Activity Coefficient of Triton X100 and Brij S20 in the Infinitely Diluted Micellar Pseudophase of the Binary Micelle Triton X100–Brij S20 in the Water Phase at the Temperature Interval T = (283.15–318.15) K
Journal of Chemical & Engineering Data, 2019Co-Authors: Mihalj Poša, Ana PilipovićAbstract:Activity coefficients of the infinitely diluted micellar pseudophase are equal to parameters of the second-order Margules Function: Ln φi∞ = aij and Ln φj∞ = aji. The excess chemical potential of the infinitely diluted micellar pseudophase can be expressed using partial molar enthalpy (hiE,∞) and entropy (siE,∞), extrapolated in the infinitely diluted state: μiE,∞ = RT Ln φi∞ = hiE,∞ – TsiE,∞. The binary mixture of surfactants Triton X100–Brij S20 is not a symmetric binary mixture. In the temperature interval T = (283.15–318.15) K, the activity coefficient for Triton X100 = i in the infinitely diluted micelle pseudophase is Ln φi∞ 0, hiE,∞ > 0), ...

Thermal electron attachment to chlorinated alkenes in the gas phase
Chemical Physics Letters, 2017Co-Authors: K. Wnorowski, J. Wnorowska, Bartosz Michalczuk, A. Jówko, W. BarszczewskaAbstract:Abstract This paper reports the measurements of the rate coefficients and the activation energies of the electron capture processes with various chlorinated alkenes. The electron attachment processes in the mixtures of chlorinated alkenes with carbon dioxide have been investigated using a Pulsed Townsend technique. This study has been performed in the temperature range (298–378) K. The obtained rate coefficients more or less depended on temperature in accordance to Arrhenius equation. The activation energies ( E a ’s) were determined from the fit to the experimental data points with Function Ln( k ) = Ln( A ) − E a / k B T . The rate coefficients at 298 K were equal to 1.0 × 10 −10 cm 3 s −1 , 2.2 × 10 −11 cm 3 s −1 , 1.6 × 10 −9 cm 3 s −1 , 4.4 × 10 −8 cm 3 s −1 , 2.9 × 10 −12 cm 3 s −1 and 7.3 × 10 −12 cm 3 s −1 and activation energies were: 0.27 eV, 0.26 eV, 0.25 eV, 0.21 eV, 0.55 eV and 0.42 eV, for trans -1,2-dichloroethylene, cis -1,2-dichloroethylene, trichloroethylene, tetrachloroethylene, 2-chloropropene, 3-chloropropene respectively.

Kinetics of low energy electron attachment to some fluorinated alcohols in the gas phase
Chemical Physics Letters, 2014Co-Authors: K. Wnorowski, Janina Kopyra, J. Wnorowska, Iwona Szamrej, Bartosz Michalczuk, W. BarszczewskaAbstract:Abstract Thermal electron attachment processes in the mixtures of CH 3 CH 2 OH, CF 3 CH 2 OH, CF 3 CF 2 CH 2 OH, (CF 3 ) 2 CHOH and CH 3 CH(OH)CF 3 with carbon dioxide have been investigated using an electron Pulsed Townsend technique. Measurements were carried out in the temperature range (298–413) K. The obtained rate coefficients depended on temperature in accordance to Arrhenius equation. From the fit to the experimental data points with Function Ln( k ) = Ln( A )− E a / k B T the activation energies ( E a ’s) were determined. The rate coefficients at 298 K are equal to 3.2 × 10 −13 cm 3 s −1 , 5.1 × 10 −11 cm 3 s −1 , 1.1 × 10 −10 cm 3 s −1 , 3.0 × 10 −10 cm 3 s −1 and 2.6 × 10 −11 cm 3 s −1 and activation energies are: 0.37 eV, 0.25 eV, 0.28 eV, 0.20 eV and 0.23 eV, respectively for CH 3 CH 2 OH, CF 3 CH 2 OH, CF 3 CF 2 CH 2 OH, (CF 3 ) 2 CHOH and CH 3 CH(OH)CF 3 .

Some New Inequalities Between Important Means
arXiv: Classical Analysis and ODEs, 2007Co-Authors: Jamal Rooin, Mehdi HassaniAbstract:In this paper, mainly using the convexity of the Function $\frac{a^x-b^x}{c^x-d^x}$ and convexity or concavity of the Function $\Ln\frac{a^x-b^x}{c^x-d^x}$ on the real line, where $a>b\geq c>d>0$ are fixed real numbers, we obtain some important relations between various important means of these numbers. Also, we apply the obtained results to Ky Fan type inequalities and get some new refinements.
