Synthesis of novel 1,10-phenanthroline derivatives and it used as probes for sensitive detection of Zn2+ and Cd2+ metal ions - Spectroscopic and theoretical approach
(PERGAMON-ELSEVIER SCIENCE LTD, 2019)
A novel class of unexpected 1,10-phenanthrolinederivatives were synthesized from 2,3-dihydroacridin-4(111)ones with 3-aminonaphthalen-2-carboxylic acid in presence of phosphorus oxychloride at 130 degrees C and simple ...
Synthesis and characterization of a composite polymeric material including chelating agent for adsorption of uranyl ions
(ELSEVIER SCIENCE BV, 2017)
In this study, a versatile polymeric material was synthesized by grafting Calcon Carboxylic Acid (CCA), which is known as a chelating agent for some metal ions, to polyacrylamide (PAA) structure. Thus, the adsorptive ...
Absolute ion hydration enthalpies from absolute hardness and some VBT relationships
(ELSEVIER SCIENCE BV, 2018)
In the present work, absolute hydration enthalpies are calculated from ion absolute hardness for a series of +1 and -1 ions. The calculated values are compared with those previously reported (Housecroft, 2017) [2] and ...
Determining the strain upon the eastern section of the North Anatolian fault zone (NAFZ)
(SPRINGER HEIDELBERG, 2015)
Strain analysis is frequently used by disciplines such as material, tensile strength, mechanics, and soil mechanics. Strain causes deformation based on normal, shear, and torsional strain types. Strain cannot be measured ...
The investigation of Cu(II) removal by biocomposites synthesized with the immobilization of R. delemar and Candida microorganisms
(DESALINATION PUBL, 2017)
In this study, Cu(II) adsorption using the biocomposites prepared by the immobilization of chitosan polymer and Candida yeasts (Candida lipolytica, Candida membranaefaciens, Candida tropicalis, Candida utilis) and ...
A new method for calculation of molecular hardness: A theoretical study
(ELSEVIER SCIENCE BV, 2015)
The chemical hardness introduced by Pearson in 1960s is an extremely useful theoretical descriptor. It is apparent that principles such as hard and soft acids and bases (HSAB) and maximum hardness principle (PMH) related ...
Tularemia in children: evaluation of clinical, laboratory and therapeutic features of 27 tularemia cases
(TURKISH J PEDIATRICS, 2012)

Zeta Potentials and Isoelectric Points of Biomolecules: The Effects of Ion Types and Ionic Strengths
(ELECTROCHEMICAL SCIENCE GROUP, 2012)
A systematic study of the zeta potential and isoelectric point of biomolecules such as BSA, amylase, invertase and phenylalanine has been performed in various salt solutions for 0.001 M and 0.1 M ionic strenght. Chloride ...
Does Islam deter crime in a secular Islamic country? The case of Turkey
(TAYLOR & FRANCIS LTD, 2016)
'Does Islam deter crime in a secular country like Turkey' is the research question for which the current study tries to find a tentative answer. The data came from 619 undergraduate university students, 352 academic and ...
Pd(II) complexes of novel phosphine ligands: Synthesis, characterization, and catalytic activities on Heck reaction
(TAYLOR & FRANCIS LTD, 2016)
Novel phosphine oxides, (((3-methylpyridin-2-yl)amino)methyl)diphenylphosphine oxide (1) and diphenyl((pyrazin-2-ylamino)methyl)phosphine oxide (2), were synthesized and characterized. Phosphines ligands (3 and 4) were ...
