Summary: Medi-MOF-1 is a porous Metal-Organic framework (MOF) made of Zn(II) and curcumin. The crystal obtained was characterized using powder X-ray diffraction (PXRD) and scanning electron microscopy (SEM). A micrometer-sized crystal with similar morphology was successfully obtained using the solvothermal method. Thanks to its high surface area, stability, and abundant pores, the as-synthesized Medi-MOF-1 can be used to adsorb various gases (H-2, CO2, CH4, and N-2) and iodine (I-2). The activated sample showed a high I-2 adsorption ability of 1.936 g g(-1) at room temperature through vapor diffusion. Additionally, the adsorbed I-2 could be released slowly in ethanol, indicating its potential application for iodine adsorption.

Summary: This article presents a new approach to water-processable metal-organic framework materials. By using amphiphilic organic building blocks consisting of polar carboxylate groups and non-polar alkyl chains, these materials can assemble into porous framework structures via bonding to kinetically labile sodium ions from concentrated aqueous solution. The obtained materials, termed amphiphile salt frameworks, are thermally and mechanically stable and have persistent microporous channels accessible to several gases. They can be reversibly assembled/disassembled by crystallization from or dissolution in water.

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.
