(2015)TwoN-heterocyclic carbene (NHC) palladium complexes of formula [PdBr2(NHC)(pyridine)] in which thecarbenic ring is anked by sterically crowded cavitand substituents were prepared from appropriate imidazolium saltsbearing ... -
A simple and efficient approach for preconcentration of some heavy metals incosmetic products before their determinations by ame atomic absorptionspectrometry
(2016)In the current study, a simple and efficient analytical method for preconcentration and determination ofCd(II), Pb(II), and Sn(II) in some cosmetic samples, using ultrasonic assisted-cloud point extraction and ame ... -
Sivas 4 Eylül Barajı Su Kalitesi-Seviye İlişkisinin Coğrafi Bilgi Sistemi (CBS) İle Haritalanması
(2018)Göl ve barajlara gelen ve buradan çıkan kirletici yüklerin oluşturacağı etki, uzun bir zaman dilimi içinde ortaya çıkmaktadır. Su ortamlarında kirlenmeyi belirleyen belli başlı kriterler fizikokimyasal ve biyolojik ... -
Some Heavy Metal Contents of Various Slaughtered Cattle
(2017)As a result of environmental pollution and food chain, heavy metals may accumulate in human or animal bodies. Toxic metals cause inhibition on chemical and enzyme reactions in cells. Therefore, a negative situation forms ... -
Surfactant-sensitized spectrophotometric determination of Hg(II) in water samples using 2-(2-thiazolylazo)- p-cresol as ligand and cetylpyridinium chloride as cationic surfactant
(2012)A new, reliable, surfactant-sensitized method is described for the spectrophotometric determination of total and dissolved inorganic mercury at trace levels. The method is based on the ternary complex formation of Hg(II) ... -
Synthesis, molecular docking, and antitumoral activity of alnustone-like compounds against estrogen receptor alpha-positive human breast cancer
(2015)Abstract: Alnustone-like compounds are promising inhibitors for estrogen receptor \alpha (ER-\alpha), which is a novel cancer therapeutic target. Therefore, 10 alnustone-like compounds with substituents at the phenyl rings ... -
Theoretical Investigation of Corrosion Inhibition of Iron Metal by Some Benzothiazole Derivatives: A Monte Carlo Study
(2017)It is important to note that atomistic modeling and simulations are becoming increasingly popular in the field of corrosion inhibition of metal surfaces. In this work, we investigated the adsorption properties and corrosion ... -
A USEFUL METHOD FOR THE PREDICTION OF MOLECULAR ELECTROPHILICITY AND NUCLEOPHILICITY
(2016)In the present study, new theoretical model for the calculation of molecular electrophilicity and molecular nucleophilicity based on group electronegativity and molecular hardness equations, derived by us in recent years, ... -
Validation of the Charge Equalization Principles during the Formation of Small Molecules
(2017)The electrophilicity equalization principle recently presented by Chattaraj and his co-workers has been criticized by Szentpaly. In the present report, we found that the charge equalization process for small molecule is ... -
