  1. 11. Transition Metal Nitrides : Alloy Design and Surface Transport Properties using Ab-initio and Classical Computational Methods

    Författare :Davide G. Sangiovanni; Valeriu Chirita; Lars Hultman; Paul Mayrhofer; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Enhanced toughness in brittle ceramic materials, such as transition metal nitrides (TMN), is achieved by optimizing the occupancy of shear-sensitive metallic electronic-states. This is the major result of my theoretical research, aimed to solve an inherent long-standing problem for hard ceramic protective coatings: brittleness. LÄS MER

  3. 12. Algorithms and Interaction Potentials: phase density, surface tension and carbon dioxide

    Författare :Rasmus Persson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; surface tension; carbon dioxide; density of states; bicalutamide;

    Sammanfattning : This thesis is an amalgamation of articles (Papers I–V) by the author. We present a perturbation algorithm to calculate the phase density, and thus the partition function including its temperature dependence. LÄS MER

  4. 13. Microstructure and Inclusion Characteristics in Steels with Ti-oxide and TiN Additions

    Författare :Wangzhong Mu; Pär Jönsson; Keiji Nakajima; Casper Van der Eijk; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; intragranular ferrite; oxide metallurgy; inclusion engineering; titanium nitride; titanium oxide; inclusion size; heterogeneous nucleation; critical diameter; confocal laser scanning microscopy CLSM ; differential scanning calorimetry DSC ; continuous cooling transformation CCT diagram.; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : Non-metallic inclusions in steels are generally considered to be detrimental for mechanical properties. However, it has been recognized that certain inclusions, such as Ti-oxide and TiN, can serve as potent nucleation sites for the formation of intragranular ferrite (IGF) in low-alloy steels. LÄS MER

  5. 14. Kinetic Measurements Using Nanoplasmonic Sensing

    Författare :Markus Schwind; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
