From material substance to shape to property

Boris I. Yakobson, Rice University, Houston, Texas, USA

Connecting the underlying chemical processes with the growth and emergent form remains 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.
