(2003)The formation of inclusion complexes of well-known 1,4-dihydropyridine calcium antagonists, such as nifedipine (NF) and nicardipine (NC), with beta-cyclodextrin (betaCD) was investigated by differential pulse polarography ...
-
(2003)The electrochemical behavior of two representative 2,3-dihydro-7H-dibenzo[de,h]quinolin-7-ones was determined using cyclic voltammetry in DMSO as solvent and rationalized by quantum chemical calculations using ab initio ...
-
(Elsevier S.A., 2003)The title compound corresponds to a molecular product of the hydrothermal reaction of CuCl2, Zn, and BIPY (BIPY=2,2′-bipyridine) in the presence of phosphoric acid. The structure of the neutral complex Cu 4(μ2-Cl)4(BIPY)2 ...

Oxidation and catalytic properties of a binuclear copper(I) complex with a meta-xylyl spacer ligand (2003)The oxidation product of the binuclear copper (I) complex Cu2L(CIO4)2 (L = N,N′-bis-(6-methyl-2-pyridil) (2′-pyridyl)methyl m-xylylidene imine) has been isolated and structurally characterised. In the cupric species, ...
-
(ROYAL SOC CHEMISTRY, 2003)A microwave-assisted solvent extraction (MASE) method for the determination of methabenzthiazuron (MBT) in soil samples by HPLC-DAD ( diode array detection) was evaluated. Spiked soil samples having different physico-chemical ...

(WILEY-V C H VERLAG GMBH, 2003-01)The electrochemical behavior of 2-(5-amino- 1,3,4-oxadiazolyl)-5-nitrofuran (NF359) and its comparison with well known drugs such as nifurtimox (NFX) and nitrofurazone (NFZ) in protic, mixed and aprotic media by cyclic ...
-
(TAYLOR & FRANCIS LTD, 2003-01)The phase characterization of two homologous series of liquid crystalline methacrylic monomers based on omega-hexyl- and omega-butyloxysalicylaldimine groups, with different alkoxy tails, is presented. The liquid crystalline ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2003-01-01)The electron spin resonance (ESR) spectra of free radicals obtained by electrolytic or microsomal reduction of several potential antiprotozoal 1,2,5-oxadiazoles were characterized and analyzed. Ab initio molecular orbital ...
-
(ELSEVIER SCIENCE SA, 2003-01-16)The electrooxidation of primary alcohols with four to eight carbon atoms on black Pt electrodeposits on gold/quartz, and on commercial bright platinum/quartz electrodes in perchloric acid solution, was studied by cyclic ...
-
(ELSEVIER SCI LTD, 2003-02)In this study an attempt is made to combine the beneficial effects of probiotics with fruit and vegetables by applying the vacuum impregnation process. Apple cylinders were impregnated either with commercial apple juice ...
-
(MATERIALS RESEARCH SOCIETY, 2003-02)In this paper, we report the preparation by the sol-gel technique of organic-inorganic hybrid composites containing the biopolymer chitosan incorporated in a siloxane-based inorganic network. The hybrid xerogels were ...
