The outcome of this independent study is different from what I have planned at the beginning of the semester due to the COVID-19. Since the lab has been closed after the spring break, I was not able to continue the project on the fabrication of a metallic droplet generator, which is to be used to conduct research on to analyze the cooling rates and impact dynamics of molten metal droplets. After the spring break, I helped analyze the data for the research on the wettability of graphene, which I have been working on since last summer. Therefore, this report summarized my wiring design of RTDs in chamber, thermocouples in crucible and PID controller for the droplet generator project. It also included my analysis on surface tension of diiodomethane and ethylene glycol from 25-85 and the contact angle of graphene in these two liquid for the graphene project. The only step left for the design of droplet generator will be re-drilling the holes on Teflon block. For the graphene project, our next steps will be finishing the data analysis part for all five liquids: water, glycerol, hexadecane, diiodomethane, and ethylene glycol; then a surface energy equation for graphene will be derived.
