6. Emission of methane from northern lakes and ponds
Sammanfattning : Northern lakes and ponds are abundant and emit large amounts of the potent climate forcer methane to the atmosphere at rates prone to change with amplified Arctic warming. In spite of being important, fluxes from surface waters are not well understood. LÄS MER
7. Fermentative hydrogen and methane productions using membrane bioreactors
Sammanfattning : The role of energy as a stimulant for economic growth and environmental sustainabilityof any nation has made the focus on green fuels, including fermentative hydrogen (bioH2) andmethane (bioCH4), to be a priority for the World’s policy makers. Nigeria, as the most populousAfrican country, with worsening energy crisis, can benefit from the introduction of the bioH2 andbioCH4 technologies into the country’s energy mix, since such technologies have the potential ofgenerating energy from organic wastes such as fruit waste.

8. Bimetallic Palladium Catalysts for Methane Combustion in Gas Turbines
Sammanfattning : Catalytic combustion is a promising combustion technology for gas turbines, which results in ultra low emission levels of nitrogen oxides (NOx), carbon monoxide (CO) and unburned hydrocarbons (UHC). Due to the low temperature achieved in catalytic combustion almost no thermal NOx is formed. LÄS MER
9. Methane and Volatile Fatty Acids Production from Toxic Substrate
Sammanfattning : Challenges caused by climate change and global warming have created a demand for improvements in resource recovery and the promotion of a circular economy. Waste management is one such challenge for which more recycling options are required for producing materials and energy sources from wastes. LÄS MER
10. High (valent) on O2 : Ribonucleotide Reductase and Methane Monooxygenase
Sammanfattning : Macromolecular X-ray crystallography (MX) is a powerful method to investigate protein structures. However, proteins with redox-active centres and radicals are very susceptible to photoreduction. LÄS MER
