N2, O2, and NF3 Dissociation in a Low Frequency, High Density Plasma Source
(2017-08)Radical densities and gas dissociation fractions were measured by optical emission spectroscopy (OES), combined with Ar actinometry for various mixes of N2, O2, and NF3 feed gases with Ar at 400 sccm total flow rate in a ... -
Naimark's Problem for Graph C*-Algebras
(2017-05)Naimark’s problem asks if a C*-algebra with exactly one irreducible representation up to unitary equivalence is isomorphic to K(H), the algebra of compact operators on some Hilbert space H. A C*-algebra that satisfies the ... -
Nanofluid of Graphene-Based Amphiphilic Janus Nanosheets for Oil Recovery
(May 2018)Since our primary energy transition still remains uncertain, fossil fuel energy would still be our dominant energy resource for decades to come. One of the main components of fossil fuel is crude oil. Chemical flooding is ... -
Nanoindentation Based Estimates of Flexoelectric Properties of Piezoelectric Crystals
(2012-05)Flexoelectricity refers to coupling between electric polarization and strain gradients in crystalline dielectrics. Recent work has shown that stiffness data obtained by nanoindentation, combined with an analytical indentation ... -
Nanomaterials to Enhance the Performance of Thermoelectric Materials and Catalysts for Water Splitting
(2019-05)Solutions to the growing energy demand and environment concerns can be increasing the current energy conversion efficiency or seeking alternative energy sources. Thermoelectric materials can directly harvest and convert ... -
NANOPARTICLES TRANSPORT THROUGH POROUS MEDIA FOR ENHANCED OIL RECOVERY
(2012-05)Application of nanoparticles is envisaged for enhanced oil recovery applications because of their unique transport and surface wettability properties along with their relatively small sizes compared to the size of pores ... -
Nanostructured Polymer Films for Electronics
(2014-05)Nanostructured polymer films are used as active materials in polymer-based photovoltaics, and as sacrificial materials for building nanoscale semiconductor devices. The research work described in this thesis addresses both ... -
NANOSTRUCTURED SURFACES AND EMERGENT PHYSICAL BEHAVIOR
(2012-05)Due to larger surface to volume ratio, surfaces play a significant role at the nanoscale. Surface atoms have different coordination numbers, charge distribution and subsequently different physical, mechanical and chemical ... -
Nanotechnology and Biotechnology for Water Treatment: A Comparative Study
(2014-08)In 2012, the World Health Organization estimated that about 11% of the world’s population does not have access to clean water and about 1.6 million deaths are caused by contaminated water annually. Even though there are ... -
Narrative Analysis of Beethoven's Piano Concerto No. 5
(2015-05)The Piano Concerto in E-flat Major, op.73, completed in 1811, represents Beethoven's fifth and final contribution to this genre. This paper investigates the first movement of the Fifth Piano Concerto in light of the heroic ... -
Narrative Analysis of Paul Hindemith's Sonata for Harp
(December 2)Hindemith’s Sonata for Harp is a three-movement work with a poem by Ludwig Heinrich Christoph Hölty attached to the third movement. The first and second movements are presented as Type 3 sonata forms with romance archetypes. ... -
Narrative and Myth in Bartók's Sixth String Quartet: A Study in the Poetics of Space and the Grotesque
(December 2)Bartók’s Sixth String Quartet is known for its return to more conservative tonal, formal, and generic idioms. Setting it apart, however, is the pervasive role of the ritornello that precedes each movement and increases in ... -
Narratives of Contemporary Africa on China Global Television Network’s Documentary Series Faces of Africa
(Journal of Asian and African Studies, 3/27/2018)This paper examines the documentary series Faces of Africa, broadcast on CGTN Africa, the African branch of China Global Television Network (CGTN, formerly known as CCTV International) since 2012. Using in-depth interviews ... -
Nascent Hue
(2019-05)Maggie Nelson writes in, Bluets, "There are no instruments for measuring color; there are no 'color thermometers.' How could there be, 'color knowledge' always remains contingent upon an individual perceiver." That Nascent ... -
Native Plant-Based Phytoremediation of Atrazine in Surface Waters Using a Floating Raft System
(December 2)Water systems in the 21st century have improved drastically compared to historical precedents due to the implementation of multi-stage treatment systems. In spite of such progress, issues with contamination still remain. ... -
Natural and Anthopogenic Carbonaceous Materials for the Remediation of Polychlorinated Biphenyls from Aqueous Solution
(2013-08)The presence of polychlorinated biphenyls (PCBs) in the environment is a continuing challenge that presents a hazard to ecosystems and human health. The proliferation of carbon-based nanomaterials such as graphene (GE) and ... -
