  1. 11. Effect of iron redox state on crystallization behaviour of Fayalite slags

    University essay from KTH/Materialvetenskap

    Author : Paolo Mai; [2020]
    Keywords : Copper smelting; Slag; Magnesium Oxide; Iron redox equilibria; Optical basicity; Raman spectroscopy.; Smältning av koppar; Slagg; Magnesiumoxid; Järnredoxjämvikt; Optisk basicitet; Ramanspektroskopi.;

    Abstract : In the copper smelting processes, the viscosity of the matte and the slag is an important factor for establishing efficiency. Impurities in the concentrates affect the viscosity not only by changing the melt structure but also by promoting precipitation of solid phase which sharply rises it. READ MORE

  3. 12. Design and Simulation of Terahertz Antenna for Spintronic Applications

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Nils Eivarsson; Malin Bohman; Emil Grosfilley; Axel Lundberg; [2020]
    Keywords : spintronics; terahertz; THz; antenna; simulation; COMSOL multiphysics;

    Abstract : Spintronics is a spin-electronic field where the electron spinangular momentum, in conjunction with charge, is used to read andwrite information in magnetic sensors and logic circuits, e.g. hard disk drive (HDD), magnetic random access memory (MRAM) and broadband TeraHertz (THz) emitters.

  4. 13. Secondary Steel Metallurgy Slag Design and MgO-C Refractory Implications : Theoretical and Practical Considerations

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Hellgren Simon; [2019]
    Keywords : MgO-C; CaO-SiO2-Al2O3-MgO; Slag Design; Refractory Wear;

    Abstract : MgO-C based refractory materials, often used in secondary steel making, are exposed to variouswear mechanisms in its application. The wear could be divided into oxidative, chemical andabrasive categories, all behaving differently and all being influenced by different factors. READ MORE

  5. 14. Optimizing the sealing of tubular heating elements

    University essay from Lunds universitet/Materialteknik

    Author : Victor Almblad; [2019]
    Keywords : Technology and Engineering;

    Abstract : Tubular heating elements, produced by Backer AB are today commonly used, serving as systems for intelligent heating in automotive, medical and household industries. Tubular heating element consists of a mantle, resistance wire, electrical insulation (magnesium oxide) and a sealing. READ MORE

  6. 15. Investigation of magnetic order in nickel-5d transition metal systems

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Konstantinos Papadopoulos; [2019]
    Keywords : muSR; muons; skyrmions; magnetism; transition; spin; rotation; relaxation; resonance; thin; films; transition; metals; MBE; sputtering; XRR; reflectivity; molecular; beam; epitaxy; x; ray; TRIUMF; double; perovskite; longitudinal; transverse; nickel; Ni; asymmetry; positron; depolarization; chiral; lattice; helical; DM; interaction;

    Abstract : Double perovskite materials exhibit alterations in magnetic order through manipulation oftheir crystal structure. Certain ultra thin metallic bilayers can create an exotic magnetic stateof confined spin textures called skyrmions. In both cases, new atomic arrangements leadto new electrical and magnetic properties. READ MORE
