Advanced Science, EarlyView.An ultrasoft yet tough organohydrogel (AQGL) with 5800% stretchability and 14.3 kPa modulus is developed via a novel molecular chain lubrication strategy. It features optical transparency, drying/freezing (−40°C) tolerance, antibacterial activity, conductivity, self‐healing, and adhesiveness.

A Biaxial Fatigue Specimen for Uniaxial Loading [PDF]
Strain, 2011 Abstract: The aim of this paper is to present a novel un‐notched fatigue test specimen in which a biaxial stress state is achieved using a uniaxial loading condition. This allows the problem of multi‐axial fatigue to be studied using relatively common one‐axis servo‐hydraulic testing machines.

Advanced Intelligent Systems, EarlyView.This work presents a robot‐assisted Doppler optical coherence tomography system for autonomous, wide‐field intraoperative assessment of microvascular anastomoses. Machine‐vision–guided probe positioning and adaptive scan planning enable three‐dimensional structural and hemodynamic imaging over extended vessel segments.

Equine Veterinary Journal, EarlyView.Abstract Background Condylar stress fracture of the third metacarpal bone (MC3) is a common catastrophic injury in Thoroughbred racehorses and is associated with parasagittal groove (PSG) subchondral osteolysis. Standing computed tomography (sCT) imaging enables sensitive identification of this fatigue‐induced early subchondral bone injury (SBI), but ...

Improved resonance method for fatigue test of full-scale wind turbine blades
AIP Advances, 2022 To further reduce the power of exciter in the common fatigue testing methods and increase the testing frequency to decrease the fatigue testing time, this paper proposes an improved fatigue testing method—Tug Fatigue Testing system (TFTs). The advantages
