On the spin density wave electron gas
(Society of Physical Chemists of Serbia, 2004)
The possibility of a non-trivial ground state of an electron gas in metal featuring a spin density wave (SDW) was widely discussed. We investigated the collective spectrum (CS) of a spin density wave electron gas using the ...
Mechanically activated ceria
(Society of Physical Chemists of Serbia, 2004)
The reduction of comercial and mechanically activatedCeO2 powder at 1200 °C in an argon atmosphere was examined by XRD. Mechanical activation of oxide powder was performed by milling in a vibratory mill for different lengths ...
Adsorption isotherms of chloroform on macroporous copolymers determined by inverse gas chromatography
(Society of Physical Chemists of Serbia, 2004)
The inverse gas chromatography (IGC) under finite surface coverage conditions was used for the determination of adsorption isotherms of chloroform on macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol ...
Time depended inhibition of SPMs Na+ /K+ -ATPase induced by cadmium and lead
(Society of Physical Chemists of Serbia, 2004)
In this work, time depended interaction of SPMs Na+ /K+ -ATPase with Cd2+ and Pb2+ by single exposure and in the mixture, was investigated. The possibility to selectively detect these ions on the basis on the rate of their ...
Determination of the point of zero charge of alumina by batch equilibration method
(Society of Physical Chemists of Serbia, 2004)
In this work we present the points of zero charge, pHpzc, of five commercial alumina samples, of an alumina/solution ratio of 0.100g/25 ml, obtained by batch equilibration method. As an inert electrolyte, KNO3 of 0.001 - ...
Derivative spectrophotometric determination of partition coefficient of hydrochlorothiazide between cetyltrimethylammonium bromide micelles and water
(Society of Physical Chemists of Serbia, 2004)
The interaction of hydrochlorothiazide (HCT), benzothiadiazine diuretic, with cationic surfactant cetyltrimethylammonium bromide (CTAB) was studied as a model system for drug/membrane interactions. From the dependence of ...
Determination of the ionization constants of 2,4-DIIODO-6-methylphenyl carbamoylmethyl iminodiacetic acid
(Society of Physical Chemists of Serbia, 2004)
The ionization constants of 2,4-diiodo-6-methylphenylcarbamoylmethyl iminodiacetic acid were determined: pK1 1.3 (the first carboxylic group), pK2 2.52 (the second carboxylic group), pK3 5.86 (amino group) and pK4 10.85 ...
HPLC and spectrophotometric investigation of the formation of Sn(II)-p-aminohippuric acid complex in perchlorate medium
(Society of Physical Chemists of Serbia, 2004)
The complex equilibrium in tin(II)-p-aminohippuric acid (PAH) solutions in perchlorate medium was investigated. HPLC, spectrophotometric and pH-metric methods were used. The experimental results have shown that week ...
Ab initio calculations of some time –dependent properties of atomic systems
(Society of Physical Chemists of Serbia, 2004)
Within the framework of the many-body theory by using the method of Random Phase Approximation with Exchange we calculated the polarizabilities, the refractive index and Verdet of Ar and Be atoms.
Design and test of the gas-dynamic carbon dioxide laser experimental setup
(Society of Physical Chemists of Serbia, 2004)
An experimental gas-dynamic laser apparatus based on acetylene-in-oxygen combustion has been designed and tested. Main setup volume was designed as a modular type for flexibility. A vacuum system, electrical and measuring ...
