1. Diffusion-Induced Nonlinear Dynamics in Carbon Nanomechanical Resonators
Sammanfattning : The emergence of nanoelectromechanical systems has enabled the development of sensors capable of detecting mass, charge, force, position, and spin with an unprecedented precision. In particular, the low mass, high resonant frequency, and high quality factor of carbon nanomechanical resonators make them ideal for the creation of a high sensitivity mass sensor. LÄS MER
2. Development of a Novel QCM Technique for Protein Adsorption Studies
Sammanfattning : The first part of this thesis (Papers I and II) is concentrated on the development of a novel quartz crystal microbalance (QCM) technique to study protein adsorption. The second part (Papers III-V) is focused on the application of the technique on protein adsorption using well characterized surface-solution-protein systems. LÄS MER
3. Influence of Fluid Shear on Primary Nucleation of Organic Compounds in Solution Jin Liu Doctoral Thesis
Sammanfattning : In this work, three experimental systems have been used to study the influence of agitation/ fluid shear on primary nucleation. Three organic compounds have been used with different solvents, i.e. butyl paraben in ethanol solution, curcumin in ethanol solution and m-hydroxybenzoic acid in 1-propanol solution. LÄS MER
4. Studies of Glycosaminoglycan Interactions - Surface Immobilization Strategies and Biosensing Applications
Sammanfattning : Many important biological functions of glycosaminoglycans (GAGs) have been highlighted in research literature during recent years. GAGs often serve as function-bearing structural elements in the extracellular matrix (ECM), but are also constituents of the cell membrane. GAGs take part in various biological mechanisms, e.g. LÄS MER
5. Applications of the Complex Modulation Transfer Function on SEA-systems
Sammanfattning : The SEA coupling and dissipation loss factors are determined in-situ from Complex Modulation Transfer Functions, CMTF:s, based on measured impulse-responses. A quotient of CMTF:s is least-square curve-fitted to a SEA model and the SEA loss factors are determined from the results of the curve-fit. LÄS MER
