Analytical Approaches to Address Challenges in the Analysis of Cannabinoids in Vascular Matrices Using Mass Spectrometry

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Phytocannabinoids are bioactive metabolites derived from the Cannabis sativa plant. They have garnered attention due to their recreational uses and therapeutic potential. Although various analytical strategies have been employed for their analysis, mass spectrometry (MS) coupled to chromatographic separation is superior due to its sensitivity ...

Erosion Resistance Enhancement in Epoxy Composites by Recycled Rubber: Effect of Rubber Type

open access: yesPolymer Engineering &Science, EarlyView.
Erosion resistance enhancement in epoxy composites by recycled rubber. ABSTRACT Epoxy‐based materials have low erosion resistance due to their brittle nature, and toughness modification stands out for enhancing it. At this stage, the use of waste rubber as a reinforcement component in the composite system is of interest due to its role in providing ...

High‐strength composites by thiocracking of high‐polypropylene‐content mixed waste

open access: yesPolymer International, EarlyView.
Mixed plastic waste made up of polystyrene and polypropylene was reacted with elemental sulfur to give high‐strength composites. Abstract Mixed‐material municipal waste poses a persistent end‐of‐life management challenge because the heterogeneous composition limits efficient separation and recycling. After disposal, mixed‐material waste often fragments

Iron(III) ion reinforced P(NiPAAm‐co‐AA) beads as tunable smart organogels

open access: yesPolymer International, EarlyView.
Macroporous beads of PNiPAAm‐co‐AA copolymers were further crosslinked by iron(III) ions. The resulting beads are mechanically robust and reversibly responsive to a change of solvent from ethanol to ethyl acetate with half‐lives in the range of minutes.

Comparative Evaluation of Large Amplitude Oscillatory Shear (LAOS) Analysis Methods for Detecting Surfactant‐Induced Structural Evolution in Xanthan Gum Solutions

open access: yesJournal of Polymer Science, EarlyView.
A comparative large‐amplitude oscillatory shear analysis reveals how cationic surfactants progressively weaken xanthan gum networks. While conventional rheology identifies network softening, advanced LAOS methods uncover nonlinear deformation mechanisms and transient structural evolution that remain hidden in cycle‐averaged measurements.
