- Description:
- Under the correct conditions, aluminum can be anodized in an electrochemical cell to produce hexagonally ordered arrays of nanoscale pores. This study examines how adding the chemicals methanol and acetic acid to a typical anodization solution alters pore-growth patterns across the surface oxide layer. The existence of the unique pore-growth...

- Cadmium selenide (CdSe) quantum dots have low conductivity upon synthesis with the original capping ligands. The conductivity can be altered by the addition of other ligands. Thiols, amines, and carboxylic acids, as well as other functional groups, have been shown to improve conductivity in quantum dot films. This investigation describes...

- Surface patterns, formed by the coassembly of cationic-anionic amphiphiles into cylindrical micelles, were analyzed. The competition between electrostatic forces and the net incompatibility χ arising from the different chemical natures of those oppositely charged amphiphiles resulted in the formation of segregated domains. These surface domains are not macroscopically segregated due...

- Description:
- Recent research suggests that ultraviolet illumination is essential for the creation of monolayers of Undecylenic Acid Methyl Ester (UDAME), as it is believed that the UV illumination initiates the radical-chain polymerization. Samples created without UV illumination, however, also show signs of a monolayer. In this study, samples were analyzed using...

- Description:
- The development and applications of organic/DNA molecules for the use of DNA detection systems are reported here. In particular, two different hybrids are synthesized: DNA/polymer hybrids and small-molecule DNA hybrids. DNA/polymer hybrids are especially useful considering that their functionality may be varied according to the polymer selected. The hybrids are...

- Description:
- Several phosphonate-functionalized molecular squares have been successfully synthesized, and the fabrication of multilayer films on both conductive and semiconducting platforms has been demonstrated. These films were grown using the well-documented zirconium phosphonate multilayer method. The layer-by-layer growth rate is uniform. Experiments suggest, however, that the molecular squares adopt a semi-collapsed...

- Description:
- Anthony Braxton’s Trillium J, part of an ambitious planned “complex” of 36 one-act operas, premiered in 2014. Very little writing—anecdotal, journalistic, nor scholarly—exists on these works, so this research provides a critical introduction, contextualizing the operas within Braxton’s oeuvre and discussing the works’ fundamental musical materials and organization. Examples from...

- Studies on consolidated democracies have long concluded that there is a positive relationship between socioeconomic status and turnout. The strength of the empirical findings that linked electoral participation to socioeconomic variables elevated this correlation to a law-like principle and made it possible to assume that this electoral behavior would prevail...

- Homotopy Gerstenhaber structure is shown to exist on the deformation complex of a morphism of associative algebras. The main step of the construction is extension of a B-infinity algebra by an associative algebra. Actions of B-infinity algebras on associative and B-infinity algebras are analyzed, extensions of B-infinity algebras by associative...

- Theoretical studies on electronic structure governing charge transport properties are investigated to understand and improve the prediction of electron charge carrier organic semiconductors used in field-effect transistors. Perfluorinated oligothiophene semiconductors have shown experimental n-type behavior, but placement of fluorinated aryl groups changes charge polarities. Models were developed to investigate how...
