The Combined Effect of Gas Phase and Condensed Phase Mechanisms in Flame Retardancy of Polybutylene Succinate

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
A combination of DOPO and APP flame‐retardants results in a V‐0 UL 94 rating. ABSTRACT In this study, we addressed the challenge of eliminating, during combustion, the flaming dripping behavior of polybutylene succinate flame retarded with ammonium polyphosphate, a key barrier to achieving a V‐0 rating in the UL 94 flammability test without excessive ...

Thermal Degradation Kinetics and Flame‐Retardant Synergy in Zinc Borate/Red Phosphorus‐Filled Thermoplastic Polyurethane Composites

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
The synergistic interaction between red phosphorus (RP) and zinc borate (ZnB) enhances the thermal stability and flame retardancy of TPU by forming a dense, stable protective char layer. Non‐isothermal kinetic analysis confirms a complex degradation mechanism governed by conversion‐dependent activation energy.

Posidonia oceanica Leaves as a Natural Filler for Poly(Butylene Succinate‐Co‐Adipate) Composites: Characterization and Biodegradation Assessment in Seawater

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
This study shows that incorporating 5–10 wt.% Posidonia oceanica, with or without micro‐talc, in PBSA preserves thermal stability, modifying crystallization behavior, and maintains good filler dispersion and interfacial adhesion. Mechanical properties are moderately stiffened.

Time to Breakdown for Type I Motor Winding Insulation Under High‐Frequency High‐Slew‐Rate Square Wave Voltages

open access: yesHigh Voltage, EarlyView.
ABSTRACT The emergence of (ultra)wide bandgap ((U)WBG)‐based devices has significantly enhanced performance in high‐frequency switching applications, enabling breakthroughs in electric transportation, aerospace, and renewable energy systems. However, it also presents considerable challenges to insulation systems, such as electric motor winding ...

Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived bacterial semiochemicals

open access: yesInsect Science, EarlyView.
Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.

Availability of a Keystone Plant Resource Reduces Niche Overlap and Drives Distinct Species‐Specific Changes in Niche Breadth Among Small Rodents

open access: yesIntegrative Zoology, EarlyView.
We investigated how three rodent species respond to the seasonal availability of Araucaria angustifolia seeds. While Oligoryzomys spp. increased seed consumption and abundance during seed production, the more insectivorous Akodon paranaensis maintained a broader diet.

What is (de)politicization and what is wrong with it?

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract This article attempts to clarify the meaning of (de)politicization. Politicization sometimes refers to the inappropriate intrusion of partisan loyalties in nonpolitical social domains (affective politicization). Politicization can also constitute an ideal of civic agency and energy (contestatory politicization).

Rapid Human Skin Barrier Disruption by Sodium Dodecyl Sulfate and Associated Molecular Mechanisms

open access: yesAllergy, EarlyView.
Short‐term exposure to SDS rapidly disrupts human skin barrier integrity within minutes, as detected by real‐time electrical impedance spectroscopy. SDS‐induced barrier dysfunction is driven by oxidative stress, leading to suppression of immune/barrier mediators and activation of stress, lipid remodeling, and epidermal differentiation pathways ...

Depth and Procedure Specific Effects of Antimicrobial Versus Conventional Sutures on Surgical Site Infection: A Systematic Review and Meta‐Analysis

open access: yesANZ Journal of Surgery, EarlyView.
Antimicrobial sutures may be particularly beneficial in colorectal and abdominal procedures, where reductions in deep SSI may offset the additional suture cost. Several studies also reported favorable wound‐healing outcomes. ABSTRACT Background Surgical site infections (SSIs) are common postoperative complications that delay wound healing and increase ...
