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...

Inducing high levels of reactive oxygen species (ROS) inside tumor cells is a cancer therapy method termed chemodynamic (CDT). Relying on delivery Fenton reaction promoters such as Fe2+, CDT takes advantage overproduced ROS in the microenvironment. We developed peptide-H2S donor conjugate, complexed with AAN-PTC–Fe2+. The AAN tripeptide was specifically cleaved by legumain, an enzyme overexpres...

The present experiment addressed the effects of different iron (Fe) concentrations in nutrient solution supplied as Fe-HBED, i.e., 0.02 (Fe0, control), 1.02 (Fe1), and 2.02 mmol L−1 (Fe2) on lettuce (‘Nauplus’ ‘Romana’) yield compositional traits. This was carried out a greenhouse using an open soilless cultivation system, at experimental farm University Catania (Sicily, Italy: 37°24′31.5″ N, 1...

Salah satu pencemar yang berbahaya dalam limbah buangan industri yaitu logam berat besi (Fe2+). Banyak teknik pengolahan dilakukan untuk mwnurunkan kadar besi. satunya diantaranya adalah dengan adsorbs. Adsorpsi sering digunakan karena prosesnya sederhana dan efektif mengurangi berat. Penelitian ini bertujuan menganalisis efektifitas karbon aktif kulit singkong sebagai adsorben pada penyerapan ...
