the voltammetric characteristics of mo (vi) oxinate at the mercury electrode, in the presence of tri-butylammonium perchlorate (tri-bap) and piperidinium perchlorate (pp) + piperidine (p) as  two different types supporting electrolytes, have been studied in chloroform. with the both supporting electrolytes a two electron irreversible process for the reduction  of mo (vi) oxinate was observed. p...

The preliminary findings that molybdenlum, in minute amounts, improved the growth of barley plants in a culture solution supplied with ammonium salts as the sole source of nitrogen (1), and that a group of seven heavy metals including molybdenum increased the growth of lettuce and asparagus (2), supported the view that the list of essential elements for higher plants is incomplete and suggested...

Unlike molybdenum-oxo corroles, molybdenum-dichlorido Viking helmet corroles are noninnocent, with substantial corrole radical character.

The miscible displacement process appears to be an increasingly feasible method for the extraction of oil from depleted reservoirs. How‌ever, there is a lack of fundamental understanding of how fracture geometrical characteristics impact the oil recovery efficiency in this type of enhanced oil recovery technique. In this work, a series of experimental tests were conducted whereby the n-Hept...

The molybdenum enzymes sulfite oxidase and xanthine dehydrogenase have been investigated by fluorescence-detected EXAFS using synchrotron radiation, and the results have been interpreted with improved EXAFS analysis procedures. A new treatment of EXAFS amplitudes has been developed which allows the extraction of meaningful Debye-Waller factors using experimentally derived functions. A search pr...

Molybdenum is an essential element in plants and animals as a cofactor for enzymes. Molybdenum trioxide is used in metallurgical processes, in cosmetics as a pigment, and in contact lens solution, yet limited information is available on molybdenum genotoxicity. In the present study the micronucleus (MN) assay in human lymphocytes and mouse bone marrow and the dominant lethal assay in mice were ...

In this study, a new recoverable catalyst for the epoxidation of olefins was developed using a layered polysiloxane as a support for immobilizing  (salen) molybdenum(VI) complex by electrostatic interaction between the surface of the solid support and the electrically charged molybdenum complex. Characterization of the heterogeneous catalyst by Fourier transform infrared, XRD,1H NMR,...
