Martijn van Raaij (promotion date: 10 December 2008) Biophysical characterization of α-synuclein aggregates: Parkinson’s disease at the nanoscale
The misfolding and aggregation of the protein alpha-synuclein is intimately linked to the pathology of Parkinson’s disease (PD). This thesis describes the use of advanced biophysical nanometrology instrumentation in an effort to understand the nanoscale morphology and secondary structure of aggregates of alpha-synuclein, called amyloid fibrils, both in vitro and in the brain tissue of Parkinson’s patients. ... read more |

Helmut Rathgen (promotion date: 3 December 2008) Microscopic properties of the super hydrophobic state
A super hydrophobic surface, is a hydrophobic surface with a micro scale texture. A drop of water floats on top of the texture like a fakir on a bed of nails, thereby forming microscopic liquid-gas interfaces that span between the ridges of the texture. ... read more |

Robert Moerland (promotion date: 6 November 2008) Controlling light emission with plasmonic nanostructures
This thesis discusses interactions of light and emitters with metallic (nano-)structures.
Investigations (theoretical and experimental) are carried out for a lens specifically for near fields, which allows imaging of the near field. The lens is composed of a thin metal film on a dielectric surface. A method is presented that can directly evaluate the performance of a metallic film as a lens, at optical frequencies. With a near-field optical probe, acting as a source, experimental data prove that the performance of a silver film as a lens improves with decreasing wavelength. ... read more |

In Yee Phang (promotion date: 24 October 2008) Marine bio-fouling surfaces: morphology and nanomechanics of barnacle cyprid larva adhesion proteins by AFM
In the barnacle’s cyprid larva stage, barnacles move to settle themselves on a hard marine underwater surface, f.e. a ship hull. The footprints they produce attract other barnacles and encourage them to colonize together. Using AFM-techniques the structure, mechanical properties and characteristics of the cyprid larva stage, are studied. ... read more |

Dawid Zalewski (promotion date: 24 October 2008) Electrokinetic methods for preparative electrophoresis on a chip
Capillary electrophoresis (CE) on a chip has one important drawback: the amount of an analyte obtained from a single run is very limited. Consequently, post-separation processing of the separated sample is challenging. To increase the amount of material available for a follow-up analysis, one can either pool fractions separated in subsequent runs or employ a method for continuous sample separation. ... read more |

Leon Woldering (promotion date: 5 September 2008) In this thesis several fabrication methods were investigated to obtain three-dimensional photonic crystals, in particular inverse woodpiles. Three-dimensional photonic crystals are predicted to be ultimate devices to completely control the propagation and emission of light. This is highly anticipated for applications in information communication and processing, but may also yield sensitive sensors useful for biology and even medicine. ... read more |

Vølodymyr Karpan (promotion date: 20 June 2008) Spintronics: a first-principles study
Despite the central role played by electron spin in many areas of condensed matter physics, it barely figured in the mainstream of charge-based microelectronics. The situation changed with the discovery of the giant magnetoresistance (GMR) effect, which is exploited now in the majority of magnetic reading heads of hard drive discs. ... read more |
