  2. 6. Experimental investigation of hydrocarbon formation and transformation under Earth´s upper mantle conditions

    Author : Anton Kolesnikov; Vladimir Kutcherov; Bertil Sundqvist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; theory of deep abiotic petroleum origin; natural gas; hydrocarbons; methane; ethane; graphite; hydrogen; high pressure; high temperature; CONAC; BARS; diamond anvil cell; Raman; X-ray; gas chromatography; Engineering mechanics; Teknisk mekanik;

    Abstract : The theory of the abyssal abiotic petroleum origin considers oil and natural gas to begenerated in the Earth’s upper mantle. Hydrocarbons migrate further through the deep faults into the Earth’s crust, where they can form oil and gas deposits in any kind of rock in any kind of structural position. READ MORE

    Abstract : Nowadays, the issue of global warming and related environmental problems got widespread awareness among scientific society, politics, the industry as well as it has affected our everyday life. The reason for such a negative impact on the atmosphere is attributed mainly to human activities. READ MORE

  6. 9. High pressure and high temperature behavior of TiAlN

    Author : Niklas Norrby; Magnus Odén; Mats Johansson Johansson; Helen Blomqvist; Linköpings universitet; []
    Keywords : ;

    Abstract : This licentiate thesis mainly reports about the behavior of arc evaporated TiAlN at high pressures and high temperatures. The extreme conditions have been obtained in metal cutting, multi anvil presses or diamond anvil cells. Several characterization techniques have been used, including x-ray diffraction and transmission electron microscopy. READ MORE

  7. 10. Mössbauer spectroscopy under high pressures and temperatures

    Author : Elke Hålenius; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Mössbauer; high pressure - high temperature; iron; olivine; Geovetenskap; Earth sciences; Geovetenskap; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

    Abstract : Iron plays a very important role in Earth materials. 57Fe- Mössbauer spectroscopy provides valuable information on the oxidation state and the near surrounding of iron atoms in crystal structures. READ MORE
