Brandon Lee's "STEAM" presentation of NSF & UVA CDE STEM Nanotechnology research


Published on

This was summer research that was completed through the National Science Foundation (NSF) grant provided to the Center of Diversity in Engineering (CDE) at the University of Virginia (UVA). The Research Experience for Teacher's (RET) placed me as a visiting research assistant, in the Civil & Environmental Engineering department's Virginia Environmentally Sustainable Technologies (VEST) Lab at UVA. I joined a collaborative effort to assist ongoing research under Dr. Andres Claren, professor and student, Shibo Wang.

I was able to develop practical lessons for students to implement current research in the field of Science Technology Engineering Arts and Math (STEAM). Creating a wikispace that will allow for ongoing collaboration, including resources and examples of class lessons.

Brandon Lee's "STEAM" presentation of NSF & UVA CDE STEM Nanotechnology research

  1. 1. Evaluating CO 2 leakage from sequestration sites using column studies Brandon C. Lee Shibo Wang, Brian Weaver, and Andres Clarens Department of Civil and Environmental Engineering- VEST LAB About this template Global climate change mitigation strategies, like G eological Carbon Sequestration (GCS) , are promising. The process of storing carbon dioxide underground, from fossil fuel emissions, is accomplished by isolating the CO 2 molecule and compressing it to transport by pipeline to an injection site to be stored permanently. Sequestration substrates include: depleted oil and gas reservoirs, shale formations, un-mineable coal seams, and underground saline formations. Saline formations have the highest availability and potential for high emissions yield. Therefore, underground formations provide a high accessibility rate, increasing the overall potential of GCS technology globally. Research and development of GCS must continue to determine the most effective methods of CO2 sequestering in geologic reservoirs to mitigate global warming.; in addition to assuring long-term effectiveness Related Research Methods Text Sizes Direct Research Contribution I worked to analyze prior experiments and identify the most efficient methods to progress . I researched experiment methods for measurement systems and instruments for the column. I collaborated with the graduate students in the VEST lab to design a new column to model a system that would assist with visual observation of the CO2 buoyancy forces. I helped with the ordering and assemblage of parts. Finally, I assisted with the educational framework for the UVA energy Consortium in order to promote energy research an implement it into the classroom. Progress of Research We made I significant advancements. I was asked to complete the 50cm column, in order to make preliminary observations of CO2 transport. This includes the new method and design of our electrical resistivity measurement system. The procedure will hopefully be replicated for the 6m column experiment, which is still being adapted, to be housed in the VEST Lab. We have made steps to alleviate measurement methods with the 1m column; and have pulled research to investigate the next steps. Therefore, trials will continue through late summer as well as early fall of 2011 to prepare. Module Introduction Global Warming is the heating of the Earth caused by an increase in greenhouse gasses (ghg). Of the many byproducts created by human activity, CO 2 is the most abundant and it warrants mitigation to assuage the GHGs . Students must understand technological innovation for mitigation efficiency in Carbon Capture and Storage (CCS) In order to understand where the permanent storage of carbon dioxide takes place in geological carbon sequestration (GCS), the students must understand layers of the Earth, air quality and the water cycle,. They must know the technological model and process. The lesson focuses on understanding key terms. Students will watch a short film about the climate change, groundwater, aquifers and geological carbon sequestration, and utilize GIS systems to identify GCS sites. They will research in-depth information from international, national and state resources that I have provided a WIKI.-space page. This wiki-space will serve the class for science technology engineering and math (STEM) lessons designed to hit the various topics. This will provide the teacher and students with perspectives to teach and comprehend the subject matter, like that of a geoenvironmental engineer or chemist. International, National and State Standards addressed Materials For Lesson Module EDUCATIONAL CONNECTIONS TO RESEARCH ACKNOWLEDGEMENTS CONTACT INFORMATION The research objectives are structured as a direct result of global climate change mitigation leadership initiatives. From the international agencies to our national president, educational standards of learning are developed analogous to the governments organizational dissemination process and hierarchal frameworks. The research practices and dissemination process will be a model framework to achieve engaging class lessons. The Students will study global climate change mitigation through Geological carbon sequestration (GCS) dissemination process. Science Technology Engineering and Math (STEM ) initiatives are the analogous governmental framework to GCS. Both initiatives can be encompassed in the basic standards in Career and Technology Education classes (CTE). Each student will engage in interactive games and activities that allow time for research of terminology., utilizing the design process and collaborative workplace skills. Greetings to ALL who took part in the research experience this summer. Special thanks goes to the National Science Foundation and Ms. Carolyn Vallas and Juliet Trail at University of Virginia, Center for Diversity in Engineering. I extend my gratitude to Dr. Andres Clarens and the Vest Lab research team; particularly PhD candidates Shibo Wang and Brian Weaver, for volunteering their time, space, and energy. In addition to allowing me to join their team and participate in their projects. Thanks to undergraduates Ian & Erika for guiding my helping model research practices. I would also like to thank In Dr. Andres Clarens’ Virginia Environmentally Sustainable Technologies (VEST) lab at UVA’s School of Civil and Environmental Engineering; collaborative research is underway with Princeton University, as well as Brookhaven National Lab. The team is investigating GCS methods for CO2 transport, trapping, and leakage in underground carbon sequestration sites globally. Monitoring buoyancy factors, we utilize authentic tests, which cannot be accomplished due to depths at the large-scale. Replicating environmental conditions in the laboratory, variables such as pressure, temperature, and aquifer materials are manipulated to simulate geological reservoir formations. We must establish a working procedure for a larger-scale 6meter column, thus a smaller 1m column followed by a 50cm column were constructed. The 1m column was erected, to reach the conditions of 800 m to 3km under the Earth s surface with temperatures spanning 25°C to 50°C and geological pressures exceeding 1 bar and injection pressures as great as 3,000psi. The experiments require efficient measuring instruments and methods; Gas Chromatography (GC) and electrical resistivity were investigated .
