Diversifying Nuclear Technology: A Technical Analysis On Small Modular Reactors And Its Impact On Nuclear Energy Policy, Carolina Lugo Mejia, Marcos Lugo
Helm's School of Government Conference - American Revival: Citizenship & Virtue
The energy policy debate in the United States has revolved around the diversification of energy sources while promoting advantageous economic profits. One drive for this has been the discussion of anthropogenic, environmental endangerment concerns (Vlassopoulous 2011, 104). However, despite the environmental concerns, the U.S. has for some time only relied on one type of energy source—fossil fuels. Fossil fuels are categorized as natural gas, coal, petroleum, and other gases responsible (U.S. Energy Administration 2019). Natural gas is responsible for 38.4%, coal for 23.4%, petroleum for 0.4%, and other gases for 0.3% of the U.S.’s electrical generation (U.S. Energy Administration 2019). …

Aspen Plus was used to simulate the ethane steam cracking reactor and other process units. Sensitivity analysis was performed to determine the most efficient and cost-effective operation regarding product yield. The results show that the maximum …
Electronic Effect Of Platinum Alloy Catalysts On Olefin Hydrogenation Kinetics, Colin Reedy, Jeff Miller, Stephen Purdy
Electronic Effect Of Platinum Alloy Catalysts On Olefin Hydrogenation Kinetics, Colin Reedy, Jeff Miller, Stephen Purdy
The Summer Undergraduate Research Fellowship (SURF) Symposium
Dehydrogenation of alkanes is the first step in transforming light hydrocarbons into liquid fuels and chemicals. This process has traditionally used platinum alloys as catalysts. Alloys are used industrially because they have a greater selectivity than monometallic platinum. Alloying platinum with an inactive promoter modifies the crystalline structure of the surface (geometric effect), and the 5d electrons in platinum responsible for chemistry (electronic effect); both have been suggested to be primarily responsible for dehydrogenation selectivity in platinum alloys. Alloy catalysts have been synthesized using early 3d transition metal promoters with the same Pt3M crystal structure. X-Ray Absorption Spectroscopy …

Metabolic Comparison Of Wild-Type And Transgenic Synechocystis Pcc 6803 Cyanobacteria, Ian A. Mcluckey, John A. Morgan, Joel Yu King Hing
The Summer Undergraduate Research Fellowship (SURF) Symposium
The Calvin-Benson (CBB) cycle is an essential part of nature. This phenomenon allows carbon molecules in carbon dioxide from the atmosphere to be converted into useful energy in the form of sugars. Cyanobacteria are single-celled organisms capable of utilizing energy from sunlight to drive this cycle and are also readily engineered. In hopes of improving this cycle, we compared a wild-type version of the Synechocystis PCC6803 cyanobacteria to an engineered version overexpressing the enzyme FBA (fructose-biphosphate aldolase), called 70 glpX, to deduce how the overexpressing strain is able to be more photosynthetically efficient. To do this, comparative metabolomics were done …

Dynamic Behavior Of A Clamped-Clamped Bi-Stable Laminate For Energy Harvesting, Ajay V. Kumar, Andres F. Arrieta Ph.D., Myungwon Hwang
Dynamic Behavior Of A Clamped-Clamped Bi-Stable Laminate For Energy Harvesting, Ajay V. Kumar, Andres F. Arrieta Ph.D., Myungwon Hwang
The Summer Undergraduate Research Fellowship (SURF) Symposium
Multi-stable laminates have many applications in morphing structures, energy harvesting devices, and metamaterials due to the specific characteristics attributed to the exhibited stable states. Changes between stable states allow for large deflections, on-demand variation of the stiffness of compliant structures embedded within these elements, and control of effective dynamic properties in periodic lattices. These changes in state can be accessed via a snap-through instability triggered by introducing a well-defined activation energy. The resulting oscillations could enable broadband energy harvesting via piezoelectric transduction and resistive circuits. In this paper, a clamped-clamped bi-stable laminate is studied to understand the behavior of the …

Photolithography In Fabrication Of Thin-Film Solar Cells, Yusheng Zhu, Rakesh Agrawal
The Summer Undergraduate Research Fellowship (SURF) Symposium
Solar energy has steadily increased its efficiency and cost-effectiveness throughout the past three decades and seems poised to compete with current primary energy (natural gas, oil, coal) as the need for alternative energy sources rises. One type of solar cell, thin-film cells, often relies on use of permanent photomasks in order to imprint a pattern onto the front metal contact. However, these machined metal masks are rigid and do not allow for different designs to be explored as current masks encounter difficulties in machining grids thin enough for optimization. Photolithography, traditionally used in the microfabrication field, provides a method in …

Environmental Monitoring In Preparation For The Installation Of A Green Roof, Andrew N. Martin, Ming Qu
The Summer Undergraduate Research Fellowship (SURF) Symposium
Green roofs are becoming an increasingly popular way to improve the environmental, economic, and aesthetic performance of both new and existing buildings. Along with the green roofs themselves, it is also common to install sensors to measure various environmental parameters that are affected by or important to the operation of the roof such as precipitation, temperature, and runoff. However, for most of these systems, the sensors are installed at the same time or even after the green roof. Therefore, no before-and-after comparisons can be made for those roofs. To account for this missing data, monitoring equipment was installed on a …
