Developing Bonds Between Women Chemists in the U.S. and Korea

Over the past decade we have witnessed many exciting advances in the laboratory towards the development of new materials, in the area of molecular architecture and nanoscience, as well as in the development of new “bio-inspired” materials that seek to emulate materials that have evolved in nature. Many of these new materials are being made in more complex and reactive environments than in the past where vacuum or clean-room conditions were traditionally used. The assembly of thin films at liquid/solid and liquid/liquid interfaces fall into this category as well the multitude of unique nanostructured materials that assemble in solvents and at surfaces. We have also begun to see advances in moving the synthesis and assembly of these materials to more environmentally benign solvents, such as in aqueous solutions, where complex interactions between the water solvent and the largely hydrophobic material can play a controlling role. This increased complexity of the materials growth environment is usually accompanied by less predictability, often because of our limited knowledge of the fundamental molecular interactions that lead to the assembly and stability of molecules at these interfaces. This presentation gives an overview of ongoing research in my laboratory that is aimed at obtaining a molecular level picture of the adsorption and assembly of surfactants, nanoparticles and macromolecules from aqueous solution to both solid and fluid surfaces. We employ both experimental and computational methods to unravel the complex structural, reactive and bonding interactions present at these interfaces. These fundamental studies have direct relevance to many important areas of technological interest including environmental remediation, waste water treatment, green chemistry, materials growth, surface wetting and hydrophobicity, and macromolecular assembly.
