  1. 1. Characterization of Surfaces Relevant to Nanotechnology

    Author : Emelie Hilner; Lunds universitet.; Lund University.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanotechnology; surface science; semiconductors; scanning tunneling microscopy; spectroscopic photoemission and low energy electron microscopy; low energy electron diffraction;

    Abstract : In this thesis investigations of the structure and dynamics of semiconductor surfaces relevant for the synthesis of nanostructures are presented. The studies were performed using Scanning Tunneling Microscopy (STM), Low Energy Electron Diffraction (LEED), and Spectroscopic PhotoEmission and Low Energy Electron Microcopy (SPELEEM). READ MORE

  2. 2. Gold-Based Nanoparticles and Thin Films Applications to Green Nanotechnology

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Pia Lansåker; Uppsala universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; green nanotechnology; transparent conductors; nanoparticles; gold coalescence; substrate effect; temperature effect; Fysik; Physics;

    Abstract : The use of gold-based nanoparticles and thin films is very promising when it comes to improving several green nanotechnologies. Therefore, in order to further their use in applications such as electrochromic devices, photovoltaics, light-emitting diodes and photocatalysis, the aim of this work was to study the growth of gold-based nanoparticles and thin films.

  3. 3. The self-spreading double bilayer/Advances in lipid membrane nanotechnology

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Irep Gözen; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanotechnology; pore; lipid double bilayer; rupture; crackling noise; tension; self-spreading; vesicle; flat giant unilamellar vesicle; viscous fingering.;

    Abstract : In my thesis I describe the generation, characterization and uses of self-spreading double bilayers. This new type of solid-supported model membrane combines features and properties of the 2D lipid bilayer membrane, and the 3D phospholiposome. The double bilayer membrane, i.e. READ MORE

  4. 4. First As Probe, Then As Function - Fluorescence in Bio-inspired Nanotechnology

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jonas Hannestad; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; self-assembly; lipid membrane; bio-inspired; FRET; light-harvesting; spectroscopy.; fluorescence; nanotechnology; single molecule fluorescence spectroscopy; DNA;

    Abstract : In this thesis, I demonstrate how fluorescence can be used in the context of bio-inspired nanotechnology, both as an indirect probe and as a function in itself. By combining principles and molecules from three different bio-molecular systems, DNA, bacterial light-harvesting complexes and cell membranes, I have constructed nano- and microscale systems for long-range excitation energy transfer, light-harvesting and reaction control.

  5. 5. Fabrication and characterization of ZnO nanostructures for sensing and photonic device applications

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Syed M. Usman Ali; Linköpings universitet.; Linköpings universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanotechnology; zinc oxide; nanowires nanorods; nanotubes; nanoporous nanoflakes; electrochemical sensor and photonic devices;

    Abstract : Nanotechnology is an emerging inter-disciplinary paradigm which encompasses diverse fields of science and engineering converge at the nanoscale. This nanoscale science and nanostructure engineering have well demonstrated in the fabrication of sensors/transducers devices with faster response time and better sensitivity then the planer version of the sensor’s configurations.
