  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. Phase and Interface Design in Potential Earth-Abundant Multi-Component Photocatalysts

    L3-uppsats, Lunds universitet/Kemiska institutionen

    Författare :David Llorens Rauret; [2022]
    Nyckelord :Facet control; in-situ TEM; nanoparticle heterostructures; phase transformation; transition metal phosphides; inorganic nanomaterials; Chemistry;

    Sammanfattning : Transition metal phosphides are low-cost, earth-abundant semiconductors with promising properties for photocatalysis, including water-splitting. When combined with other semiconductors or noble metals in nanoparticles, their photocatalytic performance can be drastically enhanced. LÄS MER

  4. 3. Optimization of a one-part geopolymerization method for lab-scale, using waste glass wool as a precursor

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Oscar Enander; [2022]
    Nyckelord :Materials chemistry; Geopolymer; Glass wool; Recycling; Curing time; Curing temperature; Cement; Chemistry;

    Sammanfattning : Geopolymers are amorphous inorganic polymeric structures. They are used as binding agents and can be compared to cementitious materials such as ordinary Portland cement. This thesis aims to produce geopolymers from waste glass wool. Today glass wool is found in isolation, both thermal and sound insulation, and it is not being recycled. LÄS MER

  5. 4. The nutrient-color paradigm : A test based on a comperative analysis of lakes in four ecoregions in Sweden

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Viktoria Nordström; [2021]
    Nyckelord :;

    Sammanfattning : The nutrient-color paradigm explains lake productivity as a function of the concentrations of nutrients and colored dissolved organic matter (CDOM) in the water column.  Specifically, the paradigm predicts that primary production decreases with increasing concentrations of CDOM due to reduced light penetration, and increases with nitrogen or phosphorus concentration because these are typically the growth limiting elements for phytoplankton.

  7. 5. Study of the vibronic mixing in chlorophylls with multidimensional spectroscopy

    L3-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Ignacio Martínez Casasús; [2021]
    Nyckelord :Two-dimensional spectroscopy; Ultrafast spectroscopy; Chlorophyll a; Chlorophylls; Photosynthesis; Light harvesting; Vibronic mixing; Quantum coherence; Chemical physics; Chemistry;

    Sammanfattning : Chlorophylls comprise one of the most important families of molecules for the photosynthetic process. Chlorophyll-like molecules have been classically interpreted under the Gouterman model, being thought to feature two independent transitions, Qy(S1) and Qx(S2). LÄS MER
