Part I deals with the structure determination of five organic compounds by X-ray diffraction methods: the diacetate of the sesquiterpene voleneol, which in spite of having five chiral centers, was isolated from a plant as the racemate; two 1,4-dithiin 1,1,4,4-tetroxides, one an herbicide and the other a microbiocide; bouvardin, a bicyclic hexapeptide with anti-tumor activity; and a tripeptide that is an intermediate in a synthesis of the anti-tumor agent deoxybouvardin and which contains a novel hydrogen bond. Part II details efforts to synthesize deoxybouvardin. Compounds synthesized include the corresponding monocyclic hexapeptide (which shows no anti-tumor activity) and various precursors to the 14-membered ring of deoxybouvardin.

In the production of iron chromium honeycombs, iron oxide and chromium oxide mixtures are reduced by hydrogen at elevated temperatures to produce a metallic alloy. The complete reduction of the iron oxide occurs prior to the reduction of the chromium oxide. The reduction of the chromium oxide particles within the iron matrix is affected by factors that include the diffusion of the reduced chromium away from the chromium oxide particle into the iron matrix, the diffusion of the gaseous reactants and products to and from the chromium oxide particles, and the porosity of the iron matrix, which changes as a result of sintering. The type of heat-treatment used, (isothermal or non-isothermal, i.e., holding at a specific temperature versus using a steadily increasing temperature) plays a vital role in how these factors will affect chromium oxide reduction. Experimental data were used in conjunction with sintering and dissolution models to obtain an understanding of the environment in which the chromium oxide particles reduce as a function of heat-treatment. This understanding will assist in the development of more effective processing steps for the reduction of metallic honeycombs from oxide mixtures.
