  1. 1. Coupling between iron and humic substances in a land-sea transitional zone in the northern Baltic Sea

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anna Osterman; [2023]
    Keywords : Iron; Humic substances; Dissolved organic carbon; Baltic Sea; Rivers;

    Abstract : In marine ecosystems around the world, iron (Fe) is a well-studied and important trace element which has been found to stimulate phytoplankton and cyanobacteria growth, as well as limit nitrogen fixation and being essential for Legionella pneumophila which is known as the main cause of Legionnaires’ disease. Fe also contributes to the brownification of freshwater and has recently been documented to increase in concentration in rivers in Sweden. READ MORE

  3. 2. Graphene Based Aqueous Ammonium Dual-Ion Batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Arvid Sandberg; [2023]
    Keywords : Dual ion batteries; materials science; chemistry; organic polymer;

    Abstract : The global transition to renewable energy sources is placing high demands on the development of effective energy storage methods, the most prevalent being batteries. Dual-ion batteries are a new battery technology that takes advantage of the simultaneous intercalation of both cations and anions. READ MORE

  4. 3. Effects of soil factors on pioneer bryophyte species composition

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Dora Mijić; [2023]
    Keywords : Biology and Life Sciences;

    Abstract : Bryophytes play a significant role in various ecological processes, including soil succession and colonization after disturbances. Although they are commonly believed to take up nutrients from soil solutions rather than the soil itself, the influence of soil on their growth and distribution is evident from previous studies.

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

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

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

    Abstract : 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. READ MORE

  6. 5. Biocatalysis in Pickering emulsions

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Christine Vera Isabel Schmidt; [2023]
    Keywords : Enzymes; Pickering emulsion; Amine Transaminases; Green Chemistry; Stereoselectivity; Biotechnology; Biology and Life Sciences;

    Abstract : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. READ MORE
