Slow Release of Bioactive Alcohols From Butenolide Polymers and Coatings

Chemistry – A European Journal, EarlyView.
In this study we have reported the acid‐mediated release of bioactive alcohols from biobased alkoxy butenolide derived copolymers and coatings. It can potentially be applied for slow release of odors, pesticides, or drug‐related compounds from biobased polybutenolides.

Síntese e caracterização de copolímeros de propeno com 1-hexeno e 1,5-hexadieno Synthesis and characterization of propylene/1-hexene and propylene/1,5-hexadiene copolymers

Polímeros, 2012
Copolímeros de propeno com 1-hexeno e 1,5-hexadieno, contendo diferentes teores de comonômeros, foram obtidos utilizando técnicas de polimerização em lama e em massa com catalisadores Ziegler-Natta heterogêneos de alta atividade.

Harnessing Random Polymers as Chemoselective Catalysts With Structural Adaptability: Epoxidation of Olefinic Quaternary Ammonium Salts via Charge Recognition

Chemistry – A European Journal, EarlyView.
The development of chemoselective catalysts that operate across structurally diverse substrates remains a long‐standing challenge. Here, we demonstrate that a random heteropolymer bearing carboxylic acid and urea residues functions as a general epoxidation catalyst for olefinic quaternary ammonium salts.

Recent advances in photocatalytic hydrogen peroxide production

PhotoMat, EarlyView., 2023
We classify the representative photocatalytic materials for photosynthesis of hydrogen peroxide (H2O2) in recent years and discuss the related modification methods in detail, providing inspiration and insights for the future design of photocatalysts for H2O2 production.

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

The 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.

Unravelling the initiator‐only stage in alginate grafting: Radical‐induced depolymerization and its impact on acrylamide grafting efficiency

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Free‐radical grafting of natural polymers often assumes that initiators only create active sites before monomer addition. We tested this by exposing sodium alginate to potassium persulphate (KPS) under typical grafting conditions without monomer (acrylamide).
