Neutron Diffraction Of Nabd4: Phase Transition, Rietveld Structure Refinements, And Equation Of State, Guillermo Esparza, Esparza, Patricia Kalita, Andrew Cornelius

Undergraduate Research Opportunities Program (UROP)

NaBH4 is a hydride with possible applications as a hydrogen storage material for future renewable energy technologies. It’s dehydrogenation properties are enhanced with the mixture of particular catalysts through ball-milling techniques during which local pressures may exceed several GPa’s. It is for this reason that understanding the behavior of pressure induced phase changes of its crystalline unit cell is an area of interest.

Novel Thermophilic Cellulolytic Isolates Belonging To The Phylum Chloroflexi, Maryknoll Palisoc, Jessica K. Guy, Joseph P. Peacock, Duy C. Trinh, Jeremy A. Dodsworth, Brian P. Hedlund

Undergraduate Research Opportunities Program (UROP)

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 …

The High Costs Of Conserving Southeast Asia's Lowland Rainforests, Brendan Fisher, David P. Edwards, Xingli Giam, David S. Wilcove

Rubenstein School of Environment and Natural Resources Faculty Publications

Mechanisms that mitigate greenhouse-gas emissions via forest conservation have been portrayed as a cost-effective approach that can also protect biodiversity and vital ecosystem services. However, the costs of conservation - including opportunity costs - are spatially heterogeneous across the globe. The lowland rainforests of Southeast Asia represent a unique nexus of large carbon stores, imperiled biodiversity, large stores of timber, and high potential for conversion to oil-palm plantations, making this region one where understanding the costs of conservation is critical. Previous studies have underestimated the gap between conservation costs and conversion benefits in Southeast Asia. Using detailed logging records, cost …

Morphology Changes In Pcpdtbt:Pcbm And P3ht:Pcpdtbt:Pcbm And Its Effect On Polymer Solar Cell Performance, Galen David Cauble

Physics

Polymer solar cell morphology is sensitive to both heat and time. By thermally annealing polymer solar cells the morphology of the devices can be altered causing immediate changes in device performance. Blending PCPDTBT:PCBM with P3HT:PCPDTBT combines the absorption characteristics of each to create a more even absorption spectrum. Subjecting PCPDTBT:PCBM, and P3HT:PCPDTBT:PCBM polymer solar cells to thermal annealing as well as recording device performance through time has shown that P3HT:PCPDTBT:PCBM devices react positively to thermal annealing (increasing from 0.8% to 1.4%) while PCPDTBT:PCBM devices have varied reactions. Furthermore, the P3HT:PCPDTBT:PCBM devices have achieved efficiencies of 1.6% in AM 1.5 compared …

Development Of A Sustainable Water Resource Financing Mathematical Model For Donors And End-Users, Sahar Zavareh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rural villages and underdeveloped communities represent the largest group challenged by poor water supply and sanitation with inequalities in resources to adequately implement potential solutions and even more with their high risk level of financing, funding is particularly challenging for water projects. Innovative financing alone will not eliminate the burdens of rural villages and underdeveloped communities. The purpose of this thesis is to address the lack of sustainable water financing of water projects in rural areas using a novel framework of a mathematical model based on "system dynamics" using optimal feedback control theory to maximize the performance of a water …

On The Ethical Possibility Of Sustainability: A Challenge For Higher Education, Eric Bain-Selbo

Education for Sustainability Summer Institute

At the heart of the sustainability movement are two questions central to its viability: Are human beings capable of treating the Earth ethically? Are human beings capable of acting morally responsibly for the benefit of distant future generations? Answers to both questions are unclear. This paper draws upon the work of 20^th century critical theorists to identify the ethical core of these questions. In the process, the paper will show what would be necessary for us to answer these questions affirmatively. The paper concludes with reflections about how higher education, and interdisciplinary inquiry in particular, can be critical to …

Inequality, Communication And The Avoidance Of Disastrous Climate Change In A Public Goods Game, Alessandro Tavoni, Astrid Dannenberg, Giorgos Kallis, Andreas Loeschel

Alessandro Tavoni

International efforts to provide global public goods often face the challenges of coordinating national contributions and distributing costs equitably in the face of uncertainty, inequality, and free-riding incentives. In an experimental setting, we distribute endowments unequally among a group of people who can reach a fixed target sum through successive money contributions, knowing that if they fail they will lose all their remaining money with 50% probability. In some treatments we give players the option to communicate intended contributions. We find that inequality reduces the prospects of reaching the target, but that communication increases success dramatically. Successful groups tend to …

Planning Approaches For Water Resources Development In The Lower Mekong Basin, Robert Costanza, Ida Kubiszewski, Peter Paquet, Jeffrey King, Shpresa Halimi, Hansa Sanguanngoi, Nguyen Luong Bach, Richard Frankel, Jiragorn Ganaseni, Apisom Intralawan, David Morell

Institute for Sustainable Solutions Publications and Presentations

Governments in the Lower Mekong Basin (LMB) face decisions that involve trade-offs between, for example, the economic benefits from hydropower generation and potentially irreversible negative impacts on the ecosystems that provide livelihoods and food security to the rural poor. These decisions involve complex problems that are both poorly understood in scientific terms and subject to rapid, potentially catastrophic change over time. A comprehensive, whole systems approach that adequately addresses the risks and uncertainties involved is necessary, but this is a daunting challenge for researchers, decision makers, and managers. They must develop the capacity to plan, coordinate, and implement a program …

Variable Renewable Energy In Modeling Climate Change Mitigation Scenarios, Falko Ueckerdt, Robert J. Brecha, Gunnar Luderer, Patrick Sullivan, Eva Schmid, Nico Bauer, Diana Böttger

Physics Faculty Publications

This paper addresses the issue of how to account for short‐term temporal variability of renewable energy sources and power demand in long‐term climate change mitigation scenarios in energy‐economic models. An approach that captures in a stylized way the major challenges to the integration of variable renewable energy sources into power systems has been developed. As a first application this approach has been introduced to REMIND‐D, a hybrid energy‐economy model of Germany. An approximation of the residual load duration curve is implemented. The approximating function endogenously changes depending on the penetration and mix of variable renewable power. The approach can thus …
