Processing and Characterization of Nanomaterials
CAMP Professor Dipankar Roy is using electrochemical methods, combined with other state of the art analytical techniques, for the processing and characterization of various nanomaterials. Energy storage and conversion are main areas for applications of these materials, and center mostly on the development of advanced all-solid-state rechargeable batteries and electrochemical super capacitors. The research involving battery materials focuses on various nanoceramics, and is associated with an ongoing CAT Development Project with NanoDynamics and MetaMateria Partners.
Roy ’s group studies novel ionic liquids (ILs) and carbon nanotubes (CNTs) for applications in super capacitor energy devices. Some of this research is conducted in collaboration with Professor Ruth Baltus, Chair of the Chemical and Biomolecular Engineering Department at Clarkson University. Another focus-area of Roy’s current research is chemical mechanical and electrochemical mechanical planarization (CMP and ECMP, respectively). This work, performed in collaboration with Distinguished University Professor and CAMP Director S.V. Babu, mostly involves the development of advanced slurries and electrolytes for applications in CMP/ECMP of interconnect structures containing new ultra low-k materials. Part of this CMP project is supported by the Semiconductor Research Corporation through IBM. More information about Professor Roy’s research can be found at: http://www.clarkson.edu/~samoy/
Professor Privman’s Group Develops a Variant for the Random Sequential Adsorption Model

The random sequential adsorption model has found many applications, notably in irreversible surface deposition of microscopic particles. Recent work of Professor Vladimir Privman’s group has resulted in the development of a variant for the random sequential adsorption model. It is appropriate for studying damage accumulation in materials, with an emphasis on multi-cracking; see http://arxiv.org/abs/0712.3567 for details. Figure 4 illustrates a calculation of the density of the damaged regions, G(t), as a function of time, t, and other system parameters.
CAMP Professor Dan Goia Receives Promotion
Professor Dan Goia
Associate Professor Dan Goia has been promoted to Full Professor in Clarkson’s Department of Chemistry and Biomolecular Science. Goia obtained his M.S. degree from the University of Cluj ( Romania) in 1980 and his Ph.D. degree from Clarkson University in 1998. After a successful career in industry, he joined Clarkson University in October 2001. Prior to his move to Clarkson, Professor Goia worked for more than 20 years in the research organizations of several companies involved in the development and manufacturing of fine particles (pigments, metals, ceramics, etc.); his latest position being R&D Director in the Electronic Materials Division of dmc2 Corporation, formerly Degussa Corporation. For the last two decades, his research has been focused on the preparation, characterization, and modification of micrometer and nanometer size simple and composite metallic particles for electronic, catalytic, metallurgical, optical, and medical applications.
While at Clarkson, Goia has been particularly interested in the elucidation of the fundamental mechanisms governing the formation of highly dispersed uniform particles in homogeneous solutions. In this area he has authored 28 publications and 14 patents and enjoys worldwide recognition in both academic and industrial circles, as testified by the frequent invitations to lecture both in the US and abroad. Since his arrival to CAMP, Clarkson University has received over $8,500,000 in external funding for research related to metallic particles. A large part of this funding was provided by the U.S. Army for developing advanced materials which can effectively obscure IR radiation. This research has resulted in several novel materials which have met U.S. Army performance targets and are presently scaled up to industrial volumes. Another important focus of Professor Goia's research is the development of precious metals for electrocatalysts, energy conversion and storage applications. In the area of proton exchange membrane fuel cells (PEMFC), he has already received a $540,000 multi-year grant from Umicore/Germany to develop highly dispersed Pt and Pt alloy nanoparticles deposited on various substrates. Professor Goia has also received $350,000 from NYSTAR and NanoDynamics for research involving the development of precious and base metal electrocatalysts for solid oxide fuel cells (SOFC).
