Araştırmanın amacı okulöncesi öğretmenlerinin fen eğitimine karşı tutumları ve fen etkinliklerine ilişkin yeterliliklerinin bazı değişkenlere göre incelenmesidir. Veri toplama araçları olarak, “Fen Eğitimine Karşı Tutum” ...

We investigated the cytotoxic effects of the newly synthesized cyclotriphosphazene derivatives on A2780 (ovarian), PC-3 and LNCaP (prostate) cancer cell lines. 4′-hydroxy-substituted-chalcone compounds (2–8) were reacted ...

The present study introduces cyclotriphosphazene compounds substituted by dioxyphenylcoumarin as a photodiode application. Firstly, 7,8-dihydroxy-3-(3-methylphenyl)coumarin (1b) has been obtained by conventional as well ...

The cyclotriphosphazene compound (2) bearing formyl groups as side groups was obtained from the reaction of 2,2-Dichloro-4,4,6,6-bis[spiro(2′,2″-dioxy-1′,1″-biphenylyl)]cyclotriphosphazene (1) with 4-hydroxy-3-methoxybenzaldehyde ...

The present study was designed to both synthesize phenylacrylonitrile compounds (1a–k) and their anti-tumor activities on human breast cancer cell line (MCF-7) were determined. The structures of all the compounds were ...

The new hexasubstitue-cyclophosphazene compounds containing chalcone derivatives (2–11) were obtained from the reactions of hexachlorocyclotriphosphazene (1) with several hydroxy chalcones in K2CO3/acetone system. All ...

Solvent free synthesis of 6,7-dihydroxy-3-(3- chlorophenyl) coumarin (CFHC) was designed and obtained by the interaction of 2-(2,4,5-trimethoxyphenyl)- 1-(3-chlorophenyl)acrylonitrile with pyridinium hydrochloride in ...
