Abstract

In the context of the "Future Scientists - Prof. Sérgio Muniz Oliva Filho" call, two multidisciplinary and computational research projects at the Scientific Initiation level are hereby presented. The two projects under consideration share a common objective: to examine properties and phenomena of interest in nanoscience and nanotechnology. The first project entails the investigation of the twist-to-writhe phenomenon in twisted nanowires. A paucity of studies in the extant literature addresses the effects of twisting on nanowires. The objective of this project is to verify the mechanisms that relieve torsional stress in carbon nanotubes and diamond nanowires on an atomic scale. The second project is designed to validate a proposed methodology for the transfer of graphene samples that have been cultivated using chemical vapor deposition on copper substrates to substrates with reduced adhesion. This approach is intended to ensure that the integrity of the graphene structure remains uncompromised. Should this method prove effective, it will resolve a longstanding problem for experimentalists by enabling the transfer of graphene between different substrates. The two projects will utilize classical molecular dynamics computer simulations. Due to the absence of analogous studies, the findings of these projects have the potential to be disseminated in international scientific journals. (AU)
