==Objective== | |||
# Time to make some beads! | |||
#* Over the next few weeks we plan to refine this process and discover the most efficient synthesis of these beads. | |||
==Description== | |||
# Begin the Synthesis | |||
## Measure out 0.0550g of Clay and 0.5000g PVA and place in a scintillating vial | |||
# Dissolve the Solid | |||
## Figuring out how much 1M HCl is necessary to completely dissolve the PVA and Clay | |||
##* we want the minimum amount of acid but still dissolve in a timely fashion | |||
##* we determined that we need at least 6mL of HCl and heat | |||
# attempt at beads | |||
## using a Pasteur pipette, drop the PVA-clay into solution | |||
== | ==Data== | ||
<u>Solution Number</u> | |||
# 0.0550g Clay + 0.5000g PVA | |||
# 0.0554g Clay + 0.4989g PVA | |||
<u>Acetone Trial</u> | |||
* PVA-Clay was not strong enough to hold a sphere but rather made string/fibers. This can be weaved into a sort of bead but this cannot be measured | |||
<u>Hexane Trial #1</u> | |||
* HCl is immiscible in Hexane, spherical constitution of beads was overall maintained. Upon adding to Glutaraldehyde, the beads did not stay together. | |||
* Used 250μL Gluteraldehyde in 10mL Hexane | |||
[[Image:20141029_095539-1.jpg|center|478x395px|Initial creation of beads in Hexane.]] | |||
<u>Hexane Trial #2</u> | |||
* This time the Glutaraldehyde was rapidly stirred and the PVA-Clay solution was slowly dropped in. Bead formation was observed while stirring, however the beads were not given enough time to finish cross linking and stuck together. | |||
* Used 100μL Glutaraldehyde in 10mL Hexane | |||
<u>Hexane Trial #3</u> | |||
* Bigger container and more time in between drops in order to allow more time to cross linking. | |||
* 200μL Glutaraldehyde in 150mL Hexane | |||
<u>Hexane Trial #4</u> | |||
* | * Using a blender this time in attempt to make an emulsion. | ||
