      Negligible overpotential for HER: The front cover artwork was chosen to represent a 3D Ni–Mo electrocatalyst with negligible overpotential for the alkaline hydrogen evolution reaction (HER). The 3D nanoporous Ni–Mo electrocatalyst was fabricated and investigated for alkaline HER. On page 1138, Prof. P. B. Wan et al. show how they synthesized the electrocatalyst with well-controlled composition, desired dimensions, and nanoporosity to exhibit improved HER performance with low overpotential, high current density, ultrahigh activity, and durable stability, challenging that of Pt/C catalyst.

      The back cover artwork was chosen to highlight a novel supercapacitor material, based on a two-phase, self-assembling structure with a Cu-rich network with high electronic conductivity but limited faradaic activity locking a highly dispersed Mn-rich matrix that exhibits high faradaic activity. High-lateral resolution quasi-in situ soft X-ray fluorescence and absorption microspectroscopies allowed the elemental and chemical-state distribution to be obtained, enabling optimization of plating parameters.

      Crystal clear: The Rietveld analysis for the 94 Na3PS4⋅6 Na4SiS4 (mol %) glass-ceramic electrolyte, with a Na+ conductivity of 7.4×10−4 S cm−1, indicates that the phosphorus atoms in cubic Na3PS4 are partially replaced by silicon atoms. The electron-density distribution obtained by using the maximum-entropy method suggests that cubic Na3PS4 has three-dimensional Na+ conduction pathways.

      Negligible overpotential for HER: 3D nanoporous Ni–Mo electrocatalysts are fabricated using a facile and effective electrodeposition method. By optimizing the Ni/Mo ratio, electrodeposition current density and time, the overpotential for hydrogen evolution reactions (HER) can be lowered to 10 mV (vs. reversible hydrogen electrode). Both the activity and stability of the optimized HER catalyst are the best among the known non-precious-metal electrocatalysts.
