Background: Molybden, as a vital and essential micronutrient is directly involved in the metabolism of other elements including carbon, sulfur, and nitrogen. Molybdenum alone is not biologically active unless it binds to specific cofactors. Except for the bacterial nitrogenase, which contains molybdenum-Iron complex, molybdenum cofactor (Moco) is considered as the bioactive component placed in ...

This article aims in exploring the dry sliding wear performances on aluminum (AA7075) metal matrix composites reinforced with molybdenum disulphide which is a solid lubricant using response surface methodology (RSM). Specific Wear Rate (SWR) for AA7075 pure alloy, AA7075+2wt% and AA7075+4wt% were measured according to ASTM G99 standards pin-on-disc apparatus. Design of experiments was selected ...

In this study, we systematically examined the influence mechanisms of introduced cobalt coated alumina (Co-coated Al2O3) particles on microstructure and properties cobalt-chromium-molybdenum (CoCrMo) alloy printed by Laser Powder Bed Fusion (LPBF). The Co-coated Al2O3 composite powders with different density coating were prepared varying load from 1 g/150 mL to 2 during electroless plating proc...

Due to its high thermal conductivity and favorable machinability, molybdenum–rhenium (Mo–Re) alloys have huge prospects in the field of high-temperature heat pipes. However, weldability Mo–Re has not yet been systematically investigated. Based on an orthogonal test, influence law single-mode fiber laser welding parameters weld profile mechanical properties joints was studied. Furthermore, exist...

the reduction mechanism of molybdenum-methyl thymol blue (mtb)-chlorate system has been investigated in water on a mercury electrode. as this system is very sensitive for ultratrace determination of molybdenum, the actual mechanism involved was studied. electrochemical techniques, including dc tast polarography and cyclic voltammetry were employed. it is shown that, the cathodic wave of molybde...

Selenium and molybdenum are essential trace elements. Considering the characteristics of selenium and molybdenum, our research had the following purposes for both elements: Considering Se the uptake of selenium was investigatein maize and sunflower seedling, moreover the different effect of two selenium species (selenite and selenite) for the examined plants (a monocotyledon (maize, Zea mays L....

A molybdenum cofactor which is capable of reconstituting demolybdosulfite oxidase purified from livers of tungstentreated rats has been identified in rat liver and various organisms. Reconstitution with the rat liver cofactor is directly proportional to cofactor and demolybdoenzyme concentrations and proceeds most efficiently in 0.01 M potassium phosphate buffer, pH 7.4. The activation process ...
