  1. 6. Theory of Hydrogen Quantum Diffusion

    Författare :Thomas Mattsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; path-integrals; isotope effect; transition state theory; quantum; diffusion; hydrogen; first-principles calculations; nickel;

    Sammanfattning : Atomic hydrogen adsorbed on a metal surface is one of the simplest possible examples of chemisorption, yet it is very challenging. The adsorption and the very elementary process of surface diffusion, a single atomic jump, have been investigated theoretically using several methods. LÄS MER

  3. 7. Conceptual and empirical issues of technological change in the health care sector : Innovation and diffusion of hemodialysis and renal transplantation

  5. 9. On the determination of diffusion coefficients in bone

    Författare :Abdallah Shokry; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kalman filter; Mathematical model; Spatially dependent diffusion; Diffusion in bone; Diffusion coefficient; Conductivity; Elastic modulus; Porous materials;

    Sammanfattning : Diffusion in bone is needed for bone remodeling and bone healing. Understanding the phenomenon is often important for comprehension bone diseases. Mathematical modeling of the diffusion processes is a required prerequisite in the study of this important physical process in living bone tissue. LÄS MER
