Show more"The huge demand for fossil fuels and the risks of the environmental crisis have spurred an interest in renewable energies. Using the clean and abundant solar energy, semiconductor photocatalysis and photovoltaics have evoked tremendous interest. Titanium dioxide (titania, TiO2) has been the focus of the research trend because of its excellent crystallinity, photoreactivity, chemical and thermal stability, and low cost. The research objective presented in this dissertation is to fabricate titania nanomaterials with tunable porosities, large surface area, unique morphologies, and enhanced capacities of adsorption, electron transport, diffusion, and then apply them in photocatalysis and photovoltaics. A modified non-hydrolytic sol-gel system with calcium carbonate templating was developed to create macro/micro/nano porous anatase titanium dioxide. The hydrolysis rate was lowered by chelating ligands of valeric acid for slow and sufficient precursor coating. CaCO3 was completely removed via acidification, resulting in titania powders with a surface area ranging from 197 to 239 m2/g. The templated TiO2 with a surface area of 239 m2/g and pore diameters of 6-109 nm showed a promising 27% photocatalytic improvement compared to commercial particles, and a 180% increase compared to template-free TiO2. This increase is attributed to the increased catalyst loading capacity and active photocatalytic sites. From hard templates to soft biodegradable natural templates, the rate-controlled sol-gel method was combined with homogenized micro/nano-fibrillated cellulose (MFCs) with an average diameter below 50 nm. Cellulose was removed completely by thermal treatment, and an in-situ coating technique created thin titania films on substrates with a porous structure. The degradation efficiency of the photocatalytic films was related to film thickness and to the Ti(IV)-to-cellulose ratio. Photocatalyst on film eliminated the post separation treatment related to powder catalyst and simplified the purification process. The sol-gel/MFCs precursor was also coated in-situ as the photoanode for dye-sensitized solar cells. It was found that the thickness of the anode film was a dominant factor to the overall performance and efficiency. The 6-layer cell showed a 400303% increase in solar-to-electricity efficiency (1.75%) compared to commercial paste at the same thickness under a simulated solar light irradiation of 100 mW cm-2 (AM 1.5). From non-hydrolytic to hydrolytic, a modified liquid phase deposition (LPD) approach was combined with MFCs. An optimized solvent composition of isopropanol/water ratio of 4 to 1 was found to yield coatings with uniform spherical TiO2 possessing a chain-like morphology oriented along the axis of the decomposed cellulose fibers. The average rate constant and degradation percentage were 0.72±0.09 min-1, 95% for TiF4-cellulose-4IPA1Water films, which increased by 1.88 times over the film prepared without cellulose templates due to the beneficial surface area, pore size, and the unique morphology. The three-dimensional web structure with pseudo one-dimensional sphere-chain could retard the recombination of photogenerated electron-hole pairs and improve the charge transport."--Pages ii-iii.

Show moreThis study reports the findings of a qualitative case study that examined how elements of design and organization were conceptualized and enacted in two graduate level online courses, and, how these conceptualizations and enactments evolved. Data was collected through interviews and ‘think-alouds’ with the course instructors and through screen captures of the course home pages. The Community of Inquiry Framework (CoI) (Garrison, Anderson, & Archer, 2000) was used as a lens to analyze the data for the Design & Organization element of the framework’s concept of Teaching Presence. The analysis identified patterns in the five features of the Design & Organization element: Setting Curriculum, Designing Methods, Establishing Time Parameters, Utilizing the Medium, and Establishing Netiquette. The data shows variation in the way most of the features are conceptualized and enacted in the online courses, with some exceptions. These variations reflect the different experiences, expectations, and logic of the two instructors, while the exceptions reflect the influence of external norming agents such as the Learning Management System or institutional guidelines. The results indicate a wider range of possibilities in course design and organization than the CoI framework has been conceptualized to account for, which has implications for the various programs and institutions using the framework as an instrument for their evaluation of online courses.

Title: Filtration of Phytophthora and Pythium zoospores in irrigation water
Creator: Jeon, Sangho
Date: 2017
Collection: Electronic Theses & Dissertations
Description: "Phytophthora and Pythium are commonly known as water molds, and can cause enormous damages to many floriculture and vegetable crops worldwide, including seedling damping-off, stunting, and crown, stem and root rot. It is challenging to control these pathogens because plants can be infected and do not show symptoms until the disease is too advanced to respond to treatment. The pathogens can also easily develop resistance to effective fungicides. As the zoospore movement with water flow is a...
Show more"Phytophthora and Pythium are commonly known as water molds, and can cause enormous damages to many floriculture and vegetable crops worldwide, including seedling damping-off, stunting, and crown, stem and root rot. It is challenging to control these pathogens because plants can be infected and do not show symptoms until the disease is too advanced to respond to treatment. The pathogens can also easily develop resistance to effective fungicides. As the zoospore movement with water flow is a major transmission pathway of these pathogens, understanding the transport of zoospores in natural and engineered systems is critical to developing strategies to control the pathogens in both field and greenhouse crops. Thus, the first study investigated the transport and retention of Phytophthora. capsici zoospores in saturated columns packed with iron oxide coated sand (IOCS) or uncoated sand in Na+ or Ca2+ background solution at pH 7.2 or 4.4, in combination with XDLVO interaction energy calculations and microscopic visualizations. Significantly more encysted zoospores were retained in IOCS than in uncoated sand, and at pH 4.4 than at pH 7.2, which likely resulted from increased electrostatic attraction between zoospores and grain surface. At pH 7.2, up to 99% and 96% of the encysted zoospores were removed in IOCS and uncoated sand, respectively, due to a combination of strong surface attachment, pore straining, and adhesive interactions. Motile biflagellate zoospores were more readily transported than encysted zoospores, thus posing a greater dispersal and infection risk. The second and third studies were conducted in a greenhouse to demonstrate a proof-of-concept of using fast-flow filtration to control Phytophthora and Pythium diseases in greenhouse floriculture and vegetable crops. The second study showed that Pythium aphanidermatum could be effectively removed by the fast-flow sand and AC filters at low water pressure. The rapid sand filter had the best performance because no decrease in the poinsettia quality was observed when compared to the non-inoculated control plants. Because the AC filter could also remove the essential nutrients from the irrigation water, and cause the Fe deficiency in the poinsettias, it is less desirable to be used unless the nutrients can be supplied separately instead of through irrigation water. The third study found that the filter with iron oxide coated media [IOCM] could effectively protect the squash plants from Phytophthora capsici, but caused the nutrient deficiency in the squash. The sand filter could not prevent, but only slow the disease development in the squash. Again, it shows that the IOCM filter has the potential to be used in treating irrigation water in the greenhouse vegetable production, but sufficient nutrients also need to be provided. Overall, the results suggested that physical removal of pathogens using fast-flow filtration can overcome many limitations of fungicide application, and may be a promising alternative for disease management in greenhouses."--Pages ii-iii.

Title: Resistance is not futile : exploring user resistance in technical communication

Show moreDespite ongoing investments to technology and usability in technical communication—and despite ongoing commitments to humanistic perspectives concerning those two domains—scholars of technical communication have yet to explore the topic of “user resistance” explicitly. User resistance gained prominence in fields like Information Technology (IT), Management Information Systems (MIS), and related fields and has traditionally been conceptualized as oppositional, hostile, or adversarial—a phenomenon meant to be avoided before it occurs. Because of this, traditional definitions of user resistance value the systems with which users engage, with little work theorizing the contexts, behaviors, and agencies of actual users. My dissertation responds to this lack of a user-centered approach by offering a thick literature review that examines how resistance is defined and situated across a range of scholarship. From this literature review, I offer a theory of user resistance that draws on the concept of “everyday resistance” (Vinthagen & Johanssen, 2012) to value users and their contexts. By situating the work done on resistance and providing a theoretical concept of user resistance, I then rhetorically analyze two examples of user resistance on the social networking site, Tumblr to illustrate how and why users resist in dynamic online spaces. The first example demonstrates how users resist within a system to design changes and the second illustrates the how users resist systems of power and oppression created and upheld (implicitly and explicitly) by the site developers and designers. Through an analysis and discussion of these examples, my dissertation seeks to start conversations about user resistance in the domain of technical communication and pivot existing conversations outside the field from a negative phenomenon meant to be avoided before it occurs, to a productive area of inquiry for technology design. Ultimately, I argue that attending to user resistance allows for a more nuanced and engaged approach to user-centered, participatory, and ethical design principles. By examining user resistance, technical communication researchers and practitioners can attend to the local, contextual, and most importantly dissonant needs of users.

Show moreThe Limits of Sympathy intervenes in the scholarly conversation surrounding the relationship between philanthropic reform and the novel as well as the role of women in philanthropic work during late Victorian England. Importantly, this project brings archival texts, such as the philanthropic case reports of the Charity Organisation Society, into the conversation in order to demonstrate how the professionalization of philanthropy eliminated the role of sympathy in philanthropic work and narrative. Where philanthropic texts created new narrative forms to grapple with the New Poor Laws and the changing urban environment of late Victorian London, novels by George Eliot, Walter Besant, H. G. Wells, Edith Johnstone, and Isabella Ford considered how the adoption of professionalized, distanced discourse affected women's perception of and participation in philanthropic work. These novels demonstrate how our current critical reliance on sympathy as a way to mediate the relationship between philanthropic and poor characters, as well as between reader and novel, no longer works within the context of professionalized philanthropy. -- Abstract.

Show moreThis dissertation describes the ways in which the securitized secular laws of the state act to regulate and control Muslims and the practices of Islam through "terrorism" prosecutions in the United States. In order to eliminate terrorism violence, the security state has created an exception to regular legal norms by establishing a court within a court and a prison within a prison, where normal legal procedures are not followed for those Muslim immigrants and American Muslim citizens accused of "terrorism" related offenses. I address the ways in which Muslims have been conditioned and affected by the securitized secular laws that are applied in "terrorism" cases, and I also discuss how human-rights advocacy around the accused challenge and resist these discriminatory practices. Based on 24 months of ethnographic fieldwork; observations of federal terrorism trials; a review of prison writings; and interviews with families of the accused, activists, lawyers, and human-rights advocates, I address the legal practices of securitized laws concerned with preventing "terrorism," their impact both inside and outside of judicial institutions, and the power of these practices on the lived experiences of Muslim Americans. While some authorities claim that preventive "terrorism" prosecutions are necessary to eradicate violence, I suggest that the main concerns of the security state are really about eradicating religious thought and practices that contradict the secular definition of acceptable religion. -- Abstract.
