* Perform pressure testing of microspheres. | |||
* Run X-ray diffraction on a plain safflower oil sample, a plain PVA MW 130 sample, and a PVA 146 microsphere sample that ended up becoming a hydrogel. | |||
* Finish running DSC on a Rhodamine 6G sample(this was unable to be run last time due to lack of gas). | |||

==Pressure Testing== | |||
*The general protocol for pressure testing described on [[User:Moira_M._Esson/Notebook/CHEM-581/2013/04/17|2013/04/17]] was followed. | |||

* It appears as if these microspheres exhibit some sheer pressure response due to the presence of a slight R6G peak. | |||
==X-ray== | |||
General Protocol: | |||
# Use a Kimwipe and acetone to thoroughly clean the low background sample holder | |||
# Insert Sample into the low background holder. Note: Must make sure that the sample is completely flat and that the particle sample size is very small. If the sample is too large, use a mortar and pestle to completely grind the sample | |||
# Turn on the chiller | |||
# Turn on Miniflex II. This is the white button on the machine | |||
# Turn on X-ray. The machine will be on when the red lights on the button labeled x-ray light up | |||
# Using a Geiger counter, test the radiation from the machine | |||
# Set sample in sample holder and record sample holder number | |||
# Close the door to the x-ray | |||
# Open software on computer | |||
