency over 1000 cycles,
