  2. 1. Restraint in structures with young concrete : Tools and estimations for practical use

    Author : Majid Al-Gburi; Carsten Vogt; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : One of the widespread issues in concrete structures is cracks occurring at early age. Cracks that appear in the young concrete may cause early start of corrosion of rebars or early penetration of harmful liquids or gases into the concrete body. READ MORE

  4. 2. Epitaxy of group III-nitride materials using different nucleation schemes

    Author : Rosalia Delgado Carrascon; Vanya Darakchieva; Daniela Gogova; Alice Hospodková; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Group III-nitride materials, gallium nitride (GaN), aluminum nitride (AlN) and indium nitride (InN) have direct band gaps with band gap energies ranging from the infrared (InN) to the ultraviolet (GaN) and to the deep ultraviolet (AlN) wave-lengths, covering the entire spectral range from 0.7 eV to 6.2 eV upon alloying.

  5. 3. Development and Characterization of Reliable Graphene-based Materials for Lightweight and Efficient Thermal Management in Electronics

    Author : Markus Enmark; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat spreader; vapor chamber; thermal management; thermal interface material; wick structure; reliability testing; graphene;

    Abstract : The semiconductor industry continuously aims to increase the transistor density in integrated circuits to improve performance of electronics. As performance and transistor density increases, so does the power density of integrated circuits. READ MORE

  6. 4. 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

  7. 5. Thermal residual stresses, hardness and microstructural characterisation of functionally graded WC-Co composites

    Author : Cecilia Larsson; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Functionally graded materials (FGMs) incorporate gradual transitions in their microstructure and/or composition with distance. The gradients provide means to favourably engineer their thermomechanical properties by changing e.g., the local modulus, yield strength, state of residual stress etc. READ MORE
