Removal of Mg from spring water using natural clinoptilolite
(Mineralogical Soc, Twickenham, 2012)
Natural zeolitic tuff from Brus (Serbia) consisting mostly of clinoptilolite (about 90%) has been investigated for the reduction of the Mg concentration in spring water. The sorption capacity of the zeolite is relatively ...
Modeling of carriers mobility impact on CNT FIET current-voltage characteristics
(Natl Inst Optoelectronics, Bucharest-Magurele, 2014)
In this paper, field effect transistor with active area made of carbon nano tubes (CNT FET), is investigated. At the beginning, CNT characteristics, structure and possibilities of their implementation as a FET channel, are ...
FTIR investigation of solvent effects of N-methyl and N-tert-butyl benzamide
(Maik Nauka/Interperiodica/Springer, New York, 2014)
Infrared spectroscopy studies of N-methyl benzamide and N-tert-butyl benzamide in 12 organic solvents were undretaken to investigate solvent-solute interactions. The wavenumbers of carbonyl stretching vibration nu(C=O) in ...
Electrochemical determination of sertraline in pharmaceutical formulation and serum using a gold electrode in a pH 8.4 bicarbonate solution
(Monatshefte Fur Chemie, 2021)
The electrochemical characterization of sertraline at gold electrode was examined by cyclic voltammetry measurements (CV) in pH 8.4 bicarbonate buffer. Then Au electrode was evaluated for the quantitative determination of ...
Temperature effect on decorative gold coatings obtained from electrolyte based on mercaptotriazole - comparison with cyanide
(Carl Hanser Verlag, Munich, 2014)
The aim of this work was to investigate the effect of temperature on the thickness, surface roughness, visual appearance and morphology of electrochemically deposited gold decorative coatings obtained from conventional ...
Spectroscopy study of Bi12GeO20 single crystals
(Natl Inst Optoelectronics, Bucharest-Magurele, 2013)
In this work single crystals of bismuth germanium oxide (Bi12GeO20) have been grown by the Czochralski method. Growth conditions were studied. The critical diameter and the critical rate of rotation were calculated. Suitable ...
Two-Stage Fermentation for 2-Ketogluconic Acid Production by Klebsiella pneumoniae
(Korean Soc Microbiology & Biotechnology, Seoul, 2014)
2-Ketogluconic acid production by Klebsiella pneumoniae is a pH-dependent process, strictly proceeding under acidic conditions. Unfortunately, cell growth is inhibited by acidic conditions, resulting in low productivity ...
Substituent effects on chromatographic retention data of 5-arylidene-2,4-thiazolidinediones in qsar methodology
(Taylor & Francis Inc, Philadelphia, 2014)
Quantitative structure-retention relationship (QSRR) study of retention data of thirteen 5-arylidene-2,4-thiazolidinediones obtained by reversed phase HPTLC. The effect of substituents attached to aryliden ring on the ...
Phase rigidity of point interactions
(World Scientific Publ Co Pte Ltd, Singapore, 2013)
In this paper, we investigate phase rigidity of one-dimensional point interactions. With the aid of supersymmetric quantum mechanics (SUSYQM) we generate family of isospectral potentials describing point interactions. We ...
Enhanced Arsenic Sorption by Hydrated Iron (III) Oxide-Coated Materials-Mechanism and Performances
(Water Environment Federation, 2011)
Mechanism and performances of arsenic(III) [As(III)] and arsenic(V) [As(V)] sorption onto hydrated iron(III) oxide (HFO)-coated materials were investigated at neutral pH where arsenic occurs in both molecular and ionic ...
