crosslink PVOH/glutaraldehyde and PVOH/PDMS/glutaraldehyde
films, make a 1 g PVOH/glutaraldehyde film, make additional
standards, and finish clay-CuSO4 exchange (from 9/26).
Crosslinking Glutaraldehyde Films    1. Allow the PVOH film
containing glutaraldehyde to dry completely.   5. Place film in
solution for one hour.   7. Heat HCl solution to 70°C   9. Place
film into HCl solution for 30 minutes.   13. Rinse film with
deionized water and place in a beaker with distilled water until
it is used.  Making a 1 g PVOH/glutaraldehyde film    1. 1 g of
PVOH was weighted out and dissolved in 6 mL of water in a small
beaker with a stir bar.   2. The beaker was placed on a hotplate
and was heated to allow the PVOH to dissolve into the water.
3. 1 mL of glutaraldehyde was added to the PVOH.   4. The
solution was stirred under the
