th Annual Summer
"Surface Characterization of Catalytic and Electronic Materials" is the subject of the 1985 Summer Symposium of the Division of Analytical Chemistry of the ACS. The symposium will be held June 18-20,1985, at Clarkson University in Potsdam, N.Y. The general chairman is Petr Zuman of Clarkson University, and the program chairman is Nick Winograd of Pennsylvania State·University. The symposium is sponsored by the ACS Division of Analytical Chemistry and ANALYTICAL C H E M I S T R Y .

Emulsion Problems Emulsions are finely dispersed droplets of one immiscible liquid in another. They pose a problem when they are formed during liquid liquid extractions. While centrifugation is often used to break emulsions, it is tedious and time consuming. There are ways ίο break emulsions.

evaluated values for the absolute po tential of the standard hydrogen elec trode in water and in a few other protic solvents. Comments on these recommenda tions are welcome and should be sent by August 1985 to the Secretary of the IUPAC Commission on Electrochem istry: S. Trasatti, Dipartimento di Chimica Fisica ed Elettrochimica, Via Venezian 21,1-20133 Milano, Italy. Those interested in making comments can obtain a copy of the document from the American Chemical Society, P.O. Box 3330, Columbus, Ohio 43210.
A nomenclature document on the absolute electrode potential has been prepared by IUPAC. The document begins with illustrations of the most widespread misunderstandings in the literature about the physical meaning of the term. The correct expression for this quantity is then derived by a ther modynamic analysis of the compo nents of the emf of an electrochemical cell. It is shown that, in principle, three reference levels can be chosen to measure an absolute value of the elec trode potential. Only one of these pos sesses all the requisites for a meaning ful comparison on a common energy scale between electrochemical and physical parameters. To allow such a comparison, the adoption of a correct scale for absolute electrode potentials is a prerequisite. The document ends with recommendations of critically

prize of $1000, a silver medal, and a citation are included in the award, which Hansch will receive at the 1985 Optical Society of America annual meeting, to be held Oct. 15-19 in Washington, D.C. Hânsch has been named to this award for his "discoveries of powerful techniques for high-resolution laser spectroscopy, and their application to fundamental problems of physics, particularly through precision measurements on atomic hydrogen." These techniques include the first narrowline tunable dye laser and the saturation, polarization, and polinex methods for eliminating Doppler broadening.

INTERFERENCES IN FURNACE ATOMIC ABSORPTION A Thing of the P a s t . . .
Allied Analytical Systems offers an approach to furnace atomic absorption that takes the worry out of furnace interferences. Our new system is based on the following: • The NEWIL755CTF™ Controlled-Temperature Furnace Atomizer with the Delayed Atomization Cuvette (DAC) which reduces vapor phase interferences by delaying atomization and causing atoms to be released into a hotter temperature environment. • The ILFAS7"/4C®II autosampler,a flame/furnace aerosol sampling system that not only automates sample introduction, but actually reduces solid phase interferences by eliminating the drying step associated with conventional autosamplers. • The SMITH-HIEFTJE System. A surprisingly simple but effective background correction system for correcting broadband and structured background over the entire wavelength range of atomic absorption. • Video graphics for visualization of uncorrected and background corrected signals.

News sandstone aquifer near Zurich. Fewer than 1000 krypton-81 atoms were isolated from the groundwater samples. According to Bernard Lehman, a collaborating geochemist at the University of Bern, this first test proved that counting the small numbers of krypton-81 atoms necessary to make an estimate of the age of water could actually be done. Among the applications of this method, Lehman says, could be improved siting of locations for the disposal of radioactive wastes.
NBS Budget for FY 1986 A total of $120 million is allotted for the National Bureau of Standards in the fiscal year 1986 budget proposal sent by the president to Congress. This budget request is $4 million less than the bureau's fiscal year 1985 appropriation of $124 million. Included are program increases totaling $16.4 million and cost-of-living and other built-in changes of $4.9 million. Proposed program increases are process and quality control measurements ($1.9 million), biotechnology ($3 million), advanced ceramics ($3.5 million), and cold neutron source ($8 million). The proposed budget also includes program reductions of $16.5 million and decreases of $8.8 million attributable to the Deficit Reduction Program. Proposed program reductions are building research ($3.1 million), computer sciences and technology ($5 million), fire research ($5.1 million), and equipment replacement ($3.3 million). Hearings on this budget proposal began the first week in March.
