  1. 21. Rotational Diffusion of Cellulose Nanofibrils.

    University essay from KTH/Mekanik

    Author : Johan Wärnegård; William Hedén; [2014]
    Keywords : ;

    Abstract : Cellulose nanofibrils, CNF, is a technical term for the smallest crystalline constituents of wood. Namely particles of cylindrical shape measuring 20-40 nm in diameter and 1-2 um in length. These fibrils display high ultimate tensile strength and a Young's modulus comparable to Kevlar. READ MORE

  3. 22. Acoustic properties of porous materialsused in silencers

    University essay from KTH/Farkost och flyg

    Author : Jesper Kristoffersson; [2013]
    Keywords : ;

    Abstract : The aim of this master thesis is an experimental investigation of the acoustic characteristics of absorbing materials used in mufflers for trucks and cars. The difference in the composition between different wool type materials consists of difference in material, fibre diameter, length, density and fibre orientation. READ MORE

  5. 24. An Experimental Study of Fibre SuspensionFlows in Pipes using Nuclear MagneticResonance Imaging

    University essay from KTH/Mekanik

    Author : Masato Hirota; [2013]
    Keywords : Fibre suspension; Multi-phase flow; Nuclear magnetic resonance;

    Abstract : This study deals with fibre suspension flows through cylindrical pipes. Thepresent work aims at measurements of opaque flows, which are common inindustries. Nuclear magnetic resonance imaging (NMRI) and ultrasound velocimetryprofiling (UVP) were employed as non-invasive and optic-independenttools to measure the velocity profiles. READ MORE
