When the size of a particle is smaller than a characteristic length (e.g., electron mean free path), then the properties of the particle can be significantly different from its bulk properties. Zinc oxide nanoparticles exhibit novel optical properties (band gap enlargement) as their particle size decreases. The synthesis and characterization of such nanoparticles is essential for the development of new technologies exploiting the novel size-dependent properties of nanoparticles.
Patterned surfaces are of interest for a wide range of applications including flat panel displays, data storage device, and sensors. Photolithography is a common method used to create patterned structures although the process can be quite expensive and require several fabrication steps. Novel unconventional lithography techniques are under development.
The gecko adhesive systemconsists of a complex hierarchy of structuresranging fromcentimeters down to nanometers.The later provides sufficient compliance to the system to allow for intimate contact with surfaces of different degrees of roughness, thereby allowing strong adhesion through van der Waals interactions. In addition to promoting strong adhesion, the gecko adhesive system has several other properties which make it attractive for future technologies. Understanding the gecko adhesive system would allow for the fabrication of dry adhesives inspired by the gecko.
B.S., Carnegie Mellon University, 1999
Ph.D., Johns Hopkins University, 2005
Dr. Pesika attended Carnegie Mellon University where he obtained his Bachelors Degree (1999) in Chemical Engineering and French. He then obtained his Ph.D. (2005) in Chemical and Biomolecular Engineering from Johns Hopkins University where he developed a novel microfabrication technique involving microcontact printing and electrochemistry. The latter led to a provisional patent. Following his Ph.D., Dr. Pesika joined the University of California in Santa Barbara as a postdoctoral fellow.
To date Dr. Pesika has authored over 30 peer-reviewed articles and presented his work at several professional conferences. His honors include a Graduate Student Fellowship from NASA to study the nucleation and growth of zinc oxide nanoparticles and Postdoctoral Fellowship from the Intelligence Community to study the nanoscale contact mechanics of geckos. Dr. Pesika currently holds the Robert and Gayle Longmire Early Career Professorship in Chemical Engineering.
