چکیده مقاله:

The possibility of hydroxylamine electrochemical determination over a CoO(OH)-modified electrode, accompanied by complex-formation, has been studied from the theoretical point of view. The correspondent mathematical model has been developed and analyzed by means of linear stability theory and bifurcation analysis. It was shown that CoO(OH) may be applied as an efficient electrode modifier in the detection of hydroxylamine in neutral and slightly alkaline media. The electrochemical response has to be clear and easy to interpret. The possibility of the oscillatory and monotonic instabilities has also been verified.

Electrochemical reduction of oxygen with iron phthalocyanine in neutral media

Recent interest in electricity production using microbial fuel cells makes it important to better understand O2 reduction in neutral solutions with non-precious metal catalysts. Higher O2 reduction activity was obtained using iron phthalocyanine supported on Ketjen black carbon (FePc-KJB) than with a platinum catalyst in neutral pH. At low overpotentials, a Tafel slope close to -0.06 V/dec in b...

Social media enhances languages differentiation: a mathematical description

Understanding and predicting the evolution of competing languages is a topic of high interest in a world with more than 6000 languages competing in a highly connected environment. We consider a reasonable mathematical model describing a situation of competition between two languages and analyse the effect of the speakers' connectivity (i.e. social networks). Surprisingly, instead of homogenizin...

Tomographical Imaging and Mathematical Description of Porous Media Used for the Prediction of Fluid Distribution

Flow and transport processes in porous media depend on the geometric properties of their pores, where the diameters typically range from micrometers to millimeters. In this study, we mapped the pore structure of glass bead and sand columns using tomography with X-rays, thermal neutrons, and synchrotron radiation. Utilizing X-rays from tubes, we mapped two 2.5and 5.3-cm-diam. sand samples that c...

Mathematical Description of the Implementation of the Adaptive Newton-Raphson Method in Compositional Porous Media Flow

Models for multiphase-multicomponent flow in porous media are described in systems of PDEs. Solving them using finite difference discretization method can be of three ways; explicit, semi-implicit, and fully implicit. In this study, we present the implementation of an adaptive Newton-Raphson method in the context of IMPECS (Implicit Pressures Explicit Concentrations and Saturations) method of s...
