Mechanistic Optimization of Pressure Transmission for Defect Mitigation in Thick‐Walled Aerospace‐Grade Polyetherimide

SPE Polymers, Volume 7, Issue 3, July 2026.
Gate freeze time (GFT) controls internal void formation in thick‐walled injection‐molded polyetherimide (PEI). Extending GFT by optimizing cooling time and mold temperature reduces void size from the baseline (large voids) to an optimized condition (voids reduced), as confirmed by ultrasonic C‐scan inspection.

Chemogenetic Stimulation of the Dorsal Motor Nucleus of the Vagus Mitigates Autonomic Dysfunction and Memory Decline in Rat Model of Alzheimer‐Like Disease

Acta Physiologica, Volume 242, Issue 7, July 2026.
ABSTRACT Aim To test the hypothesis that Alzheimer‐like metabolic neurodegeneration rat model leads to an autonomic dysfunction, memory impairment, and hippocampal amyloid pathology and that long‐term chemogenetic stimulation of the dorsal motor nucleus of the vagus reverses these alterations. Methods Male and female transgenic Long Evans rats received

Comparing the In‐Plane Shear Behavior of Glass Fiber‐Reinforced and Carbon Fiber‐Reinforced Polymer Laminates With the Same Epoxy Matrix System in ±45° Tensile Tests

Polymer Composites, Volume 47, Issue 12, Page 11051-11068, 20 June 2026.
Schematic illustration of ±45° tensile testing, including detection of first‐ply failure (FPF) by optical crack detection and acoustic emission monitoring, comparison of FPF values with ASTM D3518 and D3039 criteria, and resulting ply level stress states at FPF for GF‐ and CF‐epoxy laminates.

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...
