Physical Chemistry

5 Molten oxide electrolysis is considered a promising route for extractive metallurgy with much reduced carbon dioxide emissions relative to traditional routes; now a new chromium-based alloy has been developed for use as an oxygen evolving anode that remains stable in the high-temperature corrosive conditions found during iron production via electrolysis.

4 Liquid gating tunes the carrier density in molybdenum disulfide, revealing unconventional superconductivity.

3 A general method of creating colloidal particles that can self-assemble into ‘colloidal molecules’ is described: surface patches with well-defined symmetries are functionalized using DNA with single-stranded sticky ends and imitate hybridized atomic orbitals to form highly directional bonds.

2 Electrons are shown to drive a structural transition in a pnictide superconductor.

1 Kelvin probe force microscopy can reveal the distribution of charge within a single naphthalocyanine molecule.
