  1. 21. Design, synthesis and evaluation of bacterial sialic acid uptake inhibitors

    Författare :Tiago Bozzola; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sialic Acid; antibacterial agents; Medicinal Chemistry; Synthesis; uptake inhibitors;

    Sammanfattning : Antibiotic resistance is a major threat for our society and finding novel antibacterial therapies is of greatimportance. In this thesis, we investigate bacterial sialic acid uptake inhibitors as a novel antibacterial approach.Bacteria do not biosynthesise sialic acid and therefore harvest it from the host. LÄS MER

  3. 22. The use of Fenton chemistry for reducing the refining energy during TMP production : the effect of free ferrous and free or chelated ferric ions

    Författare :Karin Walter; Per Engstrand; Magnus Paulsson; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The potential of using acid hydrogen peroxide under Fenton conditions to lowerthe electrical energy consumed during the production of Black spruce (Piceamariana) thermomechanical pulp (TMP) was investigated in pilot scale. Thechemical system, which consisted of ferrous sulphate, hydrogen peroxide andoptionally an enhancer (such as a chelating agent), was evaluated as an inter-stagetreatment. LÄS MER

    Författare :Fabian Jeschull; Daniel Brandell; Bernard Lestriez; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; binder; CMC-Na; PAA; graphite; silicon; lithium-ion battery; photoelectron spectros-copy; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Sammanfattning : We are today experiencing an increasing demand for high energy density storage devices like the lithium-ion battery for applications in portable electronic devices, electric vehicles (EV) and as interim storage for renewable energy. High capacity retention and long cycle life are prerequisites, particularly for the EV market. LÄS MER

  5. 24. Observations on essential biochemical data profile in connection with restorative proctocolectomy in humans : vitamin B12 and fat absorption cited

    Författare :Amosy Ephreim M'Koma; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : PATIENTS: The material includes 99 patients who consecutively received handsawn pouch and ileoanal anastomosis, after mucosectomy. Sixty-five patients were men and forty-four were women. The mean-age was 31.4 (range 17-59) years. LÄS MER

  7. 25. Innovative process solutions towards recycling of salt cake from secondary aluminum smelting

    Författare :Peng Li; Lidong Teng; Sankaran Subramanian; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal diffusivity; Model; Solubility; CO2; AlN; Crystals; Hydrolysis; Enhance; Hinder; Leaching; Absorption; Synthesis; SiMgAlON; Oxidation; Arctan; Activation energy; Mullite; Liquid; Crystallization.; SRA - Production; SRA - Produktion;

    Sammanfattning : To offer better solutions for the recycling of salt cake from secondary aluminum melting, several innovative investigations were carried out based on hydrometallurgical and pyrometallurgical views.Thermal diffusivity measurements as a function of temperature on salts-Al composites having various compositions (0, 2, 4, 6, 8, 10, 12wt pct metallic Al) were carried out.
