The Marathon began on April 12, 1980, when Fox dipped his right leg in the Atlantic Ocean near St. John's, Newfoundland, and filled two large bottles with ocean water. He intended to keep one as a souvenir and pour the other into the Pacific Ocean upon completing his journey at Victoria, British Columbia.is right leg was amputated in 1977 after he was diagnosed with osteosarcoma, though he continued to run using an artificial leg. He also played wheelchair basketball in Vancouver, winning three national championships. In 1980, he began the Marathon of Hope, a cross-country run to raise money for cancer research.
Molybdenum-based alloys have a unique combination of properties, including high strength at elevated temperatures, high thermal and electrical conductivity, and low thermal expansion. Molybdenum metal and its alloys are the first choice in many demanding specialized applications.
When alloyed with nickel, molybdenum forms heat and corrosion resistant materials used in the chemical industry. Molybdenum disulphide (MoS 2), one of molybdenum's compounds, is used as a high temperature lubricant. Molybdenum trioxide (MoO 3), another molybdenum compound, is used to adhere enamels to metals.ome electrical filaments are also made from molybdenum. The metal is used to make some missile and aircraft parts and is used in the nuclear power industry. Molybdenum is also used as a catalyst in the refining of petroleum.
