==Today's Objective== | |||
*Begin a gel synthesis reaction, removing sodium sulfide while holding all other conditions constant. | |||
==Protocol (Sample: JCS 13)== | |||
# 5 mL of 15 mg/mL BSA were prepared (0.0759 g in 5mL of millipore water) | |||
# 50 mL of 5mM Mercury(II)Nitrate were prepared (.1056 g of dihydrate in 50mL of millipore water) | |||
## 5 mL of this solution were added to the 5mL BSA solution in a round-bottom flask | |||
# TWO drops of 1 M NaOH was added to the stirring solution. Test with a pH strip indicated a pH of 9 | |||
# This began at 1:40 pm. As of right now, the plan is to add 4 ml of water tomorrow after stirring for 24 hrs. | |||
==Next Steps== | |||
After adding the water and stirring for an additional 15 minutes, the solution will be dried on the rotovap (utilizing a water bath of approximately 40°C). | |||
The dried residue will be rehydrated to attempt gel-formation. Any resulting structures will be analyzed via DSC and pXRD. | |||
Samples for DSC and pXRD will be removed and dried using membrane filtration. | |||

Today's Objective
Protocol (Sample: JCS 13)
Next StepsAfter adding the water and stirring for an additional 15 minutes, the solution will be dried on the rotovap (utilizing a water bath of approximately 40°C). The dried residue will be rehydrated to attempt gel-formation. Any resulting structures will be analyzed via DSC and pXRD. Samples for DSC and pXRD will be removed and dried using membrane filtration. |
