  1. 1. Optimising microfluidic preparation of lipid sponge phase nanoparticles for biomolecule encapsulation

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Owais Khalil; [2023]
    Nyckelord :Sponge phase; lipid nanoparticles; microfluidics; SAXS; cryo-TEM; DLS; chemical engineering; Chemistry;

    Sammanfattning : Drug delivery with lipid nanoparticles, especially sponge phase lipid nanoparticles (LNP), has been well studied because of its ability for drug encapsulation and transferring the drug through the cell membrane. The sponge phase LNP formulation could be affected by the molecular structure of the lipid, the temperature, pH, dilution, the buffer, and the addition of a stabiliser. LÄS MER

  3. 2. The effect of temperature on the chemical stability of Vitamin C in a cosmetic product – Development of an HPLC-method for quantitative analysis

    Master-uppsats, KTH/Tillämpad fysikalisk kemi

    Författare :Sofia Thuresson; [2022]
    Nyckelord :Vitamin C; HPLC; Stability; Degradation; Antioxidant; Vitamin C; HPLC; Stabilitet; Nedbrytning; Antioxidant;

    Sammanfattning : Vitamin C är en populär ingrediens i hudvårdsprodukter, bland annat på grund av dess positiva effekter på kollagen-produktionen i huden och dess antioxidativa egenskaper. Dessvärre är vitamin C en känslig ingrediens som lätt bryts ned av ljus, syre, hög temperatur eller fel pH-värde. LÄS MER

  4. 3. Aluminium water extract levels from liquid packaging board : A comparative trial study between alum and polyaluminium chloride added as flocculants on BM7, Stora Enso Skoghall Mill

    Master-uppsats, Karlstads universitet/Avdelningen för kemiteknik

    Författare :Hanna Cassel; [2022]
    Nyckelord :aluminium; alum; polyaluminium chloride; PAC; liquid packaging board; BfR; water extract; aluminium; alun; polyaluminiumklorid; PAC; vätskekartong; BfR; vattenextrakt;

    Sammanfattning : The aluminium content of water extracts is an important aspect for the food safety of paper board, as the content indicates the ability of the paper board material to transfer aluminium to the packaged food product. Aluminium intake in humans and its health effects have been discussed for many years as some research has seen potential links between, among other things, high aluminium levels in the brain and the development of hereditary Alzheimer's.

  5. 4. Characterization of PLA Nanoplastics, and Their Effects on Daphnia magna

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Melinda Rydberg; [2022]
    Nyckelord :Polylactic acid; Polylactide; PLA; Nanoplastic; Daphnia magna; Toxicity; Polymer Technology; Chemistry; Earth and Environmental Sciences;

    Sammanfattning : As plastic pollution in aquatic environments keeps happening it has become more and more important to learn more about nanoparticles. Bio-based and biologically degradable plastics, such as polylactic acid (PLA), are gaining popularity and it is therefore important to determine whether they break down into nanoplastics or not.

  7. 5. Sorption of novel side-chain fluorinated polymers to sediment - the impact of pH

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Hanna Erléus; [2022]
    Nyckelord :Scotchgard™; sorption; sediment; pH; side-chain fluorinated polymer surfactants; Lake Hjälmaren.;

    Sammanfattning : Fluorinated compounds are produced on a large scale and their releases are contaminating the environment. Among these are side-chain fluorinated polymers found in technical mixtures of Scotchgard™, which are used as surfactants in fabric coating. LÄS MER
