Summary: This study analyzed the effects of temperature and physical parameters on adsorption capacity in the Lower Cambrian Niutitang Formation shale in northern Guizhou Province, China. A new adsorption model with two physical meaning parameters was constructed and validated. The study also calculated the isosteric enthalpy of adsorption in the shale and discussed the factors affecting it. The results showed that the isosteric enthalpy decreased with temperature increase and increased with an increase of TOC. A new method to predict adsorption isotherms at different temperature conditions was provided, yielding better prediction results. This study provided new insights into the thermodynamic characteristics of shale adsorption.

Summary: The study demonstrates that the melamine-functionalized MOF MIL101-Mela effectively removes organic dyes with nitro or sulfonate groups, outperforming other adsorbents. The results highlight the significance of hydrogen donors and acceptors in improving performance in dye removal.

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: Metal nanoparticles encapsulated in a MOF shell show remarkable catalytic properties, but commonly used capping agents decrease their reactivity. In this study, we developed a new method to prepare PVP-capped Au NPs@MOF-808 core-shell composites, and demonstrated for the first time that the capping PVP can be easily removed while maintaining the integrity of the MOF shell. The reactivity of the Au NPs@MOF-808 composites for selective oxidation reactions was significantly enhanced.

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.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
