  1. 26. Conductive metal-organic frameworks (MOFs) and possible applications

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Meghdad Hosseinzadegan; [2022]
    Keywords : ;

    Abstract : Metal-organic frameworks (MOFs) are a class of hybrid organic/inorganic materials with permanent porous structure. Whilst there are virtually endless possible selection of metal ions and organic ligands to build up a MOF structure, intrinsically conductive MOFs are rare, relatively new, and our knowledge on their conductivity and charge transport mechanisms is limited.

  3. 27. Underground Thermal Energy Storage for District Heating : A Feasibility Study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emma Arnfelt; [2022]
    Keywords : ;

    Abstract : Global warming is one of the largest challenges and most important issues within the energy sector. As the society’s demand for energy increases, the environmental impact must continue to decrease to reach global targets. READ MORE

  4. 28. Investering i spannmålsanläggning : en fallstudie av nya spannmålsanläggningar

    University essay from SLU/Dept. of People and Society

    Author : Carl-Magnus Kolm; Claes Sjöberg; [2022]

    Abstract : Abstract The management and handling of organic waste in primarily low-income developing cities, due to high urbanization has become a global problem. The main form of waste handling in these cities are landfilling, due to it being the cheapest and easiest option. READ MORE

  6. 30. Comparing different methods of measuring particle size for pharmaceutical excipients

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Jiawen Wang; [2022]
    Keywords : particle size; comparison; Malvern analysis; Qicpic analysis; Pharmaceutical technology; Technology and Engineering;

    Abstract : In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by laser diffraction analysis (Malvern wet and dry), dynamic image analysis (Qicpic), and microscopic methods (Qicpic, SEM, and light microscopy) to determine the applicability and limitations of each method, as well as to clarify their advantages and disadvantages.
