Transmission Electron Microscopy Analysis Of Silicon-Doped Beta-Gallium Oxide Films Grown By Pulsed Laser Deposition, Cynthia Thomason Bowers
Transmission Electron Microscopy Analysis Of Silicon-Doped Beta-Gallium Oxide Films Grown By Pulsed Laser Deposition, Cynthia Thomason Bowers
Browse all Theses and Dissertations
Due to the large band gap of β-Ga2O3 and recent improvements toward high quality native substrates and the ability to shallow dope epitaxial β-Ga2O3 it is an attractive material for applications in power electronic devices. Such devices require advances in the areas of thin film growth and carrier concentration control to deliver high mobility films appropriate for the device structures. Transmission electron microscopy (TEM) analysis can provide information concerning doping, crystal structure, and internal strain which will be valuable to assess the role of defects and impurities on the transport properties for feedback to optimize the bulk and epitaxial growth …
Success Factors For Power Project Development Businesses In Sub-Saharan Africa, Kodjo Galevissi Afidegnon
Success Factors For Power Project Development Businesses In Sub-Saharan Africa, Kodjo Galevissi Afidegnon
Walden Dissertations and Doctoral Studies
Despite the financing gap in the sub-Saharan Africa power sector, private investors struggle to capitalize on the opportunity because of the high failure rate of power project development companies. Using the conceptual framework of the behavioral finance theory, this multiple case study was conducted to explore the strategies used by executives of 4 companies in sub-Saharan Africa who successfully developed power projects within the last 5 years. Data were collected from semistructured interviews and a review of government and institutions' websites. Yin's 5-phased cycle for analyzing case studies provided the guidelines for data analysis. Three themes emerged from data analysis: …

Strategies For Small Energy Consulting Business Survivability, Scholastica Nwabueze
Walden Dissertations and Doctoral Studies
Small businesses are critical to economic development. Small businesses create job opportunities and training and innovative products and services, but they encounter significant challenges and many fail in the first 7 years due to lack of sustainable strategies. The purpose of this single case study was to explore strategies owners used to sustain small energy consulting businesses for longer than 7 years. The population in this study consisted of 5 senior executives of a small energy consulting firm in the Washington, DC, metropolitan area. The conceptual framework for the study was the transformational leadership theory that deals with vision and …

Thermostable Phytase In Feed And Fuel Industries, Ushasree Mrudula Vasudevan, Amit Jaiswal, Shyam Krishna, Ashok Pandey
Articles
Phytase with wide ranging biochemical properties has long been utilized in a multitude of industries, even so, thermostability plays a crucial factor in choosing the right phytase in a few of the sectors. Mesophilic phytases are not considered to be a viable option in the feed industry owing to its limited stability in the required feed processing temperature. In the recent past, inclusion of thermostable phytase in fuel ethanol production from starch based raw material has been demonstrated with economic benefits. Therefore, considerable emphasis has been placed on using complementary approaches such as mining of extremophilic microbial wealth, encapsulation and …
