  1. 16. Study of Improved Sampling and Preparation of East-Swedish Glacial Clay

    University essay from KTH/Jord- och bergmekanik

    Author : CLARA GARCIA DE HERREROS; [2020]
    Keywords : clay; disturbance; sample quality; block sampling; preconsolidation pressure; shear strength.;

    Abstract : The aim of this study is to determine if the mini block sampling technique couldoffer a complement to the Swedish standard StII piston sampler for achieving higherquality samples. The principle is that having a greater diameter the sample is meticulouslytrimmed to the usual geometry, so that the periphery of the sample is not disturbedby the sampling procedure and the same testing equipment can be employed.

  3. 17. Analysis of length effect dependencies in tensile test for paperboard

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Filip Claesson; [2020]
    Keywords : paperboard; short span;

    Abstract : Paperboard combined with polymer and aluminium films are widely used in food packages. Paperboard is used for the bulk of the package material, and provides the stiffness. Paperboard is a highly anisotropic material, which is affected by how the fibers are orientated. READ MORE

  4. 18. Multifunctional Wood Polymer Composites Reinforced with Graphene Nanoplatelets : Investigating if multifunctionality can be achieved in wood polymer composites through the addition of graphene nanoplatelets

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Vanessa Meulenberg; [2019]
    Keywords : Wood polymer composites; graphene; multifunctional; wood flour;

    Abstract : Graphene nanoplatelets (GNPs) were used to reinforce wood polymer composites (WPCs) in order to achieve multifunctionality. Multifunctionality could be achieved through the GNPs because of their excellent mechanical and electrical properties. The research consists of two parts: HDPE/GNP/WF composites and LLDPE/GNP composites. READ MORE

  5. 19. Non-destructive Evaluation of Ultrasound Contrast Agent

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Wendi Löffler; [2019]
    Keywords : ultrasound; microbubbles; contrast agent; attenuation; phase velocity;

    Abstract : Clinical ultrasound imaging techniques can be greatly improved by the use of ultrasound contrast agents (UCAs). While microbubbles (MBs) without shell are unstable and cannot be used for practical applications,a shell produced from biocompatible polyvinylalcohol (PVA) significantly improves chemical versatility and stability.

  6. 20. Phase stability and mechanical properties of M4AlB4 (m=Cr, Hf, Mo, Nb, Ta, Ti, V, W, Zr) from first principles

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Adam Carlsson; [2019]
    Keywords : MAB phase Cr4AlB4 Stability dynamical thermodynamical mechanical;

    Abstract : The recent discovery of Cr4AlB4, a laminated ternary metal boride belonging to the family of layered MAB-phases, where the transition metal boride layers are interleaved by an A layer, has spurred theoretical investigation for novel M4AlB4 phases. In this study, first-principles calculations were applied in order to investigate the thermodynamical stability and mechanical properties of M4AB4 where M = Cr, Hf, Mo, Nb, Ta, Ti, V, W, Zr while the A layer was kept fixed as Al.
