16. Deep generated methane in the global methane budget
Abstract : Methane is a significant part of the global carbon cycle. The distribution of methane above and below the Earth’s surface suggests that atmospheric methane might be related to methane originating from the deep mantle. READ MORE

17. The role of deep hydrocarbons in the global hydrocarbon budget
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

18. Palladium Catalyzed Methane Oxidation for Emission Control
Abstract : The use of methane based fuels, such as natural gas and biogas, benefits from lower emissions of CO2, CO, NOx, non-methane HC, SOx and particulate matters compared to traditionally used liquid fossil fuels. However, the exhaust gases contain significant levels of unburnt CH4 residuals, which are desirable to minimize since CH4 is a strong greenhouse gas with high global warming potential. READ MORE

20. Methane dynamics in northern wetlands: Significance of vascular plants
Abstract : The studies presented in Papers I to VI illustrate several different aspects of the impact of vascular plants on methane emissions from northern natural wetlands. The subject has been approached on different scales, ranging from the study of microbial substrates in the vicinity of a single plant root, to an attempt to extrapolate some of the results to the entire northern hemisphere north of 50°N.
