Andrei S. Dukhin is CEO and Co-Founder of Dispersion Technology, Inc., USA. He has been a leader in the development of a new technology for characterizing complex liquids that employs ultrasound for characterizing interfacial chemistry, particle size, and rheological properties of said systems. He has authored three books published by Elsevier, most recently Characterization of Liquids, Nano- and Microparticulates, and Porous Bodies using Ultrasound with Philip J. Goetz back in 2010. He holds 7 USA patents on electroacoustic methods of measuring zeta potential and has published more than 120 scientific papers. He established Dispersion Technology Inc, which installs more than 850 instruments for measuring zeta potential in 30 countries. Dr. Renliang Xu worked for three major particle characterization instrumentation companies in USA and UK, i.e., Malvern Instruments, Beckman-Coulter, and Micromeritics Instrument Corporation, in leading roles associated with zeta potential instrumentation. He has authored 3 professional books: one by Springer and two by Chemical Industry Press in Chinese, as well as five non-fiction books. He holds 3 USA patents on particle characterization and has published 70+ scientific papers.
