Markita del Carpio Landry was born in Quebec, Canada, to a Bolivian mother and French Canadian father. She grew up a dual citizen of Bolivia and Canada, and when she was 14, her family immigrated to the United States. The challenge of being thrust into a new school while learning English bolstered del Carpio Landry’s love of science and mathematics; she...

Illustration of graphene nanoribbon

Scanning tunneling microscope image of wide-band metallic graphene nanoribbon (GNR). Each cluster of protrusions corresponds to a singly-occupied electron orbital. The formation of a pentagonal ring near each cluster leads to a more than tenfold increase in the conductivity of metallic GNRs. The GNR backbone has a width of 1.6...
