Calcium-mediated nitrogen reduction for electrochemical ammonia synthesis
The production of ammonia via the Haber–Bosch process is carbon-intensive and centralized, but electrochemical methods such as lithium-mediated processes in organic electrolytes could enable decentralized production using renewable energy. Calcium is now shown to mediate nitrogen reduction for ammonia synthesis.

Quantitative production of butenes from biomass-derived γ-valerolactone catalysed by hetero-atomic MFI zeolite
Production of olefins from biomass-derived γ-valerolactone could lead to sustainable chemical processes, but catalysts suffer from deactivation due to water. Here, a MFI-type zeolite doped with Nb(v) and Al(iii) shows >99% yield at 320 °C and catalyst stability over 180 hours.

Partial breaking of the Coulombic ordering of ionic liquids confined in carbon nanopores
The structure of ionic liquids under confinement is not well understood and hinders their widespread use for applications. Convincing evidence of partial breaking of Coulombic ordering of ions confined in subnanometre carbon pores is now provided.

Platinum–cobalt bimetallic nanoparticles in hollow carbon nanospheres for hydrogenolysis of 5-hydroxymethylfurfural
Although producing 2,5-dimethylfuran (DMF) from 5-hydroxymethylfurfural (HMF) is an attractive way to synthesize renewable fuels, achieving high yields for this reaction has proved difficult. PtCo bimetallic nanoparticle catalysts embedded in hollow carbon nanospheres now show improved catalytic performance for the hydrogenolysis of HMF to DMF (98% yield after 2 hours).

Managing the scarcity of chemical elements
The issues associated with the supply of rare-earth metals are a vivid reminder to all of us that natural resources are limited. Japan's Element Strategy Initiative is a good example of a long-term strategy towards the sustainable use of scarce elements.
