  1. 1. Transition metal dissolution from Li-ion battery cathodes

    Författare :Yonas Tesfamhret; Reza Younesi; Erik J. Berg; Mark Huijben; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion battery; Lithium-ion cathode; Transition metal dissolution; Atomic Layer Deposition; Inductively coupled plasma atomic emission spectroscopy; Cathode-electrolyte interaction; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : Lithium-ion batteries (LIBs) have become reliable electrochemical energy storage systems due to their relative high energy and power density, in comparison to alternative battery chemistries. The energy density of current LIBs is limited by the average operating voltage and capacity of oxide-based cathode materials containing a variety of transition metals (TM). LÄS MER

  3. 2. Molecular studies of initial atmospheric corrosion of copper : Exploration of ultra-sensitive techniques for the inhibiting effect of self assembled monolayers, and the effect of gamma radiation

    Författare :Saman Hosseinpour; Christofer Leygraf; Franz Geiger; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Corrosion; copper; self assembled monolayer; sum frequency spectroscopy; qcm; gamma radiation;

    Sammanfattning : Atmospheric corrosion indoors is of great practical importance for the degradation of metals, for example in electronics, military equipment, and cultural heritage items. It involves a wide range of chemical, electrochemical, and physical processes occurring in gas, liquid, and solid phases, and at the interfaces between them. LÄS MER

  4. 3. Cation adsorption properties of substituted kraft fibres : an experimental and thermodynamic modelling study

    Författare :Ola Sundman; Lars-Olof Öhman; Per Persson; Janne Laine; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kraft fibres; Donnan equilibria; ion exchange; acid base properties; potentiometric titrations; thermodynamic modelling; NPEs; GaAl12 7 ; EXAFS; Chemistry; Kemi;

    Sammanfattning : Acid/base and metal ion adsorption properties have been investigated for a range of chemically modified bleached Kraft fibre materials (pulps). The studies were performed via potentiometric titrations, Flame Atomic Absorbtion (and Emission) Spectroscopy, Inductively Coupled Plasma Optical Emission Spectroscopy and Extended X-ray Absorbtion Fine Structure measurements.

  5. 4. Selective Comminution Applied to Mineral Processing of Critical Metals

    Författare :Lorena Guldris Leon; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; selective comminution; compressive crushing; analytical method; minerals; critical metals; elements.;

    Sammanfattning : The outstanding properties of tungsten and tantalum make them valuable metals and, in some cases, irreplaceable in applications. Due to the vital economic importance and limited supply, growing interest places these metals on the critical metals risk list. LÄS MER

  7. 5. Melanogenesis as the basis for melanoma targeting

    Författare :Ulla Mårs; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Toxicology; toxikologi;

    Sammanfattning : The incidence of malignant melanoma has increased rapidly during the last decades, and the prognosis for disseminated melanoma is poor. The melanoma cells produce melanin, and therefore the melanogenesis may serve as a target for treatment of melanotic melanoma; thioureyelenes such as thiourea and 2-thiouracil, e.g. LÄS MER
