This week we were learning how to use codes and know their functions. My mentor was explaining how to use them properly. These codes can be used to form a wide variety of functions, like you can use them to control laboratory tools and much more.
During the week, we had to replace a device called Arduino. We first programmed this device, and made a circuit with LEDs to simulate the function we wanted it to do. This, to change the type of current we wanted to apply in graphene.
After that, we proceeded to prepare some samples of graphene. The process was that we had to cut some samples of silicon, then in a container with water were a few layers of graphene floating and we had to put them on the top of the silicon samples. As a next step, we put the samples with graphene in an oven so that it would hold well to the surface. After a few hours in the oven, they are ready to perform electrical resistance tests.

On the weekend I went to the aquarium. This second week I enjoyed what we did, but we saw more theory than working in the lab. I like what I’m doing, it’s very interesting, and it’s getting more interesting.
