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 ...

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.

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

open access: yesThe FEBS Journal, EarlyView.
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

Parenteral iron—Does it increase infection risk?

open access: yesVox Sanguinis, EarlyView.
Abstract Background and Objectives Iron deficiency (ID) and iron deficiency anaemia (IDA) are prevalent conditions impacting various patient populations, both surgical and non‐surgical conditions. The advent of patient blood management (PBM) has promoted intravenous (IV) iron therapy as an alternative to oral iron and blood transfusions.

From Agri‐Waste to Heavy‐Duty Packaging: Upcycling Tomato Processing By‐Products Into Sustainable Bio‐Composite Polymeric Films

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 23, June 15, 2026.
From tomato sauce waste to sustainable packaging: tomato processing by‐products are upcycled as fillers in biodegradable polymers and processed through blown film extrusion to fabricate heavy‐duty bags, enabling a circular and value‐added use of agri‐food residues.

Directed Evolution of an Efficient Polycarbonate Depolymerase With Exceptional Operational Stability

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Here, we show that well studied PET hydrolases can be re‐engineered via directed evolution to deconstruct alternative aromatic‐containing commodity polymers. Introduction of only three mutations into LCCICCG was sufficient to generate an efficient polycarbonate hydrolase with high operational stability that can fully depolymerize a polycarbonate sample

Cytosolic Phosphoenoylpyruvate Carboxykinase Deficiency: Clinical, Biochemical, and Genetic Features of Five Non‐Finnish Patients

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 6, Page 1192-1203, June 2026.
ABSTRACT Cytosolic phosphoenoylpyruvate carboxykinase (PEPCK‐C) is an essential, rate‐limiting enzyme in the gluconeogenesis pathway. PEPCK‐C deficiency presents with hypoglycaemia, hyperlactataemia and hepatopathy, and was first reported in association with bi‐allelic PCK1 variants in 2014.
