	<u>Data Collection from DSC</u>		<u>Data Collection from DSC</u>

		+	# Open program TA Universal Analysis
		+	# File → open → DSC → Chem 581 → NLK → open the file you want
		+	# Same as lets you do the same manipulations as what you did to previous
		+	# Click open or whatever it says
		+	# Analyze → integrate peak → linear → pull red line to a spot to the left of the peak and to the right of the peak → right click to accept limits
		+	# Get glass transition → analyze → glass transition → select each side (left and right) → accept limits → glass transition is point with (1)
		+	# File → export pdf → save as pic
		+	# File → export data file → plot signals only → ave it as .txt

-	<u>~~Part 1~~</u>	+	<u>Prepare a Copper Sulfate Solution</u>

	# A solution consisting of 1.25 g CuSO<sub>4</sub> hydrate in 500 mL HPLC grade water was prepared		# A solution consisting of 1.25 g CuSO<sub>4</sub> hydrate in 500 mL HPLC grade water was prepared


		+	<u>Filtering the Na-MT Clay</u>

-	<u>~~Part 2~~</u>	+	# 50% and 100% exchanged Na-MT clay with HdPh<sub>3</sub>P<sup>+</sup> (prepared on 9/12/12) were filtered.

-	~~# 50% and 100% exchanged Na-MT clay with HdPh<sub>3</sub>P<sup>+</sup> (prepared on _______) were filtered.~~

		+	<u>Crosslinking</u>

		+	* Glutaraldehyde films prepared on 9/19 were placed in glutaraledhyde fixant at 70°C for one hour

		+	# Allow the PVOH film containing glutaraldehyde to dry completely.
		+	# Prepare a solution of 100 mL H<sub>2</sub>O, 2 mL concentrated H<sub>2</sub>SO<sub>4</sub>, and 20 g Na<sub>2</sub>SO<sub>4</sub> in a 150 mL beaker. (solution is referred to as glutaraldehyde fixant)
		+	# Place stir bar in beaker and a Buchner funnel top (cap) over the stir bar
		+	# Heat solution to 70°C (temperature on hotplate should be about 160)
		+	# Place film in solution for one hour.
		+	# Prepare 100 mL of a 1% HCl solution in a 150 mL beaker. Place a stir bar and an inverted buchner funnel into beaker.
		+	# Heat HCl solution to 70°C
		+	# Remove film from glutaraldehyde fixant and rinse with distilled water.
		+	# Place film into HCl solution for 30 minutes.
		+	# Prepare 0.2 M sodium bicarbonate solution. (1.68 g in 100 mL)
		+	# After 30 minutes, remove the film from the HCl solution and place into the sodium bicarbonate solution (at room temperature) for about 15 minutes.
		+	# Use tweezers to remove the film from the sodium bicarbonate solution.
		+	# Rinse film with deionized water and dry film on paper towel.

-	~~<u>Part 3</u>~~

-	# ~~Glutaraldehyde films prepared~~ on ~~9/19 were placed~~ in ~~glutaraledhyde fixant at 70°C~~ for one ~~hour~~	+	<u>X-Ray (Including Instructions)</u>
		+
		+	* X-ray was carried out on the 100% and 50% CEC clays and the Na-MT clays
		+	* Password for the computer is rigakua
		+
		+	# Make sure Haskris white box by the door is on
		+	# Remove samples from the door, check radiation levels with the Geiger counter
		+	# Push on button, can either turn X-ray on or put the sample in (order doesn't matter)
		+	# Open standard measurement program
		+	# Click button above number and it will copy the program numbers that you highlight. (Button above print deletes)
		+	# Enter file name (to get this click browse on your number)
		+	# Can add sample name (optional)
		+	# Attach → click big button in center → can make the sample rotate (sample spin, good for heterogeneous samples, don't need to do for powders, usually click none)
		+	# Condition → big button on right (tells whole range, set to not go below 1°) → start θ = 2°, stop θ = 40°, sampling width = 0.1, scan speed = 1 (larger scan speed takes less time, can also do .2 but takes 3 hours) → exit out or this window
		+	# Change sample to your sample number
		+	# Click big button on the left to start doing stuff
		+	# Window that opens might pop up if x-ray is being used for the first time in a while, just click ok if you haven't done anything.
		+
		+	To collect data:
		+
		+	# Click PDXL
		+	# File → open
		+	# Change PDXL file type to all files
		+	# Select .raw file and open
		+	# File → print → select profiles → peak list
		+	# Extract data: data set → select which one → edit → copy data → measurement data → notepad → paste
		+
		+
		+	<u>Data Collection from DSC</u>
