Three surfactants were selected to modify glassy carbon electrode including sodiumdodecylbenzenesulfonate, Tween 80 and cetyltrimethylammonium bromide. The obtained nano-Au/surfactant/GCEs were characterized with scanning electron microscopy and electrochemicaltechniques. Electrochemical behavior of catechol at the nano-Au/surfactant/GCE was thoroughlyinvestigated for mo...

This article reports a novel synthetic methodology for preparing Bi2Te3 nanotubes as well tailoring their size and aspect ratio, which provides strong potential interest in the field of thermoelectrics. were synthesized via 1-dodecanethiol (DDT) assisted aqueous two-steps synthesis. One its main advantages is to be easily scalable because it carried under mild experimental conditions. The compl...

The UV-persulfate oxidation method is widely used for determining the total organic carbon concentration of aqueous samples (denoted convenience as UVP-TOC). However, some surface water samples, measurement TOC by this can be unreliable, deviating significantly from true content. In study, performance UVP-TOC has been investigated comparing results analysis a variety that included two kinds and...

Anionic DBS surfactant can be photodegraded in a TiO2 dispersion and H2O2 solution under an Hg-lamp (15 W) UV illumination or solar exposure. Degradation process has been monitored through cleavage of aromatic moiety. Degradation of the detergent was small when the photolysis was carried out in the absence of TiO2 and H2O2 an...

Rice starch is used as an additive in various food and industrial products. With the inherent merits of small and uniform size distribution of rice starch and its white color and clean odor, deserts and bakery products are some of the favorable applications among processed foods [1]. The small granular size of the starch imparts it soft texture, high water retention and low syneresis, suggestin...

Several methods (e.g., UV/H2O2 oxidation, adsorption, flocculation-precipitation) are normally employed to remove dye from water. A new technique based on liquid/liquid extraction using reverse micelles is proposed whereby recovery of solvent and reuse of dye is possible. Experiments were conducted by mixing a known quantity of dye in aqueous phase and solvent-containing surfactants in a simple...

Several high voltage condenser type OIP (oil impregnated paper) bushings used in the electrical industry are filled with dodecylbenzene, because of its ability to absorb hydrogen formed by corona partial discharges thick paper insulation these pieces equipment. Some them form large quantities ethane, raising concern overheating faults their insulation, which may be risky for safe operation serv...

In this study, linear alkyl-benzene calcium sulfonate nanoparticles were made using linear alkylbenzene. Calcium sulfonate nanoparticles are widely used as an additive in a variety of engine oils and have cleansing, anti-wear and anti-oxidant properties and anti-corrosion properties. In this method, a sulfonation set up was constructed and sulfonation reaction was carried out both directly and ...

Positive ion mode collision-activated dissociation tandem mass spectrometry (CAD MS/MS) of O-sulfopeptides precludes determination of sulfonated sites due to facile proton-driven loss of the highly labile sulfonate groups. A previously proposed method for localizing peptide and protein O-sulfonation involves derivatization of nonsulfonated tyrosines followed by positive ion CAD MS/MS of the cor...
