  1. 1. Material characterisation for crash modelling of composites

    Author : Thomas Bru; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical testing; finite element analysis FEA ; non-crimp fabric NCF ; damage mechanics; carbon fibre composite; crushing;

    Abstract : The transport industry must find solutions to reduce its impact on climate change. A promising way to reduce the weight of vehicles and therefore to reduce the CO2 emissions is to introduce components made of lightweight composite materials, in particular carbon fibre reinforced plastics (CFRPs).

  2. 2. Structural and Electrochemical Properties of Functionalized Nanocellulose Materials and Their Biocompatibility

    Author : Daniel O Carlsson; Maria Strømme; Leif Nyholm; Albert Mihranyan; Eva Malmström Jonsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nanocellulose; nanofibrillated cellulose; Cladophora cellulose; polypyrrole; TEMPO-mediated oxidation; composite; porosity; cytocompatibility; blood compatibility; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Abstract : Nanocellulose has received considerable interest during the last decade because it is renewable and biodegradable, and has excellent mechanical properties, nanoscale dimensions and wide functionalization possibilities. It is considered to be a unique and versatile platform on which new functional materials can be based. READ MORE

  3. 3. Coronal restoration in root-filled and non root-filled teeth : studies on periapical status, tooth survival, subsequent treatments and treatment decisions

    Author : Victoria Dawson; Malmö universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endodontics; Coronal restoration; Indirect restoration; Direct restoration; Root canal treatment; Decision process; Apical periodontitis; Qualitative Content Analysis;

    Abstract : The overall aim of this thesis was to study the following aspects ofdirect and indirect coronal restoration, primarily of root-filled teeth, withspecial reference to:• periapical health• the natural course of root-filled teeth, particularly furtherclinical intervention• the dentist´s decision-making process for root-filled teeth.The aims of coronal restoration are to restore the function and aestheticsof the tooth, with a tight marginal seal as protection from microbialleakage.

  4. 4. Electrified Integrated Kinetic Energy Storage

    Author : Magnus Hedlund; Hans Bernhoff; Markus Mueller; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flywheel energy storage; magnetic bearings; carbon composite; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : The electric car is a technically efficient driveline, although it is demanding in terms of the primary energy source. Most trips are below 50 km and the mean power required for maintaining speed is quite low, but the system has to be able to both provide long range and high maximum power for acceleration. READ MORE

  5. 5. Dielectric Properties of Liquid-Impregnated Porous Solids

    Author : Bo Nettelblad; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluid-solid interface; porous microstructure; temperature; ion-containing liquid; transport properties of porous media; brine; salinity; electric conduction; models of composite media; interface phenomena; dielectric relaxation; rock;

    Abstract : Dielectric spectroscopy is a versatile tool that can often be used as a non-destructive, indirect way of measuring other important properties (such as content of crude oil or degree of curing of a resin). The dielectric properties of materials are thus of interest in several circumstances and not only for materials used for electrical purposes (such as electrical insulation). READ MORE
