  1. 1. Organic Electrode Battery Materials : A Journey from Quantum Mechanics to Artificial Intelligence

    Författare :Rodrigo P. Carvalho; Moyses Araujo; Daniel Brandell; Susanne Mirbt; Wolfgang Wenzel; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Batteries; Artificial Intelligence; Organic electrodes; High-voltage cathode materials; Machine learning; Materials discovery; High throughput screening; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : Batteries have become an irreplaceable technology in human life as society becomes progressively more dependent on electricity. The demand for novel battery technologies has increased fast, especially with the popularisation of different portable devices. LÄS MER

  2. 2. Organic Azides : Functional Molecules and Materials

    Författare :Giampiero Proietti; Peter Dinér; Per I. Arvidsson; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; perfluorinated Aromatic Azide; Photoactivatable; fluorophores; aggregation-induced emission; sulfonimidamides; sulfoximes; chiral auxilary; organogel; azides reduction; Ni-B; Kemi; Chemistry;

    Sammanfattning : The work presented in this thesis stems from the chemistry of the azido group, and more specifically from the unique reactivity of perfluorinated aromatic azides and how to use this reactivity to access new types of molecules to enable new applications in asymmetric synthesis and materials.In the first section of this thesis, a photoactivatable fluorescence probe is presented, where the non-luminescent azide was activated via a UV-light-promoted intramolecular N–H insertion reaction forming a fluorescence emitter.

    Sammanfattning : Porous materials have shown potential for solving one of the significant challenges to sequestering CO2 gas from point sources. Microporous materials, zeolites and metal-organic frameworks (MOFs) are porous materials with tailorable adsorptive properties to develop higher performance for an energy-efficient CO2 separation.

  5. 5. Sustainable porous organic materials : Synthesis, sorption properties and characterization

    Författare :Fredrik Björnerbäck; Niklas Hedin; Knut Irgum; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; porous materials; sorbents; microporous; CO2 capture and separation; gas adsorption; activated carbon; humins; hypercrosslinked polymers; sustainable; Materials Chemistry; materialkemi;

    Sammanfattning : The resources available to us humans, including metals, minerals, biomass, air, water, and anything else on the planet, are being used at an increasing rate. This anthropogenic use of resources both depletes the resources and has negative impacts on other resources, e.g. the biosphere. LÄS MER
