Phenols were nitrated regioselectivity with NH4NO3 in the presence of KHSO4 as a catalyst in high yields. Key Words: Nitration, Phenols, NH4NO3, KHSO4.

In the recent years, vibrational spectroscopies (infrared spectroscopy) have been developed for all sorts of analysis in microbiology. Important features of these methods are the relative ease with which measurements can be performed. Fourier transform infrared spectroscopy (FT-IR) is a…

In this study, the seed germination characteristics of Salvia cyanescens a plant which is endemic for Turkey and the effects on germination rates of such factors as temperature, alkaline metal salt (NaCl, KNO3) and acid (H2SO4) concentrations and growth-regulating (GA3)…

Two different groups of compositions for 80B2O3 + 15Na2O + (5-x) Al2O3 + (x) V2O5 and 85B2O3 + 10Na2O +(5-x) Al2O3 + (x) V2O5 (where x=1; 0.5 wt %) glass samples were prepared by quenching technique and doped with Cu2+…

Multiple linear regression models are widely used applied statistical techniques and they are most useful devices for extracting and understanding the essential features of datasets. However, in multiple linear regression models problems arise when a serious outlier observation or multicollinearity…

System suitability test (SST) is a test to determine the suitability and effectiveness of chromatographic system prior to use. The performance of any chromatographic system may continuously change during their regular use, which can affect the reliability of the analytical…

H-point standard addition method (HPSAM) was applied to kinetic data for simultaneous determination of Ni(II) and Mn(II). The method is based on the difference between rate of complexation of 1-(2-pyridylazo)-2- naphthol (PAN) with Ni(II) and Mn(II) at pH 7.5 in…

The inhibition of copper corrosion by two new Schiff bases under 0.5 M H2SO4 at 25oC was studied by electrochemical tests (potentiodynamic polarization and AC impedance technique).These studies have shown that two Schiff bases are good inhibitors for copper in…

This paper introduces a novel fusion scheme, called EMP Fusion, which has the promise of achieving breakeven and realizing commercial fusion power. The method is based on harnessing the power of an electromagnetic pulse generated by the now well-developed flux…

This study describes an integrated water budget model of Develi Closed Basin. Sultansazlığı Wetland, being as one of the seven important wetlands and the second important bird habitat of Turkiye, is placed in Develi Closed Basin. In the recent years,…
