When I got to the lab we tested some materials with the EPR MOUSE to see if we could see a signal clearly. We tested a ceramic coin, a flowerpot, coal, and a sample of DPPH. We did get a signal from these but they weren't as clear as the ones we got from the larger EPR machine. Joe gave us a charcoal briquette to test as well. After lunch, we started to plan how we would paint the letters for our project. We had decided that we would first paint the letters EPR and the logo of the MOUSE with paramagnetic paint and while the paint was drying begin the projects with paper currency and the barcode ( which we would analyze using the MOUSE and then create a 1D or 2D image based off the change in signal as we moved the MOUSE over the money or barcode). We then began to paint the design with a mixture of epoxy and the paramagnetic pigment (which was in powder form). This was difficult because the epoxy would dry in 5 minutes so we had to make sure we painted the letters quickly. We also ran out of epoxy when we were in the middle of painting the MOUSE logo. We walked down to the Global Village to buy some more epoxy but the store was closed.
Here are some images of the work I did today:
This is a photo of the EPR MOUSE device when we were collecting data on the ceramic coin (a piece of the coin is on top of the device):
This is a photo of the EPR MOUSE logo we painted. As you can see the middle part of the MOUSE logo is blank because we ran out of epoxy:
