ItemRecycling Electronic Waste: A 21 st Century Challenge(2018) Akinniyi, Akinwande; Phetsopha, Renee; Salazar, GustavoElectronic waste (E-Waste) can be defined as waste material from electric appliances. Currently, a large quantity of E-Waste ends up in landfills, where it can have adverse effects on the environment. Furthermore, E-Waste management is rapidly becoming a global issue due to the difficulty of recycling the key components for reuse.

ItemTWU Chemistry and Biochemistry Recognized Nationally for Innovative, Socially Responsible Program(2019) Maguire, Cynthia; Mirsaleh-Kohan, Nasrin; Sheardy, Richard DeanTWU’s Department of Chemistry and Biochemistry has twice received national recognition in 2018 for innovative and engaging teaching. The Association of American Colleges & Universities (AACU) recognized TWU as being a model for how to make civic learning and democratic engagement an expectation for all students who major in chemistry or biochemistry. The National Center for Science and Civic Engagement (NCSCE) also recognized TWU for making extraordinary contributions to citizen science education after more than a decade of using civic engagement to successfully draw students’ interest in courses for non-science majors. The department hosts the SENCER Center for Innovation‒Southwest (SCI-SW), part of a national program founded by NCSCE. SCI-SW focuses on three areas of expertise: Environmental Sustainability, Science Teacher Preparation, and Undergraduate Research. ItemPromoting Science Through Wizardry(2019) Maguire, CynthiaAn unexpected opportunity come salong when we least expect it, and that is how I came to travel to Middle Earth (NewZealand) as a wizard apprentice in fall 2016. Along the way, I learned a totally new and unique way of relating science information to children, thereby increasing their interest in science. My poster is a description of my journey as I truly became the Mistress of Potions (MP for short). Since returning to Texas, I am seeking opportunities to visit schools for kids of all ages in order to demonstrate the power—and fun—of science! Wizarding performances are provided free of charge, but when overnight travel is needed the community is asked to provide local meals and a bed in someone’s home. This provides the opportunity to strengthen bonds with the people I meet while reducing the cost of providing this unique performance to schools. Performing as the Mistress of Potions, I hope to be a role model for young women in science and an ambassador for TWU. ItemBiliteracy Development for 21st Century Learners(2019) Guajardo, Esteffanee; Pérez, Melina; Stewart, Mary Amanda, 1979-The number of bilingual students in U.S. public schools grew 64% from 1995 to 2010. •More schools are offering dual language, ESL, and world language classes. •Texas has adopted the Seal of Biliteracy for high school diplomas. The Certificate of Biliteracy is a post baccalaureate certification for all educators: ESL teachers, dual language teachers, elementary teachers, middle and high school teachers, world language teachers, literacy coaches, administrators, and any educator invested in bilingual students’ academic achievement. ItemInteraction between γC87 and γR242 residues participates in energy coupling between catalysis and proton translocation in Escherichia coli ATP synthase(2019) Li, Yunxiang; Ma, Xinyou; Weber, JoachimFunctioning as a nanomotor, ATP synthase plays a vital role in the cellular energy metabolism. Interactions at the rotor and stator interface are critical to the energy transmission in ATP synthase. From mutational studies, we found that the γC87K mutation impairs energy coupling between proton translocation and nucleotide synthesis/hydrolysis. An additional glutamine mutation at γR242 (γR242Q) can restore efficient energy coupling to the γC87K mutant. Arrhenius plots and molecular dynamics simulations suggest that an extra hydrogen bond could form between the side chains of γC87K and βTPE381 in the γC87K mutant, thus impeding the free rotation of the rotor complex. In the enzyme with γC87K/γR242Q double mutations, the polar moiety of γR242Q side chain can form a hydrogen bond with γC87K, so that the amine group in the side chain of γC87K will not hydrogen-bond with βE381. As a conclusion, the intra-subunit interaction between positions γC87 and γR242 modulates the energy transmission in ATP synthase. This study should provide more information of residue interactions at the rotor and stator interface in order to further elucidate the energetic mechanism of ATP synthase.
