  1. 6. Modeling colloidal nanoparticles: From growth to deposition

    Författare :Joakim Löfgren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gold; DLVO; thermodynamics; van der Waals; density functional theory; modeling; deposition; dispersive interactions; anisotropic; colloidal nanoparticles; nanorods;

    Sammanfattning : In recent decades metal nanoparticles (NPs) have been the subject of intense research. The interest stems from the NPs physicochemical properties that can be conveniently tuned through, e.g., their size, shape or composition. LÄS MER

  3. 7. Sintering of cemented carbides : experiments and modeling

    Författare :Sven Haglund; KTH; []
    Nyckelord :;

    Sammanfattning : During sintering of cemented carbides large volumetricshrinkage takes place. About half the volume of the originalgreen body is lost during this process. Due to lotal densitydifferentes within the green body undesired shape changes mayalso occur during sintering. LÄS MER

  4. 8. Fatigue crack growth in fiber metal laminates : experiment and modeling

    Författare :Per Hofslagare; Michel van Tooren; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Fiber Metal Laminates (FML) is a class of materials with highly resistant fatigue behavior, developed primary for the aerospace industry. The laminates are comprised of alternating layers of high strength aluminwn sheet and fiber reinforced polymers. LÄS MER

  5. 9. On mechanical characterization and multi-scale modeling of Lithium-ion batteries

    Författare :Priyank Gupta; Peter Gudmundson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion batteries; constitutive modeling; U-shape bending tests; electrochemistry; multi-scale modeling; three-dimensional laminate theory.; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : Over the last few decades, rechargeable lithium-ion batteries have been extensively used in portable instruments due to their high energy density and low self-discharge rate. Recently, lithium-ion batteries have emerged as the most promising candidate for electric vehicles and stationary energy storage. LÄS MER
