  3. 12. Designing multicomponent alloy coatings for corrosion protection

    Författare :León Zendejas Medina; Ulf Jansson; Leif Nyholm; Zoe Barber; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; corrosion; thin films; coatings; magnetron sputtering; high entropy alloy; percolation theory; mechanical tests; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : This thesis explores the design of metallic coatings for corrosion protection. The subject of the study was the new class of materials multicomponent alloys (MCAs, also known as high entropy alloys). They consist of near-equal concentrations of many (four or more) metals and are often reported to form a single phase with a simple crystal structure. LÄS MER

  4. 13. Energy Transfer Processes and Quenching Pathways in Lanthanide Complexes: The Role of Structural Changes

    Författare :Daniel Kocsi; K. Eszter Borbas; Raphaël Tripier; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lanthanide; luminescence; sensitisation; quenching; electron transfer; organic chromophores; fluorination; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Sammanfattning : Due to their unique magnetic and luminescent properties, trivalent lanthanides (Ln(III)) have been widely utilised in cellular imaging. Ln(III) luminescence is usually sensitized by a light-harvesting ‘antenna’, a chromophore that can transfer the excitation energy to the Ln(III). LÄS MER

  5. 14. Highly Concentrated Electrolytes for Rechargeable Lithium Batteries

    Författare :Viktor Nilsson; Kristina Edström; Patrik Johansson; Reza Younesi; Serena Corr; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li-ion battery; SEI; Highly concentrated electrolyte; Al dissolution; Li metal battery; ion transport; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : The electrolyte is a crucial part of any lithium battery, strongly affecting longevity and safety. It has to survive rather severe conditions, not the least at the electrode/electrolyte interfaces. LÄS MER

  7. 15. Conducting Redox Polymers for Electrode Materials : Synthetic Strategies and Electrochemical Properties
