Enzymatic functionalization of hemicellulose to produce biobased cross-linkers

The overall aim of this project is to enzymatically modify glycans from hemicellulose to produce bio-based cross-linkers for applications in adhesives, hydrogels and other cross-linked materials. Many materials that we consider as bio-based such as wood fibreboards, hydrogels and stabilizers from non-fossil polymers are still dependent on cross-linkers that are of fossil origin and often […]

 Understanding bond strength of bio-adhesives

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

Imaging and analytical methods for interactions between bio-adhesives and porous substrates (wood, paper)

The goal of the experiment is to study interactions between bio-based adhesives (based on lignin-starch) and porous substrates (wood, paper).  X-ray Computed Tomography (nXCT) of specimens of thicknesses 50 μm with a bond line of 2 μm-thin will be used to study adhesive penetration at multiscale levels in relation to (surface and interfacial adhesion, porous

Bio-Adhesive Bonding -Evaluate Interfacial Properties of Bio adhesive Bonding

Bond strength is commonly used today as the primary measure of a glued product’s ultimate failure characteristics. While it is essential for ensuring product performance, bond strength alone is not sufficient to define most other properties. Once an adequate level of bond strength is achieved, characteristics such as bond stiffness, Fracture Toughness and other interfacial
