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

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

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

    Sammanfattning : 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. LÄS MER

  3. 7. Design, synthesis and characterization of Dimethylammonium / Ethylammonium / Cesium Lead  Halide Perovskites for optoelectronic applications

    Kandidat-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Elin Ljungström; Ellen Hådén; Lukas Lekberg; Nima Taherpour; [2020]
    Nyckelord :Perovskit; solcell; perovskitsolcell; halvledare; organiska oorganiska perovskiter;

    Sammanfattning : The world is facing a climate crisis and to be able to solve it society needs to decrease the use of fossil fuels and find renewable alternatives. Solar energy is a great contender for a renewable energy source since it can be harvested for eternal time. LÄS MER

  4. 8. Fused deposition modeling of API-loaded mesoporous magnesium carbonate

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

    Författare :Andreas Abdelki; [2020]
    Nyckelord :Additive manufacturing; 3D-printing; Fused deposition modeling FDM ; Fused filament fabrication FFF ; Drug delivery; Amorphous drugs; Mesoporous magnesium carbonate; Upsalite; Cinnarizine; Hydroxypropyl cellulose HPC ; Hydroxypropyl methylcellulose acetate succinate HPMCAS ; Klucel ELF; AquaSolve LG;

    Sammanfattning : In this thesis, the incorporation of drug loaded mesoporous magnesium carbonate as an excipient for the additive manufacturing of oral tablets by fused deposition modeling was investigated. Cinnarizine, a BCS class II drug, was loaded into the pores of the mesoporous material via a soaking method, corresponding to a drug loading of 8.68 wt%. LÄS MER

  5. 9. Method development of an in vitro vertical Franz diffusion cell system to assess permeation of cosmetic active ingredients

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - Ångström

    Författare :Johanna Mattiasson; [2020]
    Nyckelord :chemistry; method development; Upsalite; Disruptive Materials; Franz; diffusion; penetration; permeation; skin; pharmaceuticals; cosmeceuticals; skincare; cosmetics; actives; mesoporous; material chemistry; kemi; kosmetika; Upsalite; Disruptive Materials; Franzcell; diffusion; läkemedel; metodutveckling; hud; penetration;

    Sammanfattning : For evaluation of potential skincare ingredients, an in-house method using Static Franz diffusion cells and dialysis membranes was developed. Benzoic acid was chosen as a model substance along with L-ascorbic acid and α-Tocopherol. The cell conditions were tailored to encourage transmembrane diffusion. LÄS MER

  7. 10. 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
