This paper presents experimental analysis and results of GaN (being a III-V semiconductor) doped with Ferrite elements synthesized using Sol-Gel technique which are carried out at National Chemical Laboratory, Pune Maharashtra. The GaN is employed as dopant for x=1 and x=5, in the formula Ga(2x) N Fe2(49-x) O3 . A non-spinel ferrite system ( Fe2 O3) is chosen for our study. The XRD (Structural)...

Transition-metal centers are the active sites for a broad variety of biological and inorganic chemical reactions. Notwithstanding this central importance, density-functional theory calculations based on generalized-gradient approximations often fail to describe energetics, multiplet structures, reaction barriers, and geometries around the active sites. We suggest here an alternative approach, d...

sulforaphane (sfn) is an isothiocyanate which is produced through glucoraphanin hydrolysis via myrosinase activity. in the present study, sfn content and peroxidase activity has been assessed in treated lepidium draba seedlings with different concentrations of iron and copper during 8 and 16 hours treatment. the results showed that the sfn content drastically elevated at treatment with 1 mg/l f...

The organoindium subhalide [R(Cl)In-In(Cl)R]2 [R = C(SiMe3)3] 1 reacts with Na2[Fe2(CO)8] to form an iron-indium coordination compound which was isolated as the sodium choride adduct [Na(THF)4][Fe2(CO)6(μ-CO)(μ-InR)2Cl] 2. The iron atoms of 2 are bridged by a CO ligand and two InR groups, the indium atoms of which are further connected by the μ2-bridging chlorine atom. Four THF molecules and tw...

We report structurally tuned superconductivity in KxFe2−ySe2−zSz (0 6 z 6 2) phase diagram. Superconducting Tc is suppressed as S is incorporated into the lattice, eventually vanishing at 80% of S. The magnetic and conductivity properties can be related to stoichiometry on poorly occupied Fe1 site and the local environment of nearly fully occupied Fe2 site. The decreasing Tc coincides with the ...

D-(-)-ribose was subjected to oxidation with equimolar amounts of H20 2/Fe2+ and 13-hydroperoxy-9-c/s-l l-fra/75-octadecadienoic acid/Fe2+. Smaller carbohydrates, carbonyl compounds, hydroxy acids and polyols were produced. Identification of carbonyl compounds was achieved by trapping with pentafluorobenzylhydroxylamine hydrochloride (PFBHA-HC1). All products were identified by GC/MS after deri...

Olive mill wastewater (OMW) was exposed to Fenton treatment and subjected to post Fenton coagulation/flocculation using lime. Several tests were performed for different R = H2O2/COD ratios, from 0.25 to 3.0, promoting the gradual addition of H2O2 and Fe2+, with the original condition of a pH = 3.5 and maintaining a constant relationship H2O2/Fe2+ = 15. A maximum reduction of COD of 96.8% was ob...

Antianemic medicament ferrous gluconate, ferrous fumarate, and a Dynabi tablet with a basic iron bearing ingredient were studied with the use of Mössbauer spectroscopy. Room temperature spectra of ferrous gluconate gave clear evidence that the two phases of iron were present: ferrous (Fe2+) as a major one with a contribution at and above 91 a.u.% and ferric (Fe3+) whose contribution was found t...
