  2. 1. A spectroscopic study of polymer : Carbon nanotube composites

    Author : Andreas Müller; Ove Andersson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : Since the identification of carbon nanotubes (CNTs) by Ijima in 1991, this material has become a subject of great interest and effort in science because of the outstanding physical properties it exhibits. CNTs can be thought of as graphene sheets rolled into seamless cylinders of various diameters and in principle infinite length. READ MORE

  4. 2. Development of laser spectroscopy for scattering media applications

    Author : Mats Andersson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laserteknik; Laser technology; Atom- och molekylärfysik; Atomic and molecular physics; Fysik; Physics; coherent sampling; optical sensor; light absorption; noninvasive measurement; diode laser; scattering of light; laser spectroscopy; fluorescence spectroscopy; remote sensing; Lidar; DIAL;

    Abstract : Laser spectroscopy for both large and small spatial scales has been developed and used in various applications ranging from remote monitoring of atmospheric mercury in Spain to investigation of oxygen contents in wood, human sinuses, fruit, and pharmaceutical solids. Historically, the lidar group in Lund has performed many differential absorption lidar (DIAL) measurements with a mobile lidar system that was first described in 1987. READ MORE

  5. 3. Self-assembly of magnetic particles

    Author : Hauke Carstensen; Max Wolff; Vassilios Kapaklis; Björgvin Hjörvarsson; Benjamin Yellen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; self-assembly; tunable interactions; phase transition; ferrofluid; Fysik; Physics;

    Abstract : Self-assembly is the spontaneous formation of larger structures from small building blocks. This process is driven and determined by the interactions between the constituents. READ MORE

  6. 4. First Principles Studies on Chemical and Electronic Structures of Adsorbates

    Author : Wenhua Zhang; Yi Luo; Gianfranco Pacchioni; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Solid state chemistry; Fasta tillståndets kemi; Computational physics; Beräkningsfysik; Surfaces and interfaces; Ytor och mellanytor;

    Abstract : In this thesis, we focus on theoretical study of adsorbates on metal and oxide surfaces that are important for surface chemistry and catalysis. Based on first principles calculations, the adsorption ofCO, NO, NO2, C4H6S2, C22H27SH and other molecules or radicals on nobel metal surfaces (gold and silver) are investigated. READ MORE

  7. 5. In-situ TEM Probing of Nanomaterials

    Author : Magnus Hummelgård; Håkan Olin; Valeria Nicolosi; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanotechnology; in situ; TEM; probing; nanowires; nanoparticles; ink; Other engineering physics; Övrig teknisk fysik; Material physics with surface physics; Materialfysik med ytfysik; Condensed matter physics; Kondenserade materiens fysik;

    Abstract : Nanomaterials because of their small size, may have special properties unlikely to be seen in ordinary types of materials. Nanomaterials like nanotubes,nanowires and nanoparticles are best studied at the nanoscale, vital but also problematic. READ MORE
