  2. 1. Atoms in Lithiated Carbon Fibres

    Author : Marcus Johansen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lithium insertion; atom probe tomography; synchrotron hard X-ray photoelectron spectroscopy; energy storage; carbon fibres; Auger electron spectroscopy; microstructure; heteroatoms; multifunctional composites;

    Abstract : Carbon fibres are key constituents of structural batteries, in which electrochemical energy storage and mechanical load bearing are merged in one multifunctional device. Here carbon fibres simultaneously act as structural reinforcement by carrying load and as battery electrode by hosting lithium (Li)-ions in its microstructure. READ MORE

  4. 2. Surface tension-driven flow in soft porous materials — An investigation of the mechanism of capillary flow in microchannels of hydrogels

    Author : Johanna Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wetting on soft materials; Capillary flow; alginate gel; capillary action;

    Abstract : Spontaneous spreading of liquids in porous materials is of great industrial relevance and occurs in, for example, diapers, fabrics, paper or paint. Often, it is necessary to manipulate the spreading rate of liquids to result in the desired mass transport, for example to soak up large liquid volumes, as in a diaper. READ MORE

  5. 3. Resin transfer moulded composite materials : processing, structure, property relationships

    Author : J. Anders Holmberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : This thesis contains analysis of the performance of polymer composites manufactured by resin transfer moulding (RTM). The thesis consists of six papers, where the first two deals with the tensile strength of composites reinforced with randomly oriented glass fibres, which still is the most common reinforcement in RTM manufacturing.

  6. 4. Assessing design strategies for improved life cycle environmental performance of vehicles

    Author : Sofia Poulikidou; Anna Björklund; Per Wennhage; Gregory Keoleian; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle design; Design strategies; Lightweight design; Electric vehicles; Design for Environment DfE ; DfE tools; Life cycle assessment LCA ; Simplified LCA; Composite materials; Planering och beslutsanalys; Planning and Decision Analysis;

    Abstract : Vehicle manufactures have adopted different strategies for improving the environmental performance of their fleet including lightweight design and alternative drivetrains such as EVs. Both strategies reduce energy during use but may result in a relative increase of the impact during other stages. READ MORE

  7. 5. Thin Film and Plasma Characterization of PVD Oxides

    Author : Ludvig Landälv; Per Eklund; Emmanuelle Göthelid; Björn Alling; Lars Hultman; Erik Lewin; Linköpings universitet; []
