Professor R. Shankar Subramanian is working on interfacial phenomena and their influence on transport problems, especially on drop motion on a horizontal solid surface.
In collaboration with his graduate student, Vikram Pratap, and undergraduate honors student, Chris Gilbert, Professor Subramanian is studying the motion of a liquid drop on a solid surface because of the action of a temperature gradient. Such motion can be important in applications such as the removal of debris in ink jet printing, and in moving drops from one place to another in microfluidic devices.
Welding/Joining and Research to Assess Engineering Systems Reliability
Chair / Professor Daryush Aidun of the Mechanical and Aeronautical Engineering (MAE) Department and his group at Clarkson are carrying out various research activities related to welding/joining of materials. His work includes Friction Stir Welding of Al to Al, Friction Welding of Dissimilar Tubing such as Al to Cu, and the Internal Orbital GMA Welding Process which can be used to coat the interior of less expensive and low corrosion resistance piping with high corrosion resistant alloys (such as coating the interior of A36 steel with 310 stainless steel). Also Professors Aidun and Marzocca are working to design a remote controlled welding system for an unmanned aerial vehicle (UAV) to investigate the effect of altitude and maneuvering on the weld solidification and the overall weld quality. In addition, both Professors are investigating the reliability and life assessment of GE Energy Systems’ gas turbine intercooler systems.
CAMP Professor Roshan Jachuck’s Process Intensification and Clean Technology Group Continue to Make Progress
The Process Intensification (PI) Group led by Dr. Roshan Jachuck has made considerable progress in the last two years. Based on the concepts of PI, advanced reactor technologies have been developed. The Group has successfully carried out lab and pilot scale demonstrations, which are environmentally friendly, for a range of continuous processes including biodiesel production. Field effects such as microwave, ultrasonic, ultra violet radiation and centrifugal forces are routinely used to combine advances made in Green Chemistry with PI concepts in order to deliver Green Engineering. Industrial and government sponsored projects are currently underway. Some involve energy production, energy efficiency, and pollution prevention in various processes including those used in the food industry. Other work includes the continuous production of metallic nanoparticles, tailored polymer processing, and green processing for the semiconductor industry. During his three years at CAMP, Professor Jachuck has attracted research dollars totaling $ 1.5 million. He is currently working with several New York State companies including the SI Group, Starfire Systems, Inc., Knowlton Technologies, Kodak, ND Fusion, NanoDynamics and Losurdo Foods, Inc.
Several of Professor Jachuck’s research students have also been successful in receiving prestigious scholarships. Last year Mr. Samuel Gorton was the recipient of the Goldwater Scholarship and this year Mr. Karel Hartlieb (a Graduate student from the University of Western Australia) has received a Fulbright Scholarship to spend eight months in Jachuck’s laboratory. In addition, this year Mr. Dinesh Selveraj successfully completed his internship at NXP, and has been hired by this company. The unique nature of his work was announced in a press release by the DEC ( http://www.dec.ny.gov/press/36772.html).

Research Using Abrasive Water Jet Technology and Other Projects
Dr. Benjamin Dorfman joined CAMP in 2004 as a Research Professor in Clarkson University’s Department of Physics. After successfully transferring his initial synergetic carbon QUASAM technology to NanoDynamics, he developed a new approach to ultra-high pressure abrasive water jet (AWJ) technology. This is the most universal and fastest growing machine tool worldwide. With support from grants provided by NYSTAR, NYSERDA, and Empire Development, the transfer of this technology from Clarkson University to NY Industry is in the crucial pre-commercial state of development under the leadership of Steve Rohring, United Materials International. This complex, cross-disciplinary and cross-industry system development has attracted practical interest and close partnerships with large, medium and small business companies, and research centers in the USA, Germany, Austria, the Netherlands, and Sweden. While continuing research in the framework of these technology transfer projects, Professor Dorfman and Dr. Lichun Zhang have discovered certain potentially important surface phenomena that suggest additional possibilities for AWJ technology. Also Professor Dorfman and Dr. Zhang are carrying out various studies using volcanic glass (obsidian from different locations) that may result in a prototype for novel artificial glass.
Dr. Dorfman continues his system analyses of development in computer technology and nanotechnology. He is the author of a few monographs published in these fields in Russia during the 1960s – 1980s. In addition to a few monographs, books, and hundreds of research articles, he has two recent book publications in Russian. They are titled “Reminiscences of Atlantis,” NY, 2005 and “The Times, The Clouds, The Eternity,” NY, 2007.
