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.

Direct extraction of functional whitened lignocellulose from wood via isocyanate modification in water–ethanol mixture

open access: yesPolymer International, EarlyView.
Direct extraction of lignocellulose from wood derivatives was achieved by introducing a bulky isocyanate substituent to lignin in a water–ethanol mixture. This process exploits the tunable solvent affinity of lignin to achieve its whitening, enabling the isolation of lignocellulose.

Enhancement of Chemical Stability of Sulfonated Polyvinylidene Fluoride Proton‐Conducting Membranes by Ceria Incorporation

open access: yesJournal of Polymer Science, EarlyView.
The chemical stability of SPVDF membranes was examined using Fenton's reagent test. It was found that the chemical stability of membranes was enhanced from around 80% to 96% by integration of ceria in the membranes. The ability of ceria to toggle between the two oxidation states was responsible for this enhancement.

Sodium Ions Affect GPR17 Conformational States and Functionality

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Sodium is an allosteric modulator of several class‐A GPCR regulating active versus inactive conformation state and may be a critical issue for the optimization of crystallization procedures. Herein, the role of Na+ in the regulation of GPR17 conformational states was studied through MD simulations of GPR17 wild‐type and mutated on two ...

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

open access: yesPest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.
