LARGE AREA 3D PHOTONIC CRYSTALS WITH EMBEDDED WAVEGUIDES
A crystal is a periodic and repeating arrangement of atoms or molecules. Photonic crystals are structures with periodic variations in the dielectric constants that manipulate and control the properties of light propagation. Photonic crystals are analogous to semiconductor crystals with periodic …

Large-area visually augmented navigation for autonomous underwater vehicles
This thesis describes a vision-based, large-area, simultaneous localization and mapping (SLAM) algorithm that respects the low-overlap imagery constraints typical of autonomous underwater vehicles (AUVs) while exploiting the inertial sensor information that is routinely available on such platforms. …

Electrical characterization of large-area donor-acceptor molecular junctions
… of five different donor – bridge – acceptor large-area monolayer molecular junctions show current rectification. Langmuir-Blodgett deposition onto thermally evaporated gold yielded four out of the five monolayers. The fifth system was as a monolayer formed by self-assembly onto …

Solid state superionic stamping design for large area patterning
… stamps were examined. One goal was to produce larger diameter stamps without resorting to extensive waste of Ag2S. The ductile nature of the material was exploited to change the geometry of the material to increase the portion of the stamp actively participating in etching metal. These larger …

Large area cellulose nanocrystal self-assembly: towards sustainable pigments
… neglects the limitations and challenges posed by large-scale and continuous processes which are prevalent in industrial contexts. In this thesis, I demonstrate how the self-assembly of CNCs can be precisely controlled to produce meters-long films using a roll-to-roll (R2R) equipment. Starting with …
