  1. 1. Filtration of oil-in-water nanoemulsions for potential adjuvant development applications

    Master-uppsats, KTH/Kemiteknik

    Författare :Emilie Degeneve; [2023]
    Nyckelord :Filtration of oil-in-water nanoemulsions for potential adjuvant development applications; Vaccin; adjuvans; nanoemulsion; ytaktiva ämnen; filtrering;

    Sammanfattning : I den här studien undersöktes innovativa sammansättningar för produktion av vaccinadjuvans. Syftet var att stabilisera nanoemulsioner av olja i vatten, med hjälp av squalenolja (som används inom läkemedelsindustrin), med olika ytaktiva ämnen och att testa filtrerbarheten hos dessa nanoemulsioner.

  3. 2. Finite Element Simulation of Moisture Transport in Cellulose Insulation Material of Power Transformers

    Master-uppsats, Uppsala universitet/Tillämpad mekanik

    Författare :Luc Villibord; [2023]
    Nyckelord :;

    Sammanfattning : Power Transformers are an important and complex part of the electrical transmission technology. One of the main producers of these transformers worldwide is Hitachi Energy, for which this work has been done. LÄS MER

  4. 3. Modified cellulose synthesized by different deep eutectic solvents as an additive in paper making process

    Master-uppsats, Karlstads universitet

    Författare :Shiniar Said Saleh; [2023]
    Nyckelord :green chemistry; dry strength additives; deep eutectic solvents; sodium periodate oxidation; charge density; dewatering; mechanical strength.;

    Sammanfattning : The environmental concerns that come with the currently used traditional papermaking process where petroleum-based additives are used, has tempted researchers to study “green” additives by introducing environmentally friendly modifications of cellulose as an additive in the papermaking process. This thesis will spin further on that by producing additives with different charge densities and focus on to incorporate an etherification reaction into potentially greens systems based on non-toxic and readily biodegradable deep eutectic solvent (DES).

  5. 4. Storage period optimization of a viscous nasal spray suspension

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Lili Zsófia Domián; [2023]
    Nyckelord :Rhinocort; viscosity; rheology; thixotropy; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : The number of people suffering from the unpleasant symptoms of allergic rhinitis is increasing due to environmental and other factors. This not only makes life difficult for the individual but also places a heavy burden on society, which is why treatment is needed. LÄS MER

  7. 5. Production, Purification, and Characterization of wood substrates and Galactose oxidase enzyme

    Master-uppsats, KTH/Industriell bioteknologi

    Författare :Rakhesh Pongalikonnar Ranganathan; [2023]
    Nyckelord :Peracetic acid treatment; Galactose oxidase; Pichia pastoris; Biomass recalcitrance; Enzymatic upgrading; Perättiksyrabehandling; Galaktosoxidas; Pichia pastoris; Motsträvighet i biomassa; Enzymatisk uppgradering;

    Sammanfattning : Trä är den bästa förnyelsebara källan för att producera många produkter på grund av dess biokompatibla och biologiskt nedbrytbara natur. Träets biomassa har en motstridig natur mot enzymatisk uppgradering. LÄS MER
