Engineered interfacial interlocking structure also serves as a bridge to accelerate the gas transport from polymeric region towards pore entrance. Selective enhancement MMM CO2 once combined with CH4 paves ways toward promising perspective for pre-combustion capture. adhesion Membranes (MMMs) has been ...

In this work, we synthesized an ionic liquid (IL)/metal organic framework (MOF) composite, 1-ethyl-3-methylimidazolium acetate/copper-1,3,5-benzenetricarboxylate ([EMIM][OAc]/CuBTC) and used it as a filler in polymer, Pebax, to fabricate novel IL/MOF/polymer mixed matrix membranes (MMMs). CuBTC/Pebax [EMIM][OAc]/CuBTC/Pebax MMMs having different loadings of 10, 15, 20 wt.% were prepared by solu...

Effective and economical carbon dioxide-methane separation (CO2/CH4) is highly desirable in several industries such as sweetening natural gases renewable gas (RNG) from biogas landfills. Among the different technologies, membrane has been shown to have lower cost of production CH4 losses. In this study, Zeolitic Imidazole Frameworks (ZIF-8) crystals with sizes varying 45 nm 450 were synthesized...

Abstract Membrane‐based separations offer energy‐efficient solutions for various applications, but commercial polymer membranes show limited performance and stability. Mixed‐matrix (MMMs), incorporating nanoporous inorganic materials in matrices, have been of great interest to circumvent these polymer‐specific issues. However, reaching the percolation threshold is crucial leverage high‐performi...

The atom transfer radical polymerization (ATRP)-based continuous assembly of polymers (CAP) is a promising approach for fabricating thin film composite (TFC) membranes high flux. Here, we report the preparation CO2-selective TFC mixed matrix (MMMs) by incorporating different amounts [Cu24(m-bdc)24(EG)3(DMF)12] (EG3-MOP) nanocages (e.g., 2.5, 5, and 10 wt%) as CO2-philic fillers in poly(poly(eth...

Polyurethane (PU)-ZnO mixed matrix membranes (MMM) were fabricated and characterized for gas separation. A thermogravimetric analysis (TGA), a scanning electron microscope (SEM) test and an atomic-force microscopy (AFM) revealed that the physical properties and thermal stability of the membranes were improved through filler loading. Hydrogen Bonding Index, obtained from the Fourier transform in...

Due to the complexity of real-world applications, the number of databases and the volume of data have increased tremendously. Discovering qualitative and quantitative patterns from databases in such a distributed information-providingenvironment has been recognized as a challenging task. In response to such a demand, data mining and data warehousing techniques are emerging to extract the previo...

Mixed matrix membranes (MMMs) are a strong alternative to the conventional polymeric which suffer from trade-off between selectivity and gas permeability. Considering existence of large number metal–organic frameworks (MOFs) polymers, computational screening MOF/polymer MMMs is strongly desired explore their upper limits in various separation processes before experimental efforts. In this work,...

In order to promote the selective water permeation through porous filler, hydrophilic MOF-801 crystals with superior water adsorption ability were incorporated into chitosan (CS) matrix to fabricate MOF-801/CS mixed matrix membranes (MMMs) for pervaporation dehydration of ethanol. Both the experimental and molecular simulation results confirm the selective adsorption of water molecules in MOF-8...
