5. 3. Directed Evolution of Glutathione Transferases with Altered Substrate Selectivity Profiles : A Laboratory Evolution Study Shedding Light on the Multidimensional Nature of Epistasis

   Author : Wei Zhang; Bengt Mannervik; Bengt-Harald Jonsson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; glutathione transferase; azathioprine; directed evolution; semi-rational design; catalytic mechanism; saturation mutagenesis; reduced amino acid alphabets; molecular docking; protein evolution; multivariate data analysis; epistasis; fitness landscape; evolutionary trajectories; Biochemistry; Biokemi; Biokemi; Biochemistry;

   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

6. 4. Functional Materials for Perovskite Solar Cells

   Author : Wei Zhang; Lars Kloo; Neil Robertson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; perovskite solar cell; photovoltaic device; lead-free light absorbers; hole-transport materials; coordination complexes; p-type dopants; organic salts; surface passivation.; Kemi; Chemistry;

   Abstract : Energy plays a significant role in our daily lives, but most energy provided by fossil fuels causes serious environmental problems including air pollution, global warming, and ecological damage. In addition, it has been estimated that all of our fossil fuels will run out in 2088 and thus it is highly important to study and apply renewable energy sources. READ MORE
