  1. 1. Utveckling av metoder för mätning av stabilitet hos hydrokolloider – Metylcellulosa som konsistensgivare i köttersättningsmix.

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Louise Engström; [2022]
    Nyckelord :Hydrocolloid; cellulose; methylcellulose; emulsion; gel; Hydrokolloid; cellulosa; metylcellulosa; emulsion; gel;

    Sammanfattning : Emulsioner bildas då två vätskor som normalt sätt inte blandas med kraft vispas samman för att distribuera den ena vätskan i den andra. För att dessa vätskor inte efter avslutad vispning ska gå isär kan emulgeringsmedel tillsättas, till exempel polysackarider som hör till hydrokolloiderna. 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. Formulation of nanoemulsions stabilized by cellulose nanocrystals

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

    Författare :Marco Maccagno; [2020]
    Nyckelord :nanocellulose; hydroxypropyl methilcellulose; Pickering emulsions; microfluidization; drug delivery; nanocellulosa; hydroxipropylmetylcellulosa; Pickering emulsioner; microfluidization; drogleverans;

    Sammanfattning : Cellulose nanocrystals (CNCs) are bio-based nanoparticles with the ability to stabilize oil and water emulsions thanks to their intermediate wettability and nanometric size. These and other types of particle-stabilized emulsions, commonly referred to as Pickering emulsions, are of great academic and industrial interest due to their superior stability against drop coalescence compared to classical surfactant-stabilized emulsions.

  5. 4. Studie av en jordglob från sent 1920-tal Problematiken i fernissat papper på metall

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Sofia Lundsten; [2019-06-19]
    Nyckelord :globe conservation; metal sphere globe; varnished paper; paper on metal;

    Sammanfattning : This project is an object study of a late 1920s terrestrial globe now owned by the Department of Earth Sciences at the University of Gothenburg. Published by the Swedish company P.A. Norstedt & Söner in Stockholm and printed in Berlin, the globe presents an unusual combination of materials; paper gores on a metal sphere. LÄS MER

  7. 5. Comparison of anaerobic sludge granules from different wastewater plants with respect to granule size, substrate degradation and methanogenic community

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Jonathan Andrén; [2018]
    Nyckelord :anaerobic digestion; granule; UASB; EGSB; VFA; methanogen; acetoclastic; hydrogenotrophic; acetogenic; mcrA; ; T-RFLP; methanosarcina; methanosaeta;

    Sammanfattning : Within the objective to replace fossil fuel with sustainable sources there is a growing pressure to advance such development. Anaerobic digestion (AD) is beneficial not only as a waste management technology, but also to recycle organic waste into methane which can be used for heating, production of electricity or vehicle fuel.
