  1. 1. Thermal physics of asteroids

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johan S. V. Lagerros; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; asteroids; infrared emission; thermophysical models; Astronomi; NATURAL SCIENCES Physics Astronomy and astrophysics; NATURVETENSKAP Fysik Astronomi och astrofysik; astronomi; Astronomy;

    Abstract : The thermal infrared and microwave emission from asteroids have many applications. Fundamental physical properties can be investigated, which have implications for the geophysical evolution of the asteroids, and the early history of the solar system.A new thermophysical model of asteroids is presented.

  2. 2. Finite temperature properties of elements and alloy phases from first principles

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hossein Ehteshami; Pavel A. Korzhavyi; Andrei V. Ruban; Tilmann Hickel; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materials Science and Engineering; Teknisk materialvetenskap; Physics; Fysik;

    Abstract : First principles calculations are usually concerned with properties calculated at temperature 0 K. However, the industrially important materials are functioning at finite temperatures. READ MORE

  3. 3. Model-based Analysis and Design of Atomic Layer Deposition Processes

    University dissertation from Lund University (Media-Tryck)

    Author : Anders Holmqvist; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atomic layer deposition; Heterogeneous reaction kinetics; Limit-cycle dynamics; Parameter estimation; Multi-objective optimization; Dynamic optimization; Scale-up analysis;

    Abstract : Atomic layer deposition (ALD) is a thin-film manufacturing process in which the growth surface is exposed to non-overlapping alternating injections of gas-phase chemical precursor species separated by intermediate purge periods to prevent gas-phase reactions. ALD is characterized by sequential self-terminating heterogeneous reactions between highly reactive gas-phase precursor species and surface-bound species which, when allowed sufficient conditions to reach saturation, results in highly conformal films, on both planar and topographically complex structures.

  4. 4. Extension of PC-SAFT to model inhomogeneous and transport properties

    University dissertation from Lund University (Media-Tryck)

    Author : Gulou Shen; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : CO2 separation plays an important role in greenhouse gas emission mitigation, in bio-fuel production via biomass gasification as well as in biogas upgrading. The current CO2 separation technologies are energy intensive, and new cost-effective CO2 separation technologies are needed. READ MORE
