Novel Bioactive Multifunctional Polyphenols: A Chemo‐Enzymatic Approach

open access: yesChemistry – A European Journal, EarlyView.
One‐step synthesis of complex alkyl oxystilbenin glucosides (6‐47% yield) in alcoholic medium. Switching to ter‐BuOH as solvent afforded δ‐Viniferin diglucoside, with high selectivity and high yield (> 90%), that can be upgraded by enzymatic esterification to alkyl δ‐Viniferin diglucosides.

Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.

Rank‐based estimation of propensity score weights via subclassification

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Propensity score (PS) weighting estimators are widely used for causal effect estimation and enjoy desirable theoretical properties, such as consistency and potential efficiency under correct model specification. However, their performance can degrade in practice due to sensitivity to PS model misspecification.
