75TH ACS COLLOID & SURFACE SCIENCE SYMPOSIUM

T

HE 75TH ACS COLLOID & SUR-

face Science Symposium will be heldJune 10-13 at Carnegie Mellon University in Pittsburgh. Hosted by the university's Colloids, Polymers & Surfaces Program and the Center for Complex Fluids Engineering, the meeting is sponsored by the ACS Division of Colloid & Surface Chemistry Stephen Garoff of the department of physics and Robert D. Tilton of the department of chemical engineering are cochairs of the meeting. They may be reached by email at [email protected].

ABOUT THE SYMPOSIUM. The sympo sium will highlight the latest advances in the broad domain of colloid and interface science and their technological applications to, for example, biotechnology, materials processing, nanotechnology and environmental engineering. Traditionally organized and hosted by a university, the symposium thrives on strong international SUNDAY AFTERNOON • Plenary Session I S. Garoff, R. D.
