  2. 1. Substrate water binding to the oxygen-evolving complex in photosystem II

    Author : Håkan Nilsson; Johannes Messinger; Wolfgang Schröder; Robert L. Burnap; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photosynthesis; Photosystem II; water oxidation; oxygen evolution; substrate water exchange; membrane-inlet mass spectrometry;

    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

  4. 2. Mononuclear Ruthenium Complexes that Catalyze Water to Dioxgen Oxidation

    Author : Lianpeng Tong; Licheng Sun; Randolph Thummel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ruthenium complex; Homogeneous catalysis; Water oxidation; O2 evolution; anionic ligand; Molecular catalyst; Electrocatalysis; Kinetics; Artificial photosynthesis; Light-driven; Immobilization of catalyst;

    Abstract : The theme of this thesis is the development of mononuclear Ru-based complexes that are capable of catalyzing the water oxidation (or O2-evolving) reaction, e.g. 2 H2O → O2 + 4 H+ + 4 e−. Several families of mononuclear Ru water oxidation catalysts were designed and prepared. READ MORE

  5. 3. Emerging Paradigms in the Convergence of Cloud and High-Performance Computing

    Author : Daniel Araújo De Medeiros; Ivy Bo Peng; Stefano Markidis; Pawel Herman; Valeria Cardellini; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High-performance computing; Kubernetes; airflow; elastic scaling; MPI; S3; Datalogi; Computer Science;

    Abstract : Traditional HPC scientific workloads are tightly coupled, while emerging scientific workflows exhibit even more complex patterns, consisting of multiple characteristically different stages that may be IO-intensive, compute-intensive, or memory-intensive. New high-performance computer systems are evolving to adapt to these new requirements and are motivated by the need for performance and efficiency in resource usage. READ MORE

  6. 4. Island-based Polygeneration Systems : On the Feasibility of Solar-Biomass-driven Distributed Concepts

    Author : Moritz Wegener; Anders Malmquist; Andrew R. Martin; Antonio Isalgué; Natasa Nord; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polygeneration; Distributed energy systems; Biomass; Solar energy; PV-Battery; Small-scale energy systems; techno-economic analysis; Island-based systems; Energy Technology; Energiteknik;

    Abstract : The colossal risks and challenges posed by climate change require innovative solutions that must fulfil energy service demands sustainably. The concept of small-scale, biomass-based polygeneration (SBP) is one such technological approach, which optimizes locally supplied fuels to provide several energy services like electricity, heating, cooling, potable water, and/or bio-chemical products.
