Integrated Nanostructured Systems

Carbon black, with 30 nm nanoparticles, as shown, is even more effective than single-walled carbon nanotube for making pastes for improving thermal contacts.

Application of materials science and engineering to develop, improve, test and understand materials for technological needs.

The Chung group has developed nanostructured pastes for improving thermal contacts (for electronic cooling), carbon fiber polymer-matrix structural composites with nanostructured interlaminar interface for improved thermal conductivity (for aircraft cooling) and for improving vibration damping (for structures), nanostructured cement-based materials (for multifunctional structures), nanostructured carbon films of high electrical conductivity (for electrodes), nanostructured materials for electromagnetic interference shielding, and applications of carbon nanofiber in batteries.

Mechanical testing systems, optical microscope, metallographic specimen preparation facility, contact angle analyzer, thermal analysis system, electromagnetic interference shielding effectiveness testing system, surface area analyzer.
