Stannous oxide (SnO) and stannic oxide (SnO2) are both important wide-band-gap semiconductors. To study the conductive mechanism in detail, high quality epitaxial films are essential. Here we propose a simple method to grow high quality epitaxial films of either stannous oxide or stannic oxide o...

Tungsten doped stannic oxide transparent conductive thin films (W-doped SnO2) have been prepared via a solution process. We use stannous chloride, preoxotungstic acid (PTA), hydrogen peroxide and anhydrous ethanol to prepare precursor solution which is stable and colorless. By investigating the ...

A simple hydrothermal process is proposed for preparing stannic oxide nano-hexagons. Structural, morphological and phase information were determined by high resolution X-Ray diffraction (HR-XRD) and high resolution transmission electron microscope (HR-TEM) techniques. Optical properties and band...

High-acid squid visceral oil is unsuitable for consumption owing to its high content of free fatty acids (FAs). In this study, an edible grade resource of n-3 polyunsaturated fatty acids (PUFA) was developed from high-acid squid visceral oil (HASVO) by converting free FAs and partial glycerides ...

ObjectiveTo evaluate fatty acid composition and the antimicrobial activity of the major fraction of fatty acid methyl ester (FAME) extracts from three microalgae collected from freshwater lakes in Theni District, Tamil Nadu, India.

This work reports a new set of experimental data for the liquid–liquid equilibrium for {soybean oil + soybean oil ethyl esters + (ethanol + water)} systems at atmospheric pressure and at T = (298.15, 313.15 and 323.15) K, while pseudobinary solubility data were obtained for the system {soybean ...

Tricosanoic acid (23:0) and cis-15-tetracosenoic acid (nervonic acid, 24:1n—9) were compared as choices suitable for use as internal standards in the quantitation of eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids. Experiments conducted included: (a) comparison of the flame ionisat...

The purpose of this paper was to develop and validate a simple adapted method for the quality control of the determination of total esters, mono-, di-, and triacylglycerides and free and total glycerol content in methyl or ethyl biodiesel. Advantages of the method over the standard EN 14103 and ...

This study explores dog plasma and brain fatty acid composition achieved after long-term supplementation at high DHA doses. A 90% concentrate of DHA Ethyl Ester (DHA-EE) administered by oral gavage to Beagle dogs at doses of 100, 500, 1000, and 2000 mg/kg bw/day for 8 weeks resulted in DHA incre...

Microbial production of fatty acid derived chemicals and fuels is currently of great interest due to the limited resources and increasing prices of petroleum and petroleum-based products. The development of Saccharomyces cerevisiae as a fatty acid ethyl ester (FAEE) cell factory would represent ...

The present study deals with the grafting of barley husk (BH) with lauric acid, palmitic acid and arachidic acid in the presence of redox initiators. The grafting reaction parameters (reaction time, reaction temperature, dimethyl sulphoxide (DMSO) content, fatty acid concentration) were optimize...

Chitosan oligosaccharide–arachidic acid (CSOAA) conjugate was successfully synthesized and used for the development of self-assembled nanoparticles for doxorubicin (DOX) delivery. The molar substitution of AA on CSO and critical micelle concentration (CMC) of CSOAA were measured. Physicochemica...

In this study, the ultrasound-assisted extraction (UAE) of radish seed oil (RSO) using ethanol as the solvent was investigated with the aim of ester synthesis by in situ reaction. An experimental design was used to evaluate the effects of temperature, solvent to seed ratio and time on the effici...

Hydrolysis of acid oils is an important alternative for the production of non-ionic surfactants and fatty acids that can be converted to fatty acid methyl esters (biodiesel) by esterification. In this work, hydrolysis of palm oil was initially carried out in subcritical water using zinc stearate...

The transesterification of the lipid fraction of grease trap waste in a catalyst-free medium, under supercritical conditions, was studied. The aim was to evaluate the effect of different concentrations of water (in ethanol) on the production of ethyl esters. Reactions were conducted in a continu...

Increased rate of use of fossil fuels have greatly polluted the earth through harmful by-products. Biodiesel is an attractive substitute to fossil fuel in compression ignition engine applications. In this research work, vegetable oil namely Arachis Hypogaea Oil (AHO) is used along with ethanol f...

Herein, we improve the procedure for organic rice authentication using compound-specific δ13C and δ15N analyses of fatty acids and amino acids, addressing the increasing demand for accurate methods to confirm organic authenticity. Organic rice (OR) and pesticide-free rice (PFR) featured higher...

The extraction/enrichment of omega − 3 polyunsaturated fatty acid methyl esters (PUFAMEs) by hydrophobic ionic liquids (ILs) containing silver salts as the extraction phase has been extended to include equilibrium studies. The extraction time, organic solvents, IL structures, and AgBF4 concentra...

The characterisation of the isolated natural product from soybean oil deodoriser distillate (SODD) has gained increasing importance due to health concerns.
