OBJECTIVES

  • Begin fluorescence detection through pressure testing analysis of microsphere samples (new modifications & better results)
  • Continue to run DSC sample analysis on microsphere samples previously prepared on 3/29/13
  • Continue to remove excess oil from microsphere samples prepared on 03/29/13
  • Wash microspheres prepared on 03/29/13 with hexanes
  • Dry microsphere samples rinsed with hexanes in preparation for DSC and X-ray
  • Make films containing both clay and PVOH variations to run X-ray analysis
