Summary: This paper presents a comparative study on the swelling processes of free-standing graphene oxide membranes and GO laminates encapsulated with epoxy glue. The research reveals that the d-spacing of free-standing graphene oxide membranes can vary greatly depending on the ambient humidity and electrolyte type and concentration. On the other hand, the swelling of epoxy-encapsulated GO is limited. The physical constriction and intercalation of amines into GO laminates are believed to be the causes of this swelling suppression.

Summary: This study reports accurate quantum calculations of Helium atom sieving by two-dimensional graphtriyne layers with a new interaction potential. Despite expectations of limited quantum effects due to larger pore size compared to graphdiyne, strong quantum behavior was observed, attributed to selective adsorption resonances with a pronounced effect in the low temperature regime. This led to selectivity at very low temperatures and more efficient crossing of the membrane by heavier isotopes.

Summary: Encapsulation of active guest compounds inside metal-organic frameworks (MOFs) can lead to properties beyond those of bare MOFs and/or guest species. Core-shell composites show better accessibility to pores, optimal diffusion of substrate, and prevent aggregation and runoff of active guests, promoting synergistic effects. Advances in synthetic strategies and potential applications, such as environmental catalysis, gas separation, and sensing, are discussed in this review to promote new generations of MOFs based composites for energy-related applications.

Summary: In this article, a novel strategy for preparing bistable porous nanocrystals is presented, which involves anchoring switchable molecules in the pores of a host matrix through strong host-guest interactions. The loaded nanocrystals, based on a prototypical Fe(III) spin-crossover complex in MOF-808, exhibit a hysteretic thermal spin transition close to room temperature, regardless of the complex loading and the MOF particle size, while maintaining high porosity, making them promising for applications in chemical sensing.

Summary: The microporous bioderived Al dicarboxylate MIL-160(Al) MOF in its shaped form has shown potential as a candidate for biogas upgrading (BU) and/or carbon capture and storage (CCS). The adsorption isotherms of CO2, CH4, and N2 at different temperatures and pressures were studied, revealing the loading capacities and fitting with the dual-site Langmuir model. Uptake rate experiments and Response Surface Methodology (RSM) were used to calculate the driving force coefficients and maximize selectivity for CO2/CH4 and CO2/N2 mixtures. Breakthrough curve experiments were simulated using ASPEN Adsorption, confirming the potential of MIL-160(Al) for BU and/or CCS applications.

Summary: Metal-organic frameworks (MOFs) have gained interest in biomedical applications, with the mesoporous iron(III) carboxylate MIL-100(Fe) being one of the most studied MOF nanocarriers. Nanosized MIL-100(Fe) particles coordinate with drugs to achieve high drug loading and controlled release. A study investigated the interactions between the anticancer drug prednisolone and nanoMOFs, showing that prednisolone with phosphate groups had the strongest interactions and slowed down degradation, while prednisolone with sulfate groups had lower efficiencies and easily released in phosphate media. The nanoMOFs maintained their structure even after drug loading and degradation. Scanning electron microscopy and X-Ray energy-dispersive spectrometry were used to analyze the structural evolution.

Summary: Recent breakthrough experiments have identified iso-reticular Zr-MOFs, MIL-140B and MIL-140C, as promising sorbents for C6 isomer separation. The elution order of hexane isomers in MIL-140C exhibited an uncommon shift compared to MIL-140B, which was speculated to be caused by the flexibility of the MOFs. Through simulations, it was predicted that MIL-140B preferentially adsorbs n-C6 over 3MP, while MIL-140C slightly favors n-C6. The mobility of the isomers in MIL-140B and MIL-140C was found to be different, which explains the experimental inversion of elution order in MIL-140C.
