Spring 2013
Removal of a drop from its substrate may be gradually (e.g. evaporation) or all at once (e.g. shedding). In this thesis, drop adhesion force as a base for understanding the all at once removal of a drop from its substrate, and drop evaporation in room temperature as one of the gradual removal...

Development of a Novel Electro-thermal Anti-icing System for Fiber-reinforced Polymer Composite Airfoils
DownloadFall 2012
Given the trend towards expanded use of polymeric composites for wind turbine blades and aircrafts wing, icing of polymer composite airfoils is a challenge; this thesis is addressing this issue from a conceptual perspective. For the first time, the concept of embedded thermal elements as an...

Magnetically targeted deposition and retention of particles in the airways for drug delivery
DownloadSpring 2010
This thesis examines the mechanisms of magnetic particle deposition and retention in human airways for magnetically targeted drug delivery. As this is a novel application, fundamental studies were performed to establish the necessary background knowledge for further development. Magnetic particle...

Spring 2013
This thesis is concerned with the effect of mechanical wear on superhydrophobic surfaces (SHS). This work, for the first time, systematically details the simultaneous surface topography and wetting behavior changes upon abrasion of SHS. The process of physical abrasion was also simulated on the...

Fabrication and Characterization of Photolithographically Patterned Rough Surfaces Demonstrating Extreme Contact Angle Behavior
DownloadFall 2014
This thesis features experimental work done to fabricate and characterize silicon surfaces patterned using photolithographic techniques, both standard and novel, to produce a variety of surfaces with roughness of controlled geometric properties. In specific, one set of the surfaces fabricated...

Fall 2015
Drop transfer from one solid surface to another through stretching liquid bridges between them is important for many industrial applications. Due to the different dominate forces, three possible regimes exist: Quasi-static Regime, where the transfer process is only dominated by surface forces;...

Design and Construction of a Temperature Cell to Study the Effect of Temperature Rise on Particle-Drop Impact
DownloadFall 2013
An experimental device aimed at simulating interactions in a fluidization process was designed, built, and tested to allow future study of drop-particle impact at high temperatures. The design parameters were defined based on theoretical investigations. A feasibility study were developed using...

Understanding the Role of Surface Microgeometries on Wetting: Designing Robust Superhydrophobic Surfaces
DownloadSpring 2014
This thesis is concerned with effects of surface microgeometries on wetting, aiming at providing instructions for reproducing controllable wettability on artificial surfaces and designing robust superhydrophobic surfaces. First, the origin of edge effect is understood by a thermodynamic approach...

Spring 2013
For drops sessile on a solid surface, cross flowing air can drive drop oscillation or shedding, based on the balance and interaction of aerodynamic drag force (based on drop size/shape and air speed) and adhesion/capillary forces (based on surface tension and drop size/shape). Better...
