• Top seeding melt texture growth of NdBaCuO pellets in air

  Most of NdBaCuO synthesis were realized under oxygen controlled melt growth (OCMG) which allows to avoid the solid solution formation. However, for industrial applications air synthesis is preferable due to its simplicity and its cost. In this work, different seeds and thermal cycles have been investigated in order to optimize the nucleation conditions for the obtention of a single domain. Several criteria have been defined for the choice of the seed. The solid solution Nd_{1+xBa2−xCu3Oy formed in these air synthesised samples appears in the range of x = 0.10 to 0.15, corresponding to between 60 K and 80 K. The nominal composition and the synthesis conditions (substrate, thermal treatments.) have to be accurately defined in order to avoid neodymium-rich solid solution formation.}

  大部分NdBaCuO的合成是在氧控制熔融生长（OCMG）条件下实现的，这样可以避免固溶体的形成。然而，由于其简单性和成本优势，在工业应用中空气合成更受欢迎。在这项工作中，我们研究了不同的籽晶和热循环过程，以优化成核条件，从而获得单畴结构。我们为选择籽晶制定了几个标准。在这些空气合成样品中形成的固溶体Nd\(_1+x\)Ba\(_2-x\)Cu\(_3\)O\(_y\)，其\(x\)值在0.10到0.15之间，对应的转变温度为60K到80K。为避免富钕固溶体的形成，必须准确地定义标称组成和合成条件（衬底、热处理等）。

  facile method for the synthesis of meta-substituted arylamines from acyclic precursors was developed. This method is based on three-component cyclo-condensation/aromatization of in situ generated imines of acetone with 1,3-diketones either under conventional heating or under microwave irradiation. The utility of this methodology is illustrated by the possibility of a gram scale synthesis of various anilines

  A method for manufacturing tris(β-diketonato)iridium by reacting β-diketone with an iridium compound, in which an activation treatment including (a) an alkali treatment and (b) an acid treatment described below is applied to the iridium compound to activate the iridium compound, and to subsequently react the β-diketone, (a) an alkali treatment: a treatment of adding alkali to a solution of the iridium compound to raise pH of the solution to a more alkaline side than that before the alkali addition and to not less than 10, and (b) an acid treatment: a treatment of adding acid to the solution subjected to the alkali treatment to lower pH of the solution to a more acidic side than that before the acid addition and to make the pH difference between solutions before and after the acid addition be not less than 0.1 and not more than 10. The present invention allows manufacture of tris(β-diketonato)iridium utilizing a wide variety of β-diketones.
