Hierarchical 3D ZnIn2S4/graphene (ZnIn2S4/Gr) nano-heterostructures were successfully synthesized using an in-situ hydrothermal method. The dual functionality of these nano-heterostructures i.e. for solar hydrogen production and lithium ion batteries has been demonstrated for the first time. The ZnIn2S4/Gr nano-heterostructures were optimized by varying the concentrations of graphene for utmost...

BACKGROUND Iron (Fe) deficiency anemia remains the largest nutritional deficiency disorder worldwide. How the gut acquires iron from nano Fe(III), especially at the apical surface, is incompletely understood. OBJECTIVE We developed a novel Fe supplement consisting of nanoparticulate tartrate-modified Fe(III) poly oxo-hydroxide [here termed nano Fe(III)], which mimics the Fe oxide core of ferr...

A new approach for the synthesis of Prussian blue nanoparticles using the cationic surfactant Cetyl Pyridinium Chloride (CPC) as capping agent has been developed in the present work. Powder X-ray diffraction, transmission electron microscopy, UV–vis absorption spectra, and IR spectroscopy were employed to characterize the product. The TEM image showed that the Prussian blue nanoparticles with d...

In the present study, a simple, efficient and fast synthetic strategy was reported for the green biosynthesis of silver nanostructures (i.e. nanoroads and nanoparticles) by the extract of Suaeda Acuminata plant, without any catalyst, template or surfactant. Aqueous extracts were obtained by maceration and microwave assisted extraction (MAE) methods. In MAE procedure, the effec...

Sildenafil citrate (SLD) is a selective cyclic guanosine monophosphate-specific phosphodiesterase type 5 inhibitor used for the oral treatment of erectile dysfunction and, more recently, for other indications, including pulmonary hypertension. The challenges facing the oral administration of the drug include poor bioavailability and short duration of action that requires frequent administration...

curcumin is a hydrophobic polyphenol extracted from the plant curcuma longa with establishedanticancer properties. however, curcumin benefits have been impaired by its very low watersolubility, low absorption, rapid metabolism and clearance from the body. recently,nanotechnology promises to be helpful in development of drugs delivery systems by recentadvances in macromolecular design of nanocar...

Visible spectrophotometry is used to study the kinetics of ligand exchange in the system Ni(salpn)/H2salen with or without triethylamine (NEt3) and H2O in dimethylformamide (DMF) solvent at 25 ± 0.1 °C and 0.01 M NaNO3 [H2salen and H2salpn are N,N’-ethylen-bis(salicylaldimine) and N,N’-propylen-bis(salicylaldimine), respectively]. It was found that the reaction rate is of the first-order with r...
