Summary: Metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) are crucial components in crystalline porous materials, offering vast structural diversity and adjustability. By hybridizing MOFs or COFs with other materials, issues like poor conductivity and weak mechanical properties can be effectively addressed. Various hybridization techniques at different scales have been developed for the preparation of MOF and COF hybrids, with representative applications in electrochemical energy storage devices. The basic principles and mechanisms guiding hybridization have also been elucidated.

Summary: Zeolitic imidazolate framework-8 was synthesized in a containerless state using acoustic levitation, which affected the coordination connection of ligands and resulted in different particle size distribution compared to normal conditions. The influence of droplet evaporation during acoustic levitation synthesis was investigated using methanol as the solvent. Surface evaporation caused deformation, vibration, and shape oscillation of the droplets, leading to a decrease in particle size distribution.

Summary: Guest clusters in confined nanospaces have great influence on molecular recognition. Researchers have found that gas-cluster rearrangement can be systematically controlled to achieve tunable sorption and separation behavior in MOFs. By studying the packing geometries of CO2 and C2H2 clusters in CUK-1 material at different temperatures, they have successfully achieved high-purity separation of C2H2 using a one-step purification process.

Summary: The study demonstrates the reversible conformational switch of an arylopeptide between two distinct helical structures using side chain solvation, and investigates folding selectivity and solvent-side chain affinity in determining the global structure. A thermoresponsive arylopeptide with oligoether groups and an adjustment of solvent affinity by combining different side chain substituents were designed to achieve interconversion between helices.

Summary: In this study, MnCo2S4 nanosheet catalyst was successfully synthesized and found to exhibit superior performance in hydrogen evolution. Compared to MnCo2S4, MnCo2S4 showed low overpotentials, moderate Tafel slope, and excellent sustainability. The outstanding performance can be attributed to the increased number of electrochemically active sites and enhanced electronic conductivity on the catalyst surface.

Summary: Networks are important for describing relationships between people, roads between cities, reactions between chemicals, and other interactions. Bipartiteness, dividing the network into two groups, can facilitate the study of the network's structure. We have developed an algorithm that can find a near-optimal bipartisation within a reasonable time frame and used it to uncover the hidden structure of the CSD cocrystal network.
