Influence of sodium dodecyl sulfate on the reaction between Nile Blue A and hydrogen peroxide
(Srpsko hemijsko društvo, Beograd, 1999)
The influence of the anionic surfactant sodium dodecyl sulfate on the rate of the reaction between the cationic form of Nile Blue A and hydrogen peroxide was investigated in the pH range from 5 to 8.5. A retardation of the ...
The physicochemical and thermodynamic properties of the choline chloride-based deep eutectic solvents
(Srpsko hemijsko društvo, Beograd, 2017)
This paper reports the physicochemical (density, dynamic viscosity, electrical conductivity and refractive index) and the thermodynamic (thermal expansion coefficient, molecular volume, lattice energy and heat capacity) ...
Spectrophotometric determination of fluocortolone in tablets using 1,4-dihydrazinophthalazine / Spektrofotometrijsko određivanje fluokortolona u tabletama sa reagensom 1,4-dihidrazinoftalazinom
(Srpsko hemijsko društvo, Beograd, 2000)
The proposed method for the determination of fluocortolone is based on the formation of a stable, yellow coloured hydrazone product with 1,4-dihydrazinophthalazine as the reagent. Heating at 85 °C for 2 h was found to be ...
Development and validation of a fluorometric method for the determination of hesperidin in human plasma and pharmaceutical forms / Razvoj i validacija fluorimetrijske metode za određivanje hesperidina u humanom serumu i farmaceutskim preparatima
(Srpsko hemijsko društvo, Beograd, 2012)
A fluorometric method, based on the fluorescence properties of the aluminium(III)-hesperidin complex, for the determination of hesperidin in human plasma and pharmaceutical forms has been developed and validated. The complex ...
New evidence of transient complex oscillations in a closed, well-stirred belousov-zhabotinsky system / Novozabeležene tranzijentne kompleksne oscilacije u zatvorenom belousov-žabotinski reakcionom sistemu sa dobrim mešanjem
(Srpsko hemijsko društvo, Beograd, 2006)
Some new experimental evidence of complex irregular oscillations in the Belousov-Zhabotinsky reaction realized in a batch reactor is presented. The results were obtained under relatively low cerium and malonic acid ...
An electrochemical study of the adsorptive behaviour of varenicline and its interaction with DNA / Elektrohemijsko ispitivanje adsorpcije i interakcije vareniklina i DNK
(Srpsko hemijsko društvo, Beograd, 2012)
The electrochemical behaviour of a novel nicotinic α4β2 subtype receptor partial agonist varenicline (VAR), which is used for smoking cessation, was investigated in Britton-Robinson buffers (pH 2.0-12.0) by cyclic, ...
Determination of nitrate by the IE-HPLC-UV method in the brain tissues of Wistar rats poisoned with paraquat / Određivanje nitrata IE-HPLC-UV metodom u moždanim tkivima Wistar pacova trovanih parakvatom
(Srpsko hemijsko društvo, Beograd, 2007)
This work was a part of an initial study regarding the involvement of reactive nitrogen species (RNS) in paraquat (PQ) neurotoxicity. The nitrate concentration in the vulnerable regions of the brain (cortex, striatum and ...
Application of experimental design in the examination of the dissolution rate of carbamazepine from formulations. Characterization of the optimal formulation by DSC, TGA, FT-IR and PXRD analysis
(Srpsko hemijsko društvo, Beograd, 2015)
Poor solubility is one of the key reasons for the poor bioavailability of carbamazepine drugs. This study considers formulation of solid surfactant systems with carbamazepine, in order to increase its dissolution rate. ...
