Graphene and amorphous carbon coatings for nitinol cardiovascular stents by direct chemical vapor deposition: A comparative insight

Materials & Design
Carbon-based coatings are promising for biomedical implants, including vascular stents, but fabrication on metals often requires adhesion interlayers or polymer-assisted transfer, increasing cost and complexity. Here, we report a simple, ambient-pressure

Long‐anchoring Stent Method as a Rescue Technique for Early Dysfunction of Covered Self‐Expandable Metal Stents in Distal Malignant Biliary Obstruction: A Retrospective Case Series

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objective Covered self‐expandable metal stents (SEMS) are widely used for treating distal malignant biliary obstruction (MBO). Severe SEMS angulation can cause stent dysfunction. Placement of a long double‐pigtail plastic stent inside the SEMS (the “long‐anchoring stent method”) may straighten the angulated SEMS, thereby achieving effective ...

Clinical Outcomes of Multi‐Hole Covered Self‐Expandable Metal Stents for Malignant Distal Biliary Obstruction: A Retrospective Comparative Study With an Exploratory Evaluation of 6‐mm Devices

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Covered self‐expandable metal stents (CSEMS) are widely used for malignant distal biliary obstruction (MDBO), but cholecystitis, post‐endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP), stent migration, and recurrent biliary obstruction (RBO) remain clinically important limitations.

Wear and Erosion-Corrosion Behaviour of Electroless Ni-P Composite Coatings with NiTi Nanoparticle Additions

, 2022
Electroless Ni-P coatings have high hardness and corrosion resistance but low toughness. The addition of super-elastic NiTi nanoparticles have been previously developed and shown to improve the coating’s ductility. However, the coating’s wear and erosion-

Autonomous self‐pollination provides reproductive assurance, whereas insect pollination enhances yield in sesame under tropical field conditions

Annals of Applied Biology, Volume 189, Issue 3, November 2026.
This study demonstrates that Sesamum indicum L. combines autonomous self‐pollination and insect‐mediated pollination under tropical field conditions. Autonomous self‐pollination provides reproductive assurance, whereas insect pollination increases grain yield by 28.6%, corresponding to a pollinator dependence of 22%.

Effect of Cu and CuP Additions on the Microstructure and Nanoindentation‐Based Fracture Behavior of CoNiAlSi Ferromagnetic Shape Memory Alloys

Advanced Engineering Materials, Volume 28, Issue 19, 7 October 2026.
Cu and combined Cu–P microalloying refine the microstructure and enhance the nanoindentation‐derived fracture resistance of CoNiAlSi ferromagnetic shape memory alloys without suppressing the martensitic transformation. Comparative SEM, DSC, and nanoindentation results reveal that the CuP‐containing alloy provides the most balanced response, achieving ...
