Titanium is one of the most utilized metals for orthopedic implants. This element has excellent mechanical and biological properties. As a strategy to develop new system alloys that do not cause health problems patient, such as Ti-6Al-4V alloy, group been designed meet these expectations. Molybdenum, when associated with titanium, reduces transition temperature from α β phase. Zirconium increas...

A speciation scheme of trace molybdenum was proposed for river water based on size fractionation by filtration and ultrafiltration and the catalytic spectrophotometric determination of the reactive molybdenum concentration (CR). The total concentration (CT) of molybdenum was determined by the same method after acid decomposition to obtain the concentration (CT - CR) of unreactive molybdenum. Mo...

one of the important methods of plant propagation in large scale so as genetic manipulation and artificial seed production is somatic embryogenesis technique. the obtained results from this methods related to different factors including condition of culture medium. therefore, the aim of this study conduction were determining the role of molybdenum during carrot petiole somatic embryogenesis. at...

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 ...

Titanium (Ti) is employed as a biomaterial because of its superior biocompatibility and favorable mechanical properties that can be changed with the addition alloying elements, such zirconium molybdenum. Silver an element recognized for antibacterial action, which improve strength decrease Young’s modulus Ti. This work studies effect silver (1 3 wt%) on crystalline structure, microstructure, Vi...

Wire + arc additive manufacturing is an welding process that uses non-consumable tungsten electrodes to produce the weld. The material used in this study a titanium, carbon, zirconium, and molybdenum alloy physically chemically stable has good performance for use as high-temperature heating element. In study, experiments are designed based on central composite design, single-layer wire performe...

Cr-Co-Mo (ASTM F75) alloy has been used in the medical environment, but its use as a rigid barrier membrane for supporting bone augmentation therapies has not been extensively investigated. In the present study, Cr-Co-Mo membranes of different heights were placed in New Zealand white, male rabbit tibiae to assess the quality and volume of new bone formation, without the use of additional factor...

Background: With the spread of nanotechnology, various nanoparticles with new and emerging properties have been produced and the potential toxic effects of the majority of these particles remains still unknown. The present study was conducted to determine the toxicity of Molybdenum Trioxide nanoparticles in blood and body tissues of male Wistar rats. Materials and Methods: Thirty Wistar rats w...

The influence of dietary molybdenum on esophageal carcinogenesis induced by N-methyl-N-benzylnitrosamine (2.5 mg per kg of body weight once a week for 20 wk s.c.) was studied in male F344 rats. The tumor incidence and tumor development in the esophagus were significantly lower in the rats in the high-molybdenum (2 ppm) diet group than in the rats in the low-molybdenum (0.032 ppm) diet group; i....

In this work we establish an approach to model miscibility gaps of alloys using statistical physics, lattice dynamics from first-principles calculations. We carefully calculate the entropy include all processes introducing disorder system, i.e., combining electronic, phononic, and configuration entropies. Furthermore present our algorithm for generating Special Quasirandom Structures (SQS). gap...
