Kinetics, mechanism, and equilibrium studies of the reactions between a ruthenium(II) complex and some nitrogen- and sulfur-donor nucleophiles
Aleksandar M. Mijatović, Ratomir M. Jelić, Jovana Bogojeski, Živadin D. Bugarčić, Biljana Petrović (2013)Kinetika i mehanizam reakcija supstitucije između [Ru(trpi)(bpi)Cl]+ sa nukleofilima gvanozin-5′-monofosfatom, L-histidinom, tioureom i dimetilsulfoksidom proučavani su spektrofotometrijski u 0,1 M NaClO4 na 310 K. Red reaktivnosti za odabrane ligande je: tiourea > gvanozin-5′-monofosfat > L-histidin > DMSO. Ovaj red je povezan sa elektronskim, strukturnim i hemijskim karakteristikama kompleksa i nukleofila. Reakcija supstitucije sa tioureom je proučavana na tri različite temperature (288, 298 i 310 K). Negativna entropija aktivacije DS = potvrđuje asocijativni način aktivacije. Formiranje kompleksa [Ru(trpi)(bpi)H2O]2+ sa ligandima ...... material (Table 4S). Calculated values for the rate constants at 288 and 298 K are k1 288 = 0.31 ± 0.02 M-1s-1 and k1 298 = 0.92 ± 0.04 M-1 s-1. Finally, a negative value for the entropy of activation, DS= = -105 ± 5 K-1M-1, confirms the fact that the substitution reaction between [Ru(trpy)(bpy)Cl] ...

Determining the Groundwater Balance and Radius of Influence Using Hydrodynamic Modeling: the Case Study of the Groundwater Source “Šumice” (Kikinda, Serbia)
A groundwater flow model was developed to simulate groundwater extraction from the public water supply source of the City of Kikinda. The hydrodynamic model includes the municipal groundwater source of Kikinda (Šumice and the Jezero Well), but also an extended area where there are groundwater sources that provide water supply to three factories: (MSK, TM and LŽT - Kikinda). Hydrodynamic modeling, based on the numerical method of finite differences will show the groundwater balance of the sources in the ......
