Summary: The fabrication of advanced membranes with simultaneously high electron and proton conductivities has been achieved through the thermal reduction and vertical confinement of graphene oxide (GO) channels. The improvement in electron conductivity is due to the removal of oxygen functional groups, while the extremely reduced channel size allows for selective proton transport and improved proton selectivity.

Summary: Subnanometer interlayer space in graphene oxide (GO) laminates is important for permselective membrane nanochannels. The precise control of nanochannel space and the role of confined nanochannel chemistry in selective water/ion separation are still challenging. This study used macrocyclic molecules with consistent basal plane but varying side groups to modify nanochannels in GO laminates, and demonstrated the side-group dependence of angstrom-precision tunability for channel free space and the energy barrier setting for ion transport. The study provides insights into functional-group-dependent intercalation modifications of GO laminates for structural control and nanochannel design.

Summary: In this study, laminated reduced graphene oxide (rGO) was used to induce the growth of SnCoS4 particles and self-assembled into a nanosheet-structured SnCoS4@rGO composite through a solvothermal procedure. The optimized material showed abundant active sites and facilitated Na. ion diffusion due to the synergistic interaction between bimetallic sulfides and rGO. As the anode material of sodium-ion batteries, this composite maintained a high capacity of 696.05 mAh g-1 after 100 cycles and a high-rate capability of 427.98 mAh g-1 even at a high current density of 10 A g-1. Our rational design provides valuable inspiration for high-performance sodium-ion battery anode materials.

Understanding the interactions between graphene sheets is crucial for their applications. In this study, we characterize the interlayer cohesion energies in graphene papers through mechanical separation and chemical reduction. The interlayer cohesion energy is correlated with the oxygen content, interlayer spacing, and electrical conductivity of the graphene papers, providing insight into the potential tunability of interlayer interactions.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
