Transmission electron microscopy study of low Mo-content Bi-Mo-O phases

Electron Microscopy of the Mo-fe Protein from Azotobacter Nitrogenase

Biological N2 fixation, the reduction of N2 to NH 3 , is catalyzed by the enzyme nitrogenase . Fractionation studies of nitrogenases from a variety of organisms have shown that all are composed of two similar proteins, one contains Mo and Fe and is called the Mo-Fe protein and the other contains only Fe and is called the Fe protein . Recently homogeneous preparations of these proteins from Azot...

Transmission Electron Microscopy Investigations of Thin Mo and Pd Films Grown on SrTiO 3 Substrates

Tuning the electronic structure of Mo-Mo quadruple bonds by N for O for S substitution.

A series of quadruply bonded dimolybdenum compounds of form Mo(2)(EE'CC≡CPh)(4) (EE' = {NPh}(2), Mo(2)NN; {NPh}O, Mo(2)NO;{NPh}S, Mo(2)NS; OO, Mo(2)OO) have been synthesised by ligand exchange reactions of Mo(2)(O(2)CCH(3))(4) with the acid or alkali metal salt of {PhC≡CCEE'}(-). The compounds Mo(2)NO, Mo(2)NS and Mo(2)OO were structurally characterised by single crystal X-ray crystallography. ...

Building Topic Specific Language Mo Competitive Mo

The ability to build topic specific language models, rapidly and with minimal human effort, is a critical need for fast deployment and portability of ASR across different domains. The World Wide Web (WWW) promises to be an excellent textual data resource for creating topic specific language models. In this paper we describe an iterative web crawling approach which uses a competitive set of adap...

Mesostructural Bi-Mo-O catalyst: correct structure leading to high performance

Structure-activity relationship has been one of the main topics of research on catalysts all the time. Component and structure are the two moieties governing the performance of solid materials as catalysts. Multicomponent bismuth molybdates are well known catalysts for propene oxidation but pure crystalline phases of bismuth molybdate are inactive for the reaction. We have designed mesostructur...
