This paper reports for the first time X-ray crystal structures for a parent heteropoly complex and for its heteropoly blue reduction product. The potassium salt of the former complex, α-[CoIIW12O40]6-, is ordered in space group P6,22; and the potassium salt of its two-electron heteropoly blue reduction product, α-[CoI…

We study transitions to periodic structures in diblock copolymer melts including self-consistently the concentration fluctuations, and expanding the density in multiple harmonics. The fluctuations induce a shift in the maximum scattering wave vector in the isotropic state which suggests that the chains stretch near th…

Vilsmeier reactions between nickel(II) or copper(II) porphyrins or chlorins and 3-(dimethylamino)- acrolein/phosphoryl chloride (3-DMA/POCI3) are described. For example, copper(II) octaethylporphyrin 5 affords the meso-(2-formylvinyl) derivative 7, which cyclizes in strong acid to give the benzochlorin 10. Treatment o…

Nonstationary and stationary concentration profiles of vacancies in a grain boundary are calculated for the case of electromigration and various conditions of vacancy formation and annihilation. If supersaturation of vacancies is assumed for void formation, current densities necessary for voiding have to be larger tha…

In the anaerobic, thermophilic, cellulolytic bacterium Clostridium thermocellum, efficient solubilization of the insoluble cellulose substrate is accomplished largely through the action of a cellulose-binding multienzyme complex, the cellulosome. A major cellobiohydrolase activity from the cellulosome has been traced…

Previous observations suggested that pNcollagen III, the partially processed form of type III procollagen, coats fibrils of collagen I and thereby helps regulate the diameter of fibrils formed by collagen I. The previous observations, however, did not exclude the possibility that pNcollagen III was deposited on prefor…

Precursors for the preparation of carbon nitride were selected from a number of relatively high nitrogen content organic materials. The precursors were pyrolyzed in a closed system at 700°C under 225 MPa. The resulting residues showed little nitrogen loss, but were amorphous with relatively low densities. Raman spectr…
