Soil Contamination Around the Copper Smelter and the Use of Soil Microarthropods as Bioindicators

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil contamination from smelter emissions, including heavy metals (HM), rare earth elements (REEs), and sulfur, poses a significant threat to soil ecosystems. In the immediate vicinity of the Głogów Copper Smelter, HM concentrations were several times higher than in more distant forest stands.

Spatiospectral Photoacoustic Microscopy With Gain‐Switched Ti:Sapphire Laser for High‐Accuracy Molecular Dynamics Imaging

open access: yesLaser &Photonics Reviews, EarlyView.
Spatiospectral photoacoustic microscopy is enabled by stable, wavelength‐tunable dual‐pulse excitation from a gain‐switched Ti:sapphire laser. Intrinsically synchronized 532‐nm and NIR‐I pulses provide single‐scan, co‐registered mapping of oxygen saturation and indocyanine green dynamics in vivo.

Correlating Pulmonary Hemodynamics With HP 129Xe Dissolved‐Phase MRSI in a Controlled Porcine Intervention Study

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Pulmonary hypertension is related to a 1‐year mortality ranging from < 5% to > 20% in low‐ and high‐risk groups. Right heart catheterization is the diagnostic gold standard, associated with a 1.1% rate of severe adverse events, posing the need for a non‐invasive diagnostic tool.

Remote sensing and citizen science for habitat mapping: A machine learning approach to lowland heathland in Surrey, UK

open access: yesPeople and Nature, EarlyView.
Abstract In a time of extensive global biodiversity loss, conservation efforts increasingly rely on high‐resolution, accurate, up‐to‐date habitat maps to guide decision‐making and strategic interventions. Many products have been developed in response, using machine learning (ML) methods to automate habitat classification, often relying on satellite ...

Effect of Nanosilica Aggregates/Agglomerates on Functional Properties of Poly(Butylene 2,5‐Furandicarboxylate)‐Based Nanocomposites

open access: yesPolymer Composites, EarlyView.
Effect of nanosilica aggregates/agglomerates on oxygen and water vapor diffusivity of PBF/SiO2 nanocomposites. ABSTRACT The nanofillers inclusions in poly(butylene 2,5‐furandicarboxylate) (PBF)/SiO2 nanocomposites were found to consist of aggregates and agglomerates of nanosilica particles.

Tailored for Binding: Alanine‐Modified Poly(1‐Naphthylamine) Targets Serum Albumins

open access: yesPolymer Engineering &Science, EarlyView.
Alanine modified poly(1‐naphthylamine). ABSTRACT This study presents a new approach for modifying the structural and functional properties of poly(1‐naphthylamine) (PNA) by incorporating the amino acid alanine (Ala) in different molar proportions (80/20, 50/50, and 20/80 for PNA/Ala) through an ultrasound‐assisted polymerization process.

Computational design of poly(p‐phenylene vinylene)‐based gas sensors: tunable reactivity and selectivity via side‐group functionalization

open access: yesPolymer International, EarlyView.
Side‐group functionalization enhances the reactivity and optoelectronic properties of poly(p‐phenylene vinylene) (PPV) derivatives for chemical sensing. PPV‐CN and PPV‐NO2 display strong interactions and pronounced responses, providing molecular‐level insights for designing high‐performance polymer‐based sensors.

Acid Sulfite Pulping of Hemp: Effects of Processing Conditions on Lyocell Pulp Quality

open access: yesJournal of Polymer Science, EarlyView.
Industrial hemp is emerging as a promising renewable source for next‐generation textile fibers. This study evaluates whether acid sulfite pulping can produce hemp‐based dissolving pulp suitable for lyocell manufacturing. While the process is historically linked to increased cellulose accessibility, it did not achieve the low lignin content and ...

Building Sulfone Bridges: Multi‐Technique Analysis of Thermally Induced Cross‐Linking in Highly Sulfonated Poly(Phenylsulfone)

open access: yesJournal of Polymer Science, EarlyView.
Highly sulfonated poly(phenylsulfone) undergoes controlled thermal cross‐linking through sulfone bridge formation, exploiting the dual role of sulfonic acid groups as both proton‐conducting functionalities and reactive precursors. The resulting fluorine‐free membranes exhibit enhanced hydrolytic, thermal, and mechanical stability while maintaining ...
