  • Centrifugal sieving for the size separation of lunar regolith in microgravity 

    Contributor:Martinez, Myles; Fruit, John; Dreyer, Christopher; Walton, Otis; Riedel, Ned
    For any microgravity environment traditional sieving methods used on earth can fail or be less effective for smaller size particles. Previously a device was designed and built that uses centrifugal force created by a ...
  • Gas hydrate adhesion to mineral surfaces 

    Contributor:Leith, Will; Aman, Zachary M.; Sum, Amadeu K.; Koh, Carolyn A.
    Hydrates are crystalline inclusion compounds, where water forms cages that encage 'guest molecules' (typically hydrocarbons). The amount of energy stored in gas hydrates is estimated to be twice that of traditional fossil ...
  • Raman spectroscopy of silicon quantum dots 

    Contributor:Rachel, Kurchin; Kendrick, Chito; Collins, Reuben; Furtak, Thomas
    Silicon quantum dots are synthesized and studied extensively by REMRSEC, but they have not thus far had a fast and reliable way to characterize them. In this work, Raman spectroscopy is employed to study dots in varying ...
  • Using AFM to find evidence of conformal monolayers 

    Contributor:Meinig, Erich; Brenner, Thomas; Chen, Gang; Collins, Reuben; Furtak, Thomas
    Atomic force microscopy (AFM) is one of the tools used to infer whether a conformal monolayer of the surface treatment exists. AFM roughness measurements can be used to detect changes in height before and after surface ...
  • Novel bimetallic catalysts for use in anion exchange membrane fuel cells 

    Contributor:Sather, Nicholas A.; Ham, James M.; Herring, Andrew M.; Greenlee, Lauren F.
    Widespread implementation of current fuel cell technology is inhibited by the scarcity and price of the catalysts on both the anode and cathode. However, recent research suggests that Alkaline Anion Exchange Membrane Fuel ...
  • Renewable energy and climate change education 

    Contributor:Kawaguchi, Kelsey; Howell, Cynthia; Munakata-Marr, Junko; Mitcham, Carl
    To identify barriers to incorporating climate change (CC) education into high school and community college courses, 24 national educators were interviewed. During each 30-minute recording, instructors described experiences ...
  • Spatial frequency modulation for imaging (SPIFI) in optical and mid-IR wavelength systems 

    Contributor:Johnson, Nicole; Corchado, Jaime; Squier, Jeff; Toberer, Eric
    This work aims to use a single element detector for 2D imaging. The work uses frequency encoding to eliminate the need to scan in the direction of line focus and it uses a Fourier transform detector signal to recover ...
  • Centrifugal sieve segregation in micro gravity 

    Contributor:Fruit, John Terrell; Martinez, Myles Kristian Alexander; Dreyer, Christopher; Walton, Otis
    Sieving in space could be crucial to applications such as yielding smaller material for construction and extraction. Thus, improvements were implemented to a centrifugal sieve which included: Labview operating VI for motor ...
  • Benzoic acid surface functionalization of conduction band engineered Zn1-xMgxO layers for enhanced organic/inorganic photovoltaics 

    Contributor:Flores, Tom; Brenner, Thomas; Chen, Gang; Furtak, Thomas; Collins, Reuben
