Thermal Degradation and Thermal Decomposition of Plasticized PVC Including POSS Additives for PVC Compounds: Mechanisms, Impact, and Performance of Standards

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...

Mathematical model of the zebrafish ventricular cardiomyocyte action potential and calcium transient

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study presents the development and validation of the first biophysically detailed computational model of the zebrafish ventricular action potential (AP). The model is based on a human cardiomyocyte framework and reparameterized using published and newly generated patch‐clamp recordings of zebrafish ionic currents.

Investigation on vented ethanol-gasoline vapor explosion characteristics initiated via single and dual sparks

open access: yesCase Studies in Thermal Engineering
Although vented explosions initiated via dual sparks have already been investigated to model accidental multi-explosions events, the vent coefficient (Kv) and vent location factors have not been analyzed together as far.

Atmospheric Deposition of Organic Pollutants: A Comprehensive Review of Sampling and Analytical Methodologies

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Atmospheric deposition of organic pollutants plays a crucial role in the transport and fate of contaminants in the environment, with implications for ecosystem health and human exposure. Persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs) and microplastics are increasingly recognized as transboundary threats due to ...

Analytical Green Star Area for Sample Preparation (AGSA‐Prep) as a Comprehensive and Practice‐Oriented Metric

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Sample preparation is a critical, yet often environmentally burdensome, step in analytical chemistry. While Green Sample Preparation principles aim to mitigate this impact, existing assessment tools such as AGREEprep offer room for improvement in the assessment process.

Clonal Cocoa Varieties Growth and Leaf Non‐Structural Carbohydrate Response to Field Stress Conditions

open access: yesPlant-Environment Interactions, Volume 7, Issue 3, June 2026.
ABSTRACT This study investigated the growth and leaf metabolism of clonal cocoa varieties in response to field stress conditions during wet and dry seasons. It was hypothesized that clonal cocoa varieties differ in their growth, photochemical efficiency, relative water content and central carbon metabolism under seasonal field stress conditions ...

Bayesian Decision Thresholds for Bushfire Warnings: Calibration and Robustness for Rare‐Event Risk

open access: yesAustralian &New Zealand Journal of Statistics, Volume 68, Issue 2, June 2026.
ABSTRACT Current bushfire warning systems communicate the probability of a warning given danger, but residents require the probability of danger given a warning. This misalignment, combined with the extreme rarity of catastrophic fires, often leads to the dangerous ‘wait and see’ behaviour.

A new model for deflagration fronts in reactive fluids

open access: yes, 1999
We present a new way of modeling deflagration fronts in reactive fluids, the main emphasis being on turbulent thermonuclear deflagration fronts in white dwarfs undergoing a Type Ia supernova explosion.

“Good job reporting this!”: Examining psychological needs and community building in YouTube conspiracy narratives

open access: yesPolitical Psychology, Volume 47, Issue 3, June 2026.
Abstract The proliferation of conspiracy theories online has tangible offline consequences, both on an individual and collective level. Conspiracy narratives have been associated with reduced belief in democracy, the rise of populist parties, and can act as a radicalization multiplier in such contexts.
