The graphene oxide-zinc oxide (GO-ZnO) nanocomposite was fabricated and applied as the adsorbent to survey the adsorption characteristics of the adsorbates of organic and inorganic water contaminations in an aqueous solution. The synthesized nanocomposite has been characterized using X-ray powder diffraction (XRD) and Scanning electron microscope (...

Background: Considering the numerous nutritional and estrogenic compounds of palm pollen and their effect on sexual function, this study was performed to investigate the effect of palm pollen extract on sexual disorders in postmenopausal women. Methods: In this three-blind clinical trial, 110 postmenopausal women from December 2019 to December 2...

Nanocomposite materials have been successfully applied to remediation of organic and inorganic contaminants from polluted water. The present study investigates the synthesis, characterizations, and adsorptive performances of graphene oxide/SiO2 nanocomposite-based adsorbent. Graphene oxide/SiO2 was used for the adsorption of methylene blue (MB) and...

Background The high prevalence of sexual problems among postmenopausal women needs more attention. Palm pollen extract seemed to help improve menopausal sexual dysfunction with estrogenic and antioxidant compounds. Therefore, this study was performed to investigate the effect of palm pollen on sexual disorders in postmenopausal women. Methods In t...

In this research, the graft copolymer of itaconic acid (IA) onto chitosan (CS) was synthesized in an aqueous medium using ammonium persulfate (APS) as an initiator. Monomer amount, initiator concentration, temperature and reaction time are taken as the process variables and optimized with RSM in order to maximize the graft percentage (106% in the h...

Heavy metals removal from wastewaters and surface waters using low cost and eco-friendly adsorbents is one of the best ways to eliminate these impurities. In the current study, the nanocomposites based on chitosan-g-(acrylamide-co-itaconic acid) and titanium dioxide or silicon dioxide nanoparticles, were synthesized and their antibacterial property...

In this study, the prediction of excess molar volume of ionic liquid + solvent binary system is described using modified two-parameter and three-parameter cubic equation of state (CEoS). The studied binary systems are consisted of 41 ionic liquids, 40 solvents and 5293 data point in the wide temperature range (278.15-353.15 K), ionic liquid mole fr...

Hydrogels are hydrophilic cross-linked polymers that can absorb water several times their weight. In this study, synthesis of hydrogel based on chitosan, acrylamide and itaconic acid is prepared via radical copolymerization studied. To study the effect of initiator concentration, time, temperature, cross-linker concentration, monomer amount and ita...

Graphene oxide (GO) with high oxidation degree (OD) and high adsorption capacity was synthesized easily by modified improved hummer method assisted with ultrasonic at low temperature and short time. Optimization of the synthesis procedure was performed using the response surface method (RSM). Effects of synthesis variables such as Ultrasonic temper...
