  1. 21. The Effect of Citric Acid on Amorphous Calcium Carbonate, Mesoporous Magnesium Carbonate and Calcium Magnesium Composite : A brief study

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Abbas Jafari; [2021]
    Keywords : Carbonate Materials; Porous Materials; Carbon Dioxid Sorption; Point Sources; Amorphous Calcium Carbonate; Mesoporouse Magnesium Carbonate; Calcium Magnesium Carbonate Composite;

    Abstract : During the past decades, emission of greenhouse gases has accelerated to unsustainable levels. This is a serious issue that can have a devastating impact on everything from global economy to the terrestrial or marine ecosystem. A method for reducing the emission is named carbon capture and storage, which this project is based on. READ MORE

  3. 22. Linker substitution in ZIF-8 and its effect on the selective uptake of the greenhouse gases CH4, CO2 and SF6

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Daniel Hedbom; [2021]
    Keywords : ZIF-8 hybridization; Porous materials; GHG capture;

    Abstract : In this master thesis project, attempts were made to synthesize, pore size tailor, and characterize ZIF-8 and several mixed-linker ZIF structures to improve capture of the greenhouse gasses CH4, CO2, and SF6. Three experimental linkers, 2-methylbenzimidazole, 2-aminobenzimidazole, and 5-nitrobenzimidazole were chosen to gradually substitute 2-methylimidazole as the linker in ZIF-8. READ MORE

  4. 23. Development of a porous material from cellulose nanofibrils

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Hedda Törneman; [2021]
    Keywords : CNF; cellulose nanofibrils; xerogels; aerogels; cross-linking; porous materials; polymers;

    Abstract : Cellulose nanofibrils are a biobased and renewable material with potential to be used in many different applications. Such applications include air filtration, absorption of liquids, and thermal insulation.  To be used for these applications the cellulose nanofibrils must form a porous and dry material. READ MORE

    Abstract : The work presented in this thesis was conducted at Uppsala University and at Swerim AB. The study aims to broaden the knowledge about the corrosion of additively manufactured bioresorbable alloy WE43 in humanlike conditions for future applications. READ MORE

  6. 25. BICONTINUOUS MACROPOROUS MATERIALS FROM EPOXY RESIN-BASED MONOLITHS

    University essay from Umeå universitet/Kemiska institutionen

    Author : Thuy Trân Ho-Thi; [2021]
    Keywords : ;

    Abstract : In this project, hydrophilic bicontinuous microporous materials were synthesized via one‑pot polycondensation, using epoxy compounds and polyamines as the main monomer and curing agents. To achieve this goal, two approaches have been taken. READ MORE
