  1. 1. Engineering Nanofluids for Heat Transfer Applications

    Author : Nader Nikkam; Toprak Muhammet; Mamoun Muhammed; Yulong Ding; KTH; []
    Keywords : nanofluid; thermal conductivity; viscosity; heat transfer; heat transfer coefficient; HTC; SiC nanoparticles; Cu nanoparticles; mesoporous silica; CNT; microwave synthesis; Kemi; Chemistry;

    Abstract : Nanofluids (NFs) are nanotechnology-based colloidal dispersion prepared by dispersing nanoparticles (NPs) in conventional liquids, as the base liquid. These advanced fluids have displayed potential to enhance the performance of conventional heat transfer fluids. READ MORE

  2. 2. Investigation of electrical and magnetic properties of nanoparticles and nanofibers with the aim to tailor material properties of nanocomposites

    Author : Anna Jänis; Chalmers University of Technology; []
    Keywords : microscopy; ferrite; SiC; nanocomposite; nanowire; microwave absorbing properties; network analyzer; nanoparticle;

    Abstract : Nanocomposites are the subject of interest in this study which can be explained by the factum that using building blocks with dimensions in the nanosize range makes it possible to design and create new materials which can satisfy several functions at the same time for many applications. The applications of interest in this study belong to the microwave frequency region and for that reason a number of materials were investigated to define their microwave absorbing properties.

  3. 3. Silicon Carbide Reinforced Alumina and Mullite Ceramics

    Author : Stefan Gustafsson; Chalmers University of Technology; []
    Keywords : Ceramic Nanocomposites; Creep; SEM; SiC; Grain Boundaries; Microanalysis; Mullite; Pressureless Sintering; TEM; Alumina;

    Abstract : The aim of this work was to develop homogeneous ceramic nanocomposite materials with good thermal and structural stability as well as good mechanical properties. The development of microstructure was related to the material properties. READ MORE

  4. 4. Study of particle-current-electrocrystallization interactions in electroplating of Ni/SiC coatings

    Author : Santiago Pinate; Caterina Zanella; Peter Leisner; Jönköping University; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Composite coatings; Nanoparticles; Electrocrystallisation; Microstructure; Surface treatment; Pulse plating; Ultrasound agitation; Kompositbeläggningar; Nanopartiklar; Elektrokristallisering; Mikrostruktur; Ytbehandling; Pulsplätering; Ultraljudsomrörning;

    Abstract : Composite coatings have great potential due to the possibility to combine properties of two different materials in one coating. This way, new surface properties can be tailored and applied to any material's surface. READ MORE

  5. 5. Nanostructured materials for gas sensing applications

    Author : Kristina Buchholt; Per Eklund; Lars Hultman; Anita Lloyd Spetz; Harry L. Tuller; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : In this Thesis I have investigated the use of nanostructured films as sensing and contact layers for field effect gas sensors in order to achieve high sensitivity, selectivity, and long term stability of the devices in corrosive environments at elevated temperatures. Electrochemically synthesized Pd and Au nanoparticles deposited as sensing layers on capacitive field effect devices were found to give a significant response to NOx with small, or no responses to H2, NH3, and C3H6.
