Opposite Trends in Glass Transition and Vogel Temperatures in Long‐Chain Branched Poly(l‐Lactic Acid)

open access: yesJournal of Polymer Science, EarlyView.
The glass transition temperature (Tg), as determined by conventional DSC, increases from 326 K to 329 K while the Vogel temperature (Tv) decreases from 271 K to 255 K as the number of branch points per molecule increases from 0 to 3.3. ABSTRACT Poly(l‐lactic acid) (PLLA) is widely used as both a commodity thermoplastic and for engineering applications,

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

open access: yesVIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Photocatalytic Transfer Hydrogenation Using Plastic Hydrolysates as Hydrogen Donor

open access: yesAngewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Plastic waste is transformed into functional amines via solar‐driven transfer hydrogenation. Soluble monomers from acid hydrolysis of waste polymers serve as a hydrogen (electron/proton)donors in the selective reduction of nitroarenes using a visible light active photocatalyst consisting of cobalt promoted molybdenum disulfide integrated in cyanamide ...

Study of the Thermal and Hydrothermal Aging Effects on the Properties of 3D‐Printed Thermoplastic Polyurethane

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
Effect of post‐aging conditions on mechanical and thermal properties of FDM‐printed parts. ABSTRACT In this study, the thermal and hydrothermal aging of TPU produced with the FDM technique was simulated and subjected to a series of tests. The alterations in the internal structures of the samples that had been subjected to tensile, hardness, adhesive ...

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.
