Morphology Controlled Deposition of Vanadium Oxide (VO) Nanoparticles on the Surface of Highly Reduced Graphene Oxide for the Photocatalytic Degradation of Hazardous Organic Dyes.

Semiconducting nanomaterials based heterogeneous photocatalysis represent a low-cost, versatile technique for environmental remediation, including pollution mitigation, energy management and other environmental aspects. Herein, we demonstrate the syntheses of various heterogeneous photocatalysts based on highly reduced graphene oxide (HRG) and vanadium oxide (VO)-based nanocomposites (HRG-VO). Different shapes (rod, sheet and urchin forms) of VO nanoparticles were successfully fabricated on the surface of HRG under solvo-/hydrothermal conditions by varying the amount of water and ethanol.

Enhanced photodegradation of methylene blue from aqueous solution using Al-doped ZnS nanoparticles.

The post-transition semiconducting material of pure zinc sulfide (ZnS) and various concentrations of aluminum (Al) (2.5 wt%, 5.0% wt, 7.

Exploiting of Green Synthesized Metal Oxide Nanoparticles for Spectrophotometric Determination of Levofloxacin, Cephalexin, and Cefotaxime Sodium in Commercial Products.

In this study, two metal oxide nanoparticles NiO and MnO were synthesized from green sources () extract and ( peel extract, respectively. The optical and physical properties of the synthesized nanoparticles were characterized using spectroscopic and microscopic techniques. Simple, precise, and new spectrophotometric probes were suggested for the determination of three cephalosporin antibiotics, including levofloxacin (LVX), cephalexin (CPX), and cefotaxime sodium (CTX) in their pure form and commercial products.

Preparation of a carboxymethylcellulose-iron composite for uptake of atorvastatin in water.

Many water bodies are being contaminated by atorvastatin, which has certain side effects and problems on healthy individuals through contaminated water. For this purpose, effective and selective carboxymethylcellulose macromolecule iron composite nanoparticles were synthesized by green methods, characterized and used for uptake of atorvastatin drug residue from water. Atorvastatin in water was analyzed by HPLC using Aqua C (250 mm × 46 mm id) column and buffer-ACN (35:65, v/v) as eluent.

Modeling of fenuron pesticide adsorption on CNTs for mechanistic insight and removal in water.

Inexpensive multi-walled carbon nanotubes (MCNTs) were prepared with 10-40 nm particle sizes and 9.0 mg surface area. Fenuron pesticide was removed in water using these CNTs with 100.

Spectrofluorimetric analysis of gemifloxacin mesylate in pharmaceutical formulations.

A simple, rapid and highly sensitive spectrofluorimetric method was developed for determination of gemifloxacin mesylate (GFX) in tablets. The method is based on measuring the native fluorescence of GFX in isopropanol at 400 nm after excitation at 272 nm. The fluorescence-concentration plot was rectilinear over the range of 0.
