No water supply or nitrogen was connected for this experiment. The temperature is not high enough to have a reflux reaction. | No water supply or nitrogen was connected for this experiment. The temperature is not high enough to have a reflux reaction. | ||
Dr. Hartings asked to collect through precipitation. When I worked on the QDs [[User:Matt Hartings/Notebook/AU Biomaterials Design Lab/2014/02/06|last year]], about 200mL of chilled ethanol was added to the mixture of about 70mL. The mixture I have now is around 12mL so I only added 17ml of ethanol to 6mL of the solutions (one prepared from HgCl2 and the other from HgNO3). I'm not quiet certain if it is the right procedure or not, so I only used half of the solutions. The door for the centrifuge room was looked anyway. I will check in the morning with Dr. Hartings. | Dr. Hartings asked to collect through precipitation.

Dr. Hartings also asked to start a "hot injection" synthesis. I'm not quiet familiar with the process either. I will wait till tomorrow to ask Dr. Hartings. | Dr. Hartings also asked to start a "hot injection" synthesis. I'm not quiet familiar with the process either.

ProcedureThe same procedure of synthesis was used. The variac this time was set on 17/100 to match a temperature around 30C. I added only 25microliter of NaOH this time, so the pH was set around 9 as it is supposed to be according to the paper I attached earlier last week. No water supply or nitrogen was connected for this experiment. The temperature is not high enough to have a reflux reaction. Dr. Hartings asked to collect through precipitation. When I worked on the QDs last year, about 200mL of chilled ethanol was added to the mixture of about 70mL. The mixture I have now is around 12mL so I only added 17ml of ethanol to 6mL of the solutions (one prepared from HgCl2 and the other from HgNO3). I'm not quiet certain if it is the right procedure or not, so I only used half of the solutions. I did not used chilled ethanol this time. I used ethanol on the shelf. The door for the centrifuge room was looked anyway. I will check in the morning with Dr. Hartings. Dr. Hartings also asked to start a "hot injection" synthesis. I'm not quiet familiar with the process either. I will wait till tomorrow to ask Dr. Hartings. |
