Summary: The assembly of polyoxometalate clusters into layered structures, referred to as clusterphenes, has been reported. These 2D structures exhibit uniform hexagonal pores and in-plane electron delocalization properties. The resulting clusterphenes show improved stability and catalytic efficiency, thanks to the electron delocalization within the 2D layer.

Summary: By using flexible polymer chains to regulate collective interactions, researchers have successfully achieved the realization of crystal superlattices with precise organization of individual DNA-functionalized nanoparticles. Through programmable self-assembly and scale-accurate coarse-grained simulations, it was found that the system of bifunctionalized nanoparticles expands the parameter space for nanoscale crystalline structures. The effects of steric hindrance were accounted for with a geometric model, and solvent responses of polymer chains were utilized for reconfigurable self-assembly. These findings provide fundamental insights into programmable self-assembly and offer design rules for the construction of crystal superlattices.

Summary: By studying with X-ray, we found that ZnS NRs self-assemble into a bilayer 2D square superlattice at high surface pressure, and then transform into a 3D multilayer structure of the nanorods as the subphase temperature increases. Based on the extracted parameters, we propose a hierarchical packing model of anisotropic NRs self-assembly on the water surface.

Summary: This study developed a facile and universal method for the self-assembly of synthetic metal nanocrystals into 2D superlattices. By controlling the molecular weight of polymer ligands and van der Waals forces, the researchers achieved the construction of non-close-packing 2D monolayer gold nanocube superlattices with tunable interparticle distance and internal configurations. This strategy provides a robust route for fabricating nanocrystal superlattice structures and offers a promising platform for diverse functional materials.

Summary: Large-scale nanoalloys of Co-Pt ranging from 3 to 7 nm in size were modeled using realistic atomistic potentials and Monte Carlo simulations, showing a tendency to reproduce bulk-ordered phases and structures on the surfaces. Certain surface structures were found to be incompatible with the core structure, resulting in disorder underneath. Mixed compositions were predicted on some surfaces, indicating a frustration in chemical ordering in nanoalloys.

Summary: In this work, stable Sb3+ and Bi3+ codoped Cs2ZrCl6 microcrystals were prepared on a large scale for highly efficient white light emission using ionic liquids. The dual emissions originate from the associated self-trapped excitons of the [SbCl6](3-) and [BiCl6](3-) octahedra. The method allows for facile synthesis of large batches of microcrystalline powders and shows potential for future applications in the lighting field.

Summary: Powder X-ray diffraction is a key technique for characterizing the inorganic structure of colloidal nanocrystals, with a focus on observing the ordering of ligands. The observed ligand peak serves as a sensitive probe of ligand shell ordering, allowing for manipulation to achieve desired outcomes for the final colloidal system. Researchers have demonstrated that previously attributed excess ligands in the powder X-ray diffraction feature actually correspond to bound and ordered capping ligands.

Summary: Single site catalysts provide a unique platform for mimicking natural enzymes, but current research focuses more on preparing structural and functional models rather than considering the local chemical environment. A Co-centered porphyrinic polymer was reported, with a triazole linker forming hydrogen bonds with the CoN4 site to enhance the electrocatalytic reduction of CO2.

Summary: Supraparticles with high structural order and coloration from uniform, polyhedral metal-organic framework (MOF) particles were prepared through confined self-assembly processes. The study showed that the color of supraparticles changes with the size and internal structure of anisotropic building blocks, and angle-dependent coloration is attributed to the presence of ordered, onion-like layers at the outermost regions. Surprisingly, all supraparticle dispersions exhibit visible macroscopic coloration, indicating that local ordering is sufficient to generate interference effects.

Summary: This article introduces a method for structurally characterizing powder samples by modeling the contribution of particle shape to total scattering data. The method models the shape contribution to small-angle scattering using a shape function, which is obtained by averaging common volume functions for a discrete set of directions. Particle size and size dispersity are accounted for through scaling and convolution with a probability distribution. The algorithm presented here is computationally efficient and can be directly incorporated into existing routines for powder total scattering analysis.

Summary: This review systematically summarizes recent advances in MOFs based catalysts for CO2 hydrogenation towards diverse products. It covers the synthesis strategies for different kinds of MOFs based catalysts, selective hydrogenation of CO2 towards CO and methane over various metal nanoparticles/MOFs composites, heterogenization and isolation of molecular catalysts by MOFs for producing formic acid, selective hydrogenation of CO2 towards methanol based on interface structures of Cu, Zn, and metal nodes of MOFs, the synergy between auxiliary sites and noble metal, and tandem catalytic systems of molecular catalysts and Lewis acid sites. The integration of multiple metal sites, promoters, and cocatalysts into MOFs for the selective hydrogenation of CO2 to C2+ products is also discussed. The stability of MOFs based catalysts for CO2 hydrogenation reaction is addressed, and the future perspectives for MOFs based catalysts for selective CO2 hydrogenation and mechanism research are proposed.

Summary: Bifurcations in kinetic pathways play a crucial role in determining the evolution of a system. The authors use confined self-assembly to observe the formation of decahedral clusters in colloidal particles, which are found to be thermodynamically stable. They reveal a bifurcation in the early nucleus shape during the crystallization process and provide a geometric argument for the kinetic hindrance of decahedral clusters and the dominant formation of icosahedral clusters.
