16. Directed Evolution of Glutathione Transferases with Altered Substrate Selectivity Profiles : A Laboratory Evolution Study Shedding Light on the Multidimensional Nature of Epistasis
Abstract : Directed evolution is generally regarded as a useful approach in protein engineering. By subjecting members of a mutant library to the power of Darwinian evolution, desired protein properties are obtained. Numerous reports have appeared in the literature showing the success of tailoring proteins for various applications by this method. READ MORE

17. A mechanistic description of the evolution of aromatic tar during catalytic upgrading of the raw gas produced from biomass steam gasification
Abstract : The removal of tar from the raw gas produced during biomass gasification is a prerequisite for the viability of the process downstream of the gasifier. The tar, the composition of which is dominated by aromatics, readily condenses, leading to process disruption. READ MORE

18. Methane oxidation over palladium oxide. From electronic structure to catalytic conversion
Abstract : Understanding how catalysts work down to the atomic level can provide ways to improve chemical processes on which our contemporary economy is heavily reliant. The oxidation of methane is one such example, which is important from an environmental point of view. READ MORE

19. Hydrolytic and oxidative catalytic activities of bio-inspired dinuclear metal complexes
Abstract : A number of homo- and heterodinuclear complexes have been synthesized as structural and functional models for the the active sites of phosphoesterases and soluble methane monooxygenases. The complexes are based on four new dinucleating ligands containing a central, potentially bridging, phenolate moiety. READ MORE

20. A Catalytic and Mechanistic Investigation of Palladium-Phosphine Catalysed Aqueous Hydroxycarbonylation. Steric and Electronic Properties of the Ligands
Abstract : The steric and electronic properties of eight water-soluble phosphines (1-8) were investigated by different methods. Phosphines 1-6 were tested as ligands in palladium catalysed hydroxycarbonylation of styrene. READ MORE
