Colloid and Nanoparticle Research Group
The goal of our program has been to develop an understanding of the formation of uniform nanosize and colloidal particles of various shapes and morphologies. This knowledge is essential in numerous areas of modern technology, medicine, and national security, because many properties of such particles (such as optical, magnetic, catalytic) are strongly dependent on their size and shape.Acknowledgements

"Our research is focused mainly on the synthesis, characterization, and modification of highly dispersed uniform micrometer, submicrometer, and nanometer size metallic particles with well controlled size, morphology, internal structure, composition, and surface properties. While our efforts are mostly concentrated on the development of chemical precipitation processes capable of yielding high performance materials for existing and emerging applications, we also conduct the basic research needed to understand the mechanisms responsible for the formation of uniform metallic particles in solutions.."

"Our research deals with various aspects of finely dispersed matter. Specifically, we have developed procedures to prepare uniform particles of different composition, shape, and size ranging from a few macro-meters to several micro-meters. These materials are used to establish mechanisms of these formations and to evaluate various properties (optical, magnetic, electric, adsorptive, etc.) as a function chemical composition and physical parameters. Finally, they are being used in numerous applications either to stabilize different processes, such as corrosion or chemical mechanical processing, or in diverse applications (medical diagnostics, pigments, ceramics, etc.)."

"Our research interests cover theoretical and numerical modeling in the field of colloid chemistry, soft condensed matter, and statistical mechanics. Specific projects have included the following topics:
"Monolayer and multilayer surface adhesion of colloidal particles, and general modeling of surface deposition and relaxation at surfaces";
"Explaining, and theoretically predicting, the narrow particle size distribution in synthesis of colloid particles by nucleation of precursor nano-crystals and their subsequent growth and self-assembly into larger particles";
"Phenomenological and numerical studies of mechanisms of growth, and shape and morphology selection in synthesis of colloids, polymers, and nano-size particles";
'Particle transport and aggregation to form large composite particles, surface deposits, sediments, and other systems, (e.g., seeding and coating growth processes, and deposition on nano-patterned surfaces)";
"Self-healing materials, including their structure and mechanical properties"."
