  5. 3. Atom and Group Transfer Reactions Involving High-valent Iron Complexes

    Author : Yong Li; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Iron enzymes; high-valent iron intermediates; bio-inspired iron complexes; FeIV=O; FeIV=NR; catalytic reactions; electronic effects; steric restriction.;

    Abstract : Iron enzymes play critical roles in biological oxidation reactions by utilizing highly reactive high-valent iron intermediates, such as FeIV=O, FeV(O)(OH), and FeIV=NR species, for catalytic reactions. These intermediates exhibit remarkable catalytic behavior with high reactivities and high regio- and stereospecificity in various biochemical reactions. READ MORE

  6. 4. Computational Studies on Homogeneous Water Oxidation Catalysts

    Author : Ge Li; Mårten S. G. Ahlquist; Moyses Araujo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational studies; homogeneous; water oxidation catalysts; ruthenium; iron; mechanisms; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : To combat the increasing energy demand and climate change, artificial photosynthesis is a promising approach to producing renewables by storing energy into chemicals and fuels. Water oxidation, responsible for offering electrons and protons to the reduction reactions, suffers from slow kinetics. READ MORE

  7. 5. Bio-based nonionic antimicrobial polymers with isatin or indole functionality

    Author : Xiaoya Li; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antimicrobial polymers; nonionic; isatin; indole; miscibility; hemolytic activity; cytotoxicity;

    Abstract : Infections by pathogenic microorganisms remain one of the most serious concerns in several areas, particularly in hygienic applications. Antimicrobials have been used to combat these infections. Using small molecular antimicrobials as additives or coatings is an industrially adopted strategy. READ MORE
