  1. 1. Modeling transport phenomena with COMSOL Multiphysics - Adsorptive membrane fouling in lignocellulosic biorefineries and lessons learned from it

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Linnéa Petersson; [2020]
    Nyckelord :QCM-D; Quartz crystal microbalance with dissipation monitoring; Hemicellulose; GGM; Galactoglucomannans; Adsorption; Membrane fouling; COMSOL; Chemical engineering; Kemiteknik; Technology and Engineering;

    Sammanfattning : The separation of hemicelluloses, like glactoglucomannans, from lignocellulosic process streams is an important step in building profitable lignocellulosic biorefineries. The most common method for the separation is membrane filtration, however, it has the draw-back of being sensitive to membrane fouling. LÄS MER

  2. 2. Effect of Dextrans on Cryopreservation of Human Spermatozoa

    Master-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Författare :FIE BARBARA Nordskov Harder; [2019]
    Nyckelord :Dextran;

    Sammanfattning : Cryopreservation is a process where a sample, e.g. cells or tissue, is preserved by cooling to sub-zero temperatures, usually -196°C. Upon freezing these materials, ice crystals form, which eventually results in cell death. LÄS MER

  4. 4. Customer Based Business Development : Strategic Challenges for a Small Research-Based Spin-Off Enterprise

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - BMC

    Författare :Viktor Rognås; Hanna Stenberg; [2017]
    Nyckelord :;

    Sammanfattning : The biotechnology industry is one of the fastest growing sectors of the western economy. The biotech industry is helping the world by creating significant societal and economic value in various sectors. However, as a result of the fast development of the biotech industry, the environment is constantly changing and doing so at a high pace. LÄS MER

  5. 5. Nanoparticle Removal and Brownian Diffusion by Virus Removal Filters: Theoretical and Experimental Study

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Olof Gustafsson; [2017]
    Nyckelord :virus removal filtration; Péclet number; nanocellulose; hydrodynamic constraint; convective capture; diffusion;

    Sammanfattning : This study aims to examine the throughput of nanoparticles through a Cladophora cellulose based virus removal filter. The effect of Brownian motion and flow velocity on the retention of 5 nm gold nanoparticles, 12.8 nm dextran nanoparticles and 28 nm ΦX174 bacteriophages was examined through MATLAB simulations and filtration experiments.
