Over these last weeks the viscosity measurements over the temperature range from 5 to 85 degrees Celsius for the rest of the family. The data was then processed over the following weeks for these members. The members are C4, C6, C8, and C10 methylimidazolium(MIM) TFSI. The data was processed with accordance to the Compensated Arrhenius … More Ben Clark Update- February 28th, 2016
I am still working towards completing SSRS with our known standard (Silicon chip). However, I am MUCH closer now than I was before! This week, I successfully wrote and fit a function for the derivative spectrum of the Silicon stretch peak, since we are performing a “pseudo-subtraction” regarding the peak and SSRS (which gives a … More Caren Sullivan–Feb 26th, 2016
This week I successfully took shifted Raman data of the Si chip via moving the calibration grating manually by 20 inverse cm. I was able to move the 520 cm^-1 Si peak to 540 cm^-1 and 560 cm^-1, respectively, by changing the grating by almost the same amount (20 cm^-1). I now realize when actually … More Caren Sullivan–Feb 19th, 2016
This week I was able to get the Raman calibrated again, so I have been busy taking spectra! First, I conducted an experiment on a slice of the parchment I purchased to see if I would damage the parchment from too intense/long of 532nm laser exposure. I divided the parchment into a chart: vertically, the chart … More Caren Sullivan-Feb 11th, 2016
I was extremely busy this week finishing up grad school apps so unfortunately not a lot happened in the lab. That being said, the Raman is back up and working properly (so I hear)! Also, I found some great SSRS articles that reference our original article by S.E.J. Bell. Since the articles are from the … More Caren Sullivan–Feb. 4th, 2016
This week we switched gears slightly as to accommodate the timeline for my senior project for this term. We collected viscosity measurements for 1-butyl-3-methylimidazolium TFSI over the temperature rang of 5 to 85 degrees Celsius.
