  1. 1. Depth-resolved Raman Spectroscopy and X-ray Photoelectron Spectroscopy to Evaluate the Structural and Chemical Properties of Chemically Strenghtened Glasses

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Felix Bengtsson; [2020]
    Nyckelord :;

    Sammanfattning : In this thesis, the structural and chemical properties of a series of titanosilicate glasseswere investigated. The glasses were subjected to a chemical strengthening process(with K^+ replacing Na^+) at four different treatment temperatures and studied withXPS- and Raman spectroscopy. LÄS MER

  3. 2. Investigation into the Loess-Palaeosol and Red Clay Record from the Pliocene- Quaternary Chinese Loess Plateau Using In-Phase and Out-OfPhase Magnetic Susceptibility

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Rebecca Jacobson; [2018]
    Nyckelord :loess; Chinese Loess Plateau; magnetic susceptibility; out-of-phase; viscous relaxation; lössjord; Kinesiska Lössjordsplatån; magnetiska känsligheter; ur-fas; viskös relaxation;

    Sammanfattning : Loess is a well sorted, fine grained, windblown (aeolian) sediment and deposits as a blanket over large areas, reaching from a few centimetres to several hundreds of meters in height and can drape large landscapes in form of mountains. During a more humid and warmer climate, redox conditions are changed in the loess deposits, with greater seasonal moisture creating greater soil formation (pedogenesis), i. LÄS MER

  4. 3. Adhesives for Load-Bearing Timber-Glass Elements : Elastic, plastic and time dependent properties

    Magister-uppsats, Linnéuniversitetet/Institutionen för bygg- och energiteknik (BE)
