Summary: Nowadays, there are many reliable techniques available for the characterization of adsorption properties in the gas phase. However, for adsorption processes in solution, indirect characterization techniques are commonly used, which measure the remaining adsorbate concentration in the solution. In this study, a sensing method based on the magnetic properties of metal-organic frameworks (MOFs) containing paramagnetic metal centres is presented. This method allows for rapid, low-cost, and in situ direct measurement of the incorporated adsorbate within the porous material, enabling the determination of adsorbed mass and measurement of adsorption isotherm curves.

Summary: Metal-organic frameworks (MOFs) with controllable porous structures have been extensively studied, but achieving three-dimensional (3D) morphological control is still a challenge. This study investigates the conversion of zinc oxide nanowires into MOFs with the same morphology and applies the knowledge to generate complex 3D structures. It also shows the potential of this approach in accessing new MOF structures. The study highlights the importance of understanding the MO-to-MOF conversion for fabricating MOF materials with precisely tailored morphology.

Summary: This study investigates the recovery of different alcohols from water using the adsorptive separation properties of a flexible metal-organic framework (MOF) called MIL-88A(Fe). The results show that hydrophobicity of the alcohols plays a dominant role in their adsorption, with higher preference towards alcohols with more carbon atoms. Theoretical studies further demonstrate the importance of framework flexibility and diffusion in alcohol adsorption.
