Psilocin is thereby oxidized yielding either micro- or macromolecular product, being both of them important for the economical and green conducting polymer composite for electrocatalysis, electroanalysis and energy conversion. The analysis of the correspondent mathematical model confirms, that, despite of the high probability of the oscillatory behavior, the electrochemical process is efficient from both analytical and synthetical point of view.

El análisis del modelo matemático correspondiente mediante la teoría de estabilidad lineal y análisis de bifurcaciones ha mostrado que el comportamiento de este sistema se hace bastante semejante al ya observado durante la “paradoja de politiofeno”. Así, hay una mayor probabilidad del acaecer las inestabilidades oscilatoria y monotónica. El polímero, por su vez, se obtendrá con una conductividad reducida y morfología menos uniforme.

Research paper thumbnail of The Theoretical Description for Chlorantraniliprole Electrochemical Determination, Assisted by Squaraine Dye – Nano-CuS Composite

The correspondent reaction mechanism has been proposed, and the correspondent mathematical model has been developed and analyzed by means of linear stability theory and bifurcation analysis. It has been shown that the chlorantraniprole electrochemical anodical determination on high potential may be efficiently provided by cupper sulfide nanoparticles, stabilized by the squaraine dye. On the other hand, the oscillatory and monotonic instability is also possible, being caused by DEL influences of the electrochemical stage. DOI: http://dx.doi.org/10.17807/orbital.v13i3.1518

Research paper thumbnail of The Theoretical Description for Magnesium Chlorate Electrochemical Determination on a Magnezone-XC Modified Electrode

The process involves the complex formation of magnesium cation with the azo dye Magnezone XC and the electropolymerization of the resulting complex compound in the presence of the chlorate-ion by two parallel mechanisms. The correspondent mathematical model has been developed and analyzed by means of linear stability theory and bifurcation analysis. It has been shown that from both electroanalytical and electrosynthetical points of view the system is efficient. The linear dependence between the electrochemical parameter and salt concentration is obtained easily, and the material formed during the electroanalytical process is highly conductive and catalytic. On the other hand, the oscillatory behavior in this system will be caused by double electric layer influences on both complexation and electropolymerization stages.

The correspondent mathematical model has been developed and analyzed by means of linear stability theory and bifurcation analysis. By analysis of the model it was shown that the squaraine dye and vanadium oxyhydroxide may serve as efficient electrode modifiers for neotame electrochemical determination. The linear dependence between the concentration and current is realized in a vast range of parameters. On the other hand, the oscillatory and monotonic instabilities are also viable.

Metformin oxidation is realized via assisted electrochemical 1,2,4-triazole formation, followed by its polymerization and N-oxidation. The correspondent mathematical model has been developed and analyzed by means of linear stability theory and bifurcation analysis. It has shown that the neutral and basic media are more efficient for metformin electrochemical determination than acidic media, due to the absence of the influences of non-protonated aminogroupsand, furtherly, pyridinic nitrogen atoms to double electric layer (DEL) ionic force, conductivity and impedance. In these conditions, the electrochemical instabilities are less capable to realize and, therefore, the linear dependence between the analyte concentration and the current of the system will be easier to obtain and maintain, as no side r...

A detecção eletroanalítica é realizada mediante um mecanismo híbrido, envolvendo ou não a formação de novos compostos iônicos. É possível mostrar que o estado estacionário é estabilzado, apesar de a região topológica, que lhe é correspondente, ser mais estreita que no caso da detecção mais comum. O comportamento oscilatório, neste caso, é mais provável que nos casos mais comuns, mas o fator adicional é relacionado apenas com a introdução de um composto de ligação.
