1. Studies on cell wall recycling and modification in Gram-negative bacteria
Sammanfattning : The bacterial cell wall is made from peptidoglycan (PG), a heteropolymer which forms a bag-like exoskeleton that envelopes the cell. PG is constantly remodelled during growth and division, and in response to environmental stimuli. LÄS MER
2. Immobilizing catalysts on textiles : case of zerovalent iron and glucose oxidase enzyme
Sammanfattning : Catalytic systems are one of the most effective technologies of modern chemical processes. The system uses a molecule called ‘catalyst’ that is capable of catalyzing a reaction without being produced or consumed during the process. LÄS MER
3. Evaluation of Non-Metallic Inclusions after Deformation and Their Effect on the Machinability of Steel
Sammanfattning : The presence of non-metallic inclusions (NMIs) have critical effects on both the mechanical properties and machinability of steels. In the present thesis, one focus is to study the characteristics of deformed sulfides (MnS) for a stainless steel (3R65) and a tool steel (42CrMo4). LÄS MER
4. Surface characterisation of thermally modified spruce wood and influence of water vapour sorption
Sammanfattning : Today there is growing interest within the construction sector to increase the proportion of biobased building materials made from renewable resources. By-products or residuals from wood processing could in this case be valuable resources for manufacturing new types of biocomposites. LÄS MER
5. Engineering enzymes towards biotherapeutic applications using ancestral sequence reconstruction
Sammanfattning : Enzymes are versatile biocatalysts that fulfill essential functions in all forms of life and, therefore, play an important role in health and disease. One specific application of enzymes in life science is their use as biopharmaceuticals, which typically benefits from high catalytic activity and stability. LÄS MER
