Influence of the Tolerances of the Threaded Joints on Preloaded Bolted Connection

Journal of Mechanical Engineering
On the base of experimental results we can conclude that the mini bolt and large internal threads as well as large bolt and mini internal thread combination leads to developing of not satisfied preload. It means that the combination of marginal values of

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 ...

MELEGROS: Monolithic Elephant‐Inspired Gripper with Optical Sensors

Advanced Science, EarlyView.
MELEGROS is a monolithic, elephant‐inspired soft gripper integrating 3D‐printed optical sensors within a pneumatically actuated lattice. Simulation‐guided design decouples tactile and proprioceptive sensing. Characterized through grasping tests, MELEGROS can reach, scoop, and grasp, showcasing a paradigm where fully embedded sensing and continuous ...

Growth‐Like Swelling of 2D Precursors for Efficient Fabrication of Complex 3D Microstructures

Advanced Science, EarlyView.
The growth‐like swelling process fills photocured polymers into the elastomeric microstructures, inducing a significant swelling deformation of microstructures that can be maintained in the absence of solvents. The growth‐like swelling process breaks through the dependence of swelling deformation on the solvents, thereby expanding the application of 3D

Inhibiting cGAS‐STING to Preserve Mitochondrial–Nuclear Communication and Stemness in Young Tendon Stem Cells: A Hydrogel Strategy against Age‐Related Tendinopathy

Advanced Science, EarlyView.
A dual‐targeting strategy to rejuvenate aged tendons. A reactive oxygen species (ROS)‐responsive hydrogel co‐delivers a selenium nanozyme (scavenges ROS) and a STING inhibitor to tendon stem cells. This combined action restores mitochondria–nucleus communication, alleviates cellular senescence, and rejuvenates tendon regeneration, offering a novel ...
