Abstract
We briefly review electronic and optical properties of graphite, graphene and dichalgonides and discuss their strength and
shortcomings. We next discuss how one can engineer electronic, optical and magnetic properties of graphene by control of lateral size, character of the edge, sublattice symmetry, number of layers and carrier density. We describe gate controlled triangular graphene
quantum dots (TGQD) with broken sublattice symmetry and colloidal graphene quantum dots(CGQD). The broken sublattice symmery and zigzag edge in TGQDs leads to a shell of degenerate states at the Fermi level. The filling of this shell leads to nontrivial electronic, optical and magnetic properties controlled by e-e interactions. One of the examples include optical spin blockade and optical control of magnetization in carbon only material system . We next discuss optical properties of colloidal graphene quantum dots with emphasis on band edge exciton and valley polarization.

Title
Natural fibrous proteins as a source for inspiration for the design of novel nano-biomaterials

Abstract
Natural fibrous proteins include families found in natural materials such as wool, silk, in tissue components such as collagen, elastin or
in virus and bacteriophage adhesins. They have long fascinated scientists and engineers due to their mechanical and elastic properties, and considerable efforts have been made in order to
produce artificial materials inspired from these natural proteins.
Repetitive sequences, or "building blocks" derived from these fibrous proteins can self-assemble into well-defined structures (wires, tubes etc.) under mild conditions and are relatively inexpensive and easy to manufacture. Of particular interest is the possibility of using these peptide nanofibers and nanotubes as templates for the growth of
inorganic materials, such as metals, semiconductors, silica, etc. We have been involved for a number of years in the rational design, synthesis and characterization of self-assembling proteins and peptides following identification of building blocks in viral fibers.
This previous work resulted in the identification of a minimal, octapeptide building block that self-assembles into fibrils, and these fibrils have recently been used as templates for the growth of inorganic materials. Controlled manipulation, positioning and nano-microfabrication of self-assembled protein and peptide materials remain a bigger challenge than their design and production. In collaboration with IESL colleagues, we have been using laser - fabricated scaffolds for their controlled positioning. These primary laser-fabricated scaffolds with attached secondary peptide scaffolds could then be used as a support for the directed growth of cells into
biomineralized units.
I will describe how structural insight and basic biochemical studies, combined with practical integration approaches, can result in materials applications ranging from the nano- to the macro-scale.
