Sol-gel chemistry is currently applied as one of the most widely used methods for synthesis of nanoparticles. In this method hydrolysis and poly-condensation reactions occur when the gel precursors are mixed with water and catalyst. The further condensation of sol particles into a three-dimensional network produces a gel. There are several paramete...

N-nitrosohydroxylamine derivatives are dubbed as chelating agents. The complexation of bivalent metals with N-benzyl-N-nitrosohydroxylamine (L1) and N-(2F-benzyl)-N-nitrosohydroxylamine (L2) were studied with DFT B3LYP modeling, electronic spectroscopy, and X-Ray diffraction. The 3d-metal cations showed good affinity to N-nitroso-N-hydroxylamine de...

Arsenides of boron group metals at standard conditions typ- ically have only one stable phase – zinc blende. Despite it GaAs nanowires frequently grow in a metastable crystal phase – wurtzite. In this paper we show that elastic stress could be the factor responsible for nanowire growth in the metastable phase.

The growth of whisker nanocrystals (NWs) of semiconductors is the only example of crystallization, when three phases simultaneously participate in equilibrium in a multicomponent system: solid, liquid, and vapor. The substance of each phase near the closed line of the three-phase contact is under the influence of the substance of the other two phas...

An environmentally friendly method is proposed to isolate Co3O4 nanoparticles with high surface activity. Instead of usual organic solvents, three different natural sugars, including glycogen, sucrose, and glucose are used for the first time as templates, and water as a green solvent, is used in all the steps. The crystallite sizes of the samples a...

Eight complex compounds of MnII, FeII, CoII, NiII and CuII with 2,4,6-trihydroxy benzoic acid and 3,4,5-trihydroxybenzoic acid were synthesized in a crystalline form. Nanosized metal oxide particles obtained by thermal decomposition of the complexes were studied by X-ray powder dif raction analysis and electron microscopy.

A facile approach for the synthesis of nanoporous cobalt oxide, anatase, rutile, and mix of rutile-anatase phase through thermal decomposition of organometallic complex compounds of phloroglucinol carboxylic acid were used for the first time in order to remove the organic-harmful compounds from water. The complex compounds and nanoparticles were ch...

A series of novel transition and rare-earth metal complexes of (Z)-4-((1-(benzo[d]thiazol-2-yl)-3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-4-yl)diazenyl)-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one (HL) were isolated and identified by FT IR, EPR, ¹H NMR, and UV-VIS spectroscopy. The crystallographic data for [Cu2Cl3(L)(H2O)]2·1.5H2O·CH2Cl2 were obtained....

Mechanistic for relieving pain by using the statin drug as antiinflammatory had been studied, Determination of duration of action of statin also studied. Forty male albino Swiss mice were used in this study were divided randomly into four group (each group 10 mice) G1, G2, G3, G4 giving (0.71 mg/kg diclofenac, 10mg/kg , 20 mg/kg simvastatin, distil...

Novel heterocyclic derivatives of 1-aryl(hetaryl)-3-methyl-4-azopyrazolone-5 and its metal complexes were synthesized. Their color properties were evaluated spectrophotometrically. The ability to use the synthesized compounds as dispersed yellow-to-red dyes for polyamide fibers was demonstrated.

In the title coordination polymer, [Ba(C5HN2O6)(C2O4)0.5(H2O)2] n , the tenfold coordination of the Ba centre consists of four O atoms from the two 4-nitro-2,5,6-trioxo-1,2,5,6-tetra-hydro-pyridin-3-olate (L) anions, three O atoms of two oxalate anions and three water mol-ecules. The Ba-O bond lengths fall in the range 2.698 (3)-2.978 (3) Å. The L...
