James T. Grady Award
Frank E. Carey
From atom smashers to Presidential gallstones, from space shots to polio vaccines: Thus does Frank E. Carey, recipient of the 1966 James T. Grady Award, suggest the range of topics he has covered as an Associated Press science writer. His excellent reporting of matters involving chemistry earned him the award, which was presented to him at the 151st ACS National Meeting by Dr. John H. Nair, chairman of the ACS Committee on Publication, Professional, and Member Relations. Mr. Carey, 56, was born and raised in Lowell, Mass. Manifesting early his desire to write, he contributed articles to a local paper while still in high school. He took the premedical curriculum at Holy Cross College, graduating cum laude in 1930. After teaching chemistry at Lowell High School, he joined the staff of the Lowell Sun in 1931, remaining with the paper as a general reporter until 1938. He then went to AP's Boston bureau. During his career Mr. Carey has taken part in the refinement that science writing has undergone. He contrasts his early article on the removal of a tooth from the local zoo's hippopotamus with his recent coverage of radioactive reindeer near the arctic circle. Controversies have evolved from the polite disagreements on the age of the earth to the potentially explosive subjects of fluoridation and pesticide residues. As an example of this refinement, Mr. Carey's first "science" story was about Shirley Temple's bad case of tonsilitis. He recalls that his story
had only a few words on tonsilitis; everyone was more interested how the child star felt. Now, Mr. Carey adds, when a famous person becomes ill, as did President Johnson with his gallstones, there is a "blow-by-blow dissertation on anatomy and surgery." He then covered his first ACS national meeting, crediting much of his success there to James T. Grady. Since then Mr. Carey has reported on more than a dozen ACS national meetings. Some stories are not as easy to get as those from ACS meetings. Mr. Carey kept a hard-to-get appointment with Dr. Albert Einstein in 1942 with the help of a truck driver in Princeton, N.J. Unable to get a cab to the famous scientist's house, Mr. Carey thumbed a ride in a dump truck, got his interview, and found that "the greats of science are not so rough." Mr. Carey was transferred in 1943 to AP's Washington bureau as a fulltime science writer, a post he still holds. His articles appear in 2600 papers here and abroad. After World War II, Mr. Carey attended Harvard University under a Nieman Fellowship for journalists. He concentrated on enlarging his scientific background; when Harvard did not offer the astronomy course he wanted, he had the "good fortune" to take it at Radcliffe instead. Mr. Carey's definitive reporting has led to several other awards: the Westinghouse-AAAS Award (1948); Christopher Literary Award (1952); American Heart Association (1956); and last year the Epilepsy Foundation Journalism Award.

Arthur C. Wahl
It's not very often that a Ph.D. candi date gets to do thesis work on the dis covery of a new element. But for Dr. Arthur C. Wahl, winner of the 1966 ACS Award for Nuclear Applications in Chemistry, the feat was but a pre lude to a career which contains many pioneering achievements. Dr. Wahl is Henry V. Fair Professor of Radiochemistry at Washington University in St. Louis, Mo., and director of the school's radiochemistry laboratory. It was as a graduate student at the University of California, Berkeley, that Dr. Wahl, working with Dr. Glenn T. Seaborg and the late Dr. Joseph W. Kennedy, played an important part in the discovery of plutonium. In this work, it was necessary to determine the half-life of plutonium from its ob served alpha activity without being able to measure directly the small amount of plutonium-239 present. This was accomplished by making an absolute beta count on a known amount of one of the precursors of plutonium (neptunium-239) and ob serving the alpha disintegration rate of the plutonium produced. But because the counting equip ment available at the time was rela tively primitive, Dr. Wahl had to work out an elaborate procedure for crosscalibrating three different beta count ing instruments of decreasing sensi tivity. This procedure for half-life determination was subsequently used in studies of other radioactive mate rials. It was not improved on until better counting equipment became available and more was known about decay schemes. Dr. Wahl later went on to conduct the first intensive radiochemical stud ies of plutonium. He also made a
similar study of neptunium. He was a coauthor of the first report describ ing the fissionability of plutonium-239. More recently, Dr. Wahl has switched his research emphasis from studies of heavy metals to fission proc esses, and to kinetics of electron trans fer exchange reactions. In the kinetics studies, he successfully used radioac tive tracers to study the exchange ki netics of reactions which other investi gators had regarded as immeasurably fast. In this work, Dr. Wahl employed "stand-in" carriers, along with novel, extremely rapid, mixing procedures. These studies have extended the knowledge of reaction kinetics to in clude rates not previously studied. Dr. Wahl is the senior editor and a contributor to the textbook, "Radioac tivity Applied to Chemistry." This text was one of the first on the subject, and is considered by many to have put the topic on a firm enough foundation for other workers to build on. Dr. Wahl is considered a quiet but warm person. His students rank him tops as a teacher and research adviser, and cite his ability to recognize ex actly how much direction and guid ance a research student needs. A native of Des Moines, Iowa, Dr. Wahl received his B.S. in chemistry at Iowa State College in 1939 and his Ph.D. in chemistry at Berkeley in 1942. The ACS Award for Nuclear Appli cations in Chemistry, consisting of $1000 and a certificate, was presented to Dr. Wahl at the 151st ACS Na tional Meeting in Pittsburgh by Dr. Haldon A. Leedy, president of Nu clear-Chicago Corp., which sponsors the award.

Dr. Richard H. Wilhelm, professor of chemical engineering and chairman of the department at Princeton University, has been given the ACS Award in Industrial and Engineering Chemistry, sponsored by Esso Research & Engineering. The honor was conferred last week at the ACS meeting in Pittsburgh by Dr. C. E. Starr, Jr., Esso v.p. Dr. Wilhelm has contributed greatly to an understanding of the behavior of packed columns, fluidization, and mixing of reactants. To his work in each of these areas he has brought the determination that the studies be transformed from the intuitiveness of an art to the logic of science. In bringing about this transformation, he has separated a complex system into its component parts for mathematical analysis and has recognized, adapted, and applied new techniques of analysis. In fluidization, Dr. Wilhelm has emphasized the importance of the difference between particulate and aggregative fluidization and has defined the conditions under which the two regimes are found. His findings in this area have been widely used in designing equipment for fluid-bed chemical reactors for pneumatic transport, for handling slurries, and for heat transfer by fluidized particles. Some 20 years ago, Dr. Wilhelm began studying packed-bed reactors. His goal was to define their behavior in precise quantitative terms. To achieve this goal, he devised experimental and analytical techniques for accumulating a detailed knowledge of local conditions and local processes taking place in a packed catalytic reactor. As a result of this and many of Dr. Wilhelm's previous contributions, designers are now able mathematically to de-
scribe more accurately the chemical kinetics, surface processes, various mass transfer processes, thermal exchanges, and momentum exchanges that occur simultaneously in a packedbed reactor. Dr. Wilhelm also developed techniques and methods of analysis for studying turbulent mixing down to the molecular scale on which reactions finally depend. For example, he devised light-scattering techniques for investigating fine-grained turbulence in liquids, and he developed an electrical conductivity probe for measuring liquid-phase concentration fluctuations. His work in this area is of basic importance in predicting the behavior of stirred reactors. In the February 1965 Fundamentals quarterly of Industrial h- Engineering Chemistry, he introduced the results of his latest work, a parametric pumping system for separating binary fluid mixtures (C&EN, Feb. 21, page 4 5 ) . In this system, separation is effected by pushing the fluid mixture back and forth through a column of adsoiptive particles in which an axial temperature gradient is imposed. Flow of the fluid mixture into and out of the columns containing the adsorbent is controlled by two pistons acting in tandem. This system, which could be used, for example, in changing the concentration of saline water, offers the advantage of continuous operation with a single fixed-bed adsorber. Dr. Wilhelm graduated from Columbia University with a B.S. degree in 1931 and was later awarded a Ch.E. (1932) and a Ph.D. (1935) there. His entire professional career has been at Princeton, starting with an instructorship in 1934.

Or—KELZ3N* is a thickener that flows when you agitate it, and thickens when you stop. Changes the viscosity of your product instantly. Picture the possibilities of this unusual flexibility. Without shear, KELZ3N solutions have constant viscosity—over essentially the entire pH range. They're also compatible with high concentrations of salts, acids and alkalies. They remain stable over a wide temperature range for long periods.
