    Abstract : The principles of natures own light-driven water splitting catalyst, Photosystem II (PSII), can in the future inspire us to use water as electron and proton source to generate light-driven H2 production. To mimic this challenging step, it is important to understand how the enzyme system can oxidize water. READ MORE

    Abstract : Soils offer humanity a multitude of ecosystem services, including production of food and clean drinking water, and many such services are driven by soil microbial communities. However, human activities are constantly affecting soil ecosystems through altered land use or various management strategies, and thereby influence microbial communities and their functions.
