  1. 21. Covalent functionalization of carbon nanomaterials for bioelectrochemical applications

    Author : Naoual Allali; Alexander Soldatov; Manuel Dossot; Victor Mamane; Silvia Giordani; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Abstract : Carbon nanotubes (CTNs) are renowned for their exceptional electronic and mechanical properties. Their structure can be considered as rolling up a graphene sheet along a specific crystallographic direction, leading to a 1D confinement of the electronic wavefunction of the delocalized electrons along the perimeter of the cylindrical structure thus obtained.

  2. 22. lnterfacial Design and Characterization of Oligo(ethylene glycol) Self-Assembled Monolayers : Templates for Biomolecular Architectures

    Author : Ramūnas Valiokas; Stephen D. Evans; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis presents efforts to better understand and control the interfacial properties of oligo(ethylene glycol)-containing self-assembled monolayers (OEG SAMs) on gold. This has been done by means of molecular and interfacial design, followed by extensive characterization of the SAMs using a variety of surface analytical techniques. READ MORE

  3. 23. Optics of Conducting Polymer Thin Films and Nanostructures

    Author : Shangzhi Chen; Magnus Jonsson; Vanya Darakchieva; William Barnes; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Intrinsically conducting polymers forms a category of doped conjugated polymers that can conduct electricity. Since their discovery in the late 1970s, they have been widely applied in many fields, ranging from optoelectronic devices to biosensors. The most common type of conducting polymers is poly(3,4-ethylenedioxythiophene), or PEDOT. READ MORE

    Abstract : The aim of this thesis work was to gain understanding of the interactions between talc mineral and surfaces, liquids and chemicals relevant for industrial applications, such as pulp and paper. Talc is used in the pulp and paper industry as a filler pigment, in control of pitch (lipophilic extractives) deposits and as a coating pigment. READ MORE

  5. 25. Structural and elastic properties of InN and InAlN with different surface orientations and doping

    Author : Mengyao Xie; Vanya Darakchieva; Jens Birch; Enrique Calleja; Linköpings universitet; []
    Keywords : ;

    Abstract : Group–III nitrides, InN, GaN, AlN, and their alloys, have revolutionized solid state lighting and continue to attract substantial research interest due to their unique properties and importance for optoelectronics and electronics. Among the group–III nitrides, InN has the lowest effective electron mass and the highest electron mobility, which makes it suitable for high–frequency and high power devices. READ MORE
