(ELSEVIER SCIENCE SA, 2012)In this paper, we investigated the electrochemical metal-ion sensor activity of a manganese phthalocyanine (MnPc). For this purpose, interactions of MnPc with various transition metal ions were examined in solution and in ...
-
(POLISH ACAD SCIENCES INST PHYSICS, 2012)Sol-gel technique was employed to prepare semiconductor tin dioxide (SnO2) thin films. Comparatively, it gives an advantage over other techniques by its low reaction temperature, easy process and low cost. The effect of ...
-
(SPRINGER, 2012)A BCR-sequential extraction procedure for the determination of extractable heavy metals was applied to sediments of various rivers and lakes. There are many rivers basins in Turkey. Sakarya River Basin is one of the most ...
-
(ELSEVIER, 2012)In this study, 9-acrylamidoacridine (VAc) was synthesized by the reaction of 9-aminoacrydine (Ac) and acryloyl chloride and characterized by elemental analysis, FUR, NMR spectroscopy. The photophysical properties of VAc ...
-
(ELSEVIER SCIENCE INC, 2012)Selective and synergistic extraction of cadmium from acidic iodine solutions containing Cd2+, Co2+ and Ni(2+)using solvent extraction (SX) technique is presented in this study. The study has highlighted the importance of ...
-
(SPRINGER, 2012)The clinoptilolite which was modified with sodium and potassium chloride was found to have adsorption capacity for rhodium. To evaluate the adsorption capacity and characteristics, the effects of solution pH, dose of ...
-
(SPRINGER-VERLAG WIEN, 2001)Tetrasubstituted phthalocyanines bearing four dihexylmalonate or dihexylhexylmalonate residues on the periphery (M[Pc(CH(COOC6H13)(2))(4)] or M[Pc(C(COOC6H13)(2)C6H13)(4)]; M = Pd(II), Cu(II), Co(II)) were synthesized from ...
-
(EDAM, 2012)Many studies have been carried out because of the importance of values education in recent years. The studies have shown their effects on the curriculum of 2005. In many classes it is aimed to provide individuals with the ...
-
(ROYAL SOC CHEMISTRY, 2012)We have described highly selective 1(4), 8(11), 15(18), 22(25)-(1-hydroxyhexan-3-ylthio)-phthalocyanine sensors, M{Pc[alpha-SCH(C3H7)(C2H5OH)](4)} (MPc(alpha-HHT)(4), where M = Zn(II) (2), Cu(II) (3) or Co(II) (4) and HHT: ...
-
(AMER CHEMICAL SOC, 2012)Transformation of c-yclohexa-2,4-diene-1,2-diylbis(methylene) diacetate to various carbasugars is described. Photooxygenation of a cyclohexadiene derivative gave a bicyclic endoperoxide, which was reduced with thiourea to ...
-
(WORLD SCI PUBL CO INC, 2012)This work demonstrated preparation, characterization, and application of a cobalt phthalocyanine based enzymeless/mediatorless hydrogen peroxide sensor. The cobalt phthalocyanine (CoPc) was retained in polyaniline (PANI) ...
-
(SOC CHEMISTS TECHNOLOGISTS MADECONIA, 2012)Radical oxidation and addition reactions of anthracene (1), 9-methylanthracene (2) and 9-phenylanthracene (3) were investigated with dimethyl malonate (4) in the presence of ceric ammonium nitrate (CAN) and manganese(III) ...
-
(ELSEVIER SCIENCE BV, 2012)The optical properties of 2(3),9(10),16(17),23(24)-tetrakis-{6-(-benzofuran-2-carboxylate)-hexylthio} phthalocyaninatozinc(II) {Zn[Pc(b-S(CH2)(6)OCOBz-furan)(4)], (ZnPcBzF) thin film prepared by spin coating method were ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2012)A newly series of 6-(phenylurenyl/thiourenyl) saccharin (6a-y) derivatives were synthesized and their inhibitory effects on the diphenolase activity of banana tyrosinase were evaluated. A 70-fold purification of the enzyme ...
-
(SPRINGER INTERNATIONAL PUBLISHING AG, 2012)An alternative method has been developed for the anomeric deacetylation of fully acetylated carbohydrate derivatives using zinc acetate dihydrate as a catalyst in methanol under mild conditions. The experimental simplicity, ...
-
(TAYLOR & FRANCIS LTD, 2012)Selenium (Se) is an important trace element for human and animal health. It accumulates in wheat and corn, which is consumed mostly as bread. The Turkish population consumes mainly white wheat, whole wheat (brown bread) ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2012)The synthesis, characterization and photophysical properties of the tetra- {6-(-benzofuran-2-carboxylate)-hexylthio} substituted copper(II), cobalt(II), manganese(III) and zinc (II) phthalocyanines, {M[Pc(beta-S(CH2)(6)O ...
-
(AMER CHEMICAL SOC, 2012)1,3,3a,7a-Tetrahydro-2-benzofuran was used as key compound for the synthesis of various bishomoinositol derivatives. The diene was subjected to an epoxidation reaction for further functionalization of the diene unit. The ...
-
(MARCEL DEKKER INC, 2001)Reaction of dichloroketone 2 with NEt3 gave indenone (4) in high yield. Catodic reaction of 2 in the presence of C/Pt electrodes afforded the rearranged product 3 in high yield besides a small amount of chlorohydroxyketone ...
