Molecular mechanics study of nickel(II) octaethylporphyrin adsorbed on graphite(0001)
(MDPI, 2007)
The effects of adsorption on the graphite(0001) surface on the nonplanar distortions of nickel(II) octaethylporphyrin were studied by molecular mechanics (MM) approach. Using the Consistent Force Field (CFF) program with ...
pH-Dependent Leaching of Dump Coal Ash-Retrospective Environmental Analysis
(Taylor & Francis Inc, Philadelphia, 2009)
Trace and major elements in coal ash particles from dump of "Nikola Tesla A" power plant in Obrenovac near Belgrade (Serbia) can cause pollution, due to leaching by atmospheric and surface waters. In order to assess this ...
Iron catalyzed conversion of NO into nitrosonium (NO+) and nitroxyl (HNO/NO-) species
(Elsevier, 2004)
The conversion of NO into its congeners, nitrosonium (NO+) and nitroxyl (HNO/NO-) species, has important consequences in NO metabolism. Dinitrosyl iron complex (DNIC) combined with thiol ligands was shown to catalyze the ...
Identification of secretory compounds from the European callipodidan species Apfelbeckia insculpta
(Springer, Dordrecht, 2009)
Defensive secretions of the callipodidan species Apfelbeckia insculpta contain a p-cresol as the main component and phenol in traces. This is the first identification of these compounds in a European callipodidan species. ...
The kinetics of ethanol adsorption from the aqueous phase onto zeolite NaZSM-5
(Springer, New York, 2008)
The kinetics of the isothermal adsorption of ethanol from an aqueous solution onto a hydrophobic zeolite of the NaZSM-5 type in the temperature range 298-333 K was investigated. Specific shape parameters of the adsorption ...
X-ray analyses, spectroscopic and magnetic properties of [Cu4(succinato)(tpmc)2](ClO4) 6·2C2H5OH·4H2O and [Cu2(C6H5COO)tpmc](ClO4) 3·0.5CH3OH·0.5H2O complexes
(Elsevier, 2008)
[Cu4(succinato)(tpmc)2](ClO4) 6 · 2H2O (tpmc = N,N′,N″,N‴-tetrakis-(2-pyridylmethyl)-1,4,8,11-tetraa zacyclotetradecane, succinato = dianion of succinic acid) has been prepared and characterized by elemental analysis, ...
Purification and properties of midgut α-amylase isolated from Morimus funereus (Coleoptera: Cerambycidae) larvae
(Elsevier Science Inc, New York, 2008)
Using soluble starch as a substrate five isoforms of α-amylase were identified in a crude extract of Morimus funereus larvae. The main α-amylase (termed AMF-3) was purified by gel filtration chromatography and anion exchange ...
High-yield synthesis of substituted and unsubstituted pyridinium salts containing a 4-oxothiazolidine moiety
(Georg Thieme Verlag Kg, Stuttgart, 2008)
A new series of unsubstituted and substituted pyridinium salts bearing a 4-oxothiazolidinyl moiety has been prepared by an efficient rearrangement of 2-(l-bromoalkylidene)thiazolidin-4-ones. The process is based on three ...
Oxidation of n-hexane over Pt and Cu-Co oxide catalysts supported on a thin-film zirconia/stainless steel carrier
(Catalysis Communications, 2008)
The complete oxidation of n-hexane in air over a stainless steel foil (SS) coated with a thin film of ZrO2 (SS/ZrO2), SS/ZrO2/Pt, SS/ZrO2/La2O3/CuCo and SS/ZrO2/La2O3/CuCo/Pt catalysts has been investigated. The ZrO2 films ...
Toluene Degradation in Water Using AlFe-Pillared Clay Catalysts
(Science Press, Beijing, 2009)
The catalytic wet peroxide oxidation (CWPO) of toluene on two bentonite-based AlFe-pillared clays (PILCs) with different iron contents was investigated. The PILCs were obtained using bentonite clay from Bogovina, Serbia. ...
