  1. 16. Development of Nanoporous Inorganic Carbonates for Pharmaceutical and Environmental Applications

    Författare :Maria Vall; Ocean Cheung; Maria Strømme; Jessica Rosenholm; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mesoporous magnesium carbonate; drug delivery; water purification; CO2 capture; catalysis; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : Mesoporous magnesium carbonate (MMC) is a highly porous, anhydrous material which can be synthesized without the use of templates. This thesis shows how post- and in synthesis modification of MMC can create porous inorganic carbonates suitable for different pharmaceutical and environmental applications. LÄS MER

  3. 17. Nanocomposites of Cellulose and Conducting Polymer for Electrical Energy Storage

    Författare :Henrik Olsson; Leif Nyholm; Maria Strømme; Martin Sjödin; Johan Bobacka; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polypyrrole; Nanocomposites; Energy storage; Conducting polymers; Cellulose; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : The world’s increased energy storage demand, as well as the environmental concerns related to the combustion of fossil fuels, has triggered a transition to intermittent renewable energy sources as well as to electrical and hybrid vehicles. Current day rechargeable batteries are, due to the invention and development of lithium ion batteries, technologically well positioned to answer to some of these demands. LÄS MER

  4. 18. Porous Sorbents for Environmental Applications and Selective Laser Sintering 3D Printing of Dosage Forms

    Författare :Michelle Åhlén; Ocean Cheung; Maria Strömme; Jonas Lindh; Christel Bergström; Carlos Grande; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metal-organic frameworks; zeolitic imidazolate frameworks; mesoporous magnesium carbonate; greenhouse gas capture; adsorption; adsorption kinetics; additive manufacturing; selective laser sintering; personalized medicines; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : The rising levels of greenhouse gas emissions from vehicular and industrial pollution constitute a serious concern not only for the environment but for our entire society. Traditional gas capture and separation techniques, such as amine scrubbing for CO2 gas separation, have been commonly used at a commercial scale, however issues relating to high costs and high energy requirements for sorbent regeneration have limited the efficiency of many of these techniques.
