(+)-CSA Catalyzed Multicomponent Synthesis of 1-[(1,3-Thiazol-2-ylamino)methyl]-2-naphthols and Their Ring-Closure Reaction under Ultrasonic Irradiation
(Hindawi Ltd, 2016)
New 1-[(1,3-thiazol-2-ylamino)methyl]-2-naphthols were obtained by condensation of 2-aminothiazole, aromatic aldehydes, and 2-naphthol in the presence of (+)-camphor-10-sulfonic acid ((+)-CSA) as an effective catalyst under ...
Synthesis, photophysical, photochemical and electrochemical properties of crown ether bearing coumarin substituted phthalocyanines
(Elsevier Science Sa, 2012)
Zinc (II), cobalt (II) and copper (II) phthalocyanines substituted at the peripheral (complexes 5, 6 and 7) and non-peripheral (complexes 8, 9 and 10) positions with 7,8-(15-crown-5)-3-(4-oxyphenyl)coumarin groups have ...
Trace metal and radionuclide pollution in marine sediments of the Aegean Sea (Izmir Bay and Didim)
(Springer, 2013)
To determine radioactivity and trace metal levels, surface sediments were collected from two important areas (A degrees zmir Bay and Didim) in the Aegean Sea region of Turkey, and were analyzed for concentrations of Po-210, ...
Molecular structure and phase change properties of various polymer-doped liquid crystal
(Elsevier Science Bv, 2019)
In this study, the electro-optical and phase transition properties of 4-cyano-4'-n-pentylbiphenyl (5CB) liquid crystal doped by various polymers have been investigated. New liquid crystals were synthesized by doping 5CB ...

Solutions of local fractional sine-Gordon equations
(Taylor & Francis Ltd, 2019)
In this paper, we study sine-Gordon equation in order to obtain exact solitary wave solutions in the domain of fractional calculus. By using the definition of conformable fractional derivative, we obtain analytical solutions ...
A computational technique for determining the fundamental unit in explicit types of real quadratic number fields
