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

Journal 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 ...

PFAS properties and destruction methods: A focus on enzymatic degradation

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 6, Page 1126-1152, June 2026.
Abstract Per‐ and polyfluoroalkyl substances (PFAS) are known as ‘forever’ chemicals and have lasting detrimental impact on the environment and living organisms. To understand PFAS molecules better, this review begins with an overview of PFAS definition, classifications and applications, and then provides a comprehensive summary and critical analysis ...

δ13C and δ15N Values of Residues Provide Insights Into Identification of the Explosive Source

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Postblast analyses of military and terrorist events will benefit from the capacity to learn more about the explosive materials used in an event. Here stable isotope ratio analyses (δ13C, δ15N) can provide additional information to complement identification of the explosive components.

Electrochemical Oxidation of Abietic and Dehydroabietic Acids for Sustainable Access to C‐7 and C‐15 Oxygenated Abietanes

ChemSusChem, Volume 19, Issue 9, 14 May 2026.
Batch and flow electrochemical methods enable direct C‐7 oxidation of abietic and dehydroabietic acids from colophony or their methyl derivatives to the corresponding ketones, while a mediated protocol enables additional C‐15 oxygenation, providing sustainable and selective routes to diversified abietane derivatives.
