CEMSE Dean's Distinguished Lecture | High Speed Imaging at the Nanoscale

Start Date: November 8, 2015
End Date: November 8, 2015

By Prof. Kamal Youcef-Toumi (Massachusetts Institute of Technology,Cambridge, MA, USA)

Atomic Force Microscopy is a powerful method used in various areas of nano-sciences and nano-engineering. However, many new applications, particularly nanotechnology and biotechnology, require both high speed and high precision imaging. The ability to image nanoscale features at high imaging rates opens many new opportunities. It will change the way we explore the nanoscale world and enable new discoveries. The presentation covers first a few methods for “seeing” at the Nano-scale. Then it raises key issues including effects of resonances, coupled scanner dynamics, handling high data rates and real time control. Some of our essential contributions that made high speed imaging possible are presented. They include scanner design, instrumentation, real-time system identification, real time control methods, and cantilevers with integrated sensing and actuation.  The presentation will conclude by reviewing some of our recent results which include molecule-by-molecule DNA sequencing, characterization of textured surfaces for dust repellent coatings for solar panels, quality control for high density memory, and nano-scale video imaging of etching and deposition processes. The developed technologies enabled an increase in the scan rate of more than 4000 lines per sec, data rates of 20 Mega samples/sec, and large scanning areas of 120µmx120µm.
Biography: Kamal Youcef-Toumi joined the MIT Mechanical Engineering Department faculty in 1985. He earned his advanced degrees (M.S. 1981 and Sc.D. 1985) in Mechanical Engineering from MIT. His undergraduate degree (B.S. in Mechanical Engineering awarded in 1979) is from the University of Cincinnati. Professor Youcef-Toumi's research has focused primarily on design, modeling, simulation, instrumentation, and control theory. The applications have included manufacturing, robotics, automation, metrology and nano/biotechnology. He teaches courses in the fields of dynamic systems; robotics; precision machine design and automatic control systems. Professor Youcef-Toumi was selected as a National Science Foundation Presidential Young Investigator "in recognition of research and teaching accomplishments and academic potential." He served as a member on several professional committees of The National Science Foundation, Chairman of the Information Technology program within The Arab Science and Technology Foundation, Member of the review committee for European Union funded Network of Excellence for Innovative Production Machines and Systems, Member of the Scientific Committee for Qatar Foundation Annual Research Forum, Head of the Controls, Instrumentation and Robotics Area in the Mechanical Engineering Department at MIT, Member of the MIT Council for International Programs, and Research and Strategy Advisor for Qatar Computing Research Institute. He is the Co-Director of the Center for Clean Water and Clean Energy at MIT and KFUPM. Professor Youcef-Toumi has served as a consultant for a several companies including AT&T Bell Laboratories, EDO Corporation, Varian Radiation Division, Gillette Corp., Delta Search Laboratories, Jentek Sensors, Morgan Stanley Co., General Electric, TEKES - National Technology Agency of Finland, Jordan Hospital, Mitsubishi Electric Corp. Penn State University-College of Medicine - Cancer Institute. He is a member of IEEE and an ASME Fellow. He served as Chairman of the ASME Dynamics Systems & Control Division Robotics Panel. He was an Associate Editor of the ASME Journal of Dynamic Systems Measurement and Controls, the International Program Committee Chairman for the 2010 IFAC Symposium on Mechatronic Systems, and an Associate editor of the ASME's Dynamic Systems and Control Division (DSCD) Conference Editorial Board. He has served as Editor of several symposia/conference proceedings. Professor Youcef-Toumi is the author of over 200 publications, including a textbook on the theory and practice of direct-drive robots. He holds over 30 registered/pending patents. Professor Youcef-Toumi has been an invited lecturer at over 160 seminars at companies, research centers and universities throughout the world.
