This thesis describes the fabrication and characterization of integrated hollow Bragg waveguides fabricated by controlled thin film buckling. Hollow waveguides based on two different set of materials were studied. In the first case, thermal tuning of air-core dimensions was studied using...
The field of plasmonics has offered the promise to combine electronics and photonics at the nanometer scale for ultrafast information processing speeds and compact integration of devices. Various plasmonic waveguide schemes were proposed with the potential to achieve switching functionalities and...
Benign-by-Design: Synthesis of Engineered Silicon Nanoparticles and their Application to Oil Sands Water Contaminant RemediationDownload
Oil sands are naturally occurring mixtures of sand or clay, water, fine silts, and bitumen. The oil sands extraction process consumes large volumes of water (i.e., ca. 3 barrels of fresh water for every 1 barrel of oil). Following the extraction of bitumen from the oil sands, a tailings slurry...
Aquatic organisms are susceptible to waterborne nanoparticles and there is only limited understanding of the mechanisms by which these emerging contaminants affect biological processes. The unique properties of nanomaterials necessitate evaluation of standard toxicity testing techniques to...
SEM Images of Block Copolymer Templated Patterns from PS-b-P2VP on Silicon with Platinum for Testing with ADAblock
SEM Images of Block Copolymer Templated Patterns from PS-b-P2VP on Silicon with Platinum for Testing with ADAblockDownload
Scanning electron microscope (SEM) images of patterns derived from polystyrene-block-poly(2-vinylpyridine), where the poly(2-vinylpyridine) domains replaced with platinum metal. All samples were annealed for 20 minutes at 200 degrees celsius. Polymers used include PS(23.6k)-b-P2VP(10.4k),...
This thesis is focused on the Si-based anode materials for lithium-ion batteries (LIBs) as well as biomass-derived carbons for LIBs and sodium-ion batteries (NIBs). In our first attempt we investigated the effect of the support growth substrate as well as of aluminum coating layers on the...
Silicon nanocrystals (SiNCs) have been suggested as promising candidates for bioimaging because of their abundance, biocompatibility, and stable photoluminescent properties. However, “naked” SiNCs are insoluble in water and very reactive. As a result, NC surface functionalization is necessary to...
This thesis focuses on the photoluminescence (PL) of free-standing silicon quan- tum dots (QDs). Large changes in the emission spectrum were found to occur when the QDs were exposed to different environments while undergoing short-wavelength laser irradiation, a phenomenon that was the main focus...
Dangling Bonds (DBs) on the silicon surface exist when a silicon atom lacks a bonding partner, resulting in a localized orbital which is not involved in any chemical bonds. On the hydrogen-terminated Si(100) surface, such DBs introduce a mid-gap state. DBs can be created on this surface by the...
This thesis is focused on the silicon-based anode materials for lithium-ion batteries (LIBs) as well as germanium-based electrode materials for sodium-ion batteries (NIBs). In our first attempt we studied electrochemical cycling stability and degradation mechanisms of silicon nanowires (SiNWs)...
