Presentation Transcript

  1. By Sydney Waynick, Steven Prascius, and Hunter Montrose The Formation of Silver Crystals in a Microgravity Environment Macomb Mathematics Science Technology Center – Warren Consolidated Schools

  2. Macomb Mathematics Science Technology Center is Spearheading Warren Consolidated School's Participation in SSEP

  3. Properties of Silver Crystals • Metal Organic Framework • Store natural gases • Cubic nature • Cubes • Octahedrons • Dodecahedrons • Tetra hexahedron

  4. Cubic Varieties

  5. Applications • Gas storage • Vehicles • Space flight • Humans are able to go further than ever before! • Carbon capture • Separating and purifying gases

  6. Crystal Storage • Gas molecules can be stored at a higher density on the surfaces of MOFs than in conventional tanks • Three-dimensional metal-organic framework with pore sizes in the nanometer range • Greater porosity = greater surface area • Rapid Development

  7. Silver Crystal Formation • Chemical reaction between Ag and Cu • Cu(s) + 2Ag+(aq) → Cu2+(aq) + 2Ag(s) • Coiled Copper wire • Greatest surface area http://2012books.lardbucket.org/books/general-chemistry-principles-patterns-and-applications-v1.0/section_08_08.html

  8. Experiment • Purpose • To determine the effect of microgravity on the formation of Silver Crystals • Hypothesis • We predict that the silver crystals will form the same as they do an earth in an environment with microgravity because the reaction does not depend on gravity. • Neutral buoyancy of water is similar to microgravity

  9. Materials Silver Nitrate 5 mL water 20 cm copper wire

  10. Procedures (Pre-Launch) • Prepare a 0.1 molar solution of Silver Nitrate • Pour the Silver Nitrate solution into the FME tube • Place clamp above the Sliver Nitrate solution on the tube • Place the 20cm long coiled copper wire above the clamp and seal the tube Silver nitrate solution

  11. Data collection • Comparison: • Ground vs. Space sample • Size • Shape • Color

  12. Ground Based Results • Twining • Shape • Size

  13. Ground Based Results • Color • Tarnished / Untarnished
