CAMP Annual Report: Page 3

In this Section
CAMP is an interdisciplinary science and engineering endeavor dedicated to research on high-technology materials processing. This research is focused on the production, modification and conversion of matter for which “small” particles, colloidal media and / or surfaces play an important role in the process and /or properties of the final product. Presented here are some highlights of the research during CAMP's twenty third year as a New York State Center for Advanced Technology.


Metallic Particles

CAMP Distinguished Professor Dan Goia is involved in the synthesis, characterization, and modification of ultra-fine and nanosize metallic and metal-composite particles with controlled size, shape, internal structure, composition, and surface properties. These materials are used extensively in established fields such as catalysis, electronics, and metallurgy as well as many emerging applications in medicine, biology, defense, energy generation, and magnetic storage. Presently, Professor Goia has several active government and industrial grants to develop materials for defense applications, PEM (Proton Exchange Membrane) and solid oxide fuel cells, silicon based solar cells, plasma display panels, electromagnetic interference shielding, and metallurgical applications. Other current funded projects involve the development of screen printable conductive pastes for thick film microelectronics, silver dispersions for inkjet printable electronics, core-shell metallic particles for optical and catalytic applications and materials for high capacity energy storage/batteries.


Computational and Experimental Techniques for Human Health and Security in Indoor Environments

Professors Ahmadi, McLaughlin, and Helenbrook, in collaboration with their colleagues at Syracuse University, are developing tools that allow for technology innovations for creating new Intelligent Environmental Quality Systems (i-EQS) for improved health and security in indoor environments.  The specific objective is to develop experimentally validated computational tools for predicting the airflow and transport and migration of aerosols in the indoor environment.   The study will be focused on assessing personal exposure due to exchanges between the breathing zones of occupants in indoor environments.  These tools will provide the basis to develop real time prediction and control systems for intelligent built environmental systems to improve human health as well as for increased security.  In addition, Professor Ahmadi is performing a computer simulation study for the Air Isolation Company in connection with their energy efficient fume hood projects.

Development and Commercialization Plan for a Grid Electrostatic Precipitator

Mr. John Dunn, Mr. James Cunningham, Dr. Xinli Jia, and Professor John McLaughlin are working on the development and commercialization of a grid electrostatic precipitator (GEP) for cleanroom applications. An experimental GEP was manufactured at Cameron Manufacturing & Design, which has supported the project. In March, Cameron received a grant from the Commercialization Assistance Program (CAP) of the Syracuse Center of Excellence (COE) and the Syracuse Metropolitan Development Agency (MDA). The Clarkson team is receiving support through a subcontract from Cameron. The GEP was moved to Clarkson in early April and installed next to a cleanroom that was donated to Clarkson by Cameron in support of the project. Ductwork was installed to connect the GEP to two ceiling vents inside the cleanroom for the purpose of testing the GEP as a substitute for HEPA filters. The test facility is located in the Saint Lawrence County Industrial Development Agency (IDA) Building in Potsdam. Clarkson is renting floor space in the IDA Building for the project. The focus of the work in April-August was on the collection efficiency of the GEP for particles in the size range 0.05 to 0.5 micrometers. Particles in this size range are of concern in the electronics industry since they are comparable in size to device features. The measurements of particle concentration were performed using a Wide-Range Particle Spectrometer.  In July, several modifications to the GEP were made that resulted in substantially higher collection efficiencies – collection efficiencies of 99% have been achieved with relatively little impact on air velocity for a given motor speed. Further modifications are planned in the near future that may yield larger collection efficiencies at larger air velocities. A smaller version of the GEP is being modified to test methods for reduction of ozone that is produced by the corona discharge.



This photo shows the experimental GEP connected to the Cameron cleanroom.  Clean air is blown into the cleanroom through the duct near the top of the cleanroom’s wall.

Mr. Dunn is an inventor who is a consultant for Cameron Manufacturing and a Research Scientist at Clarkson University. Mr. Cunningham is a Business Developer/Principal Consultant with Alliance for Manufacturing & Technology, which is located in Binghamton, NY. Dr. Jia is a Post-Doctoral Research Associate at Clarkson.

 Professor Roy

Professor Dipankar Roy Appointed Chair of Physics


CAMP Professor Dipankar Roy has been appointed the Chair of Clarkson University’s Physics Department, effective July 1, 2010. He joined the Clarkson faculty as an Assistant Professor of Physics in 1989 after studying nonlinear optical techniques of material characterization as a postdoctoral researcher at Cornell University. Roy received his Ph.D. in physics from Rensselaer Polytechnic Institute, where he used Surface Enhanced Raman Scattering to study various electrochemical systems in the fields of catalysis and corrosion.

At Clarkson University, Roy has been promoted through the ranks of Associate and Full Professor, and has served as the Executive Officer of the Physics Department for several years. While teaching a broad range of undergraduate and graduate courses, he has played a key role in the development of the elementary physics laboratories and courses currently taken by most engineering and science major undergraduates at Clarkson. To date, he has supervised ten Ph.D. and six M.S. students, advised numerous undergraduate students, and received Clarkson University’s Outstanding Advisor Award in 1995 as well as in 2006.  Roy has published 88 papers in peer reviewed professional journals, and has presented or contributed to more than 100 seminars and posters at various conferences and symposia. 



Roy’s current research involves the development and characterization of advanced materials for energy storage and conversion, focusing on certain photovoltaic systems, batteries and electrochemical supercapacitors.  He is also studying a range of materials that are relevant for advancing the technique of chemical mechanical planarization (CMP), which is used in the fabrication of semiconductor devices.
