The wheat straw as abundant lignocellulosic resource was successfully undergone in a benzylation reaction and plasticized with different contents (2.5, 3, 5 and 7 wt. %) of glycerol and stearic acid.The effect of type and concentration of plasticizers on the mechanical, thermomechanical, morphological and water absorption properties of Benzylated Wheat Straw (BWS) was investigated ...

In this paper we report synthesis of Fe2TiO5-5A zeolite (Z5A) nanocomposites with 5%, 10% and 20% weight percent of Fe2TiO5 in 5A zeolite in stearic acid media after calcination of the gel samples obtained at 600-900°C for 2 hrs. The powder X-RAY diffraction (XRD) patterns have been used for characterization of the prepared samples. The Scanning Electron Microscopy (SEM) images and X-ray Energy...

In order to obtain hydrophobic material, the water suspension of natural limestone with the high content of calcite (>95 %), was treated with different amounts (0.5-4 %) of stearic acid dissolved in chloroform. Thermal analysis showed that at lower initial concentrations of stearic acid (up to 2 %), surfactant molecules are chemisorbed on calcite surface, while at higher initial concentrations ...

Sugar fatty acid esters are practical importance and have a variety of applications that include surfactants and as an emulsifying agent. In this study, we report glucose stearate synthesis using lipase-Fe3O4 nanoparticles catalyst. The influence of various reaction factors, such as silica gel concentration, molar ratio of sugar/acid, reaction temperature and speed of agitation on esterificatio...

TiO2 films prepared by template-assisted sol-gel method were characterized by X-ray diffraction spectroscopy, scanning and atomic force electron microscopy, and Fourier transform infrared (FT-IR) spectroscopy. Based on the hexane adsorption-desorption analysis, the films have a surface area of 390-540 m(2)/g with pore size distribution narrowly centered around 10 nm. Optimal component ratio and...

Stearoyl-acyl carrier protein desaturase (SACPD-C) has been reported to control the accumulation of seed stearic acid; however, no study has previously reported its involvement in leaf stearic acid content and impact on leaf structure and morphology. A subset of an ethyl methanesulfonate mutagenized population of soybean (Glycine max) 'Forrest' was screened to identify mutants within the GmSACP...

A new method is described for the determination of brain gangliosides by measuring stearic acid, the chief acid of gangliosides, in an appropriately purified brain extract. The method includes extraction of tissue with chloroform-methanol, extraction of gangliosides from the extract with 0.1 M KCl, evaporation of the aqueous phase, methanolysis, and gas-liquid chromatography of the resultant me...

Superhydrophobic surfaces were prepared using a two-step method that involved the etching of AZ31 and AZ91 magnesium alloys then modifying etched with stearic acid. Magnesium ZnCl2 SnCl2 exhibited roughened micro- nanoscale hierarchical structures consisting two chemically distinct regions (Zn/Zn(OH)2 or Sn/SnO2 Mg(OH)2). An optimum time ten minutes was chosen for both etchants. highest contact...
