In this research, CMC/MMT nano composite was prepared using the free radical polymerization method and evaluated as Arsenic ions removal adsorption from an aqueous solution. We used Design expert (CCD) to remove Ions optimally. SEM, XRD FTIR analyses were determine adsorbent properties. The experimental design done with four time variables (25–40min), concentration (0.5–2 ppm), dose (0.05-2gr) pH (4–8). interaction combined effects of by analysis variance (ANOVA) table. A quadratic...
Abstract The transesterification process with potassium hydroxide (KOH) catalyst and the methanol supercritical were evaluated by Aspen HYSYS software. Castor oil used as feed alcohol. In order to accomplish verification, simulation results compared a laboratory research. For economic analysis, these transferred Economic Analyzer Piping equipment cost calculated for two processes. Additionally, direct indirect costs of processes estimated.
Fossil fuels are the main sources of human energy, but their combustion releases toxic compounds sulfur oxide. In oil industry, using optimal methods to eliminate from fossil is a very important issue. this study, performance montmorillonite/graphitic carbon nitride (a new hybrid nanostructure) in increasing biodesulfurization activity Rhodococcus erythropolis IGTS8 was investigated. X-ray diffraction, Fourier-transform infrared spectroscopy, field emission scanning electron microscopy and...
The protection of steel against corrosion by nano-glass flake containing coatings has been evaluated in this article. Nano-glass was incorporated into epoxy vinyl ester resin mechanical agitation, homogenizer and sonication process. dispersion morphology agglomeration degree nanoadditives were analyzed optical microscopy, scanning electron microscopy energy-dispersive X-ray spectroscopy. effect micro on anticorrosion performance also compared a salt spray chamber. influence the thermal...
In the present work, attempts were made to investigate thermal and mechanical properties of melt-processed poly(ethylene terephthalate) (PET)/poly(ethylene 2,6-naphthalate) (PEN) blends its nanocomposites containing graphene by using differential scanning calorimetry tensile test experimenting. The results showed that crystallinity, which depends on a blend ratio, completely disappeared in composition 50/50. By introducing PET, even low concentrations, crystallinity samples increased, while...
Abstract Two kinds of hydrogels based on acrylic acid (AA) and acrylamide (AAm) without with 2‐acrylamido‐2‐methylpropane sulphonic (AMPS) were synthesized by radical polymerization using ethylene glycol dimethylacrylate as a crosslinker, to form double network (DN) triple (TN) interpenetrating polymer networks (IPN) gels, respectively. Fourier transform infrared spectroscopy (FTIR) presented evidence for the formation polyacrylic (PAA)/polyacrylamide (PAAm) IPN gels Michael‐type grafting...
This study is concerned with morphological and rheological behavior of several systems based on poly(ethylene terephthalate) (PET), poly(ethylene‐2,6‐naphthalene) (PEN), PET/PEN blend, their graphene‐filled nanocomposites. The composites were prepared by using a melt‐mixing method analyzed scanning electron microscopy transmission techniques. It was observed that the graphene nanosheets almost distributed uniformly, especially in blend matrix. applied mixing easily able to disperse...
The structure of β-coronavirus MERS-CoV S1-CTD demonstrated an interesting subject how two structurally similar viral RBDs recognize different protein receptors. Same as SARS-CoV, the S1-CTD, viruses also contains subdomains, but, in contrast to loop-dominated MERS-CoV, RBM a 4-stranded antiparallel β-sheet, showing relatively flat surface bind DPP4. sequences were obtained from NCBI web sites, and proteins COVID-19, such sequences, applied for analyzing conserved domain. Some utilized...
: The main goal of this work was to investigate the effects silane-modified graphene nanosheets (MGNS) and modified nanoglass flakes (MNGF) on physical mechanical properties vinyl-ester resin (VER) composites. surface modification evaluated about these composites' behavior by techniques such as water absorption, tensile, three-point bending, dynamic thermal analysis (DMTA). analytical data revealed that silane functionalized nanocomposites improved interface between matrix. It found could...
Abstract The aim of this work is synthesis a novel nanocomposite containing Polylactide (PLA) and polyamide 6 (PA6) reinforced with graphene oxide (GO) poly ethylene-butyl acrylate-glycidyl methacrylate) (PTW) compatibilizer during solvent-based method. For purpose, GO was added to the 0.1, 0.3, 0.5, 0.7 1 phr. Morphology, rheology mechanical properties nanocomposites were studied scanning electron microscopy (SEM), transmission (TEM) (DMTA) which showed rougher fracture surface due presence...
In the present work, attempts were made to investigate reinforcement and treatment effect of GF on morphological rheological behaviour GF/epoxy vinyl ester composites. was incorporated into epoxy resin by sonication, mechanical agitation. Rheological properties studied as a function particle size distributions.
