Two-dimensional Bi₂Se₃ nanosheets with hexagonal shape are synthesized by a solution synthetic route. The Bi₂Se₃ nanosheets are 120 nm in edge width and 7 nm in thickness. The size of the Bi₂Se₃ nanosheets can be controlled by choosing different kinds of reducing agents including hydroxylamine and ethylenediamine. Subsequently, we demonstrate a configuration of two-color all-optical switching b...

We describe a method for calculating the absorptivity (in terms of substrate consumed) of the colored solution obtained when o-dianisidine dihydrochloride is oxidized by ceruloplasmin. By oxidizing o-dianisidine dihydrochloride with known amounts of hydrogen peroxide we could determine that the molar reacting ratio of o-dianisidine to hydrogen peroxide is 2:1. So calculated, absorptivity is 9.6...

Four chemotherapeutic trials in Iran with the babesicide 3,3-bis(2-imidazoline-2-yl) carbanilide dihydrochloride (Imidocarb dihydrochloride) are reported. Subcutaneous administration at a dose of l mg/kg proved highly effective in controlling experimental infection with a local virulent strain of Babesia bigemina in calves. While treated calves were apparently sterilized of the infection, they ...

A stability indicating High-Performance Liquid Chromatography (HPLC) method was validated and used to study the degradation of cetirizine dihydrochloride in acidic and oxidative conditions. The separation was carried out on a Symmetry C18 column and a mixture of 50 mM KH2PO4 and acetonitrile (60:40 v/v, pH = 3.5) was used as the mobile phase. The method was linear over the range of 1-20 μg/mL o...

S-( +)-Z-hydroxyputrescine.ZHCl and R-( -)-Z-hydroxyputrescine .ZHCl were synthesized from S-( -)and R-( +)hydroxysuccinamide, respectively. Their specific rotations were determined to be [@” = +3.21 f 0.06” and -3.3” (c = SC/c, H20), respectively. The naturally occurring polyamine isolated from Pseudomonas (Kim) appears to be S-2-hydroxyputrescine since the specific rotation of its dihydrochlo...
