  1. 1. Renewable Energy and Nutrient Valorization from Anaerobic Digestion : Resource-Efficient Solutions

    Författare :Sandra Carlos-Pinedo; Zhao Wang; Ola Eriksson; Shveta Soam; Henrik Wenzel; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid-state anaerobic digestion; methane yield; digestate; systems analysis; modelling; life cycle assessment; Torrötning; metanutbyte; biogödsel; systemanalys; modellering; livscykelanalys;

    Sammanfattning : This thesis presents a comprehensive analysis aimed at understanding process performance, methane yield, and key influencing factors within the context of solid-state anaerobic digestion (SS-AD). SS-AD is used to treat organic material with high solids content, which can be challenging to address by alternative methods. LÄS MER

  3. 2. Computer Modelling of the Interaction between Water and Complex Solid Phases

    Författare :Susanne Börjesson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SOLISOL; thermodynamic model; complex solid; cement; PHREEQE; repository; PASSIPHIC; leaching; solid solution;

    Sammanfattning : In this work the program package PASSIPHIC is described. The program has been developed to calculate the equilibrium for an aqueous phase in contact with a complex solid. The complex solid is considered as consisting of pure minerals and /or solid solutions. Cement has been used as an example. LÄS MER

  4. 3. Influence of solid solutions on the properties of some apatite-type calcium salts relevant to the production of phosphate and silicate cements

    Författare :Simon Jegou Saint-Jean; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Materiallära; materialteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Material technology; isothermal calorimetry.; Rietveld method; X-ray diffraction; silicon; strontium; Portland cement; calcium phosphate cement; chlorellestadite; Solid solutions; apatite;

    Sammanfattning : The effects of non-stoichiometry and isomorphic substitutions on the properties of some apatite-type compounds were investigated. These investigations were performed both in the fields of Portland cement chemistry and apatitic calcium phosphate-based biocements. LÄS MER

  5. 4. Innovative seismic imaging solutions : From hardrock mineral exploration to quick-clay site characterization

    Författare :Tatiana Pertuz; Alireza Malehmir; Cesare Comina; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seismic methods; mineral exploration; quick-clays; seismic imaging; seismic characterization; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : Seismic methods are an efficient and powerful tool to explore the subsurface. It principally helps to gain information on the subsurface structure, bedrock topography, and the nature of the host rock. LÄS MER

  7. 5. Methodological studies in solid phase synthesis : Linkers and applications of multi-component condensations

    Författare :Mikael Erlandsson; Anders Undén; Thomas Norberg; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Solid phase peptide synthesis; solid phase organic chemistry; linkers; self-scavenging; safety catch linker; cyclic peptides; reductive acidolysis; disulfides; reduction; metallic zinc; multi-component condensations; combinatorial chemistry; Neurochemistry; Neurokemi;

    Sammanfattning : Solid phase synthesis has become an increasingly important tool in the synthesis of oligopolymers and small organic molecules. This thesis covers three important areas in the solid phase synthesis technique: linker strategies, reduction methods and novel routes to complex heterocycles. LÄS MER
