  1. 11. Formation of Soft Particles in Drop-in Fuels

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Richard Abdel Alim; [2018]
    Nyckelord :;

    Sammanfattning : As the mission to the decrease global warming and phase out highly pollutingenvironmental practices globally, regulations including Euro 6 and policies generated by theUnited Nations Framework Convention on Climate Change (UNFCCC) are pushing companiesto be more innovative when it comes to their energy sources. These regulations involve manyfactors related to the cleanliness of the fuel and produced emissions, for example, propertiesof the fuels such as sulfur content, ash content, water content, and resulting emission valuesof Carbon dioxide (CO2) and Nitrogen Oxides (NOx).

  3. 12. Optical durability of reflector materials for solar energy applications

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Josefine Nilsson; [2018]
    Nyckelord :;

    Sammanfattning : In line with The Paris Agreement, the world is now changing towards more sustainable options for all sorts of energy development. The solar energy sector is growing rapidly as a result of this. One area that holds great potential in changing many of the worlds heating processes, is concentrating solar power (CSP). LÄS MER

  4. 13. Physical and Mechanical Properties of Medite® MDF Exterior from Acetylated Wood Fibers

    Master-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Junqiu Li; [2018]
    Nyckelord :Medite® MDF exterior; Medium density fibreboard MDF ; Acetylated wood fibers; Physical properties;

    Sammanfattning : Currently, the demand for wood-based panels has been growing solidly in European countries. Medium density fibreboard (MDF) manifests the potentialities for outstanding physical and mechanical properties. However, MDF from different fiber sources is normally designed for internal applications due to the poor moisture resistant capability. LÄS MER

  5. 14. Enhancing the durability of fluorocarbon-free Durable Water Repellant (DWR) formulation

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Meron Solomon; [2017]
    Nyckelord :Hydrophobicity; textile coating; cross-linker; nanoparticles; surface roughness;

    Sammanfattning : The focus of the project was to alter and optimize the water repellant textile coating formulations to reach enhanced durability. For this purpose, the project was approached with three methods. Firstly, bio-based components were implemented in the mother emulsion to act as surfactant and crosslinking agent and to provide hydrophobic properties. LÄS MER

  7. 15. Project ABSS : Adhesive bonding of stainless steels

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Viktor Andersson; Andreas Larsson; [2017]
    Nyckelord :Adhesive; Tejp; Bonding; Stainless steels; Accelerated aging; Tensile test; Watertightness test;

    Sammanfattning : This report aims to increase the scientific knowledge about long-term prospects for the adhesive and adhesive joints for bonding of stainless steels. The effects of water, temperature and chemicals on the adhesive and adhesive joints are investigated. LÄS MER
