t the national meeting in Washington, D.C., 27 of the society's techn i c a l divisions, one secretariat, and four committees will participate in more than 619 technical sessions. More than 5,500 papers will be presented. Seven areas of concentrated programming have been identified for this meeting. In the technical program that begins on page 58, symposia that fall within these themes are identified by a symbol that immediately precedes the

ACS support for divisions and local sections An ACS Presidential Task Force has been created to review the society's support to local sections and divisions, including issues of allocation and council representation. The task force sponsored discussions of these issues at sessions of Local Section and Divisional Activities Committees during the San Francisco national meeting, and will do so at the Divisional Officer's Caucus during the meeting in Washington, D.C. Any ACS member wishing to comment on issues relating to the task force's charge may do so before July 31 via e-mail (acssupport® acs.org), or by mailing comments to American Chemical Society, Office of the Secretary, 1155— 16th St, N.W., Washington, DC 2 0 0 3 6 , Attn: Support 5 2 JULY 24,2000 C&EN

session title. A symbol key appears throughout the program. The ACS presidential events—two plenary sessions, three panel discussions, and a reception—will focus on successful models that can be used in both academe and industry to accelerate the momentum of achieving minority representation in the chemical sciences. The first plenary, "Accelerating the Momentum: Successful Tools for the 21st Century," will be highlighted with opening remarks by Warren F. (Pete) Miller of Los Alamos National Lab and closing comments on diversity by retired Army Gen. Colin L Powell. The second plenary session is titled "Online Preprints: Implications for Chemistry." National Science Foundation Director Rita R Colwell will speak on her agency's role in chemical research during a presidential reception celebrating NSFs 50th anniversary. Other special events include a Technology Transfer Fair, where participants will be invited to make a technical showand-tell presentation that describes their technology development Russian nuclear scientist Aleksandr Nikitin will discuss his acquittal on treason and espionage charges by the Russian Supreme Court And Sci-Mix—an interdivisional poster session and mixer—will be held Monday evening from 8 to 10 PM. The exposition will be open Monday through Wednesday, with more than

260 companies exhibiting a wide range of products and services of interest to the chemical community. Classification of registrant
