  2. 6. The Influence of Dopants on the Growth of Diamond by CVD

    Author : Tanguy Van Regemorter; Karin Larsson; Matthias Schreck; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diamond; growth; chemical vapour deposition; nitrogen; phosphorus; boron; sulphur; density functional theory; Materials chemistry; Materialkemi;

    Abstract : Diamond is an important material in many industrial applications (e.g., machining of hard materials, bio-electronics, optics, electronics, etc.) because of its exceptional properties such as hardness, tolerance to aggressive environments, compatibility with human tissues, and high carrier mobility.

  4. 7. In Light of Ionic Materials : A short exploration of ionic materials for light-related applications

    Author : Brando Adranno; Anja-Verena Mudring; Annegret Stark; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ionic materials; ionic liquids; mesophases; light-emission; electrochemical applications; materialkemi; Materials Chemistry;

    Abstract : Ionic liquids (ILs) have been one of the most attractive classes of materials of the last decades. The reason behind this is their peculiar set of properties, which enable their possible application in several research fields. ILs are salts that exhibit a very low melting point, which has been arbitrarily defined to be below 100 °C. READ MORE

  5. 8. Crystallization on the Mesoscale : Self-Assembly of Iron Oxide Nanocubes into Mesocrystals

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

    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.

  6. 9. Thermal Conductivity of Hygroscopic Foams Based on Cellulose Nanomaterials

    Author : Varvara Apostolopoulou-Kalkavoura; Lennart Bergström; Tatiana Budtova; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; thermal conductivity; cellulose nanomaterials; foams; hygroscopic; super-insulating; phonon scattering; moisture uptake; heat transport; Materials Chemistry; materialkemi;

    Abstract : Biobased super-insulating materials could mitigate climate change by minimizing the use of petroleum-based materials, creating artificial carbon sinks and minimizing the energy needed to maintain pleasant interior conditions. Cellulose nanomaterials (CNM) produced from abundantly available cellulose sources constitute versatile, highly anisotropic raw materials with tunable surface chemistry and high strength. READ MORE

  7. 10. Synthesis and modification of potential CO2 adsorbents : Amine modified silica and calcium carbonates

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

    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
