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.

    Controlling crystallite size can lead to improved applications. Here, this is achieved by a combination of metal ions, organic linkers, and polymers; the resultant membrane displays promising CO2/N2 separation properties and hydrolytic stability.

    Typical methods for the enantioselective α-functionalizations of ketones join ketone enolate nucleophiles with carbon or heteroatom electrophiles. We report an umpolung strategy to achieve this transformation with masked ketone electrophiles and a wide range of conventional heteroatom and carbon nucleophiles catalysed by a metallacyclic iridium catalyst in high yield and enantioselectivity.

    Yarovinsky and colleagues identify the alarmin S100A11, which is released from Toxoplasma gondii–infected cells, as the trigger for immune responses in humans. S100A11 induces expression of the chemokine CCL2, which recruits inflammatory CCR2+ monocytes to the sites of infection.
