molybdenum
The effect of ultrasound irradiation on molybdenum trioxide has been investigated.
      
The physicochemical changes of MoO3 due to ultrasound irradiation have been attributed to the sonochemical cavity collapse onto the molybdenum trioxide particles.
      
Molybdenum isotope composition from Yangtze block continental margin and its indication to organic burial rate
      
Molybdenum, at a concentration lower than half the concentration of tungsten, as well as iron, selenium, and pterin at concentrations 2.5 times higher than that of tungsten, had no effect on tungsten determination by this method.
      
During the formation and ripening of beans in yellow lupine, their intactness may be increased by treatment of the plants with the microelement molybdenum or the growth factor 24-epibrassinolide.
      
Studies of nitrate reductase from the mycelium of Fusarium oxysporum 11dn1, grown under aerobic and anaerobic conditions, showed that this enzyme belongs to molybdenum-containing nitrate reductases.
      
It was shown that the strain possessed molybdenum-dependent nitrogenase activity, and its nitrogenase system was sensitive to oxygen and fixed nitrogen in the medium.
      
Tungsten was previously considered only as an antagonist of molybdenum, because the replacement of molybdenum by tungsten (due to their chemical similarity) leads to inactivation of molybdenum containing enzymes (Mo-enzymes).
      
In addition to the "true W-enzymes" in which tungsten cannot be replaced by molybdenum, recently some enzymes have been isolated which can use either molybdenum or tungsten in the catalytic process.
      
Characterization of Molybdenum-Free Nitrate Reductase from Haloalkalophilic Bacterium Halomonas sp.
      
The isolated enzyme belongs to a novel family of molybdenum-free nitrate reductases.
      
The salt tolerant Rhodotorula glutinis yeast strain grew in medium containing nitrate, 1 mM tungsten, and trace amounts of molybdenum (as impurities from the reagents used).
      
The isolated nitrate reductase is a molybdenum-containing homodimer with molecular mass of 130 kD, containing 0.177 mol of Mo per mol of the enzyme.
      
Molybdenum Sulfide Nanoparticles as New-Type Additives to Hydrocarbon Lubricants
      
In accordance with the phase diagram, the ternary system of the alloy consists of an a-solid molybdenum-nickel solution, which is in equilibrium with a β-solid rhenium-nickel solution and a Ni4Mo intermetallic compound.
      
On heating the alloy in a temperature range of 750-960 K, the intermetallic compound transforms into the α-solid molybdenum-nickel solution with the absorption of heat, while the ordered structure transforms into a disordered one.
      
Calculation of the Electrical Conductivity of Liquid Aluminum, Copper, and Molybdenum
      
The electrical conductivity of aluminum, copper, and molybdenum is calculated using the Ziman theory of liquid metals and modified Ashcroft potential.
      
The behavior of the acoustic properties and acoustic-emission activity of 08Kh14AN4MDB (chrome-nitrogen-nickel-molybdenum-copper-niobium) structural steel is investigated in the process of annealing and after quenching.
      
Chromaticity characteristics of binary and ternary molybdenum(vi) complexes with o,o'-Dihydroxyazo and heterocyclic azo compound
