Polyamide Acid–Based Surface Modification of Poly(p‐Phenylene Benzobisoxazole) Fibres Reinforcing Syntactic Foam for Using Them as High‐Performance Insulating Core Material

High Voltage, EarlyView.
ABSTRACT The insulating core is an important part of pillar composite insulators used in power transmission systems. Traditional insulating core materials suffer from various problems that can threaten the reliability of insulated equipment. Syntactic foam (SF) exhibits excellent properties, such as a low density, water penetration resistance and high ...

Passive environmental DNA sampling: A review of current practices, limitations and future directions for biodiversity monitoring

Methods in Ecology and Evolution, EarlyView.
Abstract Passive environmental DNA (eDNA) sampling is rapidly emerging as a powerful alternative to active sampling methods (e.g. direct water sampling), with a rapidly growing diversity of tested approaches but little methodological convergence.

Hydraulic In Vitro Characterization of MR‐Conditional Blood Pumps

Artificial Organs, EarlyView.
Cardiac surgery in neonates requires close placement of cardiopulmonary bypass machines due to limited blood volume, complicating MR compatibility. This study introduces three MR‐conditional blood pump prototypes. None interfered with MRI imaging, though RF‐related sensor effects remain untested.

Effect of Matrix Properties on Quasi‐Static and Fatigue Properties of Thermosetting Polyurethane and Its GFRP Composites

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT In this study, the influence of resin cross‐link density on thermomechanical properties and fatigue behavior of polyurethane resins and glass fiber‐reinforced polyurethane (PUR‐GFRP) composites was investigated. This material is a candidate for renewable energy applications like rotor blades in wind turbines.

Comparative Analysis of Three Vertebral Screw Placement Directions in Anterior Thoracolumbar Fracture Surgery: A Finite Element Study

Orthopaedic Surgery, Volume 17, Issue 5, Page 1464-1477, May 2025.
This study compares the biomechanical effects of three anterior fixation systems in thoracolumbar surgery—HXTL, NHXTL, and Medtronic's CD Horizon ANTERIOR. Finite element analysis evaluates stress and displacement across vertebral bodies and support structures under varying load conditions. Results indicate the HXTL system minimizes nail–rod stress yet
