On a variational problem due to the B-Darboux frame in Euclidean 3-space
(Wiley, 2021)
In this paper, we introduce a new frame which is called the B-Darboux frame on a surface in Euclidean 3-space. We know that the parallel transport frame is derived from the Frenet frame along a space curve on a surface. ...
Structural and catalytic properties of Fe3O4 doped Bi2S3 novel magnetic nanocomposites: p-Nitrophenol case
(Elsevier Sci Ltd, 2020)
Catalytic properties of Bi2S3 nanostructures, Fe3O4 nanoparticles and novel Bi2S3@Fe3O4 magnetic nanocomposites were investigated. Flower-like Bi2S3 nanostructures were produced using hydrothermal synthesis. Bi2S3 ...
Evaluation of electronic transport and optical response of two-dimensional Fe-doped TiO2 thin films for photodetector applications
(Elsevier Gmbh, 2020)
We have carried out the structural, electronic and optical properties of Iron (Fe)-doped TiO2 thin films by sol-gel technique. The results reveal that the thin films form in a granular structure where particle-like grains ...
CSA-Catalyzed Three-component Synthesis of Fused Polycyclic Pyrazolo[4,3-e]pyridines Under Ultrasonic Irradiation and Their Antioxidant Activity
(2017)
New fused pyrazolo[4,3-e]pyridines were obtained by three-component reaction of 1,3-dimethyl-1H-pyrazol-5-amine or 3-phenyl-1H-pyrazol-5-amine, aromatic aldehydes and indan-1,3-dione in the presence of camphor-10-sulfonic ...
A novel approach to Chromium rejection from sewage wastewater by pervaporation
(Elsevier, 2021)
Pervaporation is an effective method, especially in the separation of azeotropic mixtures or in the recovery of some components from the mixtures. Although various methods have been used for the treatment of chromium-containing ...
A GLIMPS TO THE MODERN OPTICIANRY TECHNIQUES
(Kırklareli Üniversitesi, 2021)
Millions of people are suffering from eye refractive errors such as myopia, hypermetropia, astigmatism, presbyopia, etc. Every day, modern opticianry techniques were used to diagnose and treat the patients. And they find ...
Determination of Minimum Enzymatic Decolorization Time of Reactive Dye Solution by Spectroscopic & Mathematical Approach
(Office Spectroscopy & Spectral Analysis, 2015)
Synthetic dyes are very important for textile dyeing, paper printing, color photography and petroleum products. Traditional methods of dye removal include biodegradation, precipitation, adsorption, chemical degradation, ...
Optoelectronic investigation of Cu2FeSnS4 quaternary functional photodiodes with IR detection capabilities
(Elsevier, 2021)
Cu2FeSnS4 semiconductor used in the preparation of quaternary photodiodes was synthesized using hydrothermal synthesis. The nanoparticles were then spin coated on a silicon substrate. Nanoparticles were characterized using ...
Synthesis, characterization, and photophysical and photochemical properties of 3-(4-phenyloxy)coumarin containing metallo- and metal-free phthalocyanines
(2014)
The synthesis of novel zinc, cobalt, indium, and metal-free phthalocyanines carrying four 3-(4-phenyloxy)couma- rins in the periphery/nonperiphery were prepared by cyclotetramerization of 3-[4-(3,4-dicyanophenyloxy)phenyl]coumarin ...
Determination of Titanium in Zinc ash by FAAS After Digested using Ultrasound-Assisted Extraction
(Kırklareli Üniversitesi, 2021)
In this study, it is aimed to determine the amount of Ti (titanium) in waste ash samples taken from galvanizing factories by using flame atomic absorption (FAAS). Various time periods and different solvent mixtures were ...
