    Author : Sagar Ghorai; Peter Svedlindh; Martin Sahlberg; Gabriella Andersson; Ekkes Brück; Uppsala universitet; []
    Keywords : Magnetocaloric effect; Adiabatic temperature change; Direct measurement of magnetocaloric effect; Griffiths phase; Magneto-elastic transition; Magneto-structural transition; Second-order magnetic phase transition; First-order magnetic phase transition; Isothermal magnetic entropy change; Fysik; Physics;

    Abstract : The energy-efficient and environmentally friendly alternative cooling technology based on the magnetocaloric effect (MCE) is discussed in this thesis. The thesis has two major parts, one devoted to material characterization and the other to instrument development. READ MORE

  6. 19. MAX phase thin films : unique multifunctional ceramics with the elements Ti, Si, Ge, Sn, and C

    Author : Jens Emmerlich; Wolfhard Möller; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thin solid films; Single-crystal; Physics; Fysik;

    Abstract : Mn+1AXn phases are ternary carbides or nitrides (X) consisting of an early transition metal (M), and (A)- group element (group III-V). They combine ceramic and metallic properties with high oxidation and thermal shock resistance as well as low resistivity. READ MORE

  7. 20. Kinetic Measurements Using Nanoplasmonic Sensing

    Author : Markus Schwind; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sn Nanoparticles; Sensing; Localized Surface Plasmon Resonances; Particle Plasmon; Metal Oxidation; Metal Corrosion; Solid-Liquid Phase Transition; Kinetics; Al Nanoparticles;

    Abstract : In this thesis the nanoplasmonic sensing technique was used to study kinetics of (i) the oxidation of Al nanoparticles in air and water and (ii) the solid-liquid phase transition in Sn nanoparticles. The nanoplasmonic sensing technique detects changes of the localized surface plasmon resonance (LSPR) in metal nanoparticles. READ MORE
