    Detta är en avhandling från Stockholm : KTH

    Författare :Anders Eliasson; KTH.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Liquid phase sintering; heavy metal; particle composites; tungsten; penetration; agglomerate separation; particle interaction; parabolic flight; sounding rockets; microgravity; Kirkendall effect; TECHNOLOGY Chemical engineering Metallurgical process and manufacturing engineering Metallurgical process engineering; TEKNIKVETENSKAP Kemiteknik Metallurgisk process- och produktionsteknik Metallurgisk processteknik;

    Sammanfattning : The initial stage of liquid phase sintering, involving liquid penetration, agglomerate separation, particle spreading and growth has been investigated in experiments using tungsten heavy alloys. The particle composites used were produced by hot isostatic pressing (HIP) of pure powder mixtures of W-Ni-Fe-(Co). LÄS MER

    Detta är en avhandling från Stockholm : Metallernas gjutning

    Författare :Markus Schwind; [2010]
    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

  4. 4. Subvalent Cluster Compounds and Synthesis in Alternative Reaction Media

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Josefin Åkerstedt; KTH.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal cluster; Zintl ion; metal-organic sandwich complex; ionic liquid; X-ray diffraction; spectroscopy; crystal structure;

    Sammanfattning : With the aim of finding alternative reaction media for the synthesis of subvalent main group and transition metal cluster compounds, traditionally made through solid state reactions or in superacidic media, different alternative reaction media have been explored in this work. Room-temperature ionic liquids are amongst the more unconventional reaction media used. LÄS MER
