Determination of protonation constants of some 3-alkyl(aryl)-4-(ptert- butyl(benzyl/benzyliden)amino)-4,5-dihydro-1H-1,2,4-triazole-5- one deriveatives with spectrophotometric method
(2011)
The protonation constant values of different twelve 3-alkyl(aryl)-4-(p-t-butyl(benzyl/ benzyliden)amino)-4,5-dihydro-1H-1,2,4-triazole-5-one derivatives have been determined in ethanol %50 - water %50 mixtures by ...
Study of microwave surface resistance of type-II superconductors carrying transport current
(Wiley, 2011)
We investigate the microwave surface resistance of an infinitely long type-II superconductor in the critical state carrying transport DC current, in the absence and in the presence of external magnetic fields. Calculations ...
A T-partial order obtained from T-norms
(2011)
A partial order on a bounded lattice L is called t-order if it is defined by means of the t-norm on L. It is obtained that for a t-norm on a bounded lattice L the relation a ?T b iff a = T(x,b) for some x ? L is a partial ...
Structural characterization of aniline-bentonite composite by FTIR, DTA/TG, and PXRD analyses and BET measurement
(Taylor & Francis, 2011)
The aniline species incorporated into the acid-activated bentonite matrices leads to the decay of the skeletal stretches centered at 1041 cm-1 and the rise of new features in the phenyl ring frequency region, 1700-1400 ...
Structural and optical properties of ZnO thin films by the spin coating Sol-Gel method
(Kluwer Academic Publishers, 2011)
ZnO thin films were deposited onto glass subsrates by a Sol-gel spin coating method. The structural and optical properties of ZnO thin films were investigated. The molar ratios of the zinc acetate dihydrate to Monoethanolamine ...
Chemical composition and antimicrobial activity of the essential oils from the flower, leaf, and stem of Senecio pandurifolius
(2011)
The essential oils from the fresh flower, leaf, and stem of Senecio pandurifolius (Asteraceae) were isolated by hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. A total of forty-five, ...
Novel coordination polymers of metal(II) succinates with 4-aminopyridine: Synthesis, spectroscopic, thermal, and fluorescent properties
(Wiley, 2011)
Four novel divalent transitional metal succinates (suc) with 4-aminopyridine (apy), [M(apy)2(H2O)2(?-suc) ]n [M = Ni (1), Co (2)] and [M(apy)2(H2O)(suc)] [M = Cu (3), Zn (4)] were synthesized and characterized by elemental ...
Syntheses, crystal structures, fluorescent, and thermal properties of nickel(II) 5,5-diethylbarbiturate complexes with (2-aminomethyl), (2-aminoethyl), and (2-hydroxyethyl)pyridines
(Taylor & Francis, 2011)
Three nickel(II) complexes of 5,5-diethlybarbiturate (barb) with (2-aminomethyl)pyridine (ampy), (2-aminoethyl)pyridine (aepy), and (2-hydroxyethyl)pyridine (hepy), [Ni(barb-N)2(ampy)2] (1), [Ni(barb-N,O)(aepy)2](barb)·H2O ...
The relations between antioxidant enzymes and chlorophyll fluorescence parameters in common bean cultivars differing in sensitivity to drought stress
(Springer, 2011)
Effects of the antioxidant system and chlorophyll fluorescence on drought tolerance of four common bean (Phaseolus vulgaris L.) cultivars were studied. The cultivars were positioned in the order of a decrease in their ...
Antimicrobial activity and volatile constituents of omphalodes cappadocica (Willd.) DC.
(2011)
The composition of the essential oil isolated by hydrodistillation from Omphalodes cappadocica (Willd.) DC. (Boraginaceae) collected from 'Of', a town in Trabzon, was determined by GC-FID and GC-MS. Sixty components were ...
