*Note: At first put the solution in an Erlenmyer flask, but needed to add 20mL H<sub>2</sub>SO<sub>4</sub> so dissolved the Na<sub>2</sub>SO<sub>4</sub> in 1000mL deionized H<sub>2</sub>O using a magnetic stir bar and a stir plate. Then transferred into a 2000mL solution bottle with cap. | |||

Objectives
Fixant Solution preparation
Film preparation
The films were prepared following the General Protocol described on2012/09/12
*PDMS density=0.97g/mL 5%(1.00gPVOH)=0.95g+0.05gPDMS 0.05g(1mL/0.97g)=0.0515mL PDMS must be added to create 5% replaced PDMS film
The film was prepared following the General Protocol described on2012/08/29
SO42- DilutionsGeneral Protocol for Dilutions:
1ppm: M1V1=M2V2 (20ppm CuSO4stock)(V1)=(1ppm)(50mL) V1=2.5mL= volume of stock needed to prepare
2ppm: V1=(2ppm)(50mL)/20ppm V1=5mL
5ppm: V1=(5ppm)(50mL)/(20ppm) V1=12.5mL
10ppm: V1=(10ppm)(50mL)/(20ppm V1=25mL
20ppm: V1=(15ppm)(50mL)/(20ppm) V1=37.5mL
X-RayThe General Protocol for X-Ray described on 2012/09/19 was used
Note: This clay was particularly difficult to grind. It is also reddish brown in color DSCDSC ran on 9/14/2012 was analyzed. Glass transition states were calculated using the program
