Resumen
Sodium stearate modified montmorillonite(SSTA-MMT) is prepared by using the anion surfactant sodium stearate, and its structure is characterized by X-ray and FI-IR diffraction. The results show that sodium stearate can be intercalated into the interlayers of montmorillonite and the layer spacing is expanded from 12.74 to 48.05 Å with the loading concentration of sodium stearate increasing from 5 % to 100 % CEC of Na-MMT. The adsorption of methylene blue onto SSTA-MMT experiments show that the adsorption kinetic of methylene blue onto SSTA-MMT can be best described by the pseudo-second-order mo

Introduction. Given the significant prevalence of lead in the environment, research in this area has significant social and economic importance. Lead compounds are characterized by high toxicity and increased ability to cumulate in ecosystems, humans, and animals.

Resumen
Compatibility investigation was performed between stearate lubricants (sodium stearate and magnesium stearate) and acidic pharmaceutical compounds (ibuprofen, indomethacin and valproic acid) and citric acid as acidic pharmaceutical excipient using differential scanning calorimetry (DSC). Alteration in DSC thermogram was found in all mixtures. There was a presence of melting endothermic peak of stearic acid in all mixtures (except that of stearate lubricants and indomethacin) indicating breakage of salt form of stearate lubricants depended on the physicochemical properties of drug compounds and

Resumen
Iron oxide nanoparticles are widely used as a contrast agent in magnetic resonance imaging (MRI), and may be used as therapeutic agent for magnetic hyperthermia if they display in particular high magnetic anisotropy. Considering the effect of nanoparticles shape on anisotropy, a reproducible shape control of nanoparticles is a current synthesis challenge. By investigating reaction parameters, such as the iron precursor structure, its water content, but also the amount of the surfactant (sodium oleate) reported to control the shape, iron oxide nanoparticles with different shape and composition

Resumen
Considering the fact of low gloss and masking power of aluminum powder, the aluminum powder is chemically modified by wet covering with eight kinds of single surfactants such as Oleic acid, Stearic acid, Sodium dodecyl sulfonate, Sodium stearate, Polyvinyl alcohol, Polyethylene glycol, Tween-80 and Emulsifier-OP in different proportions on the surface of aluminum powder and the gloss of aluminum paste printing ink concocted with the covered aluminum powder is tested. The results show that the gloss of the aluminum powder covered by one percent Polyvinyl alcohol increases most significant. In o

Resumen
Four commercial emulsifiers, sodium oleate, sodium stearate, sodium stearoyl-2-lactylate, and calcium stearoyl-2-lactylate, were evaluated for their effectiveness as inhibitors of Pseudomonas lipases. Each emulsifier was incubated at 0.5, 1.0, and 2.0% concentrations with the individual as well as a mixture of the crude lipase extracts obtained from three Pseudomonas spp. (P. fluorescens, P. putida, and P. cepacia), in reconstituted nonfat dry milk (10%) for 30 min. At a 2% concentration, all emulsifiers tested were potent inhibitors (100%) of lipase activity. The effectiveness of lipolysis in

Resumen
Nowadays, polypropylene-based nonwovens are used in many areas, from filtration to medicine. One of the methods for obtaining such materials is melt electrospinning. In some cases, it is especially interesting to produce composite fibers with a high degree of filling. In this work, the influence of the filling degree of isotactic polypropylene with calcium carbonate on the structure and properties of nonwoven materials obtained by melt electrospinning was studied. It was shown that electrospinning is possible, even at a filler content of 50%, while the average diameter of the fibers increases

Resumen
High-quality point clouds are the bases of high-accuracy three-dimensional (3D) model. How to obtain the corresponding surface point clouds is always an important work in reverse engineering. Faro Laser Scanner Fonton120 was used to scan an organic material which is composed of potassium stearate, sodium stearate, polyvinyl alcohol and paraffin liquid in a dark room. The organic material has fewer reflectors and is penetrated by laser of scanner. For increasing the reflector and obtaining high-accuracy 3D model, the flash sliver was coated on organic material’s surface. Flash sliver was found

Resumen
The molten alkali was investigated on the pyrolysis of fatty acid sodium salts; furthermore, the difference of pyrolysate between saturate and un-saturate fatty acid sodium salts was also given. In the presence of molten alkali, the pyrolysis of saturated sodium stearate leaded to high content of alkanes (nearly 60%) and low content of oxygen-containing compounds (almost 3%). But for the pyrolysis of un-saturated sodium oleate, high amount of aromatics (nearly 24%) and low amount of oxygen-containing compounds (1%) were detected. Compared with the pyrolysis without molten alkali, less oxygen-c

Resumen
AbstractCopper-aluminum layered double hydroxides (Cu-LDHs) and nickel-aluminum layered double hydroxides (Ni-LDHs) were synthesized using co-precipitation method. LDHs were organically modified by long chain sodium stearate. Polypropylene (PP)/layered double hydroxides (LDHs) and polypropylene (PP)/organically-modified layered double hydroxides (m.Cu-LDHs or m.Ni-LDHs) were prepared through the melt bending of the PP with either nanosized LDHs or m.LDHs without any other additives. The effect of stearate on the dispersibility of LDHs was investigated by X-ray diffraction (XRD). The surface mo
