The main aim of the present study is to evaluate influence multi-walled carbon nanotubes (MWCNTs) and TiO2 nanoparticles (NPs) on lubricant fluid flow within natural gas turbine meters. In light this purpose, disparate concentration NPs (0.1, 0.2, 0.3 wt%), various volume rates 0.14, 0.35, 0.12 cm3S were employed for experimental analyses. facet simulation, Gambit software version 2. 4. 6 mesh ...

We fabricated a novel vascular endothelial growth factor (VEGF)-loaded poly(lactic-co-glycolic acid) (PLGA)-nanoparticles (NPs)-embedded thermo-sensitive hydrogel in porcine bladder acellular matrix allograft (BAMA) system, which is designed for achieving a sustained release of VEGF protein, and embedding the protein carrier into the BAMA. We identified and optimized various formulations and pr...

The aim of the work was to investigate the interaction between borate capped gold nanoparticles (NPs) and the rat brain synaptosomal plasma membranes (SPM), as well as the effects of these NPs on SPM Na/KATPase and Mg-ATPase activity. The changes in the UV-vis spectra of NPs and SPM assembly suggested the agglomeration and precipitation of NPs. FTIR measurements indicated that both protein –SH ...

Thin-film composite (TFC) membranes show great potential in dye nanofiltration but their performance still required further improvement. In this work, ultra-small EMT zeolite nanocrystals were embedded into the interfacial polymerized polyamide (PA) layer supported on porous nylon via spray dispersion method and used separation. Ultra-small nanosized crystals with plate-like morphology synthesi...

Herein, graphene oxide nanosheets (GO) were synthesized and employed as an additive at various proportions to fabricate a novel cation exchange membrane based on grafted cellulose acetate with sodium 4-styrenesulfonate (GCA) via solution casting method for direct methanol fuel cell (DMFC) applications. The structure of composite membranes has been examined using FTIR, TGA, SEM, DSC. physicochem...

the gas separation performance of commercial ceramic titania and hybrid silica (hybsi®) membranes was assessed using the gas permeation and permporometry methods. results indicated that the hybsi® membranes have a hybrid surface containing regions covered by a polymeric matrix and others with inorganic pores. these membranes have high h2 selectivity, which increases significantly with temperatu...

Abstract: For increasing the efficiency of omega-3 production, effect span-85 surfactant as a hydrophobic agent (0, 1, 2, 3 and 4 wt%) on formation porous structure in sub-layer PVDF membrane was studied. Also, cross-sectional morphology membranes analyzed using scanning electron microscopy (SEM) surface property evaluated contact angle test. The capacity to concentrate examined by filtration l...

To improve the CO2/N2 separation performance, mixed-matrix carbon molecular sieve membranes (mixed-matrix CMSMs) were fabricated and tested. Two carbon-based fillers, graphene oxide (GO) activated (YP-50F), separately incorporated into two polymer precursors (Matrimid® 5218 ODPA-TMPDA), resulting CMSMs demonstrated improved CO2 permeability. The improvement afforded by YP-50F was more substanti...

Introduction: Bismuth-based nanoparticles having high atomic number and electron density, besides of being utilized as CT contrast agent, stand as a strongly proposed method for dose enhancement in radiotherapy. Embedded nanoparticle in polymer gel dosimeter poses the first step to assess the dose enhancement capability in nanoparticles. To this end, MAGICA gel dosimeter, whic...
