A Technique for Patellar Tendon Repair Using a Suture‐Free Nonwoven Polyethylene Terephthalate Implant

Arthroscopy Techniques, Volume 15, Issue 9, September 2026.
Abstract Surgical repair remains the standard of care for complete patellar tendon ruptures. However, healing is often challenging due to the tendon's poor biological environment and high tensile stress at the repair site. Bioinductive implants have been introduced to enhance tendon healing; however, they often lack early structural reinforcement. This

Bending Fatigue Evaluation and Failure Modes of Ultra‐Thin Silicon Chips on Flexible Substrates

FlexTech, Volume 2, Issue 2, Page 91-101, September 2026.
This study investigates the fatigue lifetime of 20‐μm‐thick chips under bending deformation. Three failure modes are identified: metal pad wearing, metal stress migration, and gold wire break. The underlying mechanisms are analyzed through micro‐scale characterization, and temperature effects on fatigue lifetime are explored.

Multilayer Architecture of PVD/HVOF Coatings Enables Transition in Wear Mechanism and Enhanced Tribological Performance

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT TiN films deposited by physical vapor deposition (PVD) are widely used as protective films due to their high hardness and wear resistance. However, their application under high‐load conditions is limited by poor load‐bearing capacity and susceptibility to spalling on soft substrates.
