Our projects focus on the use of biopolymers such as cellulose, lignin, tannins and hemicellulose in formulations ranging from therapeutics, to home and personal care, agrochemicals and additive manufacturing, with the goal of reformulating without synthetic polymers. We are particularly interested in the use of green deep eutectic solvents to extract and modify cellulose, and […]

X-ray tomography is a powerful way of imaging the internal structures of materials, without having to apply advanced sectioning techniques. One limitation in X-ray tomography of soft matter (e.g. wood based materials, polymers) is the poor contrast between components, which is inherent due to low differences in electron density. This project aims to develop contrast

Cellulose nanofibrils (CNFs) are known to form associative structures even at very low concentrations; however, the fundamental mechanisms governing their assembly and the associated time scales remain poorly understood. Although significant research efforts are underway in this field, systematic, long-term investigations into the stability of CNF dispersions are still lacking. The aim of this project

This PhD project aims to identify and quantify the key factors that influence adhesive strength in bio-based adhesive systems. It focuses on understanding how adhesive chemistry, wood surface characteristics, and bonding conditions interact to affect both strength and durability. The research combines mechanical testing methods, such as tensile shear and compressive Strength, with material characterization

Despite substantial research efforts, the commercial alternatives for bio-based adhesives remain scarce. There are high requirements for adhesives used for lamination of paper in food packaging, e.g., stable adhesion over shelf life, food safety, water and temperature resistance to name a few. In particular, high-speed roll-to-roll processing requires an instant tack of the adhesive to
