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

Exposition ζ

Admission to the exposition is complimen­ tary for all national meeting registrants. While planning your schedule in New Or­ leans, reserve some time to visit the national exposition. In addition to functioning as a showcase for the most up-to-date scientific products and services, the exposition also serves as a valuable source of continuing ed­ ucation for meeting attendees. Located in Halls D & Ε of the Ernest N. Morial Convention Center, the exposition will be open Monday, March 25, 9 AM to 5 PM; Tuesday, March 26, 9 AM to 5 PM; and Wednesday, March 27, 9 AM to 4 PM. The exposition will consist of about 380 booths, representing almost 250 companies and organizations displaying items rang­ ing from instruments and books to com­ puter hardware and scientific software. Also displayed will be chromatographic and lab equipment, furniture, and safety equipment. Each exhibiting organization will have technical personnel present to give demonstrations, answer questions, and discuss your needs and interests. Play "Pick 6." Be sure to play the new 'Tick 6" game in the exhibit hall. Attend­ ees will have the chance to win up to $2,000 worth of merchandise from the par­ ticipating exhibitor of their choice. Com­ plete details and game cards will be avail­ able on-site in the registration and badge pick-up areas of the convention center as well as in selected convention hotels. Free Internet Access. ACS will provide free Internet access to meeting attendees in the rear of the exhibit hall in the convention cen­ ter during regularly scheduled exposition hours. A total of 30 terminals will be avail­ able for attendees inside the exposition. Prize and Souvenir Booths. In addition to the comprehensive display of products and servic­ es of interest to the scientific community, there will be sever­ al drawings for prizes and a free ACS souvenir for all visi­ tors to the exposition. Prize tickets can be dropped off at booths 1137,1139, and the sou­ venir may be picked u p at booths 128,130. Admission Requirements. Al­ though admission to the expo­ sition is complimentary for all meeting registrants, a badge is required to enter the exhibit hall. Badges will be mailed to all preregistrants; on-site regis­ trants can obtain a badge in the main registration area of the convention center. Expo-Only Registration. Those not registering for the meeting,

but interested in visiting the exhibits, can ob­ tain an exhibits-only badge for $25. Students with school identification will be charged $5. There will be no preregistration for exhibitsonly attendees; exhibits-only badges can be purchased in the main registration area of the convention center. Exposition Workshops. A series of free ex­ position workshops will be conducted in New Orleans and will cover a variety of topics. Workshops will be held Monday, March 25, through Wednesday, March 27, in the convention center. See pages 134 and 135 for a complete workshop schedule and registration information.

TUESDAY, MARCH 2 6 10:00-11:30 am Undergraduate Symposium II: Industrial Catalysis* • Catalysis plays an essential role in the manufacture of a wide range of products including fuels, lubricants, fine chemi­ cals, pharmaceuticals, and commodity plastics, all of which oth­ erwise would be unobtainable or prohibitively expensive. Two experts will provide examples of how catalytic processes bene­ fit production efficiencies and help minimize wasteful and haz­ ardous "end-of-pipe" byproducts. The scope of both petroleum and environmental catalyses will be explored. For those inter­ ested in large scale production research in industry, this is a must see technical presentation! Hilton/Melrose Room 12:00 noon-1:00 pm Help Plan Future Undergraduate Activities at ACS National Meetings* · Undergraduate students are encour­ aged to make a difference by meeting with the ACS Task Force on National Meeting Programming for Undergraduates to eval­ uate the undergraduate events in New Orleans. The task force is seeking suggestions for future national meeting programs and students who want to get involved in planning these activities. Radisson/Cypress Room

2:30-4:30 pm How To Jump-start Your Career!* (Department of Career Services) · The workshop will provide undergraduate students an opportunity to assess their own values system and commu­ nication styles, which are important insights for career devel­ opment.
