• Descrição:

  Over the last three decades, carbon nanostructures have been intensively researched. Due to these investigations, materials with extraordinary mechanical, electronic, and thermal properties have been discovered. Examples include fullerenes, carbon nanotubes, and graphene. In this seminar, the main topic of discussion will be the mechanical properties of carbon nanomaterials. However, the focus will not be on the search for stronger materials, but rather on the investigations to control other properties through mechanical stimuli. In the first half of this seminar, we will briefly discuss how electronic and thermal properties change in two-dimensional (2D) materials with the application of strain. Then, I will present results that detail how to use strain to control adhesion in a 2D covalent organic framework, as well as a possible application of this effect. In the second half of this seminar, the topic will be the use of mechanical stimuli to displace nanostructures in a direction of interest. We will discuss why it is so difficult to control motion at the nanoscale, and proposals that attempt to solve this problem. Finally, I will present recent results that show how curved nanostructures can be used to direct motion at the nanoscale.
