We present a DSC and X-ray scattering study investigating the effect of polyhedral oligomeric silsesquioxane (POSS) block crystallinity on self-assembly poly(acryloisobutyl silsesquioxane)-b-poly(ethylene oxide)-b-poly(acryloisobutyl silsesquioxane) (POSS-PEO-POSS) triblock copolymer poly(ethylene oxide)-b- (PEO-POSS) diblock copolymers mixed with lithium bis(trifluoromethanesulfonyl)imide salt...

fish roe contains high level of protein and unsaturated fatty acids, but the roe are susceptible to spoilage and its sensorial and qualitative characteristics decrease during storage. salt and antioxidant used in the production of roe to prevent or retard spoilage. this study examined the sensory factors (color, smell, taste, appearance) of rainbow trout roe using plant extracts, such as garlic...

Fifteen crossbred cattle bulls of about 22-24 months age (mean body weight ranged from 291.0 to 298.1 kg) were randomly divided into 3 groups of 5 animals following randomized block design. Animals in group 1 were fed concentrate mixture containing wheat bran 97%, mineral mixture 2% and salt 1% plus ad libitum chopped green sugarcane tops (SCT) as a roughage source. Animals in group 2 were fed ...

Solubilization of phosphatidylinositol (PtdIns) synthase (CDP-diacylglycerol: myo-inositol 3-phosphatidyltransferase, EC 2.7.8.11) from rat pituitary (GH3) tumours was investigated. PtdIns synthase activity was partially extracted from crude membranes by 3 M-KCl. Prior separation of membranes revealed that a greater proportion of plasma-membrane PtdIns synthase activity was salt-extractable tha...

Well-crystallized Li2NiTiO4 nanoparticles are rapidly synthesized by a molten salt method using a mixture of NaCl and KCl salts. X-ray diffraction pattern and scanning electron microscopic image show that Li2NiTiO4 has a cubic rock salt structure with an average particle size of ca. 50 nm. Conductive carbon-coated Li2NiTiO4 is obtained by a facile ball milling method. As a novel 4 V positive ca...

We review the free energy approach to the kinetics of surfactant adsorption at fluid/fluid interfaces. The formalism is applied to several systems. For non-ionic surfactant solutions the results coincide with previous models while indicating their limits of validity. We study the case of surfactant mixtures, focusing on the relation between the mixture kinetics and the properties of its individ...

The effect of ethanol addition to aqueous semi saturated NaCl solutions on the super saturation was studied. The amount of precipitated salt was found to increase as the percent of added ethanol increased. The rates of formation of precipitate were calculated and found to increase with decrease of the weighted average of the solvents mixture dielectric constant, , but levels out at  ≈ 50. The...

The reaction of 3-aminopropylamide of cholic acid with CS₂ produced a bile acid derivative of dithiocarbamic acid which further formed an ammonium salt with another molecule of 3-aminopropylamide of cholic acid. The cationic 3-ammonium propylamide of cholic acid did not react further with CS₂ and the formed salt was stable in the reaction mixture, even when excess CS₂ was used. When the reactio...

A binary mixture of benzyl-amine and hexa-noic acid has been reacted to form the title salt, C(7)H(10)N(+)·C(6)H(11)O(2) (-). This crystal has a 1:1 stoichiometry of acid- and amine-derived species which contrasts with other related species which can have a number of other integer ratios of acid and amine components. The diffraction data indicate complete transfer of a proton from the acid to t...
