Understanding the Structure and Dynamics of Monolayer thick films of n-alkanes Requesting applications from science or engineering faculty members at institutions serving students underrepresented in science, engineering, mathematics and technology to work on the following projects at Oak Ridge National Laboratory (ORNL). Project Description Understanding the structure and dynamics of monolayer thick films of n-alkanes adsorbed on the surface of a prototype metal oxide surface. This is part of an ongoing project that uses nanocubes of MgO synthesized as part of the BES Materials Chemistry activities in the Chemical Sciences Division. Faculty and students will participate in the thermodynamic characterization of the adsorption properties of hydrogen bearing small molecule using a high-resolution volumetric isotherm apparatus in preparation for an inelastic neutron scattering (INS) experiment at the Institute Laue Langevin in Grenoble or an appropriate neutron scattering facility in the US. The participants will then be involved in the execution of an INS experiment to determine the onset of mobility in these adsorbed films by using changes in the dynamical response of the film as a function of temperature. In addition to the basic research nature of this investigation, these activities have as a goal the preparation of a new generation of users for the Spallation Neutron Source by illustrating first hand, the power of INS as an extremely valuable tool for the characterization of the microscopic structure and dynamics of condensed matter. Laboratory Contact: J. Z. Larese jzl@utk.edu or laresejz@ornl.gov Applicants’ Responsibilities and Relationship to Project Applicants will receive support under the Department of Energy Faculty Student Team Research Program (FaST) to work collaboratively with the project research team at the Laboratory for up to 10 weeks during the summer of 2008. The exact appointment period in the time frame of June to August will be scheduled by mutual agreement between the host divisions at Oak Ridge National Laboratory and the successful applicant. Faculty will be expected to identify students from their campuses to participate in the FaST program. The faculty member will provide some mentorship to students during the summer research activities. The faculty and students must participate as a group and serve their appointments concurrently. It is expected that the faculty member and the students become an integral part of the research team working on this project and that opportunities for continued collaboration may be identified. Qualifications of Ideal Candidate Faculty and students in physical chemistry and material science are preferred. Support and Financial Commitments The successful candidate will receive a stipend based on the academic salary, travel expenses to and from the Laboratory, and a housing allowance. Students recommended by the faculty member for participation in the program will receive a stipend of $400/week for each week at the Laboratory, plus a housing allowance, and reimbursement for transportation expenses to and from the ORNL. Funds are provided for this program from the US Department of Energy, Office of Science in partnership with the National Science Foundation, from ORNL, and from other sources.
