Density functional theory study of the magnetic coupling interaction in a series of binuclear oxalate complexes
(Springer Wien, Wien, 2012)
Magnetic couplings in oxalate-bridged binuclear complexes, namely five isomers of [(VO)(2)(ox)(SCN)(6)](4-), trans-(equatorial, equatorial), cis-(equatorial, equatorial), trans-(axial, axial), cis-(axial, axial), and (axial, ...
DFT and MM description of the structure and magnetic properties of manganese complexes with X-phenylcyanamido bridging ligand
(Springer Wien, Wien, 2011)
Magnetic properties of the complexes [Mn(3-Clpcyd)(H(2)O)-(phen)(2)](+), [{Mn(3-Fpcyd)(MeOH)(phen)}(2)(mu-3-Fpcyd)(2)], [{Mn(3-Fpcyd)(EtOH)(phen)}(2)(mu-3-Fpcyd)(2)], [{Mn(3-Clpcyd)(MeOH)(phen)}(2)(mu-3-Clpcyd)(2)], and ...
Kinetic Analytical Method for Determination of Uric Acid in Human Urine using Analyte Pulse Perturbation Technique
(Sociedade Brasileira de Química, 2012)
Simple and reliable novel methods for the determination of uric acid (UA) are proposed and validated. For quantitative determination of UA, two matrices were used: the Bray-Liebhafsky (BL) oscillatory reaction in a stable ...
Fractionation, Mobility, and Contamination Assessment of Potentially Toxic Metals in Urban Soils in Four Industrial Serbian Cities
(Springer, New York, 2018)
The main soil properties, concentrations of selected elements (As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn), and the chemical speciation of each element were determined in urban soil samples taken from urban parks in four Serbian ...
Magnetic criteria of aromaticity in a benzene cation and anion: how does the Jahn-Teller effect influence the aromaticity?
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
The aromatic/antiaromatic behavior of the Jahn-Teller UT) active benzene cation and anion has been investigated using Density Functional Theory (DFT) calculations of Nuclear Independent Chemical Shifts (NICS) and magnetic ...
A comparative study of the electrochemical properties of carbon nanotubes and carbon black
(Elsevier, 2009)
Two samples of commercial multi-walled carbon nanotubes (Sigma-Aldrich and Sun Nanotech) and a sample of carbon black (Vulcan XC-72R) were investigated in raw state and after the activation in nitric and sulfuric acid by ...
Influence of composition of the magnetic composite coating on the performance of the optical fiber magnetic field sensing element
(Journal of Optoelectronics and Advanced Materials, 2007)
The optical fiber magnetic sensing element (OFMSE) based on the optical fiber coated with composite coating polymermagnetic powder has been already introduced in magnetic field sensing. In this research, the rapid quenched ...
