Professor Narayanan Neithalath

Dr. Narayanan Neithalath joined the Department of Civil and Environmental Engineering at Clarkson University in the Fall of 2005. Prior to that time, he served on the faculty of Middle Tennessee State University from 2004 -2005. He received his Ph.D. in Civil Engineering Materials from Purdue University in 2004 and his M.S. in Building Materials and Technology in 1999 from the Indian Institute of Technology in Madras. Neithalath received the Portland Cement Association Fellowship in 2003 and the Bengt Friberg Award for the best paper from the International Society of Concrete Pavements in 2005. He is currently a member of the American Concrete Institute, the American Society of Civil Engineers, and the American Ceramic Society.

Hydrocarbon retention tests on pervious concretes

Professor Neithalath’s main area of research involves cement and concrete materials. His work focuses on structure-property-processing relationships in cement-based materials so as to develop novel cementitious materials for better performance. Currently he is investigating multi-functional cement-based materials like pervious concretes for rain run-off reduction and contamination prevention and the use of industrial waste materials of local and regional origin in concrete so as to ensure sustainability in construction and also to produce performance enhanced concretes. In addition his projects include nano-particle modified high performance concretes.

Professor Suresh Dhaniyala

Dr. Suresh Dhaniyala joined the Department of Mechanical and Aeronautical Engineering at Clarkson University in the Fall of 2002. He received his Ph.D. in Mechanical Engineering from the University of Minnesota in 1998. He has a Master’s degree in Mechanical Engineering from the University of Delaware and B.Tech. degree from the Indian Institute of Technology, Madras. After completing his doctorate, Suresh joined Caltech as a post-doctoral scholar in Chemical Engineering and worked with Professors Richard Flagan and Paul Wennberg. At Caltech his research focused on the development of an innovative aerosol/gas inlet for aircraft sampling that led to unprecedented real-time compositional measurements of semi-volatiles in the upper stratosphere. Suresh Dhaniyala’s Ph.D. thesis was in the field of filtration, involving experimental evaluation and theoretical prediction of inhomogeneous filter performance.

Professor Dhaniyala’s current research interests are in the fields of nanoparticles, particle instrumentation, aerosol sampling, and air quality. Suresh and his group are working on developing several next generation tools for improved real-time characterization of nanoparticles down to 1-2 nm in size (Figure 7). These tools are designed to be compact, portable, and easy to use for applications in personal sampling and large scale ambient monitoring. Theoretical and computational fluid flow modeling were deployed to design these instruments with experiments performed to validate calculations. These projects are funded by NSF and NYSERDA. In Suresh’s laboratory, NSF and NYSERDA support is being leveraged to develop new techniques to characterize the size and composition of nanoparticles emitted from diesel engines. The combination of particle electrical mobility, thermal volatilization, and photoelectric charging techniques make such measurements possible in real-time with compact instruments. Other projects being pursued by his laboratory group include the development of a fast particle sizer and advanced sampler for aerosol-cloud sampling from high-speed aircraft, nanoparticle filtration studies, the development of a new aerodynamic lens system; and the design and development of an advanced instrument for near real-time size-classified characterization of super-micron particles. Funding sources for these projects include NSF, NYSERDA, EPA, and the U.S. Navy.
