Comparing fixation pressure and operator proficiency in the use of pelvic binders: a study of the SAM Pelvic Sling II and AP MAX Truncal Orthosis

Scientific Reports
Pelvic fractures are associated with high morbidity and mortality and often require immediate stabilisation. Pelvic binders help control haemorrhage; however, variations in design and operator proficiency may affect performance.

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Flexural Behavior of 3D‐Printed Porous Bouligand‐Structured Polymers: Influence of Pitch Angle and Porosity

Advanced Engineering Materials, EarlyView.
This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight

A novel clip-based nerve compression model with high stability and reproducibility for the study of chronic nerve injury associated with neuropathic pain

Frontiers in Neuroscience
BackgroundThe pathogenesis of neuropathic pain (NP) is complex and remains incompletely understood, making it essential to establish animal models that can stably and reproducibly recapitulate pain behaviors and functional impairments.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.
