This paper presents a simple and effective oil-water interfacial self-assembly strategy to fabricate monolayer and bilayer nanofilms of densely packed Gd2O3:0.05X(3+) (X = Eu, Tb) nanorods with characteristic luminescence properties. In this process, Gd2O3:0.05X(3+) (X = Eu, Tb) nanotubes synthesized by a hydrothermal method are dispersed in deionized water; then, a certain amount of n-hexane i...

The strain MA428-C1 was shaken-cultured (120 strokes/min., 8 cm amplitude) in. a medium (pH7.0) containing 2% glucose, 1.5% soybean meal, 0.3% NaCl, 0.1% K2HPO4, 0.1 % MgSO4-7H2O, 0.0007 % CuSO4-5H2O, 0.0001 % FeSO4-7H2O, 0.0008 % MnCl2-4H2O, 0.0002% ZnSO4-7H2O at 27°C for 5 days. The amount of gougeroxymycin was determined by a cylinder plate method described by one of the authors1}.. About 70...

Abstract Cnidium officinalis rhizomes were immersed in 80% MeOH. The extract was fractionated to water, n -butanol, and ethyl acetate fractions (Fr). Open column chromatography repeatedly carried out on n-butanol Fr using silica gel, octadecyl Sephadex LH-20 as the stationary phase affording five phenyl alkanoids 1 – 5 including two new ones. molecular structures stereochemistry decided based s...

Benign Prostatic Hyperplasia (BPH) affects, worldwide, 50% of 60-year-old men. The Peruvian plant red maca (Lepidium meyenii) inhibits BPH in rodents. This study aimed to determine the effects of methanolic red maca extract and its n-butanol and aqueous fractions on expression of androgen and oestrogen receptors in rats with testosterone enanthate-induced BPH. Thirty-six rats in six groups were...

Pentanol is one of the promising "next generation" alcohol fuels with high energy density and low hygroscopicity. In the present work, dominant reaction channels of thermal decomposition of three isomers of pentanol: 1-pentanol, 2-methyl-1-butanol, and 3-methyl-1-butanol were investigated by CBS-QB3 calculations. Subsequently, the temperature- and pressure-dependent rate constants for these cha...

A new tert-butanol solvate of [{((i)PrC(6)H(4)Me)RuCl}(2){μ-2,5-pyz(COO)(2)}] (pyz = pyrazine) has been crystallized and structurally characterized. The solvate, [Ru(2)(C(10)H(14))(2)(C(6)H(2)N(2)O(4))Cl(2)]·2C(4)H(10)O, contains one half-mol-ecule of the ruthenium(II) complex and one mol-ecule of tert-butanol in the asymmetric unit. The complex mol-ecule lies on an inversion centre with the tw...

Background: The leaf extract of Croton zambesicus (CZ) is used in traditional medicine for the management of various conditions including kidney disease. The purpose of this study was to determine the protective effects of leaf extract of CZ on rat kidney toxicity induced by carbon tetrachloride. Method: Male albino rats were divided into 6 groups of 5 rats and treated for 5 days with aqueous ...

This paper reports experimental work pertaining to alcoholysis between butanol and ethyl butanoate, catalyzed by an immobilized lipase in a liquid-vapor system where chemical reaction and physical separation are simultaneously carried out. The processing setup was tested for various compositions of the starting feedstock and operated under reduced pressure. Samples were withdrawn both from the ...
