The spatial distribution of a molecular orbital across 10 unit cells of a (5,5) armchair carbon nanotube computed using ab initio methods
The actuators we study are sometimes so novel that no working models exist to enable device design for engineering applications. Therefore, along with my experimental work, I consider developing physical models for nano-structured materials equally important. For example, to understand the actuation in an individual CNT, I have collaborated with Prof. Alireza Nojeh at the University of British Columbia. We used ab initio quantum mechanical methods to compute the dimensional changes created in a single CNT when it is electrically charged. Through continuing this collaboration and forging new ones, I plan to further our knowledge of CNT actuators and work towards the development of totally novel artificial muscles.
