In this study, hierarchical H-ZSM-5 zeolite is prepared via post-synthetic modification of parent H-ZSM-5 zeolite (Si/Al=35) synthesized from bagasse (BGA) as silica source using desilication with alkaline treatment (AT). For optimizing the effective parameters on desilication, Taguchi method was utilized. Cultivated BGA in the south of the Caspian Sea (Mazandaran province, Iran) is applied for...

In the article, in order to evaluate effect of various factors on oxidation process n-butane, a series experiments were conducted at temperature 170 ℃ for 58 hours with mixing reactants reactor speed 0.05 m amplitude 2s-1. Infrared spectroscopy, transmission electron microscopy, and powder X-ray diffraction data reported. According infrared when ratio tetra-Npropylammonium hydroxide/tetraethoxy...

mg(oh)2 nanoparticles were synthesized by a rapid microwave reaction. the effect of sodium dodecyl sulfonate (sds as anionic surfactant) and cetyl tri-methyl ammonium bromide (ctab as cationic surfactant) on the morphology of magnesium hydroxide nanostructures was investigated. multi wall carbon nano tubes was organo-modified for better dispersion in cellulose acetate matrix. the influence of m...

Modafinil (Diphenyl methyl Sulfinyl acetamid) is used clinically in the treatment of narcolepsy and sleeping disorders. The synthesis of R-modafinil, have started with the reaction of benzhydrol and thioglycolic acid in trifluoroacetic acid to afford benzhydryl sulfanyl acetic acid. The reaction of acid with thionyl chloride in benzene followed by treatment with ammonium hydroxide gave acetamid...

A debris-free, narrow-bandwidth, single-line laser-plasma soft x-ray source has been developed suitable for water-window microscopy using zone-plate optics. The 10 Hz table-top source utilizes microscopic ammonium hydroxide droplets as target. The N VI emission at l52.88 nm is ;1310 photons/~sr pulse!. As an alternative to ammonium hydroxide, it is demonstrated that urea dissolved in water also...

The title compound, penta-caesium nona-stannide hydroxide tetra-ammonia, crystallized from a solution of CsSnBi in liquid ammonia. The Sn9 (4-) unit forms a monocapped quadratic anti-prism. The hydroxide ion is surrounded by five caesium cations, which form a distorted quadratic pyramidal polyhedron. A three-dimensional network is formed by Cs-Sn [3.8881 (7) Å to 4.5284 (7) Å] and Cs-NH3 [3.276...
