D4.00001: IPLWC7 Conference Regina Barrera, Tia Hall, Stephanie Ingle, Christine Miller, Dwain Desbien, Thomas O'Kuma The Introductory Physics Laboratory Writing Conference is a series of 3-day intensive workshops at which teams of two-year college and high school physics faculty write introductory physics laboratory activities. The IPLWC7 conference concentrated on biology related activities for the introductory physics laboratory. This poster will illustrate some of the developed biology related lab activities.

D4.00002: Interactive Computational Physics Zakary Noel Vpython is a graphic computer program that is useful for easily creating representations of physical situations that cannot always be replicated in conventional labs. My goal is to present a number of programs that will further aid in making Vpython an interactive, easily useable tool for both those with and without prior programming knowledge. I hope to include projects developed in and out of class time, and display individual components of programs which can be integrated into other simulations. [Preview Abstract] |

D4.00004: ATE Workshops for Physics Faculty Thomas O'Kuma, Dwain Desbien The ATE Workshop for Physics Faculty project is into its fifth year and has finished its 22nd workshop/conference. In this poster, we will display information about the project, information about these workshops/conferences, and information about future workshops/conferences. Information concerning development of laboratory activities will also be displayed. [Preview Abstract] |

D4.00005: Bremsstrahlung produced by low-energy (keV) electrons incident on thick Ag Sean Czarnecki, Scott Williams Recently, there has been some controversy concerning whether polarizational bremsstrahlung (sometimes referred to as ``atomic bremsstrahlung'') contributes to the total bremsstrahlung spectrum in experiments involving electrons incident on solid-film targets. Here, the bremsstrahlung probability density predictions of the widely-used Monte Carlo code, PENELOPE, are compared to the results of experiments involving 17.5-keV and 20-keV electrons incident on a thick Ag target. Comparisons of the results of our experiments to the predictions of the PENELOPE code, which is based on ordinary bremsstrahlung alone, suggest that there were no significant polarizational bremsstrahlung contributions to the total bremsstrahlung spectra in our experiments.

D4.00006: Reuven Ramaty High Energy Solar Spectroscope Imager (Rhessi) Results Analyzed In Seasonal Quadrants Carolynn Conley The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) Small Explorer Mission was launched on Feb. 5, 2002. RHESSI was designed to collect solar flare and coronal mass ejection data. In addition, for over a decade, RHESSI has also observed lightening generated energetic eruptive events. These were named Terrestrial Gamma Ray Flashes (TGFs) and have been observed since 2002. Data collected shows a distribution of TGFs randomly spread in the latitudes and longitudes that satellites observed. This study investigates the seasonal variation in the RHESSI data. RHESSI TGF data is available since the start of data collection in 2002 to 2012. Observation of this data suggests that a distribution of activity may be observed. The TGF weekly rates are compared at the four seasons, spring, summer, fall, and winter, in the northern and southern hemispheres. The TGF rate may be a function of the relative position of the earth to the sun and relative to the earth's geographic and magnetic poles. The spectra of original interest to RHESSI and other investigations produced by the heliosphere environment are being distinguished from TGFs in the Earth's atmosphere. [Preview Abstract] |

D4.00008: Stability Analysis of Catalytic Compounds Using Computational Simulations Richard Kyung, Kwangjin An, Gabor A. Somorjai The ultimate goal of the research on the energy is to actualize green energy and increase its efficiency, achieving better selectivity and molecular stability of the desired product. Metal nanoparticles and oxide supports can increase catalytic selectivity to obtain desirable products. In this paper, the chemical catalytic efficiency and physical activities of proposed metal oxide compounds are modeled and analyzed using computational simulations. The compounds' mechanical repulsive forces, electron structures, and bond strengths are explained. In order to model the electron properties of the compounds, the computational and numerical DFT methods are used. To check the mechanical stability and convergence of the solutions,~energy(kcal/mol) versus computational steps(N) curves for each metal compounds are presented.~Also, the theoretical structure of each feasible catalytic Platinum(Pt) compound has been studied in this project. Based on the predicted physical stability of each molecule, the compound that can be used most efficiently to catalyze the reaction for the green energy can be determined. [Preview Abstract] |

D4.00009: Analysis of Nitrogen Doped Graphene via Scanning Electron Microscope and Raman Spectroscopy Bradley Hines Analysis of Nitrogen Doped Graphene via Scanning Electron Microscope and Raman Spectroscopy HUNTER HINES, Department of Physics and Astronomy, Stephen F Austin State University- Nitrogen Doped Graphene is an alteration of graphene via the insertion of nitrogen atoms into the lattice of the carbon atoms. The purpose of this study was to characterize the structural and electronic properties of nitrogen doped graphene in comparison to similar properties of undoped graphene. This was done by analyzing a Nitrogen doped Graphene powder acquired from ACS using a Perkin Elmer Raman Station 400 fitted with a 785 nm laser at 50 mW and a JEOL-JSM-6100 scanning electron microscope (SEM).
