A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions
Advanced Science, EarlyView.This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

Ultrasonic Pulse Velocity Versus Strength For Concrete In Qatar
, 1992 Compressive strength of concrete is widely accepted as a characteristic property indicating and representing its quality. The accuracy of both ultrasonic and mechanical strength is discussed and the advantages of ultrasonic testing are pointed out. Measurements of ultrasonic pulse velocity and mechanical crushing load of concrete cubes made from the ...

Thermally Induced Creep and Viscoelastic Behavior of Copper Micropillar Arrays
Advanced Science, EarlyView.Copper micropillar arrays are fabricated by electrodeposition within through‐glass‐via, and their thermally induced time‐dependent deformation is quantified. Nanoindentation creep, EBSD, and TEM reveal a heat‐treatment‐driven transition between grain‐boundary‐mediated deformation and dislocation‐dominated creep, while Kelvin modeling captures ...

Advanced Science, EarlyView.Two donor‐acceptor conjugated polymers, incorporating diketopyrrolopyrrole (DPP) and dialkoxybithiazole (2Tz) units with ethylene glycol (EG) side chains, exhibit relatively balanced ambipolar organic electrochemical transistor (OECT) performance. This ambipolarity enables the realization of single‐component complementary inverters capable of ternary ...

Advanced Science, EarlyView.A MXene‐enhanced electrochemical sensor enables the rapid and direct detection of methamphetamine. Molecular simulations reveal that specific MXene surface functional groups act as key signal amplifiers by facilitating interfacial interactions. The sensor demonstrates high sensitivity and robust performance in complex biological matrices.

Advanced Science, EarlyView.This study demonstrates that in high‐alloy systems, nanoclusters with high solute tolerance can effectively suppress compositional segregation. This mitigation leads to a concurrent 18.7% increase in strength and 41.5% improvement in ductility, which is attributed to a shear‐bypass synergistic strengthening mechanism. The findings provide a new pathway
