  4. 3. Nanocellulose surface functionalization for in-situ growth of zeolitic imidazolate framework 67 and 8

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Beyar Abdulla; [2020]
    Nyckelord :Zeolitic Imidazolate Framework; ZIF-8; ZIF-67; CNF@MOF; CNF@ZIF; TEMPO CNF; Nanomaterials; Nanocomposites; Metal-Organic Framework; Biopolymers;

    Sammanfattning : This master’s thesis was conducted at the Department of Nanotechnology and Functional Materials at Ångström Laboratory as part of an on-going project to develop hybrid nanocomposites from Cladophora cellulose and a sub-type of metal-organic frameworks; zeolitic imidazolate frameworks (ZIFs). By utilizing a state-of-the-art interfacial synthesis approach, in-situ growth of ZIF particles on the cellulose could be achieved. LÄS MER

  5. 4. Using Upsalite® as drug delivery vehicle : Increasing the solubility of poorly soluble drugs by stabilizing their amorphous state

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för farmaci

    Författare :Ottilia Arvén; [2017]
    Nyckelord :;

    Sammanfattning : Poor aqueous solubility is an issue not only in drug discovery and development but also for registered drug products, since poor drug solubility is often related to poor absorption (bioavailability). There are several methods available to increase the aqueous solubility and dissolution rate of pharmaceutical formulations. LÄS MER
