Functional polymeric membranes with antibacterial properties have gained significant importance in many applications. Silver NPs offer advantage over other materials for their effective and being safer humans at low concentrations. The synthesis of silver may not always be environmental friendly incorporation the polymer is usually a multistep process. In this study, PVDF/PVP/AgNPs electrospun ...

Using of nanocomposite membranes composed of polymer and inorganic nanoparticles is a novel method to enhance gas separation performance. In this study, membranes were fabricated from polyester (PE) containing silica (SiO2) nanoparticles and gas permeation properties of the resulting membranes were investigated. Morphology of the membranes, SiO2 distribution a...

asymmetrically mixed matrix matrimid-mil-53 membranes with silicone cover layer were fabricated. for better understanding of membrane fabrication process, three main parameters of fabrication, matrimid concentration, silicone concentration and weight percentage of metal organic framework (mil-53) particles, were optimized by an experimental design method. cross-section sem images were used to s...

objective(s): this study aimed to determine the possible toxicity of cuo nanoparticles (nps) on oncorhynchus mykiss by evaluating hematological parameters.materials and methods: fish were sampled and treated in 4 aquariums containing the concentration ranges of 1, 5, 20 and 100 ppm of cuo nps. there was one control group (no cuo nps) and three replicates. the physicochemical properties of water...

objective(s): an efficient vaccine against tb is an urgent need. tb peptides are safe candidate but they are weak immunogens and needs to be potentiated by adjuvant/delivery systems. the main purpose of the present study was to determine the potential of cht based nps containing esat-6 antigen of m. tuberculosis for inducing mucosal and systemic immune responses after intranasal and subcutaneou...

Background: Natural organic matter (NOM) in drinking water sources has always been regarded as a precursor for the formation of trihalomethanes (THMs), haloacetic acids (HAAs), and carcinogenic properties. This study aimed to fabricate characterize nanohybrid ultrafiltration membrane (PSF/ZnO) evaluate its efficiency NOM removal from water. Methods: Nanohybrid membranes with ratios 0, 1, 2, 3 4...

In the present paper, an experimental assessment was performed on the transient thermal performance of a heat sink filled by a phase change material (PCM) and PCM embedded with carbon nanofibers (CNFs) and titania (TiO2) nanoparticles as nanostructured materials. In order to enhance the thermal conductivity of PCM, CNFs and TiO2 nanoparticles at different loadings (0.5wt. % and 2 wt.% of CNFs a...

The possibility of producing stable oil-in-water (O/W) emulsions containing oil droplets surrounded by multiple layer interfacial membranes from food grade ingredients has been demonstrated. These emulsions were produced using a three stage process that relies on the adsorption of charged biopolymers to oppositely charged surfaces. Emulsions (0.5 wt % corn oil, 0.1 wt % lecithin, 0.0078 wt % ch...

the rapidly increasing interest in functional materials with reversibly switchable physico- chemical properties has led to significant work on the development of stimuli responsive membranes. thermotropic liquid crystals with their exceptional properties have potentials for drug-delivery applications. thermoresponsive liquid-crystal-embedded membranes were investigated for the purpose of develo...
