1. Cellulose nanofibril materials with controlled structure : the influence of colloidal interactions
Sammanfattning : Nanoparticles are very interesting components. Due to their very large specific surface area they possess properties in between molecules and macroscopic materials. In addition, a material built up of hierarchically assembled nanoparticles could obtain unique properties, not possessed by the nanoparticles themself. LÄS MER
2. Colloidal interactions and orientation of nanocellulose particles
Sammanfattning : Nanoparticles are very interesting building blocks. Their large surface-to-bulk ratio gives them different properties from those of larger particles. Controlling their assembly can greatly affect macroscopic material properties. LÄS MER
3. Colloidal interactions and arrested dynamics of cellulose nanofibrils
Sammanfattning : Over the past decades, concerns for the environment have increased and efforts to achieve a sustainable society have intensified. One particular challenge is to replace fossil-based plastics with biodegradable materials produced from renewable resources. LÄS MER
4. Acidaemia at Birth: Risk factors, diagnosis and prognosis, with special reference to maternal fever in labour
Sammanfattning : Acidaemia at birth is a result of an impaired intrauterine gas exchange. Between 1988 and 1996, acid-base balance in cord artery blood pH was assessed in 23 016 of 27 064 newborns (85%). Obstetric risk factors for acidaemia (cord artery pH < 7.05) were identified in a case-control study. LÄS MER
5. Aerosol Measurements as Applied for Exposure Characterization
Sammanfattning : It is important to decrease the burden of disease. This is in part achieved by decreasing risks. The aim of this thesis is to provide a methodology for the characterization of aerosol exposure, which may lead to negative health effects. LÄS MER
