Investigation Of 12 Μm 4h-Sic Epilayers For Radiation Detection And Noise Analysis Of Front-End Readout Electronics, Khai V. Nguyen, Rahmi O. Pak, Cihan Oner, Feng Zhao, Krishna C. Mandal

Electrical and Computer Engineering Faculty Research & Creative Works

Schottky barrier radiation detectors were fabricated on 12 μm n-type 4H-SiC epitaxial layers grown on a 4° off-axis highly doped 4H-SiC substrate (0001). Schottky barrier junction properties were characterized through current-voltage (I-V) and capacitance-voltage (C-V) measurements. A diode ideality factor of 1.29 and Schottky barrier height of 1.10 eV were determined from the forward I-V characteristics using a thermionic emission model. A built-in potential of 1.91 V and effective carrier concentration of 1.03 x 10¹⁵ cm^-3 was calculated from a Mott-Schottky plot of the C-V measurements. Radiation detector performance was evaluated by alpha pulse height spectroscopy (PHS) in …

Direct Strength Prediction Of Cold-Formed Steel Beam-Columns, American Iron And Steel Institute

American Iron and Steel Institute (AISI) Specifications, Standards, Manuals and Research Reports (1946 - present)

The Direct Strength Method (DSM) of cold-formed steel member design employs local, distortional, and global cross-section elastic buckling analysis with empirically derived “direct” expressions to predict member strength. DSM is an accepted design method in national design specifications (e.g., AISI-S100-16) and enables a unified, robust, and flexible design approach. However, for beam-columns DSM in current design specifications employs simplified linear interaction expressions based on combining the isolated axial and bending elastic buckling and strength response. Today, local, distortional, and global elastic buckling under any combination of axial load and bending moments may be found using elastic buckling analysis tools such …

STAR Program Research Presentations

Licensing offshore oil and gas reserves in the United States waters are overseen by the U.S. Department of the Interior’s Bureau of Safety and Enforcement (BSEE). The licensing application includes planning for any worst-case oil spill scenario between BSEE and the applicant based on lessons learned from historic offshore spills such as the Deepwater Horizon (2010), Exxon Valdez (1989), and the Union Oil Platform Blowout (1969). The process for planning to respond to oil spills involves coordination with multiple agencies, trustees, and stakeholders to ensure that oil spill responses consider multiple factors, including ecologically sensitive species, commercial transportation and fisheries, …

Effect Of Surface Treatment On Liquid Adhesion Inside 3-D Structures, Madani A. Khan, Jeffrey Alston, Andrew Guenthner, Jacob Zavala

STAR Program Research Presentations

This study explores the relationship between chemical surface treatments on the interior of glass tubes and their resistance to fluid flow. By treating the interior of the tubes with functional silanes we can decrease or increase the interaction of the tube walls with the fluid column, which translates to changes in fluid column height for a given pressure differential. Resistance to fluid flow is quantified by using the tubes as integral parts of a barometric pressure column and measuring the changes in column height as the fluid is pulled into the tube by a set pressure differential. The barometric pressure …

Studying The Effects Of Serpentine Soil On Adapted And Non-Adapted Species Using Arduino Technology, Kiana Saniee, Edward Himelblau, Brian Paavo

STAR Program Research Presentations

Abstract: Serpentine soils are formed from ultramafic rocks and are represent an extreme environment for plants. Serpentine soils are unique in that they carry high concentrations of heavy metals, are nutrient deficient, particularly in calcium, and have poor water retention capabilities. Although these soils constitute harsh conditions for plant growth, there are a number of species that are adapted and even endemic to serpentine soil. Water retention by commercial potting mix was compared with serpentine soil. Also, serpentine adapted and non-adapted species were grown in both soil treatments and physiological data were collected. We used the Arduino electronic platform to …

Optimizing The Telescope Assembly Alignment Simulator For Sofia, Zoe E. Sharp, Alex Quyenvo, Jennifer Briggs, Brian Eney

Climate Change And The Delta, San Francisco Estuary And Watershed Science, Michael D. Dettinger, Jamie Anderson, Michael L. Anderson, Larry R. Brown, Daniel R. Cayan, Edwin P. Maurer

Civil, Environmental and Sustainable Engineering

Anthropogenic climate change amounts to a rapidly approaching, “new” stressor in the Sacramento–San Joaquin Delta system. In response to California’s extreme natural hydroclimatic variability, complex water-management systems have been developed, even as the Delta’s natural ecosystems have been largely devastated. Climate change is projected to challenge these management and ecological systems in different ways that are characterized by different levels of uncertainty. For example, there is high certainty that climate will warm by about 2°C more (than late-20th-century averages) by mid-century and about 4°C by end of century, if greenhouse-gas emissions continue their current rates of acceleration. Future precipitation changes …

The Risks Of Revolution: Ethical Dilemmas In 3d Printing From A Us Perspective, Erica L. Neely

Philosophy and Religion Faculty Scholarship

Additive manufacturing has spread widely over the past decade, especially with the availability of home 3D printers. In the future, many items may be manufactured at home, which raises two ethical issues. First, there are questions of safety. Our current safety regulations depend on centralized manufacturing assumptions they will be difficult to enforce on this new model of manufacturing. Using current US law as an example, I argue that consumers are not capable of fully assessing all relevant risks and thus continue to require protection any regulation will likely apply to plans, however, not physical objects. Second, there are intellectual …

Comparison Of Lean Construction In India And United States Of America, Vedangi Mahashabde

Masters Theses & Specialist Projects

The concept of Lean Construction has been introduced successfully into the Construction Industry to increase efficiency and profit by elimination of non-value adding activities or ‘Waste’. Lean Construction is an adaptation of Lean manufacturing principles and is the future of the Construction Industry in developing as well as developed countries. There has been much study and documentation conducted on ‘Lean Construction’ in USA. Even though people have started practicing Lean in India, there is lack of documented information available about it. Professionals within the Industry could already be minimizing ‘Waste’ and/or following Lean principles without the knowledge of the term …

An Unexpected Restructuring Of Combustion Soot Aggregates By Subnanometer Coatings Of Polycyclic Aromatic Hydrocarbons, Chao Chen, Xiaolong Fan, Tasneem Shaltout, Chong Qiu, Yan Ma, Andrew Goldman, Alexei F. Khalizov

Chemistry and Chemical Engineering Faculty Publications

We investigated the effect of thin polycyclic aromatic hydrocarbon (PAH) coatings on the structure of soot aggregates. Soot aerosol from an inverted diffusion burner was size classified, thermally denuded, coated with six different PAHs, and then characterized using scanning electron microscopy, light scattering, and mass-mobility measurements. Contrary to our expectation, significant restructuring was observed in the presence of subnanometer layers of pyrene, fluoranthene, and phenanthrene. These PAHs remained in subcooled liquid state in thin films, whereby the liquid layer acted as a lubricant, reducing the force required to initiate the restructuring. Thin layers of PAH of higher melting temperatures (perylene, …

Realizing Urban Water Pollution Impact In Melbourne, Australia Through Painting, Gregory Suplinskas

Independent Study Project (ISP) Collection

Throughout the month of November 2016, I undertook a creative environmental art project in Melbourne, Australia. I chose to create a water-soluble oil painting (dimensions 3 ft. x 4 ft.) that represents water pollution problems in the city of Melbourne, particularly in Port Phillip Bay. These problems include toxic stormwater runoff, plastics pollution and plastic nurdles, as well as nutrient buildup and algal overgrowth. The painting includes messages regarding sustainability; sustainable action limits the use of our natural resources so that humans can preserve the environment for future generations rather than degrade it. In the painting, I combine conceptual and …

Metal-Organic Hybrid Nanocomposites For Energy Harvesting Applications, Thulitha Madawa Abeywickrama

Masters Theses & Specialist Projects

Various synthetic methods have been developed to produce metal nanostructures including copper and iron nanostructures. Modification of nanoparticle surface to enhance their characteristic properties through surface functionalization with organic ligands ranging from small molecules to polymeric materials including organic semiconducting polymers is a key interest in nanoscience. However, most of the synthetic methods developed in the past depend widely on non-aqueous solvents, toxic reducing agents, and high temperature and high-pressure conditions. Therefore, to produce metal nanostructures and their nanocomposites with a simpler and greener method is indeed necessary and desirable for their nano-scale applications. Hence the objective of this thesis …
