Single Versus Double Screw Extrusion: Impact on Mechanical Performance and Crack Resistance for a Virgin, Recycled, and Blended Polypropylene

Polymer Engineering &Science, EarlyView.
Schematic overview of the study approach and key findings. ABSTRACT To evaluate the influence of extrusion on material performance, three processing methods, single extrusion (1x Ex), double extrusion (2x Ex), and double screw compounding (C), were investigated for virgin polypropylene (vPP), recycled PP (rPP), and a blend containing 10% rPP (rPP10 ...

Diagnosis of Portal Hypertension: Advancing Towards Non‐Invasive Solutions

Portal Hypertension &Cirrhosis, EarlyView.
This review systematically summarizes a full spectrum of non‐invasive diagnostic approaches for portal hypertension (PH), including imaging modalities, elastography, serum biomarkers, composite scoring systems and endoscopic ultrasound‐guided portal pressure gradient (EUS‐PPG), and analyzes their performance across different liver disease etiologies ...

Hierarchical Reaction‐Induced Phase Separation in Epoxy/Oligomeric Poly(phenylene ether) Blends: Multiscale Structural and Mechanical Heterogeneity

Journal of Polymer Science, EarlyView.
Hierarchical morphology does not always improve toughness. In epoxy/oPPE blends, curing creates oPPE‐rich primary domains containing nanoscale secondary heterogeneity, as revealed by microscopy, X‐ray scattering, and AFM nanomechanics. Fracture observations show that primary domain–matrix interfacial separation limits tensile ductility despite the ...

Automatic insect identification, counting, and monitoring techniques: a review

Pest Management Science, EarlyView.
Automated insect monitoring increasingly integrates optical, acoustic, infrared, radar, electrostatic, and biosensing technologies with artificial intelligence. No single approach is universally optimal; reliable deployment depends on task‐specific validation, representative datasets, robustness under field conditions, energy autonomy, connectivity ...

Gentiopicroside Regulates EGFR and Induces Its Lysosomal Degradation to Attenuate Heart Failure

Phytotherapy Research, EarlyView.
GPS attenuates pressure overload‐induced cardiac remodeling by promoting lysosomal degradation of EGFR. TAC‐induced EGFR accumulation activates AKT/ERK1/2 signaling and drives pathological cardiac hypertrophy, fibrosis, apoptosis, oxidative stress, and cardiac dysfunction. GPS promotes lysosome‐dependent EGFR degradation, thereby limiting excessive AKT/
