| [* black] So, what has changed? First, the dome cover membrane | |
| [* black] In the 2018 model, the cover membrane is semi-opaque and tackier. It feels like silicone when you rub it. The new model uses a clear membrane that is crinkly and smooth to the touch. | |
| [* black] To confirm that the materials are different, we performed a Fourier Transform Infrared Spectroscopy (FTIR). Shoutout and thanks to whoever helped us! | |
| [* black] FTIR spectroscopy works by shining light at a material and measuring how much light is absorbed and at what wavelengths. This data acts as a fingerprint for the material, allowing for identification | |
| - | [* black] The spectrographs (is this the right word??) for the two membranes show that they ''are'' different! |
| + | [* black] The spectrographs (is this the right word??) for the two membranes show that they ''are'' different to each other! |
| [* black] By comparing the material spectrographs to known materials, we are guessing that the 2018 model uses _______ while the 2019 model uses ________ | |
| [* black] What does that mean? Insert analysis here. |
