  1. 1. Molecular beam study of non-adiabatic electron transfer in the Cl2+Ksurf surface reaction

    Author : Lars Hellberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; harpooning; electron transfer; Cl2; surface; exo-electrons; sticking; halogen; non-adiabatic; chemiluminescence;

    Abstract : Halogen molecules impinging on alkali metal surfaces constitute model systems for studies of charge transfer, dissociation dynamics and non-adiabatic energy dissipation in molecule-surface reactions. This thesis reports emission of exo-electrons and photons from the surface as a result of strong non-adabaticity in the Cl2 gas on K$^{solid}$ reaction. READ MORE

  2. 2. Some aspects on the reduction of olivine pellets in laboratory scale and in an experimental blast furnace

    Author : Jerker Sterneland; KTH; []
    Keywords : Olivine; pellets; pellet testing; reduction softening melting; MPBO; blast furnace; reduction; quenching; dissection; coating; sticking; coated pellets;

    Abstract : The reduction behaviour of the olivine iron ore pellet MPBOwas studied in laboratory scale at KTH as well as in the LKABexperimental blast furnace. Initially, a newreduction-under-load, or so-called reduction/softening/melting,test equipment was developed. READ MORE

  3. 3. Simulation of the Melting and Cooling of Palladium Clusters

    Author : Jan Westergren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; melting; energy transfer; density of states; metal clusters; cooling; collision; phase barrier; sticking;

    Abstract : The thermal behaviour of palladium clusters has been investigated using Monte Carlo simulation in various ensembles. Furthermore the energy transfer between palladium clusters and rare gas atoms has been calculated in simulated collisions aiming for a calculation of the cooling of clusters in a rare gas atmosphere.
