  2. 1. Biocomposites Based on Core-Shell Cellulose Nanofibers : Preparation, Structure, and Properties

    Author : Kasinee Prakobna; Lars Berglund; David Plackett; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; cellulose nanofibers; polysaccharides; holocellulose; nanostructure; dispersion; mechanical properties; hygromechanical properties; moisture stability; film; porous material; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Cellulose nanofibers (CNFs) are of interest as load-bearing components for polymer matrix nanocomposites. A wide range of nanostructured materials including nanopaper/films, foams, aerogels, and hydrogels can be prepared from CNFs. The material performance can be fine-tuned when CNFs are combined with different polymer matrices. READ MORE

    Abstract : 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. READ MORE

  6. 4. Computer Simulations of Polymer Gels : Structure, Dynamics, and Deformation

    Author : Natasha Kamerlin; Christer Elvingson; Jan Forsman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer simulations; Brownian dynamics; polymer gel; microgel; spherical boundary conditions; hypersphere; core-shell; deswelling; mechanical properties; uniaxial elongation;

    Abstract : This thesis presents the results of computer simulation studies of the structure, dynamics, and deformation of cross-linked polymer gels. Obtaining a fundamental understanding of the interrelation between the detailed structure and the properties of polymer gels is a challenge and a key issue towards designing materials for specific purposes.

    Abstract : In this Thesis experimental studies of nano-clusters using synchrotron radiation based photoelectron (UPS and XPS) and Auger Electron Spectroscopy (AES) are presented. The investigations may be divided into two parts where the first reports on the structure of heterogeneous two component clusters, and the second concerns electronic decay processes. READ MORE
