  2. 11. Ceria Nanoparticle Hybrid Materials : Interfacial Design and Structure Control

    Author : Eric Johansson Salazar-Sandoval; Mats Johansson; Wolfgang Bremser; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This doctoral thesis addresses the challenge of bringing two very different materials into intimate chemical contact: inorganic metal oxide nanoparticles and acrylic polymers. In order to achieve this ambitious goal, the work has been divided into a series of more accessible tasks. READ MORE

  4. 12. Single Copper Nanoparticle Oxidation

    Author : Sara Nilsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dark-field scattering spectroscopy; single particle; plasmonic nanospectroscopy; plasmonic sensing; transmission electron microscopy; oxidation; nanoscale Kirkendall effect;

    Abstract : Cu nanoparticles are commonly used in microelectronic devices and as catalysts in, for example, methanol synthesis and methanol steam reforming reactions. However, Cu nanoparticles are prone to oxidation. READ MORE

  5. 13. Structure and chemical ordering in metallic nanoparticles from atomic scale modeling

    Author : Magnus Rahm; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; regular truncated octahedron; chemical ordering; nanoparticle shapes; molecular dynamics; icosahedron; Monte Carlo; modeling; Marks decahedron; nanoparticle structures;

    Abstract : In the last decades, a wide range of attractive properties have put metallic nanoparticles in the spotlight. These properties, often related to optical response and catalytic performance, are to a large extent dependent on structure and chemical ordering, that is, the distribution of elements in the nanoparticle.

  6. 14. Organization of Nanoparticles in Solution-A TEM Study

    Author : Olivier Balmes; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materiallära; materialteknik; Material technology; organisation; plunge freezing; TEM; nanoparticle; transmission electron microscopy;

    Abstract : A new approach to the study of nanoparticle systems has been introduced. Nanoparticle systems in aqueous and organic solutions have been synthesized and studied by transmission electron microscopy. These systems include nanoparticles of gold, silver, palladium, ruthenium, and platinum which have been stabilized using various ligands. READ MORE

  7. 15. De Novo Design and Characterization of Surface Binding Peptides - Steps toward Functional Surfaces

    Author : Patrik Nygren; Bengt-Harald Jonsson; Klas Broo; Linda Andersson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peptide; design; nanoparticle; CD; Amino acid; Organic chemistry; Organisk kemi;

    Abstract : The ability to create surfaces with well-defined chemical properties is a major research field. One possibility to do this is to design peptides that bind with a specific secondary structure to silica nanoparticles. READ MORE
