Cleansers for the human skin are characterized by their delipidizing, dehydrating and protein-influencing effects. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
Crystallization behavior of synthetic cis-1, 4 polyisoprene (IR), mixed with 0.4×10-2mol/kg_??_4.8×10-2mol/kg saturated fatty acid, was investigated by dilatometry at -25 and -15°C. The crystallization of IR was abruptly promoted by the addition of saturated fatty acids higher than 1.0×10-2mol/kg, such as stearic acid…
Effects of alloying of Al and Si on anodic polarization of Fe-10Cr alloys have been studied in order to assess the possibility of obtaining a lower Cr content stainless steel. Experimental mesurements have been made on anodic polarization curves in 0.05-1.0 kmol·m−3 H2SO4 aqueous solution, pitting potentials in 3.5%Na…
Some series of novel nematic liquid crystalline tolans having high birefringence and low viscosity with a high NA (Nematic-to-Isotropic) transition temperature were developed in order to improve the response time of Supertwisted Nematic-Liquid Crystal Display (STN-LCD). Some nematic liquid crystalline mixtures of the…
Based on a solute atoms diffusion model, contribution from soluble nitrogen to the high-temperature strength was numerically examined for ferritic heat-resisting Fe-Cr-N and Fe-Mo-N alloys. The solute distribution around a moving dislocation was determined by simulating the jump process of interstitial and substitutio…
Constant-compression speed testing was performed using a 99.999 mass% aluminum polycrystal with a grain size of 1.0 mm at temperatures ranging from 413 to 653 K and initial strain rates ranging from 1.67×10−1 s−1 to 1.67×10−5 s−1. The true stress-true strain curves showed a variation from a single peak type to multipe…
The effects of silicon addition on microstructures and tensile properties for Ti-6Al-4V alloy casting were investigated. And the possibility of microstructure control for Ti-6Al-4V-Si alloys by hot-working was discussed. Fine blocky Ti5Si3 intermetallic compounds were precipitated during solidification and cooling at…
The phonon dispersion relations in a CsH 2 PO 4 crystal in a paraelectric phase by means of a rigid molecular-ion model are calculated. The phonon spectra in the quasi-harmonic approximation at various values of temperature and hydrostatic pressure are obtained. The condensation of A u external phonon branch in the ce…
Resumen es: La via de disolucion electroquimica directa se ha utilizado para la preparacion de complejos de ftalocianina y cuatro lantanidos (lantano, neodimio, pr...
The gas-phase catalytic oxidation of benzyl alcohol was carried out over low [CeL, ∽1×10-2 mmol (g-NaZSM-5)-1] and high [CeH, ∽1–2 mmol (g-NaZSM-5)-1] Ce supported NaZSM-5 zeolites and alkali metal added counterparts. The Ce was supported on NaZSM-5 zeolites by both ion-exchange (CeL-NaZSM-5) and impregnation (CeL- an…
Mechanical alloying (MA) of elemental powder mixtures, with an Fe-9.85 mass%N alloy powder as the nitrogen source, of the composition of Cr–Mn type stainless steels was carried out in an Ar atmosphere using a conventional planetary ball mill. In the MA processing of Fe79−x−yCr18MnyMo3Nx (mass%) (x=0.45 and 0.9; y=5–18…
A spin cast film of poly(hexamethylene adipamide) (Nylon 6,6) was analyzed by XPS using monochromatic Al Kα excitation. The measured atomic composition closely matched the expected stoichiometry of the polymer. Peak positions of the individual chemically shifted C 1s, O 1s, and N 1s components are reported. The result…
When studying the structural properties of highly entropic materials, the usual criteria for the choice of the time step, the stability of the energy and the pressure, are not always appropriate as they may lead to a time step which is an order of magnitude too large. Two different methods, the stress-strain and equil…
Chitosan is poly-β(l→4)-2-amino-2-deoxy-β-D-glucan (Figure 13.1), deacetylated chitin. Chitin is widely found in crustacean shells, fungi, insects, annelids, mollusks, coelenterates, etc. (Muzzarelli 1990). Chitosan is produced commercially from chitin, the major component of crustacean shells, most often from shrimp-…
We investigated the frequency characteristics of permeability for an Fe-Si-Al flakes/polymer composite which has dual frequency dispersion in permeability. From the relation of Curie temperature to the powder surface area, it was found that the mother alloy composition changes with progress of attrition to excess Fe,…
The aim of this article is to provide a comprehensive review of specific problems and deficits in the monitoring and dosimetry of thorium intakes. Thus, the known monitoring methods are critically discussed in respect of their detection selectivity for realistic intakes of 232 Th and their detection sensitivity in gen…
We performed high-field magnetization measurements for the aligned powder of a high-quality Sm2Fe17N3.1 at 4.2 K up to 23 T. The result indicates a strong anisotropic behavior in the magnetization curves along the parallel and perpendicular directions to the aligned one. From the hard axis-magnetization curve, the uni…
Neutron diffraction, magnetic susceptibility and EPR spectroscopic studies of a dodecanuclear chromium cage are reported which show the molecule has an S = 6 spin ground state; this is the highest spin ground state known for a cage of this metal.
We shall review some results from several areas of oxide science in which neutron scattering and X-ray synchrotron scattering exercise a complementary role to high-resolution transmission electron microscopy. The very high-resolution time-of-flight neutron diffraction technique and its role in studies of the magnetic…
This paper presents research characterizing the leakage (incipient behaviour) of single and multiple distribution insulators through staged experiments. Four sets of field experiments were conducted over a two year period in which single and multiple insulators were artificially contaminated and energized on a lateral…
