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

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Magnus Rahm; [2019]
    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.

  2. 2. In vitro characterization of nanodrugs at model lipid membranes

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Rickard Frost; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; in vitro screening; nanomedicine; drug delivery; drug carrier; supported lipid bilayer; QCM-D; nanoparticle; cell membrane;

    Abstract : The use of nano-sized drug carriers to improve the efficiency of drug delivery has become well established during the past decades. New nanoparticle (NP) formulations for the administration of biopharmaceuticals (e.g. proteins and peptides) emerge at an increasing rate and the need for methods to evaluate their properties is expanding.

  3. 3. Angle dependent light scattering of functional nanoparticle composites

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : JunXin Wang; Uppsala universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; light scattering; nano particle; absorption; radiative transfer; Solid State Physics; Fasta tillståndets fysik;

    Abstract : Varies functional nanoparticles play crucial roles in energy- and optical- related applications. The incorporation of functional nanoparticles into non-absorbing polymers to form optical absorption and scattering thin films have attracted considerable interest due to a successful selection of particles and matrices, synergistic effects of separation and fixation of particles, and controllable layer thicknesses and structures.

  4. 4. Characterization of Micro-Structures in Materials

    University dissertation from Göteborg : Chalmers University of Technology and University of Gothenburg

    Author : Henrike Häbel; Göteborgs universitet.; Gothenburg University.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Clustering; colloidal nanoparticle gels; image analysis; mass transport; point pattern; polymer blended films; pore shape;

    Abstract : On developing the next generation sustainable soft materials, it is often crucial to understand and control their properties and function. Whereas a characterization of three-dimensional data is desirable in corresponding studies, often two-dimensional data are less time consuming to obtain. READ MORE

  5. 5. Building Systems for Electronic Probing of Single Low Dimensional Nano-objects Application to Molecular Electronics and Defect Induced Graphene

    University dissertation from Uppsala : Acta Universitatis Upsaliensis
