Antimicrobial activity and a comparative essential oil analysis of Centaurea pulcherrima Willd. var. pulcherrima extracted by hydrodistillation and microwave distillation
(Taylor & Francis Online, 2012)
The essential oils of Centaurea pulcherrima Willd. var. pulcherrima (Asteraceae) were isolated by hydrodistillation (HD) and a microwave distillation (MD), than characterised by GC-FID and GC-MS. A total of 58 and 57 ...
Poly(vinylferrocenium) perchlorate-polyaniline composite film-coated electrode for amperometric determination of hydroquinone
(Springer, 2012)
Poly(vinylferrocenium) perchlorate-polyaniline (PVF +-PANI) composite film was synthesized electrochemically on Pt electrode in a methylene chloride solution containing a mixture of poly(vinylferrocene) (PVF) polymer and ...
Variation in body size and age structure among three Turkish populations of the treefrog Hyla arborea
(Brill, 2012)
To determine how climate factors influence age, body size and sexual size dimorphism (SSD) in the Mediterranean region, we generated data on age and body size of the European Treefrog, Hyla arborea, in three Turkish ...
Radioactivity and heavy metal concentrations in food samples from Rize, Turkey
(Wiley, 2012)
BACKGROUND: Rize in Turkey was contaminated by the Chernobyl accident in 1986. A comprehensive study was planned and carried out to determine the radioactivity levels and heavy metal concentrations in four food categories ...
Chemical constituents and antimicrobial activity of the essential oil from vicia dadianorum extracted by hydro and microwave distillations
(2012)
The aim of this research was to investigate the influence of extraction methods on yield and chemical composition of the essential oil of Vicia dadianorum Somm. & Lev. The volatiles of V. dadianorum have been isolated by ...
Current transport mechanism in CdS thin films prepared by vacuum evaporation method at substrate temperatures below room temperature
(Elsevier, 2012)
CdS thin films were deposited by vacuum deposition method at low substrate temperatures instead of the commonly used vacuum deposition at high substrate temperatures (T S > 300 K). The effect of low substrate temperature ...
Scorzonera ahmet-duranii sp. nov. (Asteraceae) from southwest Anatolia, and its phylogenetic position
(2012)
Scorzonera ahmet-duranii S. Makbul & Coskuncelebi sp. nov. (Asteraceae) is described and illustrated as a new species endemic to Turkey. It is morphologically similar to S. semicana DC., but differs by its rootstock, deeply ...
Structural and optical properties of ZnO and Al-doped ZnO microrods obtained by spray pyrolysis method using different solvents
(Elsevier, 2012)
ZnO and Al-doped ZnO microrods were obtained by spray pyrolysis method using different solvents such as methanol and propanol. The effect of the type of solvent in the starting solution on the structural, morphological and ...
Investigation of structural and optical properties of ZnO films co-doped with fluorine and indium
(Elsevier, 2012)
Undoped ZnO film and ZnO films, which are co-doped with F and In (FIZO) at different concentrations, were synthesized by sol-gel technique and the effects of co-doping of F and In on structural and optical properties of ...
Design and synthesis of new 1,2,4-triazole deriaties containing morpholine moiety as antimicrobial agents
(TÜBİTAK, 2012)
2-Morpholine-4ylethyl-3H -1,2,4-triazole-3-ones (2a, 2b) were obtained from the condensation between the corresponding ethoxycarbonylhydrazones and 2-morpholinoethanamine. 2a was conerted to acetohydrazide (4) ia the ...
