Summary: Step-shaped adsorption-desorption of gaseous payloads by flexible metal-organic frameworks can facilitate the delivery of large usable capacities with reduced energetic penalties. The multivariate linker approach is a powerful tool for tuning the phase change behavior of flexible frameworks. In this work, a multivariate framework was developed with a considerably reduced threshold pressure and desirable adsorption-desorption profile for efficient storage and delivery of weakly physisorbing species.

Summary: The solvothermal assembly of copper(II) cations and 5-(pyridine-3-yl)isophthalate linkers with different positions of substituted methyl groups produced four ligand-induced metal-organic framework (MOF) isomers. These isomers showed diverse selective gas adsorption properties and framework flexibilities heavily dependent on the methyl position, with the capability of effectively separating binary gas mixtures. Altering the methyl position led to tailored uptake capacities, adsorption selectivities, and framework hydro-stability. This study highlights the significance of the positional effect of functional groups in modulating MOF structures and properties.

Summary: By anchoring CuI ions with synergistic dual-pyrazol sites of MOF-303, high C2H2 packing density and efficient C2H2/CO2 separation were achieved. Adsorption experiments demonstrated that CuI@MOF-303 could quickly adsorb C2H2 with a high density, surpassing any previously reported adsorbents. CuI@MOF-303 also exhibited a high C2H2/CO2 selectivity and separation factor, making it a promising candidate for industrial C2H2 purification.

Summary: Flexible metal-organic frameworks (MOFs) exhibit stepwise adsorption and have the potential to revolutionize conventional separation systems. However, MOFs in powder form need to be shaped for industrial applications. This study aimed to validate the mechanism behind the slacking of gate adsorption from both theoretical and experimental perspectives. Molecular dynamics simulations confirmed the sequential deformation of flexible motifs within MOF particles as a key factor contributing to the slacking phenomenon. Experimental validation showed the relationship between the volume expansion ratio of MOFs and the degree of slacking. These findings enhance the understanding of the slacking mechanism and guide the fabrication of molded MOFs with high adsorption efficiency.

Summary: We present an autonomous chemical logic gate based on a switchable metal-organic framework (MOF) composite that functions as an AND gate. By using hydrogen and oxygen gas streams as binary inputs, the catalytic formation of water induces a structural transition of the MOF, resulting in a detectable drop in conductivity of the composite only when both gases come in contact with it.

Summary: Pore size is crucial in determining the performance of metal-organic frameworks (MOFs) in various applications. However, the relationship between pore size and properties is difficult to study due to the lack of ideal structure models. In this work, a method was developed to modulate the ratio between large and narrow pore phases in a flexible MOF, MIL-88B. Gas sensitivity and selectivity dependent on pore size were studied, and the optimized MIL-88B-20% sample showed excellent sensing performance. This study not only provides a method to synthesize ideal structure models for studying the relationship between pore size and properties, but also inspires the development of high-performance gas sensing materials.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
