22. Substrate water binding to the oxygen-evolving complex in photosystem II
Abstract : Oxygenic photosynthesis in plants, algae and cyanobacteria converts sunlight into chemical energy. In this process electrons are transferred from water molecules to CO2 leading to the assembly of carbohydrates, the building blocks of life. READ MORE

23. 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

24. Water splitting in natural and artificial photosynthetic systems
Abstract : Photosynthesis is the unique biological process that converts carbon dioxide into organic compounds, for example sugars, using the energy of sunlight. Thereby solar energy is converted into chemical energy. Nearly all life depends on this reaction, either directly, or indirectly as the ultimate source of their food. READ MORE

25. Spectroscopic characterisation of surface hydroxyls during catalytic methane oxidation
Abstract : Implementation of methane rich fuels as to develop sustainable vehicle transports requires improved catalytic exhaust aftertreatment technologies to convert engine-out methane emissions to carbon dioxide and water by total oxidation. A main challenge is that water formed during combustion inhibits the methane oxidation reaction even over the most active palladium-based catalysts presently known. READ MORE
