Outcome of Calcium Silicate Sealer‐Based Obturation in Root Canal Retreatment: A CBCT‐Based Prospective Cohort Study

International Endodontic Journal, EarlyView.
ABSTRACT Background Calcium silicate sealers (CSS) have become the dominant approach to root canal obturation in many specialist practices, yet evidence on their performance in nonsurgical retreatment is sparse and CBCT‐based assessment remains uncommon.

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like

Dynamic Mechanical Loading Modulates Extracellular Vesicle Production and Cargo in Meniscus Fibrochondrocytes

Advanced Materials Interfaces, Volume 13, Issue 17, 8 September 2026.
Dynamic mechanical loading of outer meniscus fibrochondrocytes increases extracellular vesicle (EV) yield and alters EV composition. When applied to progenitor cells, these mechanically primed EVs modulate the expression of matrix‐related genes.

Seismic Performances of Replaceable Steel Connection with Low Yield Point Metal

Advances in Materials Science and Engineering, 2015
Compared with the traditional steel rigid connection, the beam-column connections with weakened beam end have better ductility, but the local buckling in the weakened zone and the overall lateral deformation may occur in strong earthquake.

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.

Coating Artificial Spider Silk Fiber with Magnetic FeCo: An Effective Strategy for Creating a Flexible Magneto‐Responsive Material

Advanced Functional Materials, Volume 36, Issue 48, 15 June 2026.
An original method is presented for producing artificial spider silk fibers with magnetic and magnetomechanical responsiveness, which consists in coating them with a nanometer‐thick layer of FeCo alloy by sputtering deposition. The challenge of combining organic materials and inorganic magnetic nanostructures is addressed, thus taking a step forward ...

Exploring the Tribological Properties of 3D Printed Polymer Composites: An Experimental Study

Polymer Composites, Volume 47, Issue 8, Page 6840-6858, 20 April 2026.
Tribological pin‐on‐disc testing of FDM‐manufactured pins. Pins made from PLA, TPU, bronze‐filled PLA (BRO), and their combinations were tested against a SAE 1020 steel disc to evaluate friction, wear, and surface morphology. ABSTRACT In recent years, additive manufacturing, especially 3D printing, has been gaining more space in the production of parts

Ti6Al4V‐Bioglass‐Copper Composites for Load‐Bearing Implants

Advanced Healthcare Materials, Volume 15, Issue 13, 3 April 2026.
We have designed and manufactured a novel Ti64‐based composite by adding 45S5 bioglass (BG) and copper (Cu). Adding BG on titanium improves wear resistance and biocompatibility, whereas Cu addition improves mechanical strength while providing inherent lifelong bacterial resistance.
