18 Electrodeposition of hierarchically structured three-dimensional ​nickel–iron electrodes for efficient ​oxygen evolution at high current densities.

17 A purely theoretical method for predicting gas-phase chemical reaction rates shows strong agreement with experiment.

16 Spiral precipitation patterns in confined chemical gardens.

15 Multiple competing pathways direct a metallic solid to its molten state.

14 Synthesis and detection of a seaborgium carbonyl complex.

13 Cephalopod-inspired design of electro-mechano-chemically responsive elastomers for on-demand fluorescent patterning.

12 Germanene: a novel two-dimensional germanium allotrope akin to graphene and silicene.

11 Observation of an all-boron fullerene.

10 Discovery and introduction of a (3,18)-connected net as an ideal blueprint for the design of metal–organic frameworks.

9 Highly active copper-ceria and copper-ceria-titania catalysts for methanol synthesis from CO2.

8 Direct chemical conversion of graphene to boron- and nitrogen- and carbon-containing atomic layers.

7 An atomic force microscope tip bearing a single carbon monoxide molecule was used to resolve hydrogen-bonding contacts between molecules.

6 Metal-free molecular catalysts can be tethered to nylon to render them recoverable and recyclable.

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.
