  1. 1. Surface functionalization of cellulose fibers and exploration of its influence in ion exchange chromatography

    University essay from KTH/Fiber- och polymerteknologi

    Author : Anna Wessén; [2023]
    Keywords : Ion-exchange chromatography; membrane chromatography; surface extension; grafting; copolymerization; free-radical polymerization; Jonbyteskromatografi; membrankromatografi; ytförlängning; ympning; sampolymerisation; fri radikal polymerisation;

    Abstract : Kromatografiska metoder kan användas för en mängd olika tillämpningar, inklusive separation, rening och analys av biomolekyler och kemikalier. Membrankromatografi är en av de nya kromatografiteknikerna som expanderar snabbt eftersom den tillåter hög masstransport genom den stationära fasen, vilket resulterar i en mer tidseffektiv process.

  3. 2. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Lina Näslund; Gabriella Petersson; [2023]
    Keywords : Membrane filtration; Ultrafiltration; Microfiltration; Dialcohol cellulose; DAC; Bioplastics; Chemical engineering; Process design; Technology and Engineering;

    Abstract : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. READ MORE

  4. 3. Analyzing Synthetic Spider Silk-based Diffraction Grids for the Sunshade Project

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Johanna D'Ciofalo Khodaverdian; Amira Karlsson; [2023]
    Keywords : Sunshade project; Diffraction grating; Artificial spider silk; Climate change; Geoengineering;

    Abstract : To mitigate climate change a proposed space-based geoengineering solutionis to screen off solar irradiance by placing a membrane in between the Earthand the Sun. The feasibility of such a project largely depends on minimizingthe mass of the shading screen and as an extension to the Sunshade projectthis thesis investigated how such a low-mass membrane could be designed.

  5. 4. Identifying effects of adrenaline and dopamine binding on the beta2-adrenergic receptor structure and function using machine learning

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Joar Gunnarsson; Leon Bergner; [2023]
    Keywords : beta2-adrenergic receptor; GPCR; adrenaline; dopamine; Machine learning; Molecular dynamics simulation;

    Abstract : The beta2-adrenergic receptor is a G-protein coupled receptor, involved in several physiological processes, which enables signaling through the cell membrane. To study the effect of dopamine and adrenaline binding on the receptor structure and function, we used machine learning methods applied to data from molecular dynamics simulations. READ MORE

  6. 5. Let Us Put Our Brains in the Spotlight – Literally!

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Elsa Karjalainen; [2023]
    Keywords : Biology and Life Sciences;

    Abstract : Neurons are the working force in each vertebrate’s nervous system. These small cells have the important task of transferring information in the form of electrical charges called action potentials. Neurons make it possible for us to sense touch, process our environment, and store memory. READ MORE
