Publication number: 20120094124Abstract: Single crystal MoO3 nanowires were produced using an electrospinning technique. High resolution transmission electron microscopy (HRTEM) revealed that the 1-D nanostructures are from 10-20 nm in diameter, on the order of 1-2 ?m in length, and have the orthorhombic MoO3 structure. The structure, crystallinity, and sensoric character of these electrostatically processed nanowires are discussed. It has been demonstrated that the non-woven-network of MoO3 nanowires exhibits higher sensitivity and an n-type response to NH3 as compared to the response of a sol-gel based sensor.Type: ApplicationFiled: June 9, 2011Publication date: April 19, 2012Inventors: Pelagia-Irene Gouma, Aisha Suzette Haynes, Krithika Kalyanasundaram

Patent number: 8137654Abstract: Provided is a roasting method capable of reducing both C and S components in minerals down to 0.5% or less, respectively, and securing a yield ratio of 90% or more for the Mo component. In a rotary kiln 7, a V, Mo and Ni containing material containing C and S components is subjected to oxidizing roasting to remove the C and S components from the material before reducing the material by means of a reducing agent in order to recover valuable metals composed of V, Mo and Ni. The rotary kiln is equipped with a burner 11 disposed on a material charge side 8a of the roasting furnace 8 to which the material is charged. In the roasting furnace, a direction along which the material moves and a flow of oxygen-containing gas introduced into the roasting furnace 8 are set to be parallel with each other.Type: GrantFiled: February 21, 2006Date of Patent: March 20, 2012Assignees: JFE Material Co., Ltd., Sumitomo Heavy Industries, Ltd.Inventors: Kenji Takahashi, Hiroichi Sugimori, Nobuo Ehara
