Current biofuel technologies utilize valuable foodstuffs, such as corn kernels and cane sugar, as sources of easily metabolized sugars. Microbes are used to ferment these sugars into bioethanol, a first-generation biofuel. However, in order to avoid diverting foodstuffs from the food supply, the development of second-generation biofuels technology is necessary. Second-generation biofuels are produced by converting structurally complex lignocellulosic biomass, such as agricultural and municipal wastes, to fermentable sugars or directly to biofuels.
The major technological hurdle limiting the mass production of second-generation biofuels is the difficulty in efficiently converting structurally complex lignocellulosic materials to fermentable sugars or directly to …

Global Warming: At What Point Does Atmospheric Greenhouse Gas Release Become Unethical?, Luke Good, Gladys Lopez
Festival of Communities: UG Symposium (Posters)
In recent decades, the concept of global warming has developed increasing concern among the scientific community and general public alike. What was initially dismissed as little more than unlikely has now become a severe warning for global climate crisis threatening not only our way of life but ultimate future existence on this planet? Global warming is defined as the steady mean increase in atmospheric temperature, the primary asserted cause thereof being increased emissions and inherent atmospheric concentrations of “greenhouse gases” – carbon dioxide in particular. These gases contribute to the greenhouse effect by trapping radiation (from the sun) in the …

Energy Densification Via Hydrothermal Carbonization, Keri Noack
Festival of Communities: UG Symposium (Posters)
A process called hydrothermal carbonization (HTC), also known as wet torrefaction involves treatment of raw biomass in hot, pressurized water. HTC of woody biomass has been shown to significantly increase the energy density of the feedstock, producing a biochar, similar to coal, having up to 40% higher calorific energy content. Feedstocks investigated include Tahoe chips, Pinion/Juniper chips, Rice hulls, and Corn Stover pellets pre-treated at 215 °C, 255 °C, and 295 °C. Chemical analyses were conducted on the gaseous, aqueous, and solid HTC products. Energy contents of the solid biochar products were measured by calorimetry, and mass balances were determined.
Exploring The Potential Of Agave As A Biofuel Crop On Arid Land, Rhea Conlu, Diana Ha, Jeffery Shen
Exploring The Potential Of Agave As A Biofuel Crop On Arid Land, Rhea Conlu, Diana Ha, Jeffery Shen
Festival of Communities: UG Symposium (Posters)
Worldwide awareness of global warming and depleting fossil fuel sources has made research into alternative resources, such as plant fuels imperative. Since groundwater irrigation is unsustainable, especially in desert climates, plants that are drought resistant or can utilize otherwise unusable water are more viable sources of future biofuel production. Agave nevadensis, a species belonging to the family Agavaceae are succulent plants native to Las Vegas. This experiment aims to expose A. nevadensis to both wastewater and drought conditions and observe its response. The results can help define Agave as a water-resourceful biofuel both tolerant of drought and capable of utilizing …

Thin-Film Fabrication For High Pressure Thermoelectric And Electrical Resistivity Studies, Jorge L. Reynaga, Rama Venkat, Ravhi S. Kumar
Festival of Communities: UG Symposium (Posters)
Thermoelectric materials are of interest for application such as thermoelectric cooler in microprocessors and power generators in cars. High pressure plays an important role in understanding the changes in the figure of merit of thermoelectric thin films. To study the thermoelectric thin films a direct approach is to fabricate the thin film on the surface of a diamond anvil, so that the pressure dependence of structure and transport properties can be investigated easily. If we could successfully fabricate the electrical probes by depositing thin films, then it reduces the use of electrical wires as probes inside the diamond cell, as …

Oral Presentation: Next Generation Nuclear Fuels, Douglas Hanks
Festival of Communities: UG Symposium (Posters)
Zirconium carbide has been proposed as a coating layer for next generation (“TRISO”) nuclear fuel, and is intended as a diffusion barrier to contain fission products (e.g., Pd). To study the chemical interaction between Pd and ZrC, their interface was investigated using X-ray Photoelectron Spectroscopy (XPS). Pd was step-wise deposited onto ZrC in ultra-high vacuum, and the chemical interaction at the interface was monitored, also as a function of temperature (up to 1000 C). In the presentation, details of the chemical interaction and changes in the chemical environment of Pd and their relevance for TRISO fuel will be discussed.

North American Energy Water Nexus Roundtable
The North American Energy-Water Nexus roundtable was held April 1, 2011, to promote the discussion of how energy and water issues converge in addressing international relations. The roundtable focused on water issues specific to the U.S.-Mexico and U.S.-Canada borders, including stakeholder-driven solutions for water policies and water technologies. The event was co-sponsored by the UNLV Urban Sustainability Initiative; Desert Research Institute; the Canadian Consulate of Los Angeles; and the government of Ontario, Canada.
