outreach activities

Showing the students a schematic of a diamond anvil cell and sample area.•  The UT Austin outreach was conducted Thursday June 23, 2011 and Tuesday July 5, 2011 in collaboration with Mary Miller and her intern Sara Jeanes of the UTeach program at the University of Texas- Austin. The UTeach program focuses on preparing undergraduates at UT-Austin to teach secondary science courses such as chemistry, biology, geology, and computer science. UTeach hosts a three-week summer camp every year to expose students to these subject areas, as well as to keep them engaged during the off-season. The students that came to the mineral physics lab were participants in math, chemistry, or geology focused camps. Many students were underrepresented minorities, and some required translation. The students ranged from 6th to 7th grade and were from various schools in Austin including the Kealing Magnet Program. All students underwent a pre-lesson before coming to UT, subjects were pressure, crystal structure, or diamonds.

The theme of the mineral physics lab tour was, “diamond anvil cell and high-pressure research” One group of 19 students, six groups of 12 students, and one group of about 10 teachers, each explored the lab, passed around a diamond anvil cell (DAC), observed real and synthetic diamonds, witnessed ruby fluorescence, and learned about the relationship between pressure and area and how it is exploited via the DAC. The students learned how Raman spectroscopy and the DAC can be used to study properties of planetary materials at extreme conditions in the Earth’s deep interior as well as projects related to Energy Frontier Research under Extreme Environments (EFree) of the Department of Energy. We learned about how extreme environments can change material properties and how novel materials can be discovered under extreme environments in a DAC. Jung-Fu Lin appointed Andrea Wheat, an undergraduate researcher, to help out with the presentations in the lab. [photo: Andrea show the students a schematic of a diamond anvil cell and sample area.]

Lastly, the teachers and students were shown 200 diamonds and given broken diamonds as rewards for asking good questions or for answering questions.

•  Roald Hoffmann of Cornell University was interviewed in Feb. 2011 for a community access station in Ithaca. He spoke of the Hoffmann-Ashcroft group's work on matter under high pressure.

•   Team members of the Center for Frontiers of Subsurface Energy Security (CFCES) Center of the Energy Frontier Research Centers (EFRC) from University of Texas at Austin and Sandia National Laboratory visited Jung-Fu Lin’s Mineral Physics Laboratory in Sept. 2010. During the visit, Afu Lin explained how his group uses high-pressure diamond anvil cells to investigate material properties in extreme environments relevant to EFree missions. Dr. Lin also discussed potential collaboration projects with the CFCES members using the Mineral Physics Lab’s facilities, enhancing scientific collaborations between EFRC centers.

Roald Hoffmann gave a lecture at Northwestern University on “The Chemical Intuition at Work in Very Tight Places”. Also in October 2010, he talked about his organization of the Cornelia Street Café cabaret “Entertaining Science,” at a CUNY conference on Science and the Performing Arts. R. Hoffmann lectured at the University of California, Davis, in May 2010, in part on high pressure (EFree supported) work.

EFree Partners participated as mentors in Carnegie's summer scholars program at the Geophysical Laboratory and the Department of Terrestrial Magnetism. Michael Wong and Alex Goncharov used diamond anvil cells to study the thermal conductivity of argon. Donald Plattner and Madury Somayazulu investigated the formation of clathrates in a H2O-CO2 mixture and to study the chemical interactions between water and CO2 at supercritical conditions.  Amanda Lindoo with guidance from Stephen Gramsch, Atsushi Kyono, a visiting investigator, addressed the possible role of pressure in the exsolution process, with a focus on the humite group. For more information on the program, please see http://people.gl.ciw.edu/summerscholars/about.html.

Naveen Dharmagunawardhane, a Missouri State graduate student in materials science, and Joseph Demster, an undergraduate student in physics, participated in x-ray experiments at the Advanced Photon Source synchrotron facility located in Argonne National Laboratory near Chicago, Ill. The work was done under the supervision of Dr. Robert Mayanovic, professor of physics, astronomy and materials science. Their research involved investigations of novel materials needed to meet the challenges posed by future energy demands. The Missouri State University researchers are participants in the Center for Energy Frontier Research in Extreme Environments (EFREE), which is a national center funded by the Department of Energy.

Demster, a physics major who anticipates graduating this spring, accompanied Dr. Mayanovic to Argonne in August. In his first semester at Missouri State, Dharmagunawardhane is an international student from Sri Lanka and a graduate assistant. He went with Dr. Mayanovic in October.['Materials science students shine", Mar 16th, 2010 by Kenneth McCrory, APS News webpage (Source: http://www.aps.anl.gov/News/APS_News/Content/APS_NEWS_20100317.php)]
