  1. 11. Evaluation of antioxidant effect of an algae extract on skin: in vitro study

    University essay from Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Author : Oday Al Mustafa; [2023]
    Keywords : Algae extract; antioxidant; DPPH; microalgae; ROS; skin covered oxygen electrode; skin;

    Abstract : Algae extracts are used as cosmetic products and used as additives in specific foods because of their antioxidant activity. Reactive oxygen species (ROS) such as hydrogen peroxide and superoxide radicals are toxic on the skin and can be scavenged by antioxidants, which are abundant in microalgae. READ MORE

  3. 12. Permeation studies of Niacinamide and its effect on human skin

    University essay from Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Author : Andebrhan Fsahaye; [2023]
    Keywords : niacinamide; permeation; human skin; impedance; hydration;

    Abstract :  Background: Niacinamide (NIA) is one of the most commonly used cosmetic ingredients. It belongs to the vitamin-B3 family and has extensive dermatological therapeutic benefits. NIA has been proven to be a useful skincare product in serving as anti-acne agent, preventing skin hyperpigmentation, removal of wrinkles from the face etc. READ MORE

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

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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. READ MORE

  5. 14. SINGLE AND COMBINED EXPOSURE OF POLYSTYRENE NANOPARTICLES AND NORTH SEA MARINE OIL IN TWO IN VITRO FISH MODELS

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Monica Olsson; [2022-10-05]
    Keywords : Polystyrene nanoparticles; crude oil; combined toxicity; cytotoxicity; oxidative stress;

    Abstract : The awareness of micro-and nanoplastic pollution and its impact on the marine ecosystem has increased over the last decade. Nanoplastics may affect aquatic organisms since their small size and high surface-to-volume ratio increases their bioavailability and ability to cross biological membranes. READ MORE

  6. 15. Techno-Economic Assessment of High-Temperature H2O/CO2 : Co-Electrolysis in Solid Oxide Electrolysers for Syngas Production

    University essay from KTH/Kemiteknik

    Author : Shivani Ramprasad Jambur; [2022]
    Keywords : Co-electrolysis; Power-to-X; Process modeling; Green Syngas; Solid-Oxide Electrolyser;

    Abstract : High-temperature Co-electrolysis of H2O and CO2 in a solid-oxide electrolyser (Co-SOE) for syngas production is a high-efficiency renewable electricity conversion and storage method part of the Power-to-X technologies. Syngas, a mixture of H2, CO and CO2, is a critical building block to make several chemical and synthesis fuels. READ MORE
