Antimicrobial and cytotoxic evaluation of new quinazoline derivatives
(Natural Product Incorporation, 2016)
The synthesis of nine new quinazoline derivatives (2a-2i) and evaluation of their antimicrobial and cytotoxic activities were aims of the present work. For the synthesis of the compounds, 2-chloro-6,7-dimethoxyquinazolin-4-amine ...
Lead removal from industrial waste
(Hitit University, 2017)
In this study, the heavy metal removal performance of poly(2-hydroxyethyl methacrylate-N-methacryloyl-(L)-histidine methyl ester), poly(HEMA-MAH) cryogel, a known polymer, in HNO3 was investigated. To determine the heavy ...
Synthesis and structures of Fe(II), Zn(II) and Pd(II) complexes with a schiff base derived from methyl 2-amino-6-methyl-4,5,6,7-tetrahydrothieno[2,3-c] pyridine-3-carboxylate and comparison of their optical constants for different solvents and molarities
(American Scientific Publishers, 2017)
Schiff base derived from condensation of o-vanillin (3-methoxysalicylaldehyde) and methyl 2-amino-6-methyl- 4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxylate and its metal complexes are synthesized and characterized ...
Development of a flow-injection with spectrophotometric method for total iron in water samples
(Hacettepe University, 2017)
Asimple spectrophotometric flow-injection method is reported for the highly sensitive and fast determination of iron(III) and total iron. The method is based on the formation of iron(III)- (1-nitroso-2-naphthol-3,6 sulphonate) ...
Optimization of the schiff-base reaction of acetylacetone with biogenic amines
(Hitit University, 2017)
In this work, optimum conditions for the derivatization reaction of biogenic amines (histamine, tyramine, putrecine, tryptamine, phenylethylamine, cadaverine, spermidine and spermine) with acetylacetone have been determined. ...
Coal an impure fuel source: Radiation effects of coal-fired power plants in Turkey
(Hacettepe Üniversitesi, 2010)
Turkish coal is generally poor quality and the levels of chemical and radiological toxic trace elements in it are higher with respect to mean values of activity concentrations given in United Nations Scientific Committee ...
Characterization of boron doped Cobalt/Zinc acetate composite fibers
(Hacettepe University, 2009)
PVA/cobalt acetate/zinc acetate doped with boron composite fibers were prepared by electrospinning technique. Electrospinning was performed by putting solutions at different applied voltage in a range from 13 to 18 kV. The ...
Nanofibers by electrospinning of nylon 6 doped with boron
(Hacettepe University, 2009)
In this study, Nylon 6 was successfully cross-linked with boron using formic acid as solution. Electrospinning process was performed by putting hybrid nylon 6/boric acid solutions at different applied voltage in a range ...
Grafting density of oligo-bottle-brushes on silicon surface: effect of mole fraction of RAFT agent-functionalized alkenes in mixed self-assembled monolayers
(Taylor and Francis Inc., 2020)
The purpose of the study is to prepare of novel oligo-(N-(2-hydroxypropyl) methacrylamide)-g-poly(lactic acid) bottle-brushes with different grafting density on the silicon surface. Firstly, the mixtures of 9-decen-1-ol ...
Novel coordination compounds: Mn(II), Co(II), Ni(II), Cu(II), and Zn(II) cations with acesulfame/N,N-diethylnicotinamide ligands
