The Artificial Leaf: An Investigation Into The Sociotechnical Integration Of New Solar Energy Innovations, Alexandra K. Treml, Jamie M. Mears

Senior Honors Projects, 2020-current

Increasing global demand, combined with the volatility of fossil fuels, has called for a large-scale increase in renewable energy production. Photovoltaics hold significant potential, but by nature, solar energy is intermittent and lacks dispatchability. Researchers around the world are working to create innovative solutions that utilize semiconductors found in solar cell technologies in new ways. This project harnesses photoelectrochemical water-splitting, which uses light energy to dissociate water molecules into hydrogen and oxygen. When the water-splitting device is submerged in saltwater and illuminated by sunlight, oxygen and hydrogen gas are produced on opposite surfaces, and can be either released or stored …

Economics Of R&D Specialization In The Semiconductor Industry, Kyun Kim

Legacy Theses & Dissertations (2009 - 2024)

Starting in the 1970s, specialized suppliers have entered the semiconductor industry to supply capital equipment, or tools, used in semiconductor manufacturing to downstream semiconductor companies. After the entry of these external suppliers, semiconductor chip producers began to rely in varying degrees on them for the R&D to improve the quality of capital equipment, while they themselves began to focus on design and production of chips. In my dissertation, I conduct an empirical and theoretical investigation to support my hypothesis that the difference in R&D incentives between the upstream suppliers and downstream chip manufacturers was the important reason for the emergence …

Role Of Group Ii Metabotropic Glutamate Receptor Subtype 2 (Mglur2) In Appetitive And Consummatory Aspects Of Ethanol Reinforcement, Kyle Allyson Windisch

Open Access Dissertations

Background: Group II metabotropic glutamate receptors (mGluR2/3) are predominately presynaptically located G_i/o coupled receptors that are highly expressed in the cortex, nucleus accumbens, amygdala, and hippocampus. Previous studies suggest that group II mGluRs are involved in regulating ethanol (EtOH) consumption and seeking following extinction (Backstrom and Hyytia, 2005; Kufahl, et al., 2011). The sipper tube model, which allows for procedural separation of seeking and consumption, was used to further clarify the role of mGluR2/3 in EtOH-seeking and consumption. The non-selective group II mGluR agonist LY379268 (LY37) and selective mGluR2 positive allosteric modulator (PAM) BINA were used to determine the …
