Penghui Ji, a PhD student at Institut National de la Recherche Scientifique (INRS) in Quebec, is recipient of a 2021 SVC Foundation Scholarship.
Penhui writes “This scholarship means a lot to me. Most importantly, it encourages me to be determined to work in the area of scientific research. As well, this scholarship is a powerful endorsement of my value and I feel more confident to continue my investigation.”
“My research focuses on the synthesis of graphene nanoribbon (GNR) films and further improving the purity and controlling the thickness with UHV MBE, in which flux of molecules and substrate temperature can be controlled simultaneously to optimize the growth of thin films. Furthermore, we demonstrated the promotive effect of oxygen in the synthesis of GNRs by lowing the activation temperature by 180℃. In addition, we systematically investigated the effects of oxygen on the surface-confined Ullmann reaction. As a result, the structural transformation from 1D organometallic (OM) chains to 2D OM networks was achieved, which can be used in host-guest chemistry as a novel template.”
