(Elsevier Science Sa, 2011)
The synthesis, spectroscopic and electrochemical properties of the tetra-(3-ferrocenyl-7-oxycoumarin)substituted zinc (II) and cobalt (II) phthalocyanines (3 and 4) are reported for the first time. The synthesis of novel ...
Descriptive statistics and risk assessment for the control of seasonal pollutant effects of Po-210 and Pb-210 in coastal waters (Canakkale, Turkey)
(Springer, 2018)
Po-210 is absorbed into the human body by seafood intake. Especially, mollusks and mussels are known to have much higher Po-210 concentration than fish among various other types of seafood and are consumed in large quantities ...
The influence of thickness and ammonia flow rate on the properties of AlN layers
(Elsevier Sci Ltd, 2012)
Undoped AlN layers have been grown on c-plane sapphire substrates by metal-organic chemical vapor deposition in order to study the effects of ammonia (NH3) flow rate and layer thickness on the structural quality and surface ...
Synthesis of Au-doped magnetic nanocomposites: structural, magnetic, and catalytic properties
(Springer, 2021)
In this work, Fe3O4 magnetic nanoparticles (MNPs) were produced using the co-precipitation method. The surface of the produced MNPs was covered with TEOS and APTES as a shell and the APTES shell is doped with Au nanoparticles ...

(Istanbul Univ, Fac Medicine, Publ Off, 2015)
Objective: To evaluate the superiority of the most performed tests; lamellar body counts and TDxFLM test compared to each other to estimate the maturation of fetal lungs and also to evaluate the reasons for the unclear ...
Optimization of parameters for alpha-amylase production under solid state fermentation by Trichothecium roseum
(Ars Docendi, 2011)
The production of extracellular alpha-amylase by Trichothecium roseum was studied in solid state fermentation (SSF). The effects of wheat bran (WB), rye straw (RS). corncob leaf (CL), sunflower oil meal (SOM) and rice husk ...
Monte Carlo simulations and forecasting of Radium-226, Thorium-232, and Potassium-40 radioactivity concentrations
(Springer, 2020)
This study depicts the radioactivity time series levels of Ra-226, Th-232, and K-40 prospectively by Monte Carlo simulations (MCSs). Three ARIMA stationary stochastic processes are used with measurement records statistical ...
Synthesis, characterization, and swelling behavior of poly(N-hydroxymethylacrylamide) grafted poly(vinyl alcohol)
(Wiley, 2020)
In this study, the graft copolymerization of N-hydroxymethylacrylamide (NHMAAm) with poly(vinyl alcohol) (PVA) was carried out by using potassium persulfate/N,N,N,N-tetramethylethylenediamine (K2S2O8) to improve physicochemical ...
