1. Relaxation and Resonance in Brownian Motion-Coupled Resonators
Abstract : In physics, there exists a number of paradigm systems – exactly solvable models that can represent a wide variety of physical realizations. My research is concerned with two of these paradigm systems: the harmonic oscillator and Brownian motion. READ MORE

2. Brownian Relaxation Measurements of Magnetic Nanoparticles: Towards the Development of a Novel Biosensor System
Abstract : Magnetic measurements of the Brownian relaxation time of thermally blocked magnetic nanoparticles dispersed in a solution have been performed in order to determine the hydrodynamic size distribution of the particles. By measuring changes in the hydrodynamic size of the particles, the ammount of analytes attached to the surface of particles can be determined. READ MORE

3. Nanofluidics as a tool for parallelized single nanoparticle characterization: Fluorescence single nanoparticle catalysis and size determination through 1D Brownian motion
Abstract : Nanoparticles exist widely in nature and are objects of study in many scientific disciplines due to their high performance in a wide range of applications. With modern techniques that facilitate creating and shaping of nanoparticles into ever more complex shapes and compositions, characterization of particle properties is essential. READ MORE

4. Modelling transport of non-spherical particles in laminar flow
Abstract : A model has been developed that can be used to predict the transport of non-spherical particles in the nano- and micro scale range for different applications. This may be the flow in the lungs or flow taking place during composites manufacturing, but the model can be applied to many applications where the particle Stokes and Reynolds numbers are small.

5. Modelling Transport of Non-Spherical Particles in Small Channel Flow
Abstract : A model has been developed to predict the movement of oblate and prolate particles on amicro- and nano-scale in laminar channel flow, both for purposes of statistical aggregationand to study motion of single particles. For the purpose of this thesis the model has beenadapted to examine particle deposition patterns in the human lung and the filtration ofparticles during manufacturing of composites, but the possibilities of the model extendto all areas where the particle Stokes and Reynolds numbers are small.
