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.

Upgrade des CMS‐Detektors für die Hochratenphase des LHC: Die Runderneuerung von CMS

open access: yesPhysik in unserer Zeit, EarlyView.
Ab 2030 wird der LHC in der Hochratenphase laufen. Die erheblich gesteigerte Proton‐Proton‐Kollisionsrate erfordert ein grundlegendes Update der beiden großen Detektoren ATLAS und CMS, dessen Runderneuerung hier vorgestellt wird. Zusammenfassung Ab 2030 soll der Large Hadron Collider (LHC) am CERN in der Hochratenphase (High Luminosity, High‐Lumi ...

Dose–response modelling uncovers compound‐specific inhibitory effects of host defence volatiles on mountain pine beetle fungal symbionts

open access: yesPest Management Science, EarlyView.
Host defence volatiles inhibit mountain pine beetle fungal symbionts in a compound‐ and enantiomer‐specific manner, with distinct dose–response profiles that reveal the multitarget chemical defences of beetle–fungi symbiotes. Abstract BACKGROUND The mountain pine beetle relies on symbiotic fungi to overcome host tree defences, yet these fungi must ...
