Understanding the mechanism of catalytic upgrade bio-oils via process hydrodeoxygenation (HDO) is desirable to produce targeted oxygen-deficient bio-fuels. We have used calculations based on density functional theory investigate reaction HDO guaiacol over Cu (111) surface in presence H2, leading formation catechol and anisole. Our analysis thermodynamics kinetics involved shows that produced di...
the effect of ascorbic acid (aa) and butylated hydroxyanisole (bha) supplementation on aflatoxicosis in broiler chickens (1 to 42 days of age) was investigated (250, 500, 1000 and 2000 ppm for aa and bha) in diet containing 1 ppm total aflatoxin (af: 76.45% afb1, 10.52% afb2, 9.89% afg1 and 3.14% afg2). a total of 300 day-old broiler chicks were divided into ten treatment groups (t1=control; t2...
The rotational spectra of anisole and of benzaldehyde were investigated in supersonic expansion at frequencies up to 41 GHz, and at room temperature in the millimetre-wave region, from 170 to 330 GHz. Accurate spectroscopic constants for the parent isotopomers in the ground vibrational state and for the first excited torsional state were determined for both molecules. The supersonic expansion s...
Sulfonic acid-incorporated-MCM-41 mesoporous materials prepared using a silane containing tetrasulfide linkages showed exceptional yields of the acetylated product in the acetylation of anisole due to their high content of strong acid sites.
Free radicals and reactive oxygen species (ROS) are the cause of diseases such as cancer, diabetes, cardiovascular inflammatory. The presence an increase in number free excess ROS production body can imbalance immune system. Therefore, additional antioxidants needed from outside body. During this time there several antioxidant synthesis drugs (Butyl Hydroxy Anisole) BHA Hydroxyl Toluene) BHT. B...
In the present study, tin nanoparticles were green-synthesized using aqueous extract of Foeniculum vulgare leaf extract. The synthesized SnNPs (tin nanoparticles) characterized by analytical techniques including EDX (energy dispersive X-ray), FE-SEM (field emission scanning electron microscopy), XRD (X-ray diffraction), UV–vis and FT-IR (Fourier transform-infrared). cytotoxicity activity was ev...
One- and two-photon absorption cross-sections and spectra and the photophysical properties of eight perylenetetracarboxy-3,4:9,10-diimide (PDI) derivatives are reported and analyzed. The investigated compounds are characterized by direct binding of the phenyl rings of the substituents to the bay positions of the perylene core. They have been designed to test the effects of differences in the el...
Lichens are considered a great bio-resource because they produce large numbers of secondary metabolites with many biological activities; however, they have not been cultivated under artificial conditions to date. As a result, lichen substances from natural sources are limited and have not been widely utilized in commercial applications. Accordingly, interest in lichen-associated fungi, especial...
A simple and reliable electrochemical sensor based on cobalt oxide nanoparticles modified glassy carbon electrode (GCE/CoOxNPs) for determination of butylated hydroxyanisole is presented here. The nanoparticles were fabricated by electrodepositing method. The modified electrode shows excellent catalytic activity toward butylated hydroxyanisole oxidation in pH 12.0 phosphate buffer solution (PBS...
