2. 1. Separation of Proteins with Capillary Electrophoresis in Coated Capillaries with and without Electroosmosis : Studies on Zone Broadening and Analytical Performances

   Author : Sheila Mohabbati; Douglas Westerlund; Bo Karlberg; Uppsala universitet; []
   Keywords : Pharmaceutical chemistry; Capillary electrophoresis; capillary coatings; proteins; zone broadening; zone sharpening; efficiency; resolution; protein-surface adsorption; protein-buffer interaction; analytical performance; Farmaceutisk kemi;

   Abstract : Proteins have such structural features that they may interact with different types of surfaces by all possible forces, i.e., electrostatic, hydrogen bonding, hydrophobic. In this thesis two different types of coatings for fused silica capillaries aimed to eliminate such interactions have been studied. READ MORE

4. 2. Adsorption behaviour of bottle-brush and block copolymers at solid-liquid interfaces

   Author : Geoffrey Olanya; Per M. Claesson; Orlando Rojas; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Adsorption; Lubrication; Layer viscoelasticity; Protein repellency; Polymer architecture; Silica; Bottle-brush polymers; Poly ethylene oxide ; PEO; Block copolymer; Poly N-isopropylacrylamide ; QCM-D; AFM; Reflectometry; Surface and colloid chemistry; Yt- och kolloidkemi;

   Abstract : This thesis was spurred on by needs of current scientific and technological developments in the area of surface modification by use of adsorbed polymer layers. The importance of surface properties of polymer layers can be imparted in a broad spectrum of interfacial-related applications like lubrication, colloidal stability, detergency, and protein resistant surfaces, to just mention a few.

5. 3. Anisotropic Protein Interactions in Salt Solutions and at Interfaces: Coarse Grained Modeling

   Author : Anil Kurut Sabanoglu; Beräkningskemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anisotropic interactions; protein electrostatics; phase association; surface adsorption; coarse grained models; Monte Carlo simulations;

   Abstract : Anisotropic protein interactions have a strong orientation dependence resulting from an uneven distribution of charged and hydrophobic residues on the protein surface. They play an important role in protein behaviors such as protein association, surface adsorption and phase separation. READ MORE

6. 4. Protein-Polymer Interaction and Association in Aqueous Solution

   Author : Malin Jönsson; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; Makromolekylär kemi; Macromolecular chemistry; enzymologi; Proteiner; enzymology; Proteins; Aqueous two-phase systems; Monte Carlo Simulations; hydrophobic effect; surface hydrophobicity; plasmid DNA; Protein; polymer;

   Abstract : The aim of this thesis has been to study protein-polymer interaction and association. Two different techniques were used; Monte Carlo simulations were combined with partitioning in polymeric aqueous two-phase systems. Monte Carlo simulations have been used to evaluate the hydrophobic interaction in electrolyte solution. READ MORE

7. 5. Properties and fungal decomposition of iron oxide-associated organic matter

   Author : Zhaomo Tian; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Soil organic matter (SOM) stores the largest quantity of C in terrestrial ecosystems. Most SOM can be decomposed by microorganisms and released as CO2 into the atmosphere. The remaining fraction of SOM can be resistant against microbial decomposition over centuries to millennia. READ MORE
