  1. 1. Perspectives on low carbon lifestyles

    Författare :David Andersson; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; GHG emissions; climate change; satisfaction with travel scale; sustainable consumption; materialistic values; air travel; rebound effect.; congestion charge; households; subjective well-being;

    Sammanfattning : Climate change is one of the most severe problems facing the world today. If extensive measures are not undertaken to reduce greenhouse gas (GHG) emissions within the near future, the natural conditions under which life depends will change for the worse (Pachauri et al, 2014).

    Sammanfattning : This thesis is about whether it is a good idea to place monetary value on nature, to remedy the fact that we treat it as having no particular value to us humans, although it clearly has. The thesis is based on five research papers that can be said to position themselves on opposite sides in the debate on monetisation of nature. LÄS MER

  4. 3. Low Temperature Austenite Decomposition in Carbon Steels

    Författare :Albin Stormvinter; Annika Borgenstam; John Ågren; Peter Hedström; John G. Speer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon steels; Electron backscattered diffraction; Martensite; Microscopy; Microstructure; Thermodynamic modeling;

    Sammanfattning : Martensitic steels have become very important engineering materials in modern society. Crucial parts of everyday products are made of martensitic steels, from surgical needles and razor blades to car components and large-scale excavators. LÄS MER

  5. 4. Biobased carbon fibers from solution spun lignocellulosic precursors

    Författare :Andreas Bengtsson; Monica Ek; Maria Sedin; Elisabet Brännvall; Elisabeth Sjöholm; Johannes Ganster; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Carbon fiber; Carbonization; Cellulose; Kraft pulp; Softwood kraft lignin; Solution spinning; Stabilization; Barrvedslignin; Cellulosa; Karbonisering; Kolfiber; Lösningsmedelsspinning; Stabilisering; Sulfatmassa; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Carbon fibers (CFs) have excellent mechanical properties and a low density, making themattractive as a reinforcing fiber in composites. The use of CFs is limited to high-end applications,since they are produced from an expensive fossil-based precursor via an energy-intensivemanufacturing process, explaining the need for cheaper CFs from renewables.

  7. 5. Carbon Nanotube Polymer Composites: Mechanical, Electrical and Photorefractive Properties

    Författare :Liliana Licea Jimenez; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes; electrical properties; photorefractive properties.; polymer matrix nanocomposites; mechanical properties;

    Sammanfattning : Incorporation of carbon nanotubes (CNT) into polymers is attractive due to the generally good processability of polymers and unprecedented properties of nanotubes. In this work, preparation and matrix known earlier but not employed so-far for nanocomposites are studied towards enhanced mechanical and electrical performances. LÄS MER
