211th ACS National Meeting

g ο υ ο ο


NewOrieaiw March 24-28,1996 ext month's ACS national meet­ ing in New Orleans will include more than 5,700 papers orga­ nized into nearly 600 technical sessions that are sponsored by 30 of the society's technical divisions, two secretariats, three committees, and one task force. Four themes have been identified for this meeting: biosciences and technolo­ gy, petrochemicals, methods for sepa­ ration and analysis, and environmental health and safety. In the technical pro­ gram, which starts on page 50, individ­ ual symposia that fall under these themes are identified by a symbol im­ mediately preceding the session title. A symbol key appears throughout the technical program. The meeting provides an opportuntity for ACS to address several professional issues of critical importance to chemists: employment, education, and federal funding for research. The National Em­ ployment Clearing House will premiere an on-site database of registered candi­ dates and employers to facilitate search­ ing for potential interviews. An exten­ sive program in chemical education cov­ ers a wide range of topics. And an open letter to President Clinton and congres­ sional leaders will be available for signa­ ture by members who wish to voice their support for federal investment in R&D—which is no longer a given, as the recent federal budget showdown has highlighted. An ACS presidential event will be held on Sunday afternoon, consisting of a session entitled "R&D Cooperation and Funding versus Global Leadership" and a forum on scientific freedom and human rights. On Sunday evening, ACS President Ronald Breslow will host a party at the Aquarium of the Americas. Another special event at this meeting




is the Tuesday evening recogni­ tion of the 1996 winners of awards administered by ACS. The popular Sci-Mix, a combi­ nation of mixer and poster ses­ sion, will be held Monday evening. As with several previous meet­ ings, program­ ming for this meeting begins on Sunday, March 24, and continues through Thurs­ day, March 28; no sessions or events are scheduled for Friday. Meeting registration includes free ad­ mission to the exposition, at which ap­ proximately 225 companies will have ex­ hibits. Several of the exhibitors also offer
