The biosynthesized magnesium oxide nanoparticles were pigeon-holed with X-ray diffraction (XRD), ultraviolet-visible (UV-Vis) spectrophotometer, scanning electron microscope (SEM), and photoluminescence spectrometer (PLs) antibacterial activity. Datura stramonium leaves extract has been used in the present work,; which medicinal value, we have synthesized from both chemical biosynthesis techniq...

The synthesis of semiconductor nanoparticles is an expanding research area due to the potential applications in the development of nanotechnologies. Especially, biosynthesized nanoparticles have become an important branch of nanotechnology. In the present work, we describe a low-cost and simple procedure for biosynthesis of Zinc oxide nanoparticles (ZnO NPs) using Pyrus Pyrifolia leaf extract. ...

structural properties and chemical composition change the photocatalytic activity in tio2-sio2 nanopowder composite. the sio2-tio2 nanostructure is synthesized based on sol–gel method. the nanoparticles are characterized by x-ray fluorescents (xrf), x- ray diffraction (xrd), tunneling electron microscopy (tem), field emission scanning electron microscopy (fe-sem), uv-vis. spectrophotometer and ...

The isolation and detection of flavonoids in the extract Daruju root has been carried out. obtained from maceration modification using 96% ethanol, ethanol extraction result is concentrated with a rotary evaporator then evaporated above water bath until thick obtained. resulting was further separated separating funnel diethyl ether n-butanol as solvents. Then tested for plavonoid preliminaries ...

This research reported Cu2+ un-doped (pure) and doped ZnO semiconductors with variations in concentrations of 3%, 4% 5% through the sol gel method which aims to determine morphology optical properties has been investigated. In addition, film was coated using doctor blade addition chlorophyll as a dye sensitizer. Morphological elemental content tests were carried out SEM EDS. The analyzed by tak...

Determination of the true surface areas, concentrations, and particle sizes of gold nanoparticles (AuNPs) is a challenging issue due to the nanoparticle morphological irregularity, surface roughness, and size distributions. A ligand adsorption-based technique for determining AuNP surface areas in solution is reported. Using a water-soluble, stable, and highly UV-vis active organothiol, 2-mercap...

In this study, the effect of pretreatment and solid-state fermentation (SSF) on tempeh protein content has been studied. Pretreatment SSF are important processes for producing high-quality tempeh. Based results analysis using a UV-Vis spectrophotometer at ?max = 540 nm, it is known that both cause reduced content. causes total (w/w) to decrease rapidly from 1.05% 0.82%, while dissolved 0.57% 0....

This study consists of two parts; the first part is measuring temperature and relative humidity twenty pharmacy shops refrigerators in Erbil city. The inside nine types different drug bottles also measured. results show that places are higher than standard (25C) (35%) drugs. would be if compared with environment temperature. Second parts, optical properties studied by using UV-VIS spectrophoto...

Eugenia jambolana is a traditional medicinal plant of low reaches of Kumaun Himalaya. The tribal inhabitants of Himalaya use the plant for curing diabetes and abdominal pain of peptic ulcers. The leaves of the plant were collected from Tarai regions of Himalaya. About 2 kg dried and powdered sample of the leaves was extracted with 50% aqueous methanol and extract obtained was concentrated under...

Objective: To develop and validate simple, rapid, precise, accurate, and economical UV spectrophotometric and reverse phase high performance liquid chromatographic methods for the estimation of alogliptin benzoate (AGP). Methods: UV spectrophotometric method was performed using UV/Vis double beam spectrophotometer with a spectral bandwidth of 1 nm and 1.0 cm matched quartz cells. The maximum ab...
