Biogenic synthesis of ZnO and Al2O3 nanoparticles using Camellia sinensis and Origanum vulgare L. leaves extract for spectroscopic estimation of ofloxacin and ciprofloxacin in commercial formulations.

The current study describes the biogenic synthesis of two metal oxides zinc oxide (ZnO), aluminum oxide (Al2O3) nanoparticles using Camellia sinensis, and Origanum vulgare L. leaves extract, respectively. The synthesized metal oxide nanoparticles were investigated using spectroscopic and microscopic techniques to confirm the formation of their nanostructures.

Thermodynamics, simulation and chiral recognition mechanism of two asymmetric center quinolone.

A novel antibacterial quinolone was prepared with two chiral centers. For medicinal safety purposes, the four stereoisomers of the molecule are separated by HPLC using a Chiral (+)-Crownpack column (25 cm × 0.46 cm, 5.

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.

Enantioselective degradation of dufulin pesticide in water: Uptake, thermodynamics, and kinetics studies.

Kudzu (Pueraria thunbergiana) plant extract impregnated sediments were used for abiotic and biotic uptakes and biodegradation. The optimized conditions were 25 μg L concentration, 7 days for abiotic uptake and 56 days for biotic uptake and biodegradation, dose 2 g L , 7 pH, and 35°C temperature. The amount removed of dufulin was 32.

Application of Composite NanoMaterial to Determine Phenols in Wastewater by Solid Phase Micro Membrane Tip Extraction and Capillary Electrophoresis.

Composite nanoparticles were used in solid phase micro membrane tip extraction and capillary electrophoresis to determine phenol and -amino-phenol in wastewater. The optimized conditions were 100 g/L concentration, 40 min contact time, 11 pH, 5 mg/mL nanoparticles amounts, 60 min desorption time, 9 desorption pH and 298 K temperature. Capillary electrophoresis conditions were phosphate buffer (15 mM, pH 7.
