  1. 1. Methods to study device induced aggregation of proteins

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Marie Therese von Wowern; [2023]
    Nyckelord :protein formulation; protein aggregation; insulin; silicone oil; syringe; shear stress; subvisible particle; size exclusion chromatography; flow imaging microscopy; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : This work developed a method for the investigation of how medical devices, such as syringes and needles, affect the formation of subvisible particles in a protein drug without excipients. Protein-based pharmaceuticals are well known to be sensitive to different kinds of stress, and exposure to stress during the use of this device is unavoidable. LÄS MER

  3. 2. How is carbon stored in boreal forest soils? - A method development which investigates at what protein concentration ferrihydrite and goethite are saturated.

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Louise Berild; [2023]
    Nyckelord :Soil nitrogen; soil carbon; boreal forest; ectomycorrhizal fungi; decomposition; adsorption; ferrihydrite; goethite; Earth and Environmental Sciences;

    Sammanfattning : Boreal forests store the majority of their carbon in the soil and play an important role in the global carbon cycle. However, the mechanisms that control carbon storage in boreal soils are not well understood. LÄS MER

  4. 3. Suspensions of Calcium Phosphate : Interactions of milk proteins to hydroxyapatite

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Ying Chen; [2023]
    Nyckelord :Calcium fortification; Milk proteins interactions; Colloid chemistry; Food technology; engineering and nutrition; Agriculture and Food Sciences;

    Sammanfattning : Capolac is a product containing hydroxyapatite (HA) from Arla Food Ingredients, to be used for calcium fortification. The adsorption of casein and whey proteins onto the Capolac was investigated, aiming to solve the sedimentation problem of this insoluble calcium phosphate. LÄS MER

  5. 4. On-chip characterization of hydroxyapatite with different topography

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Maja Grape; [2022]
    Nyckelord :biomaterials; calcium-deficient hydroxyapatite; microfluidic systems;

    Sammanfattning : Biomaterials are defined as non-viable materials whose functions strives to interact with biological systems, this makes biomaterials suitable for medical devices and applications. Biomaterials biological properties must be thoroughly investigated and evaluated in order to be approved for clinical usage. LÄS MER

  7. 5. Orbit-simulator for downstream processes

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Andreas Malmström; [2022]
    Nyckelord :Chemical engineering; Process simulation; Downstream processes; Orbit; Preparative chromatography; Python; Lumped Rate Models; Technology and Engineering;

    Sammanfattning : In an ever more digitilized society, the transition is palpable also in the pharmaceutical industry. The control system Orbit was developed at the department of chemical engineering at Lund University, to be able to automate downstream processes based on the ÄKTA-system. LÄS MER
