This week I got to work on the optical microscope and look to see how uniform the polymer film samples were. The pictures underneath the microscope were sooo cool! So needless to say this has been my favorite week–because that has been my absolute favorite part. I also ran a large series of films through the ellipsometer and washed them in toluene and I am currently working on measuring them all again for their residual thickness.  I also get to work on the optical microscope again today to see what the films look like after washing. I am soo pumped! And of course as things start to get really interesting, of course it’s time to end my stay here in this lab *sigh*. All in all it was a neat experience and I will miss it, but hopefully I can take back being a stronger researcher to my students. I wish you all a wonderful school year, and it was so nice working with you all! Here are some pictures of the films under microscopy for your viewing pleasure:
