Sliding Wear Behavior of WP7V Tool Steel with Different Hardnesses Under Reciprocating Test Rig

Lubricants
This study involved the investigation of the mechanical and tribological behaviors of DIN 1.2344 and WP7V tool steels, quenched in a salt bath after austenitization at 1050 °C, followed by triple tempering for 2 h. The selection of tempering temperatures

Spatiotemporal Regulation of Hierarchical Assembly of Hydroxyapatite for Enamel Remineralization

Advanced Science, EarlyView.
Biomimetic repair exhibits unique advantages for enamel regeneration compared with conventional clinical treatments. An enzymatic mineralization system (EMS) is developed, where the resulting HAP nanorods hierarchically assemble into a highly ordered structure on the enamel surface through the spatiotemporal modulation of interfacial energies of ...

Tribological Analysis of Laser-Textured WC-Co Against Ti6Al4V Under Dry and Lubricated Conditions for Different Sliding Times

Lubricants
Machining titanium alloys, particularly Ti6Al4V, pose significant challenges in manufacturing engineering. The combination of high strength and low thermal conductivity makes Ti6Al4V a particularly difficult material to machine. One of these difficulties

Decoupling Stable Cyclic Deformation From Defect Accumulation in Metals

Advanced Science, EarlyView.
Introducing amorphous nanoparticles into a metal matrix enables a cyclic deformation regime where strain hardening and defect accumulation are decoupled. These nanoparticles act as dislocation sinks and undergo reversible shear transformations, sustaining microstructural stability over millions of cycles.

A Compact, High‐Performance, and Deformation‐Resilient Trielectrode Electrostatic Soft Pump for Soft Robotics

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Existing soft pumps often require tradeoffs between performance and compatibility with soft robotic systems. The proposed trielectrode electrostatic soft pump addresses these limitations through an innovative driving mechanism. Its design, which includes a trielectrode configuration and the use of compliant materials, improves operational efficiency ...

Intrinsically Linear and Robust Capacitive Strain Sensors Based on Area‐Variation Mechanism for Soft Machines

Advanced Intelligent Systems, EarlyView.
An intrinsically linear capacitive strain sensor based on an area‐variation mechanism is demonstrated. Lasermicromachined carbon fiber electrodes encapsulated in PDMS yield exceptional linearity and robustness. Integrated into smart gloves and soft continuum robot, this scalable strategy enables precise gesture recognition and real‐time shape ...
