  3. 2. Parameters Controlling Distribution of Diagenetic Alterations within Fluvial and Shallow Marine Sandstone Reservoirs : Evidence from the Libyan Basins

    Författare :Muftah Khalifa; Hemin Koyi; Joao Marcelo Medina Ketzer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diagenesis; Structural setting; Depositional facies; Basin thermal history; Ther- mal Hot basinal brines; Fluid inclusions; Raman Spectrometry; Stylolites; Hydro-carbon migration; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Sammanfattning : This thesis demonstrates that geological setting, depositional facies, open system flux of hot basinal brines and descending of shallow waters have a strong impact on the distribution of the diagenetic alterations within continental and paralic/shallow marine sandstones which in turn control the quality and heterogeneities of the reservoirs.Geological setting controls the mineralogical and textural maturity of sandstone, whereas depositional facies control the pore water chemistry (marine, brackish or meteoric), sedimentary texture and sand body geometry.

  4. 3. Elucidating Chemical and Electrochemical Side-Reaction Mechanisms in Li-ion Batteries

    Författare :Neeha Gogoi; Erik Berg; M. Rosa Palacín; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion battery; solid electrolyte interphase; electrolyte additives; reaction mechanism; ethylene carbonate; vinylene carbonate; tris trimethylsilyl phosphate; surface enhanced Raman spectroscopy; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : Lithium-ion batteries constitute a leading technology that plays a major role in the transition towards sustainable transportation and power generation. The stability of modern batteries relies on a passivation layer formed on the negative electrode known as the solid electrolyte interphase (SEI). LÄS MER

  5. 4. Adipose Tissue Heterogeneity - Development and Application of Nonlinear Microscopy Methods

    Författare :Alexandra Paul; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; least squares decomposition; stem cells; multivariate spectral analysis; obesity; adipose tissue; adipogenesis; broadband coherent anti-Stokes Raman scattering; extracellular matrix;

    Sammanfattning : Although the negative health impacts of obesity have been well documented, the number of overweight or obese patients has and is predicted to continue rising. One of the causal factors of obesity is a constant positive energy balance mainly from excessively high caloric intake from food compared with limited physical activity (caloric expenditure).

  7. 5. Modified molecular sieve macrostructures

    Författare :Valeri Naydenov; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : The preparation of molecular sieve based catalysts in appropriate macroforms suitable for practical utilization is of great technological importance. This thesis is dedicated to the preparation of metal containing molecular sieve macrostructures (modified macrostructures). LÄS MER
