The evaporation of drops from super-heated nano-engineered surfaces
… the evaporating liquid is in contact with the surface, and film boiling, in which a layer of vapor separates the fluid from the surface. For a single evaporating drop, the Leidenfrost point occurs when the capillary and gravitational forces are surpassed by the upward pressure of the escaping …

Design and Optimization of Moldable Microstructures for Structural Color Generation
… of these simple moldable microstructures, microstructured silicon masters were fabricated with a variety of features to examine six design parameters: shape, size, spacing, depth, tone (holes or pillars), and multilayer effects. These were then photographed under constant lighting at …

Evaporation-induced non-wetting droplets on superhydrophilic surfaces
A droplet deposited on a rough, lyophilic surface satisfying the imbibition condition, results in spontaneous spreading and hence complete wetting. However, in this thesis, we demonstrate that this wetting behavior can be altered by superheating the substrate such that droplets can reside in a …

Magnetic fields near microstructured surfaces : application to atom chips
Microfabricated solid-state surfaces, also called atom chip', have become a well-established technique to trap and manipulate atoms. This has simplified applications in atom interferometry, quantum information processing, and studies of many-body systems. Magnetic trapping potentials with arbitrary …
