The comprehensive elastic properties of Zeolitic Imidazolate Frameworks (ZIF-1 to ZIF-4) have been computed using density functional theory (DFT). We employed the periodic CRYSTAL14 code to calculate the single-crystal elastic coefficients (Cij) at the B3LYP level of theory. While the chemical compositions of ZIFs-1 to -4 are the same, each structure features a distinct network topology, crysta...

Abstract Poly (m-phenylene isophthalamide) (PMIA) membranes are prepared via evaporating part solvent of the casting solution before its nonsolvent-induced phase separation. Zeolite imidazolate framework-8 (ZIF-8) is added into PMIA as an inorganic filler to improve filtration capability membrane. The structure composite characterized by scanning electron microscopy (SEM), Zeta-potential analyz...

Complex metal-organic frameworks used as precursors allow design and construction of various nanostructured functional materials which might not be accessible by other methods. Here, we develop a sequential chemical etching and sulfurization strategy to prepare well-defined double-shelled zinc-cobalt sulfide (Zn-Co-S) rhombic dodecahedral cages (RDCs). Yolk-shelled zinc/cobalt-based zeolitic im...

Aktif paketleme uygulamaları gıda raf ömrünü uzatarak israfını azaltmayı hedeflemektedir. Geliştirilen malzemelerinin biyobozunur, sürdürülebilir ve yenilenebilir kaynaklardan olması çevre kirliğinin azaltılması doğal kaynakların korunabilmesi için gereklidir. Bu nedenle, bu çalışmada antioksidan antimikrobiyal özelliklere sahip bir özüt olan kurkumin, zeolitik imidazol çerçeve-8 (K-ZİF-8) nano...

Exploring the kinetics of metal–organic framework crystallization is crucial in order to design novel synthesis methods benefiting from far-from-equilibrium conditions, such as flow, microfluidic, or gel-phase reactors. Herein we focus on zeolitic imidazolate frameworks (ZIFs) obtained reaction 2-methylimidazolate and zinc ions a model system. The room-temperature carried out pure water solvent...

Zeolitic imidazolate frameworks (ZIFs) 7 and 9 are excellent candidates for CO2 adsorption and storage. Here, high-pressure X-ray diffraction is used to further understand their potential in realistic industrial applications. ZIF-7 and ZIF-9 are shown be able to withstand high hydrostatic pressures whilst retaining their porosity and structural integrity through a new ferroelastic phase transit...

The behavior of the crystal structure zeolitic imidazolate framework ZIF-75 under pressure was studied by means periodic density functional theory methods. Experimentally, it shown that this material is tetragonal, space group I41/a at room temperature. However, according to calculations, zero temperature monoclinic, C2/c. Irrespective symmetry material, results show exhibits a negative linear ...
