  1. 1. Carbon-graphite fiber-reinforced polymers for implant suprastructures

    Författare :Susanna Segerström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Implant prostheses; Matrix; MMA; PMMA nanoparticles; Copolymer; Surface treatment; Size; Adhesion; SEM; Mechanical properties; Physicochemical properties.;

    Sammanfattning : Carbon-graphite fiber-reinforced polymers (CGFR) can be used as the core material for implant-retained prostheses as an alternative to metal frameworks. The purpose was to formulate and develop carbon-graphite fiber-reinforced polymers intended for implant suprastructures and to determine physicochemical, mechanical properties and possible cytotoxic effects.

  3. 2. Nanoplasmonic Alloy Hydrogen Sensors

    Författare :Ferry Nugroho; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; indirect nanoplasmonic sensing; plasmonic sensors; hydrogen sensors; polymers; fiber optics; nanofabrication; localized surface plasmon resonance; alloy nanoparticles; carbon capture and storage; sensors; palladium;

    Sammanfattning : The hydrogen economy proposes hydrogen gas as the main energy carrier thanks to its high energy density and the possibility to produce it in a sustainable way without CO2 emission. However, the wide flammability range of hydrogen-air mixtures dictates that hydrogen sensors will be a mandatory accessory to any appliance or vehicle fueled by hydrogen. LÄS MER

  4. 3. Hydrothermal recycling of natural and synthetic polymers to functional carbon materials

    Författare :Karin Adolfsson; Minna Hakkarainen; Istvan Furo; Andrea Kruse; KTH; []
    Nyckelord :;

    Sammanfattning : Utilizing renewable recourses and waste recycling are necessary for reaching a circular resource society. The concept of this thesis was to set up a sustainable recycling route, suitable even for low quality biopolymer and plastic waste for production of functional carbon materials. LÄS MER

  5. 4. A Framework for Fatigue Analysis of Carbon Fiber Reinforced Polymer Structures

    Författare :Sara Eliasson; Zuheir Barsoum; Per Wennhage; Kim Branner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heavy-duty vehicles; Fatigue; Carbon fiber reinforced polymer; Multi-scale modeling; Probabilistic modeling; Tunga fordon; Utmattning; Kolfiberkomposit; Probabilistisk modellering; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Our society depends on functional road communication, and Heavy Duty Vehicles (HDVs) offer convenient and limitless possibilities of transport and services. However, HDVs account for a quarter of the European Union's CO2 road emissions. There is a substantial need to reduce the CO2 emissions of HDVs to ensure a low negative environmental impact. LÄS MER

  7. 5. Biochemical modification of wood components

    Författare :Peter Josefsson; Lars Wågberg; Mark Rutland; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : The degradation of cellulose found in wood is one of the most important degradation processes for the carbon flux on earth. The degradation is performed by microorganisms that typically use enzymes. LÄS MER
