Mixed-matrix membranes (MMMs) are that composed of polymers embedded with inorganic particles. By combining the fillers, improvements can be made to permeability compared pure polymer due new pathways for gas transport. However, such as hyper cross-linked (HCP), also help reduce physical aging MMMs a glassy matrix. Here we report synthesis two novel HCP based on Friedel–Crafts reaction between ...

Membrane separation is a promising technology for hydrogen purification or carbon capture due to its high energy efficiency. However, the trade-off between permeability versus selectivity and gradual reduction of membrane caused by physical aging restrict further development glassy membranes. Poly(1-trimethylsilyl-1-propyne) (PTMSP), highly permeable polymer, limited low fast properties. Mixed ...

Researchers are currently considering membranes separation processes due to their eco-friendly, process simplicity and high efficiency. Selecting a suitable efficient operation is the primary concern of researchers in field industries. In recent decades, polymeric inorganic industry have made significant progress. The been challenged competitiveness permeability selectivity factors. A combinati...

Polysulfone (PSF)-based mixed-matrix membranes (MMMs) were developed through incorporation by solvent casting of poly(ethylene glycol)-grafted carbon nanotubes (PEG-g-CNTs) into the polymer matrix. Single-gas permeability and respective perm-selectivity values resulting MMMs for CO2, CH4, N2 along with mixed-gas selectivities determined at various temperatures pressures. The performance was fur...

Mixed matrix membranes (MMM) incorporating metal-organic framework (MOF) fillers have gained increasing attention in addressing environmental and sustainability challenges. Hierarchical materials combining pore sizes of different length scales are expected to facilitate molecular diffusion mass transfer for the optimization catalysis separation processes. Herein, a novel preparation method hier...

Functionalized and reduced graphene oxide nanosheets with octadecylamine (rGOODA) were incorporated in polydimethylsiloxane (PDMS) membranes to be used pervaporation for removal of toluene from water. The properties the functionalized characterized by FTIR, XRD, Raman, SEM, TGA analyses. prepared mixed matrix (MMMs) using contact angle, AFM, SEM-EDX, TGA, solvent uptake tests. contained (rGO) r...

The carbon dioxide (CO2) separation can be enhanced by using modified materials like a deep eutectic solvent (DES) mesoporous silica SBA-15 in polymeric support i.e polysulfone via mixed matrix membranes (MMMs). pure and DES are potential candidates for the CO2 capturing their combination has not been reported yet. In this work, fresh was synthesized combining equal concentrations of Decanoic a...

ConspectusConventionally, the virtue of porosity is only given to porous solids. Metal Organic Frameworks (MOFs), carbon materials, or zeolites are some examples. However, processing these solids not a straightforward task. Here, we discuss how endow (MOFs) with liquid phase processability. More specifically, show that surface modification MOF crystals can lead formation liquids (PLs) be furthe...

We introduce and study (metrically) quarter-stratifiable spaces and then apply them to generalize Rudin and Kuratowski-Montgomery theorems about the Baire and Borel complexity of separately continuous functions. The starting point for writing this paper was the desire to improve the results of V.K. Maslyuchenko et al. [MMMS], [MS], [KM], [KMM] who generalized a classical theorem of W.Rudin [Ru]...
