Mixed matrix membranes (MMMs) have gained much interest in the last two decades to be used as water, waste and gas separation membranes. MMMs combine polymer inorganic filler improve performances of pure polymeric However, choice should conducted carefully avoid formation microvoids that can decrease membrane’s performances. Hence, this study synthesis characterization Zeolitic Imidazolate Fram...

Metal organic framework (MOF) membranes have gained more attentions due to their abilities in various applications gas and liquid separations. The majority of works are related Zeolite imidazolate frameworks-8 (ZIF-8). This is often attributed its high stability, easy synthesis, good separation. They a significant interest scientists the aptitude be utilized other separations applications. Inde...

A molecular simulation study is reported for biofuel purification in six zeolitic imidazolate frameworks (ZIF-8, -25, -71, -90, -96 and -97) with different functional groups. For pure ethanol and water, the predicted adsorption isotherms agree fairly well with experimental data. Hydrogen bonding has an important effect on the adsorption of ethanol and water. In hydrophilic ZIFs (ZIF-90, -96 and...

We report here the first example of ZIF materials synthesized in aqueous solution. The synthesis was performed at room temperature and typically took several minutes compared to hours and days in non-aqueous conditions. The obtained product were ZIF-8 nanocrystals having size of ~85 nm and showed excellent thermal, hydrothermal and solvothermal stabilities.

In this work, a new theranostic nanoplatform is developed to construct an anticancer drug carrier by integrating the distinct advantages of upconversion nanoparticles (UCNPs) and metal organic frameworks (MOFs) encapsulated with a targeting ligand. Here NaYF4:Yb3+,Er3+ is chosen as an upconversion nanoparticle for its high luminescence properties. Then, folic acid encapsulated Zeolitic Imidazol...

Double-layered zeolitic imidazolate framework (ZIF) membranes were fabricated inside polyimide P84 hollow fibers by a step-synthesis conducted by microfluidic technology and applied to pre-combustion gas separation. Our hypothesis, based on the information provided by a combination of molecular simulation and experiments, is that a CO2 adsorption reduction on the surface of the ZIF-9 would enha...

The objective of this work is to develop a new class of nanocomposite ultrafiltration (UF) membranes with excellent solute rejection rate and superior water flux using zeolitic imidazolate framework-8 (ZIF-8) and multi-walled carbon nanotubes (MWCNTs). The effect of ZIF-8 and MWCNTs loadings on the properties of polyvinyldifluoride (PVDF)-based membrane were investigated by introducing respecti...

We evaluate the self-diffusion and transport diffusion of interacting particles in a discrete geometry consisting of a linear chain of cavities, with interactions within a cavity described by a free-energy function. Exact analytical expressions are obtained in the absence of correlations, showing that the self-diffusion can exceed the transport diffusion if the free-energy function is concave. ...

Metal-organic frameworks have attracted a great deal of attention for future applications in numerous areas, including gas adsorption. However, order them to reach their full potential substrate provide an anchor may be needed. Ideally, this should environmentally friendly and renewable. Cellulose nanofibrils show area. Here we present hybrid material created from the self-assembly zeolitic imi...
