Vacuum and Electrolytic Plasma-Assisted Processing

We have developed and work on surface engineering by novel (patented) vacuum and electrolytic plasma-assisted processes that can produce functionally gradient layers and surface films/coatings for a wide range of applications from aerospace to biomaterials. Vacuum processes are centered on intensified plasma-assisted nitriding for surface hardening, coating and surface modification treatments addressing surface-sensitive properties such as tribological, corrosion, biocompatibility and etc. Electrolytic plasma processing is a relatively new process that can combine effective cleaning and coating in a wet environment. Present activities are concerned with replacement of toxic electroplated Cd, Cr and Ni with environmentally friendly coatings.

Multifunctional, Nanoparticle and Multilayered Nanocomposites

In the nano-composite thin films area, we are focusing on nano-particle and nano-layered multifunctional films where the components act synergistically and can offer a combination of desirable properties (mechanical, tribological, magnetic, electronic, electrochemical, biological, biocompatibility, etc.). For example, one of the nano-composites we are currently pursuing is multifunctional Co-DLC (diamondlike carbon) films where self-assembling of 5 nm diameter Co nanorods can take place providing an excellent potential to use these films in high density storage, biosensors, MEMS, microdevices, etc. We also pursuing the possibility to use the self-organized Co structures as a nanocatalyst to grow guided arrays of single-wall CNTs that can lead to really exciting electronic applications.

Self-organized, Epitaxial Oxide Nanostructured Films

The last few years, we were the first to observe and report self-assembling in epitaxial perovskite -type oxide films. We currently explore ways to manipulate this process and to develop a novel "bottom-up" nanofabrication technique for sensors, optical, electronic and magnetic nanodevices. These research activities are supported by a NIRT/NSF grant.
