  2. 1. Carbon Nanotube Based Interconnect Material for Electronic Applications

    Author : Di Jiang; Chalmers University of Technology; []
    Keywords : electrical interconnect; bump; densification; electronics packaging; carbon nanotube; three dimensional integration; flexible electronics; through silicon via; transfer;

    Abstract : Carbon nanotubes (CNTs) are considered as a candidate material for future electronicinterconnect applications. This thesis summarizes the research work on thefabrication and characterization of CNT-based interconnect systems, and exploresthe possibilities of integrating CNTs into various electronic interconnect scenarios.

  4. 2. Surface Densification of Solid Wood : Paving the Way Towards Industrial Implementation

    Author : Benedikt Neyses; Dick Sandberg; Alexander Pfriem; Luleå tekniska universitet; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; Träteknik; Wood Science and Engineering;

    Abstract : Surface densification of a piece of solid wood results in an increase in density and in hardness in the whole or a part of the densified material, and is one of the ways of improving the properties and value of low-density wood species. Despite efforts for many years, mass commercialisation of either bulk- or surface-densified wood products has not yet been achieved. READ MORE

  5. 3. Cemented Carbide Sintering : Constitutive Relations and Microstructural Evolution

    Author : Anders Petersson; KTH; []
    Keywords : Cemented carbides; Sintering; Constitutive relations; Microstructure; Densification; Modelling;

    Abstract : Cemented carbides based on tungsten carbide and cobalt arecommonly produced by a powder metallurgy route including liquidphase sintering. The pressed compact densifies to almost halfits volume during sintering due to pore elimination. READ MORE

  6. 4. Vertical Extension of Buildings

    Author : Rikard Nilsson; Avdelningen för Byggproduktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability; Densification; energy-efficient renovation; Urban Development; Stakeholder;

    Abstract : Many policy targets have been developed with the aim of reaching a more sustainable development; more specifically, thestudied policies target energy use and urban growth. For example, by 2050 the aim is that the European Union will havereduced its greenhouse emissions by 90%. READ MORE

  7. 5. Rapid sintering of ceramics by intense thermal radiation

    Author : Duan Li; Zhijian Shen; Lutz-Michael Berger; Stockholms universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Sintering; sintering by intense thermal radiation; spark plasma sintering; heat transfer; mass transfer; scattering; coalescence; densification; grain growth; numerical simulation; porous ceramic; foaming; nanostructure; hierarchical heterogeneities; permeability; Materials Chemistry; materialkemi;

    Abstract : Sintering is an important processing step for obtaining the necessary mechanical stability and rigidity of ceramic bulk materials. Both mass and heat transfer are essential in the sintering process. The importance of radiation heat transfer is significantly enhanced at high temperatures according to the well-known Stefan-Boltzmann’s law. READ MORE
