Description
Civic education in America should be focused on empowering future generations to take full advantage of their rights as citizens and realize their potential to incite change. Even at a young age, it is important that we educate children on what it means to be a United States citizen so that they can begin cultivating their personal political experience. As soon as the child is at the age where they can begin to understand basic political and governmental concepts, they should be encouraged to start thinking about their roles as citizens in a Democratic government. More often than not, young adults express that they wish they had been exposed to the political climate earlier on in life. When a lot of these adolescents reach voting age, they are woefully under-educated and apathetic towards their participation in the civic sphere. This activity booklet was designed to not only educate but also empower and inspire kids, and to really get them excited for their futures in the civic sphere.

Description
Graphene is a very strong two-dimensional material with a lot of potential applications in microelectromechanical systems (MEMS). In this research, graphene is being optimized for use in a 5 m x 5 m graphene resonator. To work properly, this graphene resonator must have a uniform strain across all manufactured devices. To reduce strain induced in graphene sheets grown for use in these resonators, evaporated platinum has been used in this investigation due to its relatively lower surface roughness compared to copper films. The final goal is to have the layer of ultrathin platinum (<=200 nm) deposited on the MEMS graphene resonator and used to grow graphene directly onto the devices to remove the manual transfer step due to its inscalability. After growth, graphene is coated with polymer and the platinum is then etched. This investigation concentrated on the transfer process of graphene onto Si/SiO2 substrate from the platinum films. It was determined that the ideal platinum etchant was aqua regia at a volumetric ratio of 6:3:1 (H2O:HCl:HNO3). This concentration was dilute enough to preserve the polymer and graphene layer, but strong enough to etch within a day. Type and thickness of polymer support layers were also investigated. PMMA at a thickness of 200 nm was ideal because it was easy to remove with acetone and strong enough to support the graphene during the etch process. A reference growth recipe was used in this investigation, but now that the transfer has been demonstrated, growth can be optimized for even thinner films.
