Dr. Carl E. Bonner, Jr. graduated from Howard University (Washington, DC) in 1985 with a Master of Science in Physical Chemistry. In 1996, he received a Ph.D. degree in Physical Chemistry from the University of Rochester, Rochester, NY), In 1985-1989, Dr. Bonner worked as a Member of the Technical Staff, at AT&T Bell Laboratories in Holmdel and Murray Hill, NJ. In 1995, Dr. Bonner joined the Chemistry faculty at Norfolk State University where he began as a Assistant Professor, and as teaching faculty, advanced in ranks through Associate Professor to Professor (Department of Chemistry and Center for Materials Research.) In 1997, Dr. Bonner was named Associate Director of the Center for Materials Research at Norfolk State University. He has twice served as its Director. Once, in 2003-3 as its acting Director, and from 2006-2011 as its interim Director. Dr. Bonner has co-authored three book chapters, over 50 papers in peer reviewed journals, over 50 publications in proceedings of professional societies and conference technical digests. Dr. Bonner is a member of OSA, SPIE, and ACS. He regularly serves on NSF panels and site visit teams and reviews papers for many professional journals.
Our group works in the area of plasmonic metamaterials Plasmon enhanced linear and nonlinear spectroscopy, and structural biomaterials. Our plasmonic metamaterials are composite materials composed of dielectric glasses and crystals with metal nanocrystals in a 3-D periodic arrangement. The vision behind our studies in plasmonic metamaterials is to develop structures and methods that enable optical sensing of objects smaller than the diffraction limit. Current applications of plasmonic enhacement can be observed in surface-enhanced Raman spectroscopy and surface Plasmon resonance spectroscopy. Even higher sensitivity can be achieved using plasmonic enhancement of non-linear optical processes such as harmonic generation and four wave mixing. Our current collaborators in the plasmonic metamaterials area are Mikhail and Natalia Noginov (Chemistry and CMR). Recent accomplishments include studies of reduced emission lifetimes of fluorescent molecules in contact with metamaterials. In the biomolecular materials area, we aim to develop new fabrication and coating approaches to control the interactions of surgical and structural implant materials such as CoCr, increasing their biocompatibility and multi-functionality. We use self-assembled monolayers, SAMs, to build an initial coating in which to build further chemical functionality on the surface. We take advantage of strong biomolecular interactions at the implant surface. In this endeavor, our group uses a range of surface spectrocopies including IR-ATR spectroscopy, ultraviolet photo-emission spectroscopy and atomic force microscopy to examine the surfaces. Additionally, we use ultrafast lasers to optically pattern the surface and spatially control the evolving patterns. Our collaborators have included and include, Anil Mahapatro (Witchita State University), Joseph Hall, Chemistry. Recent accomplishments include the development of coatings that control the degradation rate of Mg implants in biological environments and the formation of high fidelity patterns of SAMs using low average power optical laser patterning. Finally, we use a range of computational modeling and simulation tools including, Materials Studio, GROMACS, and DDSCAT to simulate the physical behavior we observe in the experimental systems.
