72nd ACS Colloid & Surface Science Symposium

P

ennsylvania State University, State Col­ lege, will host the 72nd American Chemical Society Colloid & Surface Sci­ ence Symposium from Sunday, June 21, to Wednesday, June 24. The technical program in­ cludes 540 papers. The Penn Stater Conference Center Hotel will be the venue for all events.

Plenary Lectures Two plenary lecaires will be presented during the symposium. The first, "Layer-by-Layer As­ sembly of Organic and Metal Oxide Molecules by Alternate Adsorption and Surface Sol-Gel Process," will be presented by Toyoki Kunitake, Kyushu University, Japan. The second, "From Perforated Vesicles to Dispersed Reverse Phases—A Random Walk among Self-Assem­ bled Lipid Structures," will be presented by Mats Almgren, University of Uppsala, Sweden. The 1998 recipient of the ACS Division of Col­ loid & Surface Chemistry's Victor K. LaMer Award will also present a plenary lecture.

Technical Sessions Twelve symposia have been organized for the conference: "Self-Assembled Monolayers and Multilayers," "Surfactant Self-Assembly and Applications," "Adsorption at Solid Surfaces," "Solutions of Bile Salts and Biliary Colloids," "Production and Application of Metal Nanoparticle Arrays," "Surface Chemistry and Tribology," "Colloids in Separations and Environ­ mental Technologies," "Colloids in Materials Processing," "Nucleation," "Fundamental Re­ search in Surface Science," and "Colloids in Food Technology, Pharmaceutical Technolo­ gy, and Biotechnology." A special symposium, "Emulsions, Foams, and Thin Films: Honoring Darsh T. Wasan" will also be held.

Poster Session and Exhibition There will be a poster session on Monday evening relating to all the symposia themes as well as general topics in colloid and surface science. Also on Monday evening, an exhibi­ tion of colloid and surface science instrumen­ tation and books will be presented by compa­ nies serving the colloid and surface science community.

Special Events There will be a welcoming reception on Sun­ day evening, a Monday evening reception dur­ ing the poster session and exhibition, and a symposium banquet on Tuesday evening.
