  2. 2. New Cu-I cluster compounds with luminescent properties

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Ehsan Jalilian; Sven Lidin; Torbjörn Gustafsson; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Copper I iodide; structure determination; luminescence; TDDFT; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Materials chemistry; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Materialkemi; materialkemi; Materials Chemistry;

    Abstract : The aim of this thesis has been to investigate how the synthesis route, choice of solvent and counter-ions effects the crystallization of Cu(I)I systems, and to investigate the correlation between the structure and luminescence properties of the systems.In order to do so a series of compounds based on an anion containing Cu(I)I, stabilized by organic cations have been produced.

  3. 3. Crystallization on the Mesoscale Self-Assembly of Iron Oxide Nanocubes into Mesocrystals

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Michael Agthe; Lennart Bergström; German Salazar-Alvarez; Tommy Nylander; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Self-assembly; iron oxide nanocubes; mesocrystal; small angle X-ray scattering; video microscopy; QCM-D; materialkemi; Materials Chemistry;

    Abstract : Self-assembly of nanoparticles is a promising route to form complex, nanostructured materials with functional properties. Nanoparticle assemblies characterized by a crystallographic alignment of the nanoparticles on the atomic scale, i.e. mesocrystals, are commonly found in nature with outstanding functional and mechanical properties.

  4. 4. Synthesis and modification of potential CO2 adsorbents Amine modified silica and calcium carbonates

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Baroz Aziz; Niklas Hedin; Lennart Bergström; Helmut Cölfen; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amine-modified silica; carbon capture; Fractional factorial design; IR spectroscopy; calcium carbonate; materialkemi; Materials Chemistry;

    Abstract : The prospect of rapid changes to the climate due to global warming is subject of public concern. The need to reduce the emissions of atmospheric green house gases and in particular carbon dioxide is greater than ever. Extensive research is performed to find new solutions and new materials, which tackles this problem in economically benign way. READ MORE

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

    Abstract : 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. READ MORE
