From material substance to shape to property

Wed, 19/11/2014 - 11:00am to 12:00pm
Physics Conference Room (S13-M01-11)
Event Type: 


Connecting the underlying chemical processes with the growth and emergent form remains an unsurmountable problem in life sciences [0]. In materials research, the current outlook is more optimistic. Establishing such connection, from the basic interatomic forces to growing nanostructure shape and properties becomes a real possibility. We will discuss several important examples of current interest including theory of carbon nanotubes chirality [1], growth and morphology of graphene [2] and other important 2D-materials [3], including the shape of equilibrium or growing islands, polycrystallinty and grain boundaries, and the unexpected functionality they bring about in electronics, magnetism, energy storage, and catalysis.
