  1. 26. Converting Poultry Feather Waste into Bioplastics using Green Modifying Agents

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Marc Jirström; [2021]
    Keywords : polymer technology; materials science; renewable materials; Technology and Engineering;

    Abstract : Handling of problematic waste material, and the use of fossil-based and non-biodegradable plastics are two major sustainability challenges. By developing solutions that convert waste material to bioplastics, it is possible to address both these issues. READ MORE

  3. 27. Effects of skin care ingredients on keratinocytes : - Interplay between osmotic stress, cell viability, and gene expression towards increased understanding of keratinocyte differentiation

    University essay from Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Author : Kassem Awad; [2021]
    Keywords : Cell viability; Keratinocytes; Osmotic stress; qPCR; Skin; Water activity;

    Abstract : The epidermis is composed of multiple cell strata where viable keratinocytes, in the basal layer (stratum basale (SB)), go through a range of steps with the final stage of being dead corneocytes in the outer most layer (stratum corneum (SC)). The differentiation, which can be thought of as programmed cell death, include several key processes that are essential for an intact skin barrier.

  4. 28. Search for Preserved Methanogenic Organisms in Ophiolitic Rocks through Lipid Biomarker Analysis – Implications for Astrobiological Explorations

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Alexandra Zetterlind; [2020]
    Keywords : ophiolite; deep biosphere; archaea; methanogenesis; chemosynthesis; serpentinite-hosted ecosystems; lipid biomarkers; astrobiology; ofiolit; djupbiosfär; arkeér; metanogener; kemosyntes; serpentinit-drivna ekosystem; lipidbiomarkörer; astrobiologi;

    Abstract : Serpentinization is a metamorphic low-temperature geological process, involving a series of chemical reactions that hydrate ultramafic rocks into serpentines and other minerals such as magnetite and brucite. Moreover, the process produces heavily reducing and highly alkaline fluids together with molecular hydrogen (H2) and methane (CH4), which have the capacity to support chemosynthetic microbial life.

  5. 29. Evaluation of Carbon Source Addition on Denitrification Efficiency : A study in a continuous biological leachate water treatment system.

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Isac Ingfeldt; [2020]
    Keywords : denitrification; nitrification; WWTP; carbon source; ethanol; glycerol; Brenntaplus VP1; nitrate; pilot;

    Abstract : In 2014 SÖRAB constructed a continuous biological treatment system (KBR) to handle leachate waterfrom the landfill at the facility in Löt, north of Stockholm. The KBR is mainly focused on removal ofammonium nitrogen which would otherwise be released in to the recipient and contribute toeutrophication and damage to the environment. READ MORE

  6. 30. Deep Eutectic Solvents and Their Possible Application in Transdermal Drug Delivery

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Sarah Lindblom; [2020]
    Keywords : Deep Eutectic Solvents; Pharmaceuticals; Transdermal drug delivery; Choline Chloride; Rheology; Formulation; BSA; Franz cell diffusion; Pharmaceutical technology; Läkemedelsteknologi; Technology and Engineering;

    Abstract : Deep eutectic solvents, DES, is a type of solvent made by mixing a quaternary ammonium salt with a hydrogen bond donor at the eutectic point of the system. Most common quaternary ammonium salt is Choline Chloride, ChCl. A specific DES, Choline:CAGE has shown promise in delivering insulin through the skin of mice. READ MORE
