The Effect of the Aging Process of Polyamide 11 Used in Flexible Pipelines and Its Influence on the Permeability of Carbon Dioxide

Polymer Engineering &Science, EarlyView.
Field degradation inducing changes in the Polyamide 11 permeability. ABSTRACT This study investigates how long‐term natural aging affects the CO2 permeability of polyamide 11 (PA11) pressure sheaths recovered from decommissioned flexible risers. PA11 samples were extracted from two 18‐year‐old risers—a gas‐lift line and an oil‐production line—and ...

Preclinical Efficacy and Safety Evaluation of a Novel Controlled‐Expansion ePTFE‐Covered TIPS Stent in a Swine Model

Portal Hypertension &Cirrhosis, EarlyView.
This preclinical study evaluated a novel controlled‐expansion expanded polytetrafluoroethylene (ePTFE)‐covered transjugular intrahepatic portosystemic shunt (TIPS) stent in 11 swine, demonstrating 100% technical success, excellent deployability, and durable 6‐month angiographic patency without thrombosis, migration, fracture, or device‐related toxicity.

Application of Non‐Isothermal Network Theory With Curved‐Channel Element Characteristics to Predict Melt Conveying in High‐Performance Single‐Screw Extruders

Journal of Polymer Science, EarlyView.
This study presents a fast and accurate calculation tool to predict conveying of polymer melts in single‐screw extruders. Integrating generalized sub‐models into network theory allows to represent the complex screw shapes and material behavior more realistically. Tests on an industrial extruder show close agreement with experiments, outperforming older
