Plant‐derived nanovesicles as potential drug delivery systems for topical use: Emerging applications in dermatology and cosmetology

open access: yesVIEW, EarlyView.
Plant‐derived nanovesicles (PDNVs) are naturally secreted by fruit, vegetables, seeds, leaves and other natural sources. Used as drug delivery systems, they can combine intrinsic therapeutic activity, enhanced skin permeation and cargo‐carrying capacity, suitable for dermatological and cosmetic applications including hydration, antioxidant/anti ...

Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

open access: yesJournal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

Influence of Octaglycidyl‐POSS on Processing Behavior, Gelation Kinetics, and Thermomechanical Properties of a DGEBA/Polyamidoamine Epoxy System

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
The rigid, octafunctional Si8O12 cage of OG‐POSS incorporates into the DGEBA/polyamidoamine network as a multifunctional junction, raising the glass transition temperature (Tg) by up to 19°C and the apparent crosslink density non‐monotonically by 47%‐71% at 1.5, 3.0, and 5.0 phr loading.

Toward Silica‐Free Compliance: A Low‐Viscosity Sample Pretreatment Methodology for Crystalline Quartz Quantification in Viscous Pastes

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Crystalline quartz, the most common crystalline silica polymorph, is widely found in industrial products. It is of high regulatory relevance, because its fine fraction, a form of respirable crystalline silica, is classified as an occupational carcinogen, with product‐content thresholds (e.g., 0.1% (w/w) in the European Union) and stringent ...

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Extracellular fluid viscosity influences the mechanics and migration of MDA‐MB‐231 cells in a macromolecule‐dependent manner

open access: yesThe FEBS Journal, EarlyView.
Macromolecule‐dependent increases in extracellular fluid viscosity alter cell phenotype. These distinct macromolecules create different extracellular environments that modulate cell morphology and mechanoprotein expression, migration and invasion capacity, and cellular mechanical properties.
