  1. 1. Development of alkaline earth metal-based, metal-organic frameworks for greenhouse gas sorption

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Ali Maghsoodpoor; [2022]
    Nyckelord :Metal-organic Framework; gas sorption;

    Sammanfattning : Metal-organic frameworks (MOFs) constructed from metal atoms connected by organic linkers have received extensive attention for greenhouse gas separation in the past decades. Moreover, their large surface area makes them a promising candidate as adsorbents for gas sorption. LÄS MER

  3. 2. 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

  4. 3. 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

  5. 4. Novel Hybrid Nanomaterials : Combining Mesoporous Magnesium Carbonate with Metal-Organic Frameworks

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

    Författare :Viktor Sanderyd; [2018]
    Nyckelord :Nanomaterials; Metal-Organic Frameworks; MOF; MMC; Porous; Mesoporous; Upsalite; Hybrid materials; Core-shell;

    Sammanfattning : Nanotechnology as a field has the potential to answer some of the major challenges that mankind faces in regards to environmental sustainability, energy generation and health care. Though, solutions to these concerns can not necessarily rely on our current knowhow. LÄS MER

  7. 5. 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
