New Materials Focus of Nanotechnology Research Project
South Dakota Tech researchers are using nano-sized powders to synthesize new and advanced composites by combustion technique that could improve products in the aerospace, automobile, defense and medical industries.
Dr. Jan Puszynski, dean of Tech’s College of Materials Science and Engineering, Dr. Jacek Swiatkiewicz, a research scientist in the Chemistry and Chemical Engineering Department, and two students are collaborating on the National Science Foundation-funded project. The three-year, $330,000 project, is in its second year.
The project’s goal is the fundamental advancement of knowledge in the formation of ceramic-ceramic and ceramic-intermetallic composites and functionally-graded materials using nanopowder reactants. These materials could be used for manufacturing of structural components, mechanical parts and in other situations where conventional materials fail.
“There is a need for new advanced materials that can perform at extreme temperatures and in corrosive environments while maintaining mechanical strength,” Puszynski said. “Ceramic-ceramic and ceramic-intermetallic composites with submicron grain structure can exhibit unique and attractive mechanical, thermal and electrical properties.”
The project is part of Tech’s growing body of research work in the area of nanotechnology. Nanotechnology is an umbrella term that covers many areas of research dealing with objects measured in nanometers. A nanometer (nm) is a billionth of a meter, or a millionth of a millimeter. A human hair’s diameter measures about 200,000 nanometers.
��The research is very fundamental,” Puszynski said. “At this point, we are attempting to discover what is possible.��
