  1. 1. Decarbonization of construction supply chains - Achieving net-zero carbon emissions in the supply chains linked to the construction of buildings and transport infrastructure

    Author : Ida Karlsson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Embodied carbon; Buildings; Emissions reduction; Transport infrastructure; Scenario analysis; Low carbon technology; Carbon abatement; Decarbonization; Construction; Supply chain; Carbon mitigation;

    Abstract : Sweden has committed to reducing greenhouse gas (GHG) emissions to a net-zero level by Year 2045. In Sweden, about 20% of its annual CO2 emissions are from the manufacture, transport and processing of materials for both the construction and refurbishment of buildings and transport infrastructure.

  2. 2. Lignin- and PAN-based carbon fibres as negative electrodes for alkali-ion batteries

    Author : Kevin Peuvot; Göran Lindbergh; Dan Zenkert; Enn Lust; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hard carbon; lithium-ion batteries; sodium-ion batteries; potassium-ion batteries; lignin-based carbon fibres; PAN-based carbon fibres; free-standing electrodes; Chemical Engineering; Kemiteknik;

    Abstract : The development of sodium-ion batteries (SIBs) and potassium-ion batteries (KIBs) have accelerated since they can now reach similar gravimetric energy densities as lithium-ion batteries (LIBs) but with a lower environmental impact. Hard carbon is the most common negative electrode for SIBs and KIBs and can be made from renewable resources such as lignin. READ MORE

  3. 3. Carbon Fibres and Carbonaceous Fillers in Engineering Thermosets

    Author : Björn Voigt; Chalmers University of Technology; []
    Keywords : melamine-formaldehyde; carbon black; phenol-formaldehyde; shungite; mechanical and electrical properties; carbon fibres;

    Abstract : In view of the excellent properties of carbon fibres (CF) and the growing demand for multi-functional materials e.g., electrically conductive composites, engineering thermosets with carbon fibres are highly attractive. Similarly, electrically conductive fillers are of great importance. READ MORE

  4. 4. Carbon-nanofibre-based tunable photonic crystals

    Author : Robert Rehammar; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transfer matrix; carbon nanofibre; fdtd; Photonic crystal; PECVD; plane wave expansion; tunable;

    Abstract : Photonic crystals are materials with periodically varying refractive indices. In conventional photonic crystal design it is hard to achieve tunable structures in the visible range. That is, structures with changeable optical properties. READ MORE

  5. 5. Tunable photonic crystals based on carbon nanofibers

    Author : Robert Rehammar; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; FDTD; PECVD; Photonic crystal; carbon nanofiber; tunable; diffraction; ellipsometry;

    Abstract : Photonic crystals are materials with periodically varying refractive indices. In conventional photonic crystal design it is hard to achieve tunable structures in the visible range, i.e. structures with changeable optical properties. READ MORE
