Admission to the exposition is complimentary. While planning your schedule in Washington, reserve some time to visit the ACS 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 education for national meeting attendees. New this year: Several ACS divisions will present poster sessions within the exposition hall.
Located in Hall B of the Washington Convention Center, the exposition will be open Monday, Aug. 24, 5 to 7:30 PM, in conjunction with Sci-Mix, which will be held on the exposition floor. Additional hours will be Tuesday and Wednesday, Aug. 25 and 26, from 9 AM to 5 PM, and Thursday, Aug. 27, from 9 AM to noon. A full restaurant and lounge on the exhibit floor offers an economical and convenient place to eat, or just sit and converse with fellow attendees. Free coffee is available in the exhibit hall every morning.
The exposition will consist of about 400 booths, representing about 220 companies and organizations displaying everything from instruments and books to computer hardware and software. Also on display will be chromatographic and lab equipment, furniture, and safety equipment. Each exhibiting organization will have expert personnel on hand to give demonstrations, answer questions, and discuss your needs and interests. In addition to the comprehensive display of products and services of interest to the scientific community, there will be giveaways, several drawings for prizes, and a free ACS souvenir for all visitors to the exposition.
Admission Requirements. Although admission to the exposition is complimentary, a badge is required to enter the exhibit hall. Badges will be mailed to all preregis-trants; on-site registrants may obtain a badge at the main registration area in the Washington Convention Center.
Exposition Workshops. A series of exposition workshops will be conducted in Washington and will cover a variety of topics. Attendance will be limited and restricted to workshop registrants (see pre-registration form on page 109). Workshops will be held Monday through Wednesday,
W A S H I N G T O N , O.C Aug. 24-26, in the Washington Convention Center. See pages 108 and 109 for a complete workshop schedule.
Commemorative Postal Cachet/Postal Substation. The 15th in a series of philatelic covers featuring ACS presidents will be available for sale at the Beckman Center for the History of Chemistry booth (758). Sponsored by the ACS Division of the History of Chemistry, this cachet will feature Edgar Fahs Smith, ACS president in 1895 and 1921-22. A temporary postal station will be available in the exposition area, and a special ACS postal cancellation commemorating the 204th national meeting will be available for use on the commemorative envelope. Mail orders for these envelopes will be accepted if postmarked by Aug. 13. Order forms may be obtained by sending a stamped, self-addressed envelope to John Sharkey, Chemistry Department, Pace University, Pace Plaza, New York, N.Y. 10038. Those who ordered an envelope from the San Francisco meeting will automatically receive a new order form.

EXPOSITION WORKSHOPS Because of space limitations, workshop attendance will be by registration only, even though they are being offered without charge by the sponsoring companies. Please use the preregistration form on page 109 to ensure space in the workshop(s) of your choice. Should you be able to register only on site, please check in with the sponsoring company at its booth to inquire about availability of your chosen workshop. Booth numbers are indicated after each exhibitor listing. Because of the timely and interesting topics of these workshops, they will nil up quickly—early registration is encouraged. All workshops will be held in the Washington Convention Center.

WEDNESDAY, AUG. 26
11. New Advances in the Estimation of LogP and Solvation-Free Energies
Sponsor: Molecular Simulations. Instructor: Mario Blanco. 10 AM to noon. Room 16.
A quantitative understanding of molecular solution properties is critically important to biochemistry, medicine, materials, the environmental sciences, and drug design. In the past, predictive models have been either too expensive to be of practical use (free energy pertubation theory) or not accurate enough. Polaris, a new method that includes all key energetic contributions of molecules in solution, will be presented. Results to within 0.15 LogP units and 1 kcal per mole in solvation-free energies are possible in minutes.
