Abstract Co and N co-modified mesoporous carbon composites (Co/N-mC) have been simply prepared at low cost from the carbonization of ZIF-67 wherein not only providing surface N-modification for promoting adsorption behavior acidic dyes, but also constructing a magnetic property convenient separation. Co/N-mC composite presented ability MO (178 mg g −1 ) > RhB (141 (T = 25 °C, pH 7.0, C 0 20 ...

The landscape of possible polymorphs for some metal–organic frameworks (MOFs) can pose a challenge controlling the outcome their syntheses. Demonstrated here is use template to control in vapor-assisted formation zeolitic imidazolate framework (ZIF) powders and thin films. Introducing small amount either ethanol or dimethylformamide vapor during reaction between ZnO 4,5-dichloroimidazole result...

Abstract Recently, metal–organic frameworks (MOFs) have received considerable attention as highly efficient adsorbents for dye wastewater remediation. However, the immobilization of MOFs on substrate surfaces to fabricate easy recyclable via a facile route is still challenge. In this work, ZIF-67/cotton fibers removal were prepared in large-scale using simple coordination replication method. Th...

−Metal organic frameworks (MOFs) are porous crystalline materials of one-, two-, or three-dimensional networks constructed from metal ions/clusters and multidentate organic linkers via coordination bonding, which are emerging as an important group of materials for energy storage, CO2 adsorption, alkane/alkene separation, and catalysis. To introduce newcomers in chemical engineering discipline t...

Controlling the metal-organic framework (MOF)-matrix interface is a useful strategy to improve gas separation performance of mixed matrix membranes (MMMs). Although polymer blending has been investigated enhance MMM performances, its true strength, i.e., aligning and additive chemistries interfacial compatibility ultimately performance, only poorly investigated. In this work we demonstrate how ...

Zeolitic imidazolate frameworks (ZIFs) undergo pressure-induced phase transitions that are peculiar to each ZIF. The transition is associated with the rotation of imidazolate, and it accompanied by an increase their pore openings, affecting ZIFs performance in separation processes. This phenomenon known as gate opening or swing effect. Here we report metal dependence ambient pressure high (HP) ...

The high-resolution three-dimensional structure of a synthetic 57-residue peptide comprising the double zinc finger of the human enhancer binding protein MBP-1 has been determined in solution by nuclear magnetic resonance spectroscopy on the basis of 1280 experimental restraints. A total of 30 simulated annealing structures were calculated. The backbone atomic root-mean-square distributions abo...

The effect of the mechanical deformation of metal-organic frameworks on guest diffusion was investigated by employing molecular dynamics simulations. Two basic deformation modes, uniaxial tensile and shear deformation, were considered. The computed shear modulus of the zeolitic imidazolate framework-8 (ZIF-8) model system was much lower than the Young's modulus, which is in agreement with the e...
