Advanced Science, EarlyView.This work successfully fabricated ion‐conductive hydrogels with low hysteresis and high conductivity using 3D printing technology. By adjusting the component ratios, the properties of the hydrogels can be tuned to meet diverse sensing requirements. Finally, a multimodal sensing sign language recognition system was constructed based on this hydrogel ...

Experimental investigations of the effects of cutting angle on chattering of a flexible manipulator [PDF]
, 1991 When a machine tool is mounted at the tip of a robotic manipulator, the manipulator becomes more flexible (the natural frequencies are lowered). Moreover, for a given flexible manipulator, its compliance will be different depending on feedback gains ...

Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2
Advanced Science, EarlyView.Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen

VIBRATION EFFECTS ON HAND-ARM-SYSTEM
INDUSTRIAL HEALTH, 1977 Electromyogram on the forearm flexor and extensor was observed with surface electrodes under conditions of experiments in which a subject was asked to grip a handle on a vibration table and was given vibration. In these experiments, factors concerning vibration exposure time, vibration amplitude, vibration frequency (30, 60, 125 and 250 Hz), gripping ...

Self‐Healing Starch‐Based Ionogels with Hydroneutral Dipole–Dipole Interactions
Advanced Science, EarlyView.This work introduces starch‐based, conductive, underwater‐healable, and transparent ionogels for soft electronics (SCUTEs). Starch macromolecules are partially substituted with cyanoethyl groups and incorporated with hydrophobic ionic liquid. The polar yet hydroneutral cyanoethyl groups facilitate strong dynamic dipole–dipole interactions that remain ...
