The investigation of efficient conditions for alumina production from diasporic bauxites

Alp, Ahmet; Aydın, Ali Osman (METALLURGICAL SOC-C I M, 2002)

The main objective of this study was to investigate the leach conditions of diasporic bauxites in the region of Mugla-Milas for alumina production. The chemical composition was 57.91% Al2O3,, 21.33% Fe2O3, 3.84% SiO2, 2.20% ...
Synthesis and tyrosinase inhibitory properties of novel isoquinoline urea/thiourea derivatives

Genç Bilgiçli, Hayriye; Zengin, Mustafa (INFORMA HEALTHCARE, 2014)

A new series of isoquinoline urea/thiourea derivatives (1-11) were synthesized, and their inhibitory effects on tyrosinase were evaluated. Isoquinoline urea/thiourea derivatives were obtained as a result of the reaction ...
Investigation of inhibitory effects of triazole derivatives on the protease enzymes

Arabacı, Gülnur (RESEARCH JOURNAL BIOTECHNOLOGY, 2014)

Triazoles constitute an important class of heterocyclic organic compounds because of their wide range of applications as pharmaceutical agents. They have common mode of action like inhibiting ergosterol synthesis, decreasing ...
A NEW ANTISEPTIC - FURFURYLAMINE BIGUANIDINE DERIVATIVE SYNTHESIS AND ITS EFFECT ON MULTI-DRUG RESISTANT ACINETOBACTER BAUMANNII STRAINS

Öğütlü, Aziz; Genç Bilgiçli, Hayriye; Zengin, Mustafa; Karabay, Oğuz (CARBONE EDITORE, 2014)

Objective: The number of antiseptics used in a hospital environment are limited, hence some of them are restricted because of resistance. Furfurylamine biguanidine HCl (FBC) and furfurylamine biguanidine acetate (FBA) are ...
Doping of poly(o-phenylenediamine): Spectroscopy, voltammetry, conductivity and band gap energy

Olgun, Uğursoy; Gülfen, Mustafa (ELSEVIER SCIENCE BV, 2014)

In the present work, poly(o-phenylenediamine) (PoPDA) were synthesized by the chemical oxidation reaction of o-phenylenediamine (o-PDA) with ammonium persulfate ((NH4)(2)S2O8) (APS) as the oxidant. The chemical structure ...
Synthesis of Spirocyclic and Tricyclic Isoxazoline via 1,3-Dipolar Cycloaddition Reactions

Tutar, Ahmet (WILEY, 2014)

1,3-Dipolar cycloadditions of the bicyclic monoterpenes (S)-(-)-camphene (1), (R)-(+)-a-pinene (2), and (S)-(-)-b-pinene (3) with aryl and heteroaryl nitrile oxides afforded new spirocyclic and tricyclic isoxazoline ...
Physical properties of the cubic spinel LiMn2O4

Bulut, Emrah (PERGAMON-ELSEVIER SCIENCE LTD, 2014)

We have performed an ab initio study of structural, electronic, magnetic, vibrational and thermal properties of the cubic spinel LiMn2O4 by employing the density functional theory, the linear-response formalism, and the ...
Synthesis of fluorescence poly(phenylenethiazolo[5,4-d]thiazole) copolymer dye: Spectroscopy, cyclic voltammetry and thermal analysis

Olgun, Uğursoy; Gülfen, Mustafa (ELSEVIER SCI LTD, 2014)

In the present work, poly(phenylenethiazolo[5,4-d]thiazole) copolymer dye were synthesized by the reaction of terephthalaldehyde and rubeanic acid. The synthesized copolymer was characterized by different spectroscopic ...
Ag(I) and Pd(II) sensing, H- or J-aggregation and redox properties of metal-free, manganase(III) and gallium(III) phthalocyanines

Günsel, Armağan; Bilgiçli, Ahmet Turgut (ELSEVIER SCI LTD, 2014)

H- or J-aggregation, Ag(I) and Pd(II) sensing and redox behaviours of novel a-substituted free-base (2), manganase(III) (3) and gallium(III) (4) phthalocyanines bearing 1-hydroxy hexane-3-ylthio moieties have been studied. ...
Synthesis, characterization and electrochemistry of novel differently octasubstituted phthalocyanines

Kandaz, Mehmet; Yaraşır, Meryem Nilüfer (PERGAMON-ELSEVIER SCIENCE LTD, 2002)

We describe the complete synthesis of differently substituted multifunctional metallo phthalocyanines (MPcs) (M = Ni, Zn, Cc) bearing four 2'-aminophenylsulfanyl or 2-aminophenoxy moieties and four chloro atoms on peripheral ...
Quantitative Determination of Glycine in Aqueous Solution Using Glutamate Dehydrogenase-Immobilized Glyoxal Agarose Beads

Yılmazer Keskin, Semra; Keskin, Can Serkan (HUMANA PRESS INC, 2014)

In this study, an enzymatic procedure for the determination of glycine (Gly) was developed by using a column containing immobilized glutamate dehydrogenase (GDH) on glyoxal agarose beads. Ammonia is produced from the ...
