  1. 1. 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

  3. 2. Magnetic Activated Carbon Production from Lignin and Ferrous Salts : Process Modification for Enhanced Phosphate Adsorption from Aqueous Solutions

    Master-uppsats, KTH/Materialvetenskap

    Författare :Zhaoran Zheng; [2020]
    Nyckelord :Magnetic bio-activated carbon; phosphate adsorption; lignin; steam activation.; Magnetiskt bioaktiverat kol; fosfatadsorption; lignin; ångaktivering;

    Sammanfattning : The treatment and control of superfluous aqueous phosphate is a critical task in environmental management. Magnetic bio-activated carbon is a good adsorbent for physical adsorption methods with several environmental and economic advantages. LÄS MER

  4. 3. Fosforsorptionskapaciteten i djupa jordlager : En kemisk analys av fosforadsorption i svenska grus- och sandjordar

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Charlotte Ekstrand; Camilla Hamberg; [2019]
    Nyckelord :phosphorus; phosphate; oxalate; pyrophosphate; eutrophication; adsorption; ICP; AutoAnalyzer; fosfor; fosfat; oxalat; pyrofosfat; eutrofiering; adsorption; ICP; AutoAnalyzer;

    Sammanfattning : Det största hotet mot våra vattenmiljöer idag är eutrofieringen - överskottet av näringsämnen orsakat av avlopp och jordbruk. För att motverka detta krävs mer kunskap kring uppträdandet av fosfor i jord och, mer specifikt, fosforsorptionskapaciteten i sand- och grusjordar. LÄS MER

  5. 4. Synovial fluid components as synergistic lubricants in articular joint models

    Master-uppsats, KTH/Kemi

    Författare :Sixuan Li; [2019]
    Nyckelord :synergistic lubrication; synovial fluid; biolubrication; DPPC; hyaluronic acid; Mini-Traction Machine; macro- and microscale; profilometer;

    Sammanfattning : The excellent lubrication present within mammalian synovial joints attracted scientific interest, and some close-to-realistic models were applied to study the mechanism in vitro. In this project, the synergistic lubrication of synovial fluid was investigated by using 1,2-Dipalmitoyl-sn-glycero-3-phosphatidylcholine (DPPC), hyaluronic acid (HA), and phosphate-buffered saline (PBS buffer) to mimic the synovial fluid.

  7. 5. Adsorption of lysozyme on Silica Surfaces and Specific ion effects

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Guillem Onyos de Plandolit Ruiz; [2019]
    Nyckelord :Ellipsometry; mesoporous silica nanoparticles; surfaces; physical chemistry; fysikalisk kemi; Chemistry;

    Sammanfattning : Biomedical application of nanoparticles is largely associated to their fate in biological media which, in fact, is related to their surface properties. Surface functionalitzation plays a key role in determining biodegradation, cytotoxicity and biodistribution through interactions which may be meditated by the macromolecules occurring in biological media.
