Day 1: I learned safety procedures in the chemistry lab, the solvated metal atom dispersion (SMAD) technique, and how to keep a scientific notebook.
Day 2: I learned how to set up reflux for an as prepared SMAD product, and how to properly clean the glassware.
Day 3: I researched different ligands. I also learned about UV absorption spectroscopy, how to use Ocean Optics Spectra Suite, and a spectrometer.
Day 4: I learned how to use the Transmission Electron Microscope to view poydispersed and monodispered sample of gold nanoparticles, and analysed data to prepare graphs.
Day 5: Meetings and presentations with NIRT group, Dr. Klabunde’s team, and REU.
Day 6: I learned technique for distilling and degassing acetone and how to properly heat crucible so there will be no oxygen in the crucible.
Day 7: I learned safety when filling liquid nitrogen tank and ran SMAD reaction for a different concentration.

Day 10: Meetings. Continued to compile data and learned about fluorescence of CdSe.
Day 11: New SMAD reaction and continued to compile data.
Day 12: Since the vacuum was not functioning properly, we disassembled and cleaned the vacuum line.
Day 13: Ran another SMAD reaction varying the ligant.
Day 14: Refluxed two as prepared SMAD products and worked on florescence and UV of CdSe.
Day 15: Meetings and presentations with NIRT group, Dr. Klabunde’s team, and REU.

Day 25: Graphed the water soluble gold UV-VIS yielding good results
Began Inverse micelle procedure
Day 26: Meetings and presentations with NIRT group, Dr. Klabunde’s team, and REU.
Day 27: Took UV-VIS of first micelle sample and were no gold nanoparticles present
Heated crucible for the next day’s SMAD reaction
Day 28: Refluxed the 1:15 as prepared SMAD product and did not reflux properly.
Day 29: Decanted and vacuum dried the micelle samples
Refluxed the 1:30 micelle sample in toluene to see the UV-VIS sample
Day 30: Refluxed 1:15 and 1:60 and took the UV-VIS and got good results
Day 31: NIRT meeting and REU group meetings
