Molybdenum

Molybdenum is a chemical element with symbol Mo and atomic number 42. The name is from Neo-Latin molybdenum, from Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. The mass number is 95.94, number of neutrons is 54, the electron configuration is [Kr]4d⁵5s¹. Molybdenum is used as glass furnace electrodes due to its high melting point. It is also used in the petroleum industry, to catalyze the removal of organic sulfur compounds in coal liquification and gas

You wake up in the morning and can practically smell that salt air. The ocean calls. You start to assemble your gear. You check and, yes, you did remember to clean your spinning reels. Then you spot those needle nose pliers you've been using to remove hooks. You forgot to clean the jaws and they've rusted shut forever. It's time to invest in some fishing pliers, but which pliers? Choosing fishing pliers isn't easy because, let's face it, there are so many excellent pliers on the market. There

School of Chemistry @ Pietermaritzburg University of KwaZulu Natal Chemistry 310 Substitution reaction of Molybdenum Hexacarbonyl: the use of infrared spectroscopy as a structural tool in metal carbonyl chemistry. Abstract The synthesis of isomer A and B of [Mo(CO)4(PPh3)2] were prepared from molybdenum hexacarbonyl, sodium borohydride and triphenylphosphine with a % yield of 79% and 8.5% respectively. Two isomer was identified using IR spectra and from isomer A four C≡O stretching

The existence of metal-like electronic conductivity of molybdenum (IV) oxide has formulated them as promising materials in energy related applications [8–10]. Graphene, which is the most recent material of the carbongroup, is considered as one of the greatest smart materials ofthe 21st century.[1] Graphene and

Recently semiconductor based photo-catalysis as a sort of Green technology which has attracted notable attraction among the researchers. This field has emerged as one of the most promising ways for photo conversion-related technologies by harvesting sun light in environment and energy fields. In general photocatalytic oxidation has been applied broadly in the process of removal of organic pollutants in water and air as a cost-effective and environmentally friendly technology, which could decompose

same time to keep the balance of two phases. There is usually at least 16% of chromium in austenitic stainless steel and at least 20% of nickel in duplex grade. (b) Molybdenum The role of molybdenum is supporting chromium and nickel to enhance the resistance of the local and other corrosions as pitting and crevice corrosion. Molybdenum is a ferrite stabilizer. The performance of mo can be three time when the chromium content is higher than 18%. (c)
