Abstract—The purpose of this paper is to examine gas transport behavior of mixed matrix membranes (MMMs) combined with porous particles. Main existing models are categorized in two main groups; two-phase (ideal contact) and three-phase (non-ideal contact). A new coefficient, J, was obtained to express equations for estimating effect of the particle porosity in two-phase and three-phase models. ...

Due to their stable chemical properties and complex structures, dyes are difficult be removed from water. Herein, a ZIF-67/SA@PVDF (ZSA3@PVDF) mixed matrix membrane has been fabricated by incorporating silicon aerogel (SA) zeolitic imidazolate framework material 67 (ZIF-67) nanoparticles in polyvinylidene fluoride (PVDF) for the removal degradation of The influence SA ZIF-67 on morphology struc...

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...

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 ...

Let G be a nonsingular connected mixed graph. We determine the mixed graphs G on at least seven vertices with exactly two Laplacian eigenvalues greater than 2. In addition, all mixed graphs G with exactly one Laplacian eigenvalue greater than 2 are also characterized. c © 2006 Elsevier Ltd. All rights reserved.
