1. Precipitation of Kraft Lignin from Aqueous Solutions
Abstract : One way of improving the materials yield of a kraft paper pulp process, and simultaneously providing the industry with aromatic macromolecular structures, is to extract lignin from the black liquor. This can be done by lowering the pH of the black liquor, which will result in the precipitation of the lignin. READ MORE

2. Preparation of Pharmaceutical Powders using Supercritical Fluid Technology : Pharmaceutical Applications and Physicochemical Characterisation of Powders
Abstract : The main aim of the thesis was to explore the potential of supercritical fluid (SF) techniques in the field of drug delivery. In particular, the relatively recently developed solution-enhanced dispersion by supercritical fluids (SEDS) technology has been employed in the preparation of particles/powders. READ MORE

4. Aerosol-Cloud-Precipitation Interactions - Studied using combinations of remote sensing and in-situ data
Abstract : Cloud droplets never form in the atmosphere without a seed in the form of an aerosol particle. Changes in number concentrations of aerosol particles in the atmosphere can therefore affect the number of droplets in a cloud. READ MORE

5. On the Local Filtration Properties of LignoBoost lignin: Studies of the influence of xylan and ionic strength
Abstract : Kraft pulping technology is currently the most commonly-used method for producing paper pulp from wood. A new and promising opportunity for Kraft pulp mills is to take a step towards becoming biorefineries by implementing technologies able to extract and convert the organic by-products, such as lignin, into a wide range of value-added products and chemicals.
