Summary: We developed a simple method for synthesizing N-doped carbon nanospheres with uniform and tunable sizes. The synthesis involves the incorporation of EDTA into the emulsion droplets of phenolic resin oligomers, providing surface charges to prevent the coalescing of the droplets. The resulting N-doped carbon nanospheres have highly uniform sizes and shapes, and can be crystallized into opaline structures for fabricating opaline lattices with brilliant colors. The EDTA also promotes the formation of graphitic-N, making the nanospheres highly active electrocatalysts.

Summary: In this study, monodispersed polystyrene spheres with an average size of 50 nm were successfully prepared using the emulsion polymerization method. The size and size distribution of the spheres were controlled by optimizing synthesis parameters such as the concentration of monomer, initiator, and surfactant, as well as the type of surfactant and the time and temperature of polymerization. The results indicate that the molar ratio and concentration of monomer and surfactant, along with the polymerization temperature, are the main factors affecting the size of the polystyrene beads.

Summary: By tiling small-area nanopatterns in a slightly overlapped fashion, a practical solution to the preparation of large-area flexible molds in roll-to-roll nanoimprint lithography (R2R NIL) is presented. This is achieved by sequentially performing the UV NIL processes onto self-replicable UV-curable resin drops using a small tile mold. The control of tile NIL force and several parameters is crucial to minimize the seams between tiles.

Summary: In this study, single metal Pb, In and bimetallic PbIn catalysts were prepared and used for aqueous CO2 electroreduction. The bimetallic PbIn catalysts showed better catalytic performance than single metal catalysts, with the Pb7In3 catalyst exhibiting the highest formic acid faradaic efficiency. The excellent performance of Pb7In3 catalyst may come from its larger electrochemical active surface area, lower charge-transfer resistance, and the synergistic effect of Pb and In in the catalyst.

Summary: Researchers have successfully regulated the performance of single atom tailored nano-catalysts through a single atom-cavity coupling strategy. They deposited Ru single atoms on the surface concavities of PtNi nanoparticles, resulting in the formation of Ru-ca-PtNi catalysts. The Ru-ca-PtNi catalyst exhibited high activity and excellent durability in methanol oxidation reaction. Furthermore, the coupling of Ru single atoms with cavities accelerated the CO removal and the high diffusion barrier of Ru single atoms in concavities contributed to the catalyst's stability.

Summary: Employing lithium-rich layered oxide (LLO) as the cathode in all-solid-state batteries (ASSBs) is desired for high energy density, but its poor kinetics due to low electronic conductivity and oxygen-redox-induced structural degradation hinders its application. This study enhances the charge transfer kinetics of LLO by constructing efficient electron transport networks within solid-state electrodes, reducing electron transfer resistance, and stabilizes the lattice oxygen of LLO through an infusion-plus-coating strategy, suppressing interfacial oxidation and structural degradation. The LLO-based ASSBs exhibit high discharge capacity and long cycle stability, providing important insights for the development of high-energy-density ASSBs.
