  2. 1. Density functional study of mono-vancacies in metals and austenitic steel alloys

    Author : Delczeg Lorand; Vitos Levente; Korzhavyi Pavel; Ann E. Mattsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; atomic defects; metalls; alloys; vacany; vacancy formation energy;

    Abstract : Trough the following pages a comprehensive study of open structures will be shown, including mono-vacancy calculations and open surfaces. These are electronic structure calculations using density functional theory within the exact muffin tin method. READ MORE

  4. 2. Design and Construction of Low-Temperature Scanning Tunnelling Microscope for Spectroscopy

    Author : Joakim Lindahl; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mechanical properties; thermophysical properties; stepper motor; ultra-high vacuum; inertial-mass; low temperatures; scanning tunneling microscopy; optical propertie; Fysik; Semiconductory physics; Physics; scanning tunneling luminescence; local probe; photon emission; local carrier injection; Halvledarfysik; Fysicumarkivet A:1998:Lindahl;

    Abstract : This thesis discusses some of the fundamental requirements needed to be fulfilled when constructing a low temperature scanning tunnelling microscope (STM). Three different designs, two non-vacuum and one ultra-high vacuum (UHV), based on either inertial-mass or novel stepper motor principles are presented. READ MORE

  5. 3. Methodology for evaluation of hazards from solid waste and landfill-generated leachate

    Author : Britt-Marie Svensson; Lennart Mathiasson; Lennart Mårtensson; Ann-Sofi Rehnstam-Holm; Kenneth M. Persson; Högskolan Kristianstad; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Analytical protocol; organic pollutants; toxicity test; landfill leachate; leachate treatment; leaching test; waste acceptance criteria; Chemistry; Kemi; NATURAL SCIENCES; NATURVETENSKAP; leaching test; waste acceptance criteria.;

    Abstract : A methodology based on an analytical protocol for evaluation of hazards from landfill leachate and solid waste is described. A dynamic analytical protocol, the LAQUA protocol, including measurements of inorganic and water-quality parameters, polar and non-polar organic marker compounds, and toxicity, was constructed.

    Abstract : Avfall har alltid uppkommit i alla samhällen i alla tider. Det vanligaste sättet att hand om det har varit att samla avfallet i soptippar (deponier) på mark som ansetts obrukbar, t.ex. i sankmarker utanför bebyggelsen. READ MORE
