  1. CAREER: Chemically Modified Ternary Chalcogenide MaterialsBenjamin R. Martin, Texas State University - San Marcos, DMR 0748140 Alkali metal chemistry in electrochemically active structures is of interest for energy storage applications. The movement of alkali metals through layered structures may be optimized by modifying the activity of the metal or by modifying the structure through chemical transformations. Based on our previous work with Li/Na/Co/S phases we have begun to explore the ability of this material to be exfoliated (delaminated to form a highly dispersed nanoparticle material) in order to increase the surface area. Preliminary results indicate that a general method for solvent-assisted exfoliation of partially oxidized chalcogenide phases such as Na0.5LiCoS2 is successful. a b TEM image of unmodified structure TEM image of modified structure LiNaCoS2

  2. CAREER: Chemically Modified Ternary Chalcogenide MaterialsBenjamin R. Martin, Texas State University - San Marcos, DMR 0748140 Family Science Night (FSN) was developed to allow a venue for parents and children to explore science projects together in a guided environment. A trained group of students and professors travel to school campuses and host a two hour FSN is currently in its third year of development. Three full experiments have been developed, including the addition of the new experiment “Everything in Balance,” which was developed and implemented in Spring 2010. In this experiment, children build their own balance and use it to measure densities of liquids and solids. Children practice filtration using synthesized iron oxide Children paint a wall mural for the school using their synthesized pigments
