which make up the Catalysis Society, it gives details of forthcoming meetings, the award of prizes (see next item), activities of members etc. The latest issue (21, No. 2, 1987) contains a reuort of the Tenth North American Meeting of the Society which was held in May of this year, as well as forthcoming preliminary details of meetings. (See Calendar for the 1989 meeting.) Membership of the Catalysis Society, and hence receipt of the Newsletter, is automatic for those affiliated with one of the local clubs or societies. Further information, including the contact address of your local society, can be obtained by writing to Dr. R.D. Gonzalez, Secretary, Catalysis Society, University of Illinois at Chicago, Dept. of ;p;;n8; Engineering, Box 4358, Chicago,

Suspected Fibrogenic Activity of Dusts from Zeolites article Russian A recent by A. Fomina, S. Domnin, T. Gerasimenko, N. Sukhanova, G. Belobragina, E. Kotov, L. Izmailova, and I. Yatovt in Gig. Tr. Prof. Zabol., Vol. 9, page 17, 1986, reports that Y type zeolites and mordenites show positive tests for fibrogenic activity. This is the first such report of this type of activity. Until all the evidence is in, appropriate respirator equipment may be advised. Fibrogenicity of calcined (45O'C) Type Y and mordenite zeolite dusts was determined on the basis of the accumulation of lipids and hydroxyproline in the lungs of rats. CaY and H-mordenite gave the least fibrogenicity and HY and LaY the greatest. The fibrogenicity correlates with greater acidity of the Y type zeolite. However, the H-mordenite proved to be more cytotoxic than HY.

Synthesis of Amino Compounds In a Japanese patent (J6 2039-548-A) to Mitsui Toatsu Chem., Inc., amino compounds were prepared in one step in the gas phase by reaction of various organic compounds with HNO in a reducing athydrogenation mosphere over se?ected included catalysts. Aromatics cited benzene, napthalene and pyridine in dilute of fuming HN03 in the presence of reducin8 catalysts (Pd, Pt, Ni, etc.) at 200-350 C in H2.

Catalysis Society Awards Including in the Catalysis Society Newsletter are details of awards which have been made by some of the participants clubs and societies. The Catalysis Society of Metropolitan New York have presented their 1987 Award for Excellence in Catalysis to Drs. G.L. Goeke, R.J. Jorgensen, F.J. Karol, I.J. Levine and B.E. Wagner for their development and commercializationof the Unipol process for the production of high-density and linear, low-density polyethylenes. This group of Union Carbide researchers developed the high-activity catalysts for this unique and versatile fluid bed process. The Philadelphia Catalysis Club award for 1987 has been presented to Dr. James E. Lyons, Senior Staff Scientist and Group Leader at the Sun Company. Dr. Lyons is the author of over 60 patents and 36 publications in the area of organometallic chemistry, and molecular catalysis and has lectured widely on his research in oxidation, hydrogenation, isomerization and carbonylation of organic substrates to produce fuels, lubricants and chemical products. The Pittsburgh/Cleveland Catalysis Society Award in fundamental and applied catalysis was presented post-humously to Professor Paul Biloen, formerly of the University of Pittsburgh Department of Chemical and Petroleum Engineering. Prof. Biloens most recent and widely respected research work was in the develisotopic opment of techniques for switching in the study of surface reactions. His untimely death occurred on October 28, 1986.

Opportunities for Innovation in the Application of Catalysis One of the additions to the latest list of forthcoming meetings is one with the above title which is to be held in the Hall of Residence of Queen Mary College, London, on 6th and 7th January, 1988. This is a joint meeting between the Royal Society of Chemistry and the Applied Catalysis Group of the Institution of Engineers. The intention of the meeting is to focus on how catalysis can development, open up new areas for stressing the interaction between the basic science and engineering. Topics which will be covered are energy conversion, effluent treatment (particularly
