The new carboxylato-dinitrosyl-molybdenum complexes o f the formula: [M o(NO )2( 0 2CMe)2] • MeOH, N a2[M o(NO)2( 0 2CMe)4] and M o(N O )2( 0 2CPh)2 have been synthesized. Their structure was resolved on the basis o f spectroscopic investigations ('H N M R , IR, U V -V IS ). Catalytic activity o f these complexes in olefin metathesis reaction was also examined. The electronic structure o f dini...

Mycobacterium vaccae 10 growing in methanol medium synthesizes two inducible alternative NAD(+)-dependent formate dehydrogenases (FDH). In the presence of molybdenum, the dominating form of the enzyme is FDHI with Mr 440 kDa and Km 0.32 mM for sodium formate. FDHI reduced ferricyanide as well as NAD+, and it was reversibly inactivated by formate. NAD+ stabilized FDHI against this inactivation. ...

Transition-metal dichalcogenides like molybdenum disulphide have attracted great interest as two-dimensional materials beyond graphene due to their unique electronic and optical properties. Solution-phase processes can be a viable method for producing printable single-layer chalcogenides. Molybdenum disulphide can be exfoliated into monolayer flakes using organolithium reduction chemistry; unfo...

Khatunabad area is situated geologically in UrmiehDokhtar magmatic belt in NW of Iran. In this research, studied area has been investigated in order to recognize the potential copper and molybdenum-bearing target areas. The survey layers include the lithologic units, alteration, geochemical result, tectonics and copper and molybdenum occurrence. As an accurate decision can have a considerable e...

PNH is a clonal hematopoietic stem cell disease associated with a complementdependent hemolytic anemia. The disease manifests after the expansion of a multipotent hematopoietic stem cell that acquires a mutation of the PIGA gene. The PIGA gene product is required for the biosynthesis of glycophosphatidylinositol anchors, a glycolipid moiety that attaches dozens of proteins to the plasma membran...

The iron-molybdenum cofactor, or the Mcluster, serves as the active site of molybdenum nitrogenase. Arguably one of the most complex metal cofactors in biological systems, the M-cluster is assembled through the formation of an 8Fe core prior to the insertion of Mo and homocitrate into this core. Here, we review the recent progress in the research area of M-cluster assembly, with an emphasis on ...

The intrinsic impurity content of molybdenum and carbon was measured in the Alcator C-Mod Tokamak using low resolution, multilayer mirror (MLM) spectroscopy (∆λ ~ 1-10 Å). Molybdenum was the dominant high-Z impurity and originated from the molybdenum armor tiles covering all of C-Mod's plasma facing surfaces (including the inner column, the poloidal divertor plates, and the ICRF limiter). Despi...
