“…Low operational cost, relatively small footprint, and compliance with environmental regulations are the major benefits of polymeric membranes. Organic systems are less chemical and temperature stable than inorganic membranes, but are more versatile in providing different porous structures (Ng et al, 2010;Sforça et al, 1999).…”

-In relation to some inorganic membranes, polymeric membranes have relatively low separation performance. However, the processing flexibility and low cost of polymers still make them highly attractive for many industrial separation applications. Polymer-inorganic hybrid membranes constitute an emerging research field and have been recently developed to improve the separation properties of polymer membranes because they possess properties of both organic and inorganic membranes such as good hydrophilicity, selectivity, permeability, mechanical strength, and thermal and chemical stability. The structures and processing of polymer-inorganic nanocomposite hybrid membranes, as well as their use in the fields of ultrafiltration, nanofiltration, pervaporation, gas separation and separation mechanism are reviewed.

“…MMMs make use of the benefits of the transport properties of both inorganic and organic materials in the polymer matrix that provide higher strength, permselectivity and antifouling characteristics compared to bare polymeric membranes. Some examples are polymeric membranes modified with zeolite [19], zero-valent metals [20], carbon nanotubes [21], metal oxide nanoparticles [22], and fullerenes [23].…”

ElsevierGarcía Ivars, J.; Iborra Clar, MI.; Alcaina Miranda, MI.; Van Der Bruggen, B. (2015). Comparison between hydrophilic and hydrophobic metal nanoparticles on the phase separation phenomena during formation of asymmetric polyethersulphone membranes. ABSTRACTInorganic nanoparticles have been applied as additive in membrane synthesis for improving different properties from the base polymer such as hydrophilicity, fouling resistance or permselectivity. To investigate the changes caused by the presence of the inorganic nanoparticles in the formation of the membrane structure, two different metallic compounds with opposite hydrophilicity were used as additives: hydrophilic zinc oxide (ZnO) and hydrophobic tungsten disulphide (WS 2 ). For this purpose, the effect of these metal nanoparticles at ultra-low concentrations (0.05 and 0.25 wt% metal nanoparticles/polymer ratio) in the preparation of flat-sheet membranes based on polyethersulphone (PES) by immersion-precipitation method was investigated. Nmethyl-2-pyrrolidone (NMP) was used as solvent. The influence of both metal nanoparticles on the characteristics and permselective properties of PES membranes was studied with microscopic observations, contact angle measurements, and filtration experiments. Although the incorporation of metal nanoparticles could turn the system into thermodynamically unstable, the demixing process during formation of membranes was slightly delayed, suppressing the macrovoid formation (remarkably using WS 2 ).Regardless the nature of the metal nanoparticles, results showed an overall improvement in membrane hydrophilicity and permselectivity by adding metal nanoparticles compared to the control PES membrane, demonstrating that the behaviour of both metal nanoparticles at ultra-low concentrations was very similar.

“…[1À5] Another application of nanoparticles is in the synthesis of polymeric membranes that can be used for waste treatment, filtration and gas separation. [6] In a recent review, several industrial applications have been highlighted, such as inert additives, biomimetic materials, antimicrobial compounds and pigments. [7] Nanoparticles have gained popularity for their application in molecular biology, especially as scaffolds for a variety of biological molecules, such as antibodies, DNA, RNA and proteins.…”

This study describes a novel biological route for the biosynthesis of silver oxide nanoparticles utilising the aqueous extract of Callistemon lanceolatus D.C. leaves. Formation of silver oxide nanoparticles was confirmed by UVÀvisible spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopeÀenergy dispersive X-ray spectroscopy and X-ray diffraction spectroscopy analysis. The biologically synthesised silver oxide nanoparticles were found to be 3À30 nm in size with spherical and hexagonal shape by high-resolution transmission electron microscope analysis. Furthermore, the biogenic silver oxide nanoparticles demonstrated significant (p < 0.05) dose-dependent antioxidant activity in various in vitro antioxidant methods. These particles also exhibited significant (p < 0.05) dosedependent and time-dependent cytotoxic activity towards brine shrimp nauplii. Moreover, the reported method is a simple, cost-effective and eco-friendly approach for the synthesis of silver oxide nanoparticles with useful pharmacological properties.
