Copper represents an effective catalyst in reducing carbon dioxide to hydrocarbons or oxygenates, but it is often plagued by a low product selectivity and limited long-term stability. Choi et al report that copper nanowires with rich surface steps exhibit a remarkably high Faradaic efficiency for ethylene that can be maintained for over 200 hours.

Crystal structure and magnetism in rare-earth langasite: (a) the distorted Kagome lattice of the rare-earth ions in R3Ga5SiO14; about 1.5% of the rare-earth sites (orange) are occupied by the holmium ions; the unit cell is shown by thin solid lines; (b) experimental and theoretical magnetization curves of HoxLa3−xGa5SiO14 (x = 0.043) in external magnetic fields parallel to three crystallographic axes and at T = 5 K. Symbols - experiment, solid lines - model accounting for a ground Ho3+ quasidoublet and a Van-Vleck contribution of excited crystal-field states. The inset shows the local magnetic moments of Ho-ions in the saturation regime. Image credit: Weymann et al, doi: 10.1038/s41535-020-00263-9.

This Hubble image shows the massive galaxy cluster MACSJ 1206. Embedded within the cluster are the distorted images of distant background galaxies, seen as arcs and smeared features. These distortions are caused by the dark matter in the cluster, whose gravity bends and magnifies the light from faraway galaxies, an effect called gravitational lensing. This phenomenon allows astronomers to study remote galaxies that would otherwise be too faint to see. Overlaid on the image are small-scale concentrations of dark matter, represented in this artist’s impression in blue. Dark matter is the invisible glue that keeps stars bound together inside a galaxy and makes up the bulk of the matter in the Universe. These blue halos reflect how the galaxy cluster’s dark matter is distributed, revealed by new results from Hubble. Image credit: NASA / ESA / Hubble / G. Caminha, University of Groningen / M.
