Modeling real world phenomena using molecular dynamics and continuum simulations
… performed on the HOPG and crystalline quartz surface. The ice-like argon aggregate showed tendency to deform and fragment upon contact with the surface while the more rigid amorphous SiO 2 aggregate retained its structure and gained rotational energy upon contact with the smoother HOPG surface …

Computer simulation of radio-frequency methane/hydrogen plasmas and their interaction with GaAs Surfaces
… for the reactive ion etching of (100) GaAs surfaces. In addition a range of etching experiments was undertaken over a matrix of pressure, power and methane concentration. The resulting surfaces were investigated using X-ray photoelectron spectroscopy and the results were discussed in terms …

Advancements of Particle-Surface Interaction Studies through Novel Measurement Technique Development and Engineering Modelling
… speeds, pressures, and temperatures, ingested particles can inflict erosion upon the blades, stators, and other components within the operating turbomachinery. Left unchecked, this erosion can lead to an increase in surge and stall probability while also contributing to higher service frequency …

Nanoporous elements in microfluidics for multi-scale separation of bioparticles
The efficient isolation of specific bioparticles in lab-on-a-chip platforms is important for many applications in clinical diagnostics and biomedical research. The majority of microfluidic devices designed for specific particle isolation are constructed of solid materials such as silicon, glass, or …

In-situ steric stabilization of ultrafine titania particles synthesized by a sol-gel process
… concerns the synthesis of ultra-fine titania particles starting with titanium ethoxide as a precursor. The particle size and morphology was controlled using polymeric stabilizers which imparted in-situ steric stability during the particle growth. An attempt was made to elucidate the factors …

3D MEMS via (post-) buckling of micromachined structures and integration of bulk nanoporous elements in microfluidic devices
… of detecting and targeting extremely rare particles in blood. Nonetheless, intrinsic limitations in state-of-the-art MEMS processes and materials are hampering further diffusion of microtechnologies, and this thesis work extends MEMS capabilities in two areas: (a) a new technique for …

Interfacial properties of CH₄/C₂H₆ gas hydrate particles with chemical additives
… agglomeration by decreasing the hydrate interparticle cohesive forces, while still allowing hydrates to form. In contrast to THIs, the typical effective dosage of AAs is much lower (e.g., 0.5 - 2 vol.%). In this thesis, a novel method has been developed to evaluate and study AA performance to …
