Laryngeal Cryotherapy for Neurogenic Cough: Safety, Feasibility, and Prospective Outcomes

open access: yesThe Laryngoscope, EarlyView.
A prospective clinical trial investigated the safety and clinical outcomes of office‐based selective laryngeal cryotherapy for patients with refractory chronic cough. Patient were followed for 6 months posttreatment and had durable improvement in cough severity index and urge‐to‐cough scores and no serious long term adverse effects.

Polycarbonate Vitrimers and Dynamic Co‐Networks From Epoxide/Carbon Dioxide Copolymerization

open access: yesMacromolecular Rapid Communications, EarlyView.
This work demonstrates how CO2‐derived poly(propylene carbonate) and poly(cyclohexene carbonate) backbones influence vitrimer thermo‐mechanical behavior. By tuning backbone composition, epoxide crosslinker chemistry and blend ratios, the crosslinked materials span a wide property window, from highly extensible to stiff, glassy networks, establishing an

Design and Multibody Dynamics Modeling of a Novel High‐Static‐Low‐Dynamic‐Stiffness Vibration Isolation Mechanism Based on Euler Buckling Characteristics

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Vibration isolation has long been a critical area of research, with the design of isolators based on the mechanical properties of Euler buckling beams representing one of the primary approaches. Traditionally, the focus has been on utilizing the negative stiffness characteristics of a post‐buckled Euler beam in parallel with positive stiffness

Influence of Hybrid Co‐wrapped Yarn Structure on the Energy Absorption and Crack Propagation Resistance of Fiber‐Reinforced Composites

open access: yesPolymer Composites, EarlyView.
Helical wrapping of polyamide around E‐glass fibres deflects and bridges impact‐driven cracks, arresting damage that would otherwise propagate catastrophically in conventional side‐by‐side hybrid yarns. ABSTRACT Hybrid cowrapped (CW) yarns were engineered to enhance the impact resistance and damage tolerance of fiber‐reinforced composites.

Effect of Veil Interlayer Type and Placement on the Mechanical Response of Carbon and Glass Fiber/Epoxy Composites

open access: yesPolymer Composites, EarlyView.
Veil interlayers of five different chemistries (PI, FG, PPS, PEI, PEEK) were placed at two through‐thickness positions in carbon and glass fiber/epoxy laminates and evaluated under interlaminar shear (ILSS), three‐point bending (3PB) and axial buckling loading. The optimum placement was found to be loading mode dependent: near‐surface placement favored

Behavior of Injection‐Molded Nylon 6 Composites With Virgin and Field‐Exposed Waste‐Recycled Blends

open access: yesPolymer Composites, EarlyView.
Recycling field‐exposed Nylon 6 composites for sustainable secondary applications. ABSTRACT Every year, more than 18,600 metric tonnes of glass fiber‐reinforced Nylon 6 composite waste from sucker rod guides used in downhole oil and gas applications are landfilled due to uncertainty about retained performance after prolonged service exposure.

Comparative Analysis of Post‐Buckling Torsional Response in Carbon/Aramid Hybrid and Carbon Fiber Composites: Experimental Evaluation of Synergistic Effects Beyond Macro‐Scale Modeling Limits

open access: yesPolymer Composites, EarlyView.
Post‐buckling torsional response of carbon fiber (a) and intraply carbon/aramid hybrid (b) composites, revealing yarn‐level interaction beyond macro‐scale modeling limits. ABSTRACT This study investigates the buckling and post‐buckling performance of Carbon Fiber Reinforced Epoxy (CFRE) and intraply Carbon/Aramid Fabric Reinforced Epoxy (C/AFRE ...
