Numerical study of interstitial fluid flow behavior in osteons under dynamic loading

BMC Musculoskeletal Disorders
Background The porous structure in bone tissue is essential for maintaining the physiological functions and overall health of intraosseous cells. The lacunar-canalicular net (LCN), a microscopic porous structure within osteons, facilitates the transport ...

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

Advanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.

Origins of Graphite Resistivity: Decoupling Stacking Fault and Rotational Misorientation

Advanced Science, EarlyView.
Interfacial dislocations critically influence interlayer transport in van der Waals (vdW) materials, yet quantifying their individual contributions remains challenging. We measure graphite's c‐axis resistivity and develop a decoupling strategy, revealing a resistivity ratio of ∼4507:74:1 for rotational misorientations, stacking faults, and AB stacking,

3D‐Printed Ion‐Conductive Hydrogels with Tunable Mechanical–Electrical Properties for Multimodal Sign Language Recognition

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 ...

Mechatronic greenhouse microclimate temperature control system

Mechanics and Advanced Technologies
Sudden changes in air temperature and humidity have a negative impact on crop cultivation. Modern methods of regulating the microclimate of greenhouse facilities are mostly reduced to regulating the flow and temperature of air masses. The purpose of this work is to analyze the thermal radiation of a greenhouse facility and to create a mechatronic ...
