Chemistry

Definition

Chemistry is a branch of science that involves the study of the composition, structure and properties of matter. Often known as the central science, it is a creative discipline chiefly concerned with atomic and molecular structure and its change, for instance through chemical reactions.

    Nonribosomal peptide synthetases (NRPSs) produce vital natural products but have proven recalcitrant to biosynthetic engineering. Now, a combination of yeast surface display and fluorescence activated cell sorting (FACS) has been used to reprogram an L-Phe-incorporating module for β-Phe. The resulting module is highly selective and functions efficiently in NRPS pathways.

    Water oxidation is key to the production of chemical fuels from electricity. Now, guided by theory, NiCoFeP oxyhydroxide catalysts have been developed that require an overpotential lower than that required by IrO2. In situ soft X-ray absorption studies of neutral-pH NiCoFeP catalysts indicate formation of Ni4+, which is favourable for water oxidation.
