 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

Green chemistries for biobased polymers

This project is part of the BioGlue Centre (https://www.slu.se/en/departments/forest-biomaterials-technology/bioglue-centre/), which is a co-operation between three universities and many industries aiming to have a better understanding around adhesives and bonding for wood materials in different sectors, such as furniture, construction, and packaging. In this project specifically, the aim is to map suitable and available bio-based raw

Methodologies providing new insights into the fundamentals of the pulping process

Today’s knowledge of what happens concerning the kinetics and other phenomena in the digester during the pulping process is mainly the result of the use of inductive methods. Based on these methods, generalised models have been formulated that are applied for process development as well as for industrial process optimisation.  Recent studies (e.g., Mattsson et

Improved uniformity of the fibers liberated in the kraft pulp digester 

This project sets out to elucidate mass transport characteristics during delignification of wood chips as a means of understanding and controlling non-uniform delignification effects, associated to low efficiency and poor property control in the current pulping processes. To obtain information on local variations of delignification effect in a wood chip, the treated chips will be
