16. Fluid Dynamics in Gas-Liquid Stirred Tank Reactors: Experimental and Theoretical Studies of Bubble Coalescence
Sammanfattning : This work deals with studies of bubble coalescence in turbulent flows of gas-liquid stirred tank reactors. Coalescence plays an important role in determining bubble size distribution, on which flow and mass transfer in such reactors largely depend. LÄS MER
17. Acoustic Manipulation of Particles and Fluids in Microfluidic Systems
Sammanfattning : The downscaling and integration of biomedical analyses onto a single chip offers several advantages in speed, cost, parallelism and de-centralization. Acoustic radiation forces are attractive to use in these applications since they are strong, long-range and gentle. LÄS MER
18. Acoustofluidic rare cell sample preparation
Sammanfattning : Acoustofluidics utilizes a combination of acoustics, in the form of ultrasound, and microfluidics to manipulate cells and particles. This has proven to be a versatile method that is gentle to the cells. In this thesis acoustofluidics has been used for processing rare cells in continuous flow. LÄS MER
19. Relaxation and Resonance in Brownian Motion-Coupled Resonators
Sammanfattning : 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. LÄS MER
20. Piezoactuators for Microfluidics : Towards Dynamic Arraying
Sammanfattning : Microfluidics can be used to increase performance, reduce reagent consumption and increase throughput in chemical analysis. With the forthcoming development of more advanced microfluidic systems, the integration of actuating elements becomes essential, giving the ability to control and manipulate fluid flow as well as sample or other components.
