The paper deals with the thermal properties of complex compounds of the general formula CuL2(NCX)2 (whereL=bipy or phen,X=S or Se). The phenanthroline complexes exhibit a higher thermal stability than those with bipyridine. For the latter complexes thermal decomposition begins with the release of bipyridine molecules, while for the phenanthroline complexes redox reactions of pseudohalogenide ligands with Cu(II) take place. The redox reactions start at a lower temperature for the selenocyanate complexes than for the thiocyanate complexes.
Zusammenfassung Vorliegende Arbeit behandelt die thermischen Eigenschaften von Komplexverbindungen der allgemeinen Formel CuL2(NCX)2 (mitL=Bipyridin oder Phenanthrolin undX=S oder Se). Die Phenanthrolinkomplexe zeigen eine grössere thermische Stabilität als die Bipyridinkomplexe. Die thermiscne Zersetzung letzterer beginnt mit der Abgabe von Bipyridinmolekülen, während bei den Phenanthrolinkomplexen Redoxreaktionen von Pseudohalogenidliganden·mit Cu(II) stattfinden. Diese Redoxreaktionen beginnen bei den Selenozyanatkomplexen bei niedrigeren Temperaturen als bei den Thiozyanatkomplexen.

In this paper, we study weighted inequalities for multilinear fractional maximal operators and fractional integrals. We prove sharp weighted Lebesgue space estimates for both operators when the vector of weights belongs to . In addition we prove sharp two weight mixed estimates for multilinear operators in the spirit of the linear estimates given in 3 . 相似文献

In drug development research, the elucidation and understanding of the interactions between physiologically active substances and proteins that numerous genes produce is important. Currently, most commercially available drugs and physiologically active substances have been brought to market without knowledge of factors interacting with the drugs and the substances. Affinity purification is a useful and powerful technique employed to understand factors that are targeted by drugs and physiologically active substances. However, use of conventional matrices for affinity chromatography often causes a decrease in efficiency of affinity purification and, as a result, more practical matrices for affinity purification have been developed for application in drug discovery research. In this paper, we describe the development of high‐performance affinity beads (SG beads and FG beads) that enable one‐step affinity purification of drug targets and the elucidation of the mechanism of the action of the drugs. We also describe a chemical screening system using our affinity beads. We hope that utilization of the affinity beads will contribute to the progress of research in chemical biology. © 2009 The Japan Chemical Journal Forum and Wiley Periodicals, Inc.

We give several characterizations multiparameter Ap(Td) in terms of strong maximal functions, rectangular conjugate functions, and rectangular partial sums. We also define a way to enumerate Zd that corresponds to rectangles. We then use these enumerations to give another characterization of rectangular Ap(Td) in terms of trigonometric Schauder bases. Finally, we present some applications to principle shift invariant spaces and Gabor systems. 相似文献

Elucidation of the hydrodesulfurization (HDS) mechanism on molybdenum‐based catalysts using radioisotope tracer methods and reaction kinetics is reviewed. Firstly, to investigate the sulfidation state in Mo/Al2O3 and Co–Mo/Al2O3 catalysts, presulfiding of these catalysts has been performed using a 35S pulse tracer method. Secondly, HDS of radioactive 35S‐labeled dibenzothiophene was carried out over a series of sulfided molybdena–alumina catalysts and cobalt‐promoted molybdena–alumina catalysts in a pressurized flow reactor to estimate the behavior of sulfur on the working catalysts. Finally, sulfur exchange of a 35S‐labeled catalyst with hydrogen sulfide was performed to estimate the relationship between the amount of labile sulfur and catalytically active sites. 相似文献
