  2. 1. Modeling colloidal nanoparticles: From growth to deposition

    Author : Joakim Löfgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gold; DLVO; thermodynamics; van der Waals; density functional theory; modeling; deposition; dispersive interactions; anisotropic; colloidal nanoparticles; nanorods;

    Abstract : In recent decades metal nanoparticles (NPs) have been the subject of intense research. The interest stems from the NPs physicochemical properties that can be conveniently tuned through, e.g., their size, shape or composition. READ MORE

  4. 2. Particle Deposition Studies in a Laminar Wall Jet - The Hydrodynamic Influence on the Kinetics of Colloidal Deposition

    Author : Anders Göransson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shielding function; surface blocking; total internal reflection microscopy; laminar wall jet; random sequential adsorption; colloidal deposition; Food and drink technology; Livsmedelsteknik;

    Abstract : In the research area of cleaning and process hygiene it is important to understand the underlying mechanisms behind the deposition of particles and macromolecules onto surfaces. The deposition process is described as the transport of particles to the surface followed by attachment. READ MORE

  5. 3. Synthesis, Electrophoretic Deposition, and Characterization of Nanostructured Thermoelectric Materials

    Author : Hazal Batili; Muhammet Toprak; Oliver Fenwick; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Thermoelectric; Bismuth telluride; Antimony telluride; Hydrothermal synthesis; Thermolysis; Polyol; Electrophoretic deposition; EPD; Seebeck coefficient; Thermoelectric power factor; Colloidal stabilization; Material and Nano Physics; Material- och nanofysik;

    Abstract : The world’s increasing demand for energy and supplying this energy dominantlyfrom fossil fuels has a major impact on global climate change. Theenergy crisis has gotten more alarming in the recent years which increasedthe motivation for replacing fossil fuels with greener routes for energy harvest. READ MORE

  6. 4. Mesoporous Silica SBA-15 - Formation, Modification and Application

    Author : Tomas Kjellman; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SBA-15; Mesoporous Silica; Intrawall pores; Colloidal Stability; Drug release; Deposition;

    Abstract : Several aspects related to the mesoporous silica material SBA-15 have been studied through the use of a wide range of experimental techniques, including low voltage high-resolution scanning electron microscopy, small angle X-ray scattering and nitrogen sorption. This work contains three parts, which are in many ways overlapping. READ MORE

  7. 5. Optical properties of nanometer disks, holes and rings prepared by colloidal lithography

    Author : Per Hanarp; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; colloidal lithography; nanoparticles; nanorings; localized surface plasmon resonance; electrostatic self-assembly; nanofabrication; sub-wavelength holes;

    Abstract : The optical properties of nanostructures prepared by colloidal lithography are studied. Colloidal lithography is a fabrication approach based on a self-assembling pattern definition. An electrostatically self-assembled array of nanoparticles is used as a mask and combined with etching or deposition processes. READ MORE
