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 sixth 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 Study of Ultraviolet Air Purification Systems

Cross bacterial contamination among patients in hospitals and medical facilities has been a serious issue.  Ultraviolet Germicidal Irradiation (UVGI) purification systems can affectively reduce these bacterial contaminants, but the efficiency of the systems is dependent on the airflow in and around these UVGI systems.  Professor Goodarz Ahmadi, in collaboration with researchers at Syracuse University and at Haledyne, is working on improving the performance of the UVGI system developed by Haledyne LLC.   The specific objective is to perform computational and experimental studies on the nature of air distribution around the device in a room.  The goal is to improve the efficiency and optimize the energy usage of the UVGI system.

Investigation of Particle Resuspension by Walking on Floors in an Indoor Environment

Indoor air pollution is believed to be the cause of many respiratory health issues. The general goal of this project is to provide a fundamental understanding of particle resuspension in an indoor environment and its contribution to indoor air pollution.  However, the effects of nature, of foot motion, the gait cycle, and in particular the electrostatic forces on particle detachment and resuspension, are not well understood.    Professors Ferro and Ahmadi are using computation and experimental studies on the motion of a mechanical foot and the resulting resuspension from the floor.  Particular attention is given to the electrostatic forces and airflow that are generated by walking on floors and their effects on particle detachment in indoor environments. 

Computational and Experimental Study of Airflow and Particulate Pollutant Transport and Concentration around the Center of Excellence Building

Professors Ahmadi and Bohl are studying the airflow conditions and particulate pollutant transport around the Center of Excellence Building in Syracuse.   A scaled model of the building has been tested in the wind tunnel.  Airflow velocity and turbulence intensity around the building model were measured in the wind tunnel using the PIV technique.  A computer model for the airflow condition has been developed and was verified by comparisons with the wind tunnel data.   The computer model provides a tool for analyzing the airflow around the actual building.  In particular, the particulate pollutant dispersion near the building is being assessed and the results are to be compared with the field data.

Distinguished University Professor S.V. Babu is an expert in the field of Chemical Mechanical Planarization. He has 28 patents issued and is a coauthor of over 230 professional publications. Also he has supervised a number of graduate students, 77 in all. His 40th Ph.D. student, John Bogere Matovu, just successfully defended his doctoral thesis on October 21, 2013. John’s dissertation was titled “Chemical Mechanical Polishing of InP, GaAs, and InGaAs Films and Related Environment and Safety Aspects.” Five of Professor Babu’s doctoral students and six of his 37 MS degree students completed their work at IIT Kanpur. The others finished their degrees at Clarkson University.

Professor Babu co-organized many symposia and delivered Keynote talks at many conferences. In addition, he is a recipient of the 2004 IBM Faculty Award and was honored in 2010 with a Visiting Professorship for Senior International Scientists by the Chinese Academy of Sciences, Shanghai.
