A quantum chemical study on structure of 1,2-bis(diphenylphosphinoyl)ethane and hydroquinone cocrystal
(Elsevier Science BV, 2005)
The cocrystal of 1,2-Bis(diphenylphosphinoyl)ethane (DPPEO) with hydroquinone (HQ) (1: 1) were studied theoretically with MINDO/3, MNDO, PM3 and AM I semi-empirical methods to elucidate its structure. The bond lengths and ...
Biomimetic catalysis of an organophosphate by molecularly surface imprinted polymers
(Elsevier Science BV, 2005)
A synthetic polymer selective for paraoxon was prepared by a molecular surface imprinting technique. We have combined molecular imprinting with the ability of histidine to chelate metal ions to create active centrum of ...
Iron removal from human plasma based on molecular recognition using imprinted beads
(Elsevier Science BV, 2005)
The aim of this study is to prepare ion-imprinted polymers which can be used for the selective removal of Fe3+ ions from Fe3+-overdosed human plasma. N-Methacryloly-(L)-glutamic acid (MAGA) was chosen as the complexing ...
Adsorption of Acid Red 57 from aqueous solutions onto surfactant-modified sepiolite
(Elsevier Science BV, 2005)
The adsorption of Acid Red 57 (AR57) onto surfactant-modified sepiolite was investigated in aqueous solution in a batch system with respect to contact time, pH and temperature. The surface modification of surfactant-modified ...
Phosphorus-nitrogen compounds: New spiro-cyclic phosphazene derivatives. Structure of 4 ',4 ',6 ',6 '-tetrachloro-3,4-dihydro-3-(3-methylpyridin-2-yl)-spiro-[1,3,2-benzoxazaphosphinine-2,2 '-(2 lambda(5),4 lambda(5),6 lambda(5)-cyclotriphosphazene)]. Part XII
(Elsevier Science BV, 2005)
The condensation reactions of [N-[(2-hydroxyphenylmethyl)amino]-methylpyridines (5-8) with trimer, N3P3Cl6, have been afforded partially substituted novel spiro-cyclic phosphazene derivatives (9-12) (Scheme 1). Compounds ...
Determination of the alloy scattering potential in modulation-doped In 0.53Ga0.47As/In0.52Al0.48As heterojunctions from magnetotransport measurements
(2005)
The results of magnetotransport measurements are used to investigate the scattering mechanisms and hence to determine the alloy disorder scattering potential in modulation-doped In0.53Ga0.47As/In 0.52Al0.48As heterojunction ...
Oxidation of 2,6-di-tert-butylphenol with tert-butylhydroperoxide catalyzed by cobalt(II) phthalocyanine tetrasulfonate in a methanol-water mixture and formation of an unusual product 4,4 '-dihydroxy-3,3 ',5,5 '-tetra-tert-butylbiphenyl
(Elsevier Science BV, 2005)
The oxidation of 2,6-di-tert-butylphenol (DTBP) with tert-butylhydroperoxide (Bu'OOH) catalyzed by cobalt(II) phthalocyanine tetrasulfonate ([CoPcTS](4-)) in a 4:1 methanol-water mixture gave predominantly the coupled ...
Acidity study on 3-substituted pyridines
(MDPI AG, 2005)
A comprehensive theoretical study for the protonation of some 3-substituted pyridines has been carried out in aqueous solution (epsilon = 78.4) by semi empirical AM1 method in MOPAC2000 and PM5 method in MOPAC2002. Solvent ...
