Sustainable chemistry and engineering

Overview
The team has succeeded and developed the research lines and good practices of the ERA Chair of Excellence (Green Chemistry) since 2019. - Organic chemistry application includes the development of cleaner organic synthesis methods to obtains small molecules and functional materials for biomedical or environmental applications. - A biodegradability facility has been installed and used by the team to identify low toxicity or mineralizable transformation products, targeting the “benign-by-design” approach. - Biomass valorisation has led to the development of chemical approaches for modifying lignin (with Dr Tiit Lukk under the umbrella of the Wood Chemistry group).- The risk management of technogenic accidents includes improvement of (i) antidotal and decontamination formulations for sustainability kits needed for the first responders and volunteers; (ii) disinfectant formulations and coatings to inactivate hospital-acquired infections or viruses on surfaces; composite of POM/PLA self-disinfecting films developed at TRL4 and recommended for further product development. - Medicinal chemistry research includes rational design of antidotes (reactivators of AChE inhibited by organophosphores compounds) and potential anticancer agents (PARP and VEGFR inhibitors). Innovative formulations for drug delivery involve functionalized nanodiamonds and sustainable micro/nanoemulsions.

Important results
In 2024: Research achievements were related to the development of green and sustainable platforms and formulations. A novel greener chloromethylation procedure for lignin under mild reaction conditions was elaborated and developed as a precursor for designing new functional materials, including (i) lignin-supported metal/metal oxide nanoparticles of designed metal composition, which may serve as a versatile and sustainable catalyst for a number of organic reactions (C-C coupling , “click”, hydrogenation) under continuous flow conditions; (ii) a series of quaternary ammonium and phosphonium lignin derivatives (QL), shown to be efficient antibacterial agents for coating and . efficient against clinical isolates of the ESKAPE strains, and (iii) novel long-chain esters of lignin, demonstrating excellent compatibility with thermoplastic polymer (PLA) to design a climate-resilient PLAlignin composites with advanced properties.
