1. Injectable calcium sulphate and calcium phosphate bone substitutes
Abstract : Two formulations of biphasic injectable bone substitutes have been developed for the treatment of bone defects and stabilisation of fragility fractures. The first formulation consists of a calcium sulphate matrix with embedded hydroxyapatite (HA) particles to provide osteoconductivity. READ MORE

2. Biomaterials as carriers for bone active molecules-An approach to create off-the-shelf bone substitutes
Abstract : Bone tissue is commonly transplanted during orthopedic surgeries, primarily for the management of bone defects caused by trauma or various orthopedic conditions including, but not limited to, infections and tumours. Bone grafts are a surgeon’s choice, but their associated drawbacks are paving the way for biomaterial based bone graft substitutes. READ MORE

3. Influence of solid solutions on the properties of some apatite-type calcium salts relevant to the production of phosphate and silicate cements
Abstract : The effects of non-stoichiometry and isomorphic substitutions on the properties of some apatite-type compounds were investigated. These investigations were performed both in the fields of Portland cement chemistry and apatitic calcium phosphate-based biocements. READ MORE

4. Biogas production from thin stillage : exploring the microbial response to sulphate and ammonia
Abstract : The biogas plant in Norrköping (Tekniska verken i Linköping AB, publ.), Sweden, operates with thin stillage, a residue from bio-ethanol fermentation, as the main feedstock. Thin stillage is energy-rich due to its high protein content, but due to its high nitrogen and sulphate content is a somewhat complicated feedstock. READ MORE

5. Properties of Interfacial Proteinaceous Films with Emphasis on Oral Systems
Abstract : The present thesis addresses three issues related to proteinaceous films at solid/liquid interfaces: adsorption, lubrication and enzymatic interactions. Most of the work has been devoted to oral systems. In addition, gelatin has been investigated as a model protein. READ MORE
