  1. 1. Functional PVC Additives : Core-Shell Nanoparticle and Renewable Resource Plasticizers

    Författare :Bo Yin; Minna Hakkarainen; Mikael Skrifvars; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PVC; nanocomposite; nanoparticle; core-shell; plasticizer; renewable resources; isosorbide; glucose;

    Sammanfattning : Several functional poly(vinyl chloride) (PVC) additives were designed: PVC plasticizers made from renewable resources as alternatives to traditional phthalate plasticizers and core-shell nanoparticle-plasticizers with the aim to design an additive that can improve several mechanical properties simultaneously. Monomeric and oligomeric PVC plasticizers based of isosorbide and glucose were synthesized. LÄS MER

  4. 3. Aerosol Generated Core-shell Nanoparticles : Synthesis and Characterization

    Författare :Markus Snellman; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aerosol technology; core-shell particles; nanoparticles; Janus particles;

    Sammanfattning : Aerosol technology is a promising platform to synthesize and study core-shellnanoparticles - a multi-elemental nanoparticle system where the core of one material is covered by a shell of another material. In this thesis, two distinctly separate strategies have been explored to synthesize core-shell nanoparticles by aerosol methods: physical vapor deposition (PVD) by evaporation, and surface segregation via thermal treatment.

  5. 4. Strain and Charge Transport in InAsP-InP and InP-InAs Core-Shell Nanowires

    Författare :David Göransson; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanowire; InAsP-InP core-shell nanowire; InP-InAs core-shell nanowire; strain; XRD; charge transport; Coulomb blockade; Josephson junction; Fysicumarkivet A:2019:Göransson;

    Sammanfattning : The mechanical, optical, and electrical properties of III-V semiconductor heterostructures are investigated in thisthesis. The semiconductor materials are grown by metal-organic vapor phase epitaxy, yielding wire shaped crystals(nanowires) having a length of ~ 1 μm and diameter of ~ 100 nm. LÄS MER

  7. 5. Three-body systems in the no-core shell model

    Författare :DANIEL SÄÄF; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; core swelling; halo nuclei; no-core shell model; nuclear physics; clusterization;

    Sammanfattning : In this thesis we present the ab initio no-core shell model (NCSM) and we use that framework to study 6He and 6Li computed with a realistic nucleon- nucleon interaction. In particular, we present results for the point-proton radius and the ground-state energy. LÄS MER
