  1. 6. Development of Techniques to Produce Nickel Coated Composite Materials as well as Hollow Nickel Fibres and Kinetic Study of the Process Involved

    Författare :Fan Li; Sichen Du; Ioannis Arvanitidis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nickel; Chemical plating; Kinetics; Model; Hollow nickel fibres; Thermal decomposition; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The present thesis was mainly to study the preparation of nickel composite materials by chemical plating process. Nickel coated boron nitride particles, nickel coated spherical silica particles and nickel viscose composite fibres were prepared. Both experiment and model development were carried out to study the kinetics of the processes. LÄS MER

  5. 9. Structural aspecs on compounds in the CsI-(Cd/Hg)I2 system

    Författare :Rune Sjövall; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tetrahedral distorsion; thermal decomposition; Biltz concept; structural relationships; hydrate; iodine; mercury; caesium; cadmium; coordination number modelling; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Structural investigations of compounds in the CsI-(Cd/Hg)I2 system have been performed by means of X-ray diffraction, thermogravimetric and calorimetric techniques. Crystals of the compounds studied were synthesized from aqueous solutions of CsI and CdI2/HgI2 by the slow evaporation of water. LÄS MER
