the kinetic study of the condensation reaction between phloroglucinol and acetone was investigated at 30, 35, 40 and 45±0.05 °c in 100% methanol. the hydrochloric acid concentrations used were 0.0261, 0.0364, 0.0577 and 0.0728 m. the reaction was investigated with and without a promoter, thioglycollic acid (tga), and taking into account the functionality (h) of phloroglucionol. the reaction was...

A series of In2O3/Au nanorods (NRs) were fabricated and characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffractometer (XRD) and X-ray photoelectron spectroscopy (XPS). The length to diameter ratios of In2O3/Au NRs was periodically modulated in the range of 2.9-4.5 through controlling the initial content of indium salt and reaction time. Their ...

In this study, it was aimed to compare the antioxidant properties of extracts obtained from extraction olive leaves in Hatay province prepared with different solvents. For purpose, were extracted using pure methyl alcohol soxhlet and also by maceration 60% ethanol, 70% methanol, 90% acetone (v/v) distilled water. Total Flavonoid Content (TFC), Phenolic (TPC), Ferric Antioxidant Reducing Power (...

Measurement of a volatile solution is essential for laboratory safety and hospital clinic safety. In this paper, we present an ethanol-sensing acetone-sensing device using AlN piezoelectric material-based film bulk acoustic resonator (FBAR). order to realize sensing, the AlN-based FBAR was designed, fabricated, characterized. our sensor structure, upper electrode Ti/Au (30 nm/150 nm) composite ...

With global carbon emissions and environmental issues becoming increasingly prominent, there is an increasing focus on the development of clean energy, biobutanol has gained widespread attention due to its superior performance. Butanol production by fermentation affected various factors, such as raw materials, cultivation environment, butanol toxicity, which results in lower restricts industria...

The present study was conducted to evaluate the hepatoprotective effects of aqueous acetone extract of Sida alba. (Malvaceae) an herbal plant used in Burkina Faso to treat traditionally hepatics affections in albinos Wistar rats. Animals were treated by gavage during 28 days with different doses of aqueous acetone extracts of Sida alba. (75, 100, 150 mg/kg) suspended in 35% ethanol. Control gro...

A total of 115 different plant extracts from our collection, representing 96 plant species, have been evaluated for in vitro antileishmanial activity against L. amazonensis promastigotes. In addition, the extracts were screened for cytotoxic activity against BALB/c mouse macrophages in order to assess a selectivity index. Crude extracts that showed a selectivity index (CC50 for macrophage / IC5...

OBJECTIVE To evaluate in vitro antibacterial effectiveness of five medicinal plants used by an Indian aborigine, against 8 multidrug-resistant (MDR) enteropathogenic bacteria isolated from clinical samples of under-5 hospitalized children. METHODS Antibiotic sensitivity patterns of eight clinically isolated strains of enteropathogenic bacteria, Enterobacter aerogenes, Escherichia coli, Klebsi...

The use of solid dispersion techniques to modify physicochemical properties and improve solubility and dissolution rate may result in alteration to electrostatic properties of particles. Particle triboelectrification plays an important part in powder processing, affecting end product quality due to particle deposition and powder loss. This study investigates the use of glucosamine hydrochloride...

Abstract Graphene oxide (GO) thin films were prepared successfully using modified Hummer’s method, which includes oxidation of graphite and reduction to graphene at room temperature. Then; the samples deposited on glass substrates sol-gel technique. Different solutions have been used obtain such as Ethanol, Acetone, Deionized Water. The structural, optical electrical properties diagnosed studie...
