Objectives

  1. DSC
  2. Fluorescence testing (protocol described last meeting)
  3. Microscopic analysis of N2 prep
  4. Centrifuge N2 prepared samples for analysis tomorrow


Microscope

  • Please refer to Puja Mody's notebook for microscope data


Fluorescence

  • The general protocol for magnetic testing described on 04/02/2014 was followed.

Figure 1. Intensity of R6G from hydrogels after application of an external magnetic stimuli Magnetic Testing Day .png
Figure 2. R6G not absorbed by the hydrogels Concentration Rhodamine 6G not absorbed by magnetite hydrogels .png

 As the intensities were so low for all of the hydrogels, this test will be repeated using a higher concentration of R6G and a modified method.


DSC

General Protocol for DSC samples:

  1. Equilibrate at 0°C
  2. Isothermal for 2 minutes
  3. Ramp 10°C/min to 240°C
  4. Isothermal for 2 min
  5. Ramp 100°C/min to -40°C
  6. Repeat segment 2, 1 time


  • Only one sample was fully analyzed due to lack of carrier gas. All samples will be re-run
