Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols

open access: yesPolymer 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.

Roll‐to‐Roll Processing of Biodegradable Multilayer Barrier Packaging Structures

open access: yesPackaging Technology and Science, EarlyView.
This work demonstrates that novel packaging materials built using biobased and biodegradable materials can be produced in pilot‐scale and converted into functional barrier packaging. The proposed structures are anticipated to make a strong impact in use‐cases where the risk of environmental littering is elevated, such as snacks and take away meals ...

Gas check prevention during calendering of poly(vinyl chloride) films using poly(caprolactone)‐based additives

open access: yesJournal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 441-452, March 2025.
Three poly(caprolactone) (PCL)‐based additives of differing molecular weights were used as a secondary plasticizer to prevent gas checks in PVC films produced through calendering. Results showed that chemical and physicochemical properties influence the prevention or reduction of gas checks, unlike rheological properties including complex viscosity and

Crystal structure and biochemical analysis of the polyester‐degrading carboxylesterase SM0281 from the symbiotic legume‐associated rhizobacterium Sinorhizobium (Ensifer) meliloti

open access: yesThe FEBS Journal, EarlyView.
The microbial degradation of synthetic polyesters such as polyethylene terephthalate (PET) is mediated by diverse α/β‐hydrolases, many of which remain poorly characterized. In this study, we investigated the α/β‐hydrolase SM0281 from Sinorhizobium meliloti and found that it exhibits robust carboxylesterase and polyesterase activities toward PET, PCL ...

Green Sorptive Sampling Coupled With UHPLC–IMS–MS and GC×GC–TOFMS for Characterization of Migrating Substances From Plastic Food Contact Materials [PDF]

open access: yesJ Sep Sci
A green PDMS sorptive sampling loop coupled with complementary liquid and gas chromatography–mass spectrometry enabled detection of migrating chemicals from plastic food contact materials under everyday‐use scenarios. The approach revealed diverse additives and non‐intentionally added substances, supporting improved exposure assessment of plastic ...

A Preliminary Field Study to Evaluate the Efficacy of Spiramycin and Paromomycin Against Cattle Cryptosporidiosis

open access: yesZoonoses and Public Health, EarlyView.
ABSTRACT Introduction Cryptosporidium is responsible not only for large economic losses in the livestock sector, but also for high mortality in infants and immunocompromised people all over the world. Although multiple treatments have been tested in both animals and humans, no drug has yet been found to be 100% effective.

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.
