Copper addition profoundly impacts MoNbTi multiprincipal element alloys. This study reveals copper's dual role, promoting microstructural refinement and strengthening intermetallics at optimal concentrations. An ideal copper content significantly boosts hardness and compressive strength, achieving superior mechanical performance.

Reliable Tissue Grasping in Robotic Minimally Invasive Surgery Enabled by Optical‐Based Slip Sensing
An optical‐based slip sensing method using a complementary metal–oxide–semiconductor image sensor with a built‐in infrared light emitting diode enables real‐time detection of tissue slippage—including displacement, direction, and speed—in robotic minimally invasive surgery.

Equal channel angular pressing of commercial pure copper under low strain amplitude (≈0.48) induces concurrent continuous and localized discontinuous dynamic recrystallization, forming a duplex structure influenced by strain heterogeneity and recovery. Moderate hardening after 4–12 passes results from progressive high‐angle grain boundary formation via

This article presents a comprehensive analysis of the intrinsic relationships and applicability of Hill48 yield criterion. The applicability and error evaluation conditions for Hill48 are established based on specific experimental data. A parameter calibration strategy for N‐value based on error minimization is proposed, and the predictive accuracy is ...

The dielectric elastomer‐based electropneumatic device (DE‐EPD) is a vacuum‐assisted ventricular assist device (VAD) that delivers high performance (85 mmHg, 6.8 L min−1) with low power consumption. Unlike traditional motor‐driven VADs, it is lightweight, quiet, energy‐efficient, and provides pulsatile flow. Validated in a simulated circulation system,
