1. 1. The effect of different recovered fibres on mechanical properties of board

   University essay from Karlstads universitet/Avdelningen för kemiteknik

   Author : Syed Ali Hassnain Shah; [2012]
   Keywords : Z-strength; mechanical properties; bending stiffness; couching method; recovered fibres; 4-ply board;

   Abstract : The objective of this work was to determine the influence of recovered fibres on the mechanical properties of board. Industrial board was provided by Fiskeby Board AB and laboratory board was made by using an isotropic sheet former. Board properties such as tensile strength, tensile stiffness, z-strength and bending stiffness were evaluated. READ MORE

3. 2. Fibre-to-Board - Validation of the Simulation Model and Development of Laboratory Methods to Receive Input Data

   University essay from Fakulteten för teknik- och naturvetenskap

   Author : Charlotta Boström; Anna Rosén; [2006]
   Keywords : shrinkage; free drying; restrained drying; Fibre-to-Board; hand sheet properties; fine material; tensile stiffness; simulation;

   Abstract : Fibre-to-board is a simulation model developed at Stora Enso Research Centre Karlstad. Within this model isotropic hand sheet properties are used as input data for prediction of the final multi ply board properties. READ MORE

4. 3. Pelletering av tallspån : grundläggande studier

   University essay from SLU/Dept. of Silviculture

   Author : Dan Bergström; [2005]
   Keywords : pelletering; biobränsle; tallspån; tryckhållfasthet; densitet; presstryck; presstemperatur;

   Abstract : Wood pellets are an upgraded product of residuals from several wood processing industries, for example saw mills and pulp industries. The pellets are produced by pressing the milled and dried sawdust to cylindrical units with a higher density than the initial raw material. READ MORE

5. 4. Plant Extract Sensitised Nanoporous TiO2 Thin Film Photoelectrochemical Cells

   University essay from Institutionen för geovetenskaper

   Author : Sigrid Hedbor; Linnéa Klar; [2005]
   Keywords : photoelectrochemical cell; solar cell; nanoporous; thin film; titanium dioxide; dye sensitised; ruthenium; plant extract; beetroot.;

   Abstract : För att undersöka skillnad i prestationsförmåga mellan celler sensiterade med växtextraktsbaserad färg, och celler sensiterademed ruteniumkomplex-baserad färg, samt huruvida presskraften påverkar en cells prestationsförmåga, tillverkades icke-slutna fotoelektrokemiska färg-sensiterade solceller med tunnfilmsfotoelektroder av pressad, nanoporös titandioxid. Cellerna pressades med tre olika presskrafter och sensiterades med växtextraktsfärg från rödkål, rödbeta, viol och henna, samt en ruteniumkomplex-baserad färg som fick utgöra kontrollbetingelse.
