A novel polyethersulfone (PES) mixed matrix membranes (MMMs) loaded with iron (Fe) pillared nanoclay was fabricated for efficient rejection of bisphenol (BPA) from water. Low–cost one dimensional (1D) halloysite (FePHNTs), two (2D) bentonite (FePB), and 2D Cloisite 15A (FePC15A) were synthesized via pillaring procedure. XRD, TEM, EDS BET results indicated that the nanoclays successfully pillare...

Understanding how correlations can be used for quantum communication protocols is a central goal of quantum information science. While many authors have linked global measures of correlations such as entanglement or discord to the performance of specific protocols, in general the protocols may require only on correlations between specific observables. Here, we introduce a pairwise measure of co...

PIM-1-based freestanding mixed matrix membranes (MMMs) and thin film nanocomposites (TFNs) were prepared by incorporating porous silica nanosheets (SN) exfoliated SN (E-SN) derived from natural vermiculite (Verm) in the PIM-1 polymer matrix. In addition, functionalized sulfonic acid amine groups (S-SN N-SN, respectively) also used as fillers for preparation of MMMs. The gas separation performan...

Commercialized silicoaluminophosphate-34 (SAPO-34) zeolite was successfully blended in the polyethersulfone (PES) polymer to prepare mixed matrix membranes (MMMs). The CO2 permeability and CO2/CH4 ideal selectivity of 30 wt% SAPO-34/PES MMM at 0.1 MPa 35 °C were 15 barrer 51, respectively. In our previous paper, PES MMMs using laboratory-made SAPO-34 provided both higher than neat membrane. per...

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...

this paper discusses different important gas permeation models such as “maxwell”, “bruggeman”, “lewis-neilson”, and “pal” models to predict “mixed matrix membranes” (mmms) performance. the main parameter considered and discussed is the permeability of hydrogen on carbon nanotubes (cnts)-mmm. for evaluation of the theoretical models, experimental data of permeability for h2 were compared to the ...

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 ...

In this study, novel polycarbonate-titanium oxide nanotubes (PC-TNT) ultrafiltration mixed matrix membranes (MMMs) were fabricated for decontamination of Cd2+ and Cu2+ metal ions from aqueous solution. The weight percent of TNTs in the polycarbonate membrane matrix was changed from 0 to 15. The synthesized neat PC membrane and PC-TNTs MMMs were characterized with respect to structural morpholog...

Highly permselective and durable membrane materials have been sought for energy-efficient C3H6/C3H8 separation. Mixed-matrix membranes (MMMs) comprising a polymer matrix metal–organic frameworks (MOFs) are promising candidates this application; however, rational matching of filler-matrix is challenging their separation performances need to be further improved. Here, we propose novel strategy “d...

The industrial advancement in the textile industry has caused negative environmental impacts because of large amount dye wastewater effluent. treatment can be conducted using adsorption, biological treatment, and flocculation-coagulation processes. However, all these methods involve chemical additions, which may increase operational cost process. To overcome this problem, membrane separation te...
