Molecular biomimetics
Calcium carbonate phases are ubiquitous in the earth and in many organisms, and the formation of geochemically and biologically important crystalline calcium carbonate phases (calcite, aragonite, vaterite, and ikaite [CaCO3·6H2O]) has long been a topic of great interest. Amorphous calcium carbonate (ACC) can be a critical transient phase in the formation of inorganic CaCO3 and in biomimetic mineralization. Critical questions about the role of proteins and organic molecules in the formation of inorganic CaCO3 in living organisms include the molecular scale structure, dynamical, and chemical behavior of these molecules and how they interact with ions and water. Several proteins that are responsible for the formation of shells in bio-mineral systems bind to amorphous nanoparticles and lower or remove the energy barrier to crystallization. We use computer simulation techniques to mimic protein mediated biomineralization processes to generate biomimetic materials with specific properties.
Bioethanol Production from Plant Biomass
Celluase enzymes produced by some bacteria are potent candidates for the production of bioethanol, a possible alternative to fossil fuel, through degeneration of cellulose obtained from biomass. The major component of plant biomass is crystalline cellulose that form the cell wall in plant cells and provides stability to the plants. This structural property of cellulose along with the coating of other polysaccharides, e.g. lignin, pectin, and hemicellulose, makes it recalcitrant to easy decomposition. We study the molecular level details of these enzymes using computer simulations.
