Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols

Polymer International, EarlyView.
We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.

Microplastics in the menu of Mediterranean zooplankton: Insights from the feeding response of the calanoid copepod Centropages typicus

Marine Ecology, EarlyView., 2023
Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...

Synthesis and application of alginate@CuFe2O4 polymeric spheres in 17‐β‐estradiol adsorption processes in Amazonian rivers

Polymer International, EarlyView.
Magnetic alginate beads, functionalized with copper ferrite, effectively remove 17‐β‐estradiol from Amazonian water, exhibiting optimized 238.65 μg g−1 capacity, fast 40 min kinetics, easy recovery, and successful remediation. Abstract The presence of endocrine‐disrupting compounds, such as 17‐β‐estradiol, in aquatic ecosystems poses a significant ...

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

Polymer 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

Recycling‐Induced Changes of Molecular Weight and Structural Properties in PET Monopolymer Blends

Journal of Polymer Science, EarlyView.
The present study investigates the molecular weight, thermal, rheological, and mechanical properties of polymer blends of high and low molecular weight polyethylene terephthalate (PET) components. The research reveals that extrusion processing influences chain scission and chain extension, inhibiting the broadening of the molecular weight distribution ...

Survival of a potential bacterial biocontrol agent in the soil and its impact on microbial communities

Pest Management Science, EarlyView.
In soil microcosms, the candidate Bacillus persisted ≥6 months and caused modest community shifts whose transience and magnitude were soil dependent. Abstract BACKGROUND Sclerotinia sclerotiorum is a major crop pathogen commonly managed using fungicides.

Toward Sustainable Healthcare: Examining ESG‐Readiness in Austrian Regional State‐Owned Hospitals

Sustainable Development, EarlyView.
ABSTRACT Reporting on environmental, social, and governance (ESG) issues is now an essential part of responsible corporate governance, including in the healthcare sector. This study investigates the ESG reporting practices of Austrian regional state‐owned hospitals (rSOHs), contributing to the growing sustainability literature. Thirteen interviews with

Is the Plastic Waste Trade a Barrier to Sustainable Development? Empirical Evidence From RCEP Countries

Sustainable Development, EarlyView.
ABSTRACT There is widespread consensus on the threats that plastic waste poses to the environment. A significant obstacle to sustainable development, the trade in plastic waste may contribute to plastic pollution. The objective of this research is to look at how the import and export of plastic waste affect the sustainable development of Regional ...
