AB  - The study presents a mathematical model of Bruk Temkin-Gorodsky Novakovic (BT-GN) reaction system employing palladium-catalyzed oscillatory carbonylation reaction of mono alkyne-terminated poly(ethylene glycol) methyl ether. The proposed model advances simulation capabilities of this particular chemical oscillator but also BT-GN reactions in general. The model was verified using experimental data where good agreement is achieved and existence of complex pH oscillations like burst oscillations was matched. Furthermore, the model was used to predict reaction conditions capable of producing further complexities and initial conditions that would lead to desired period of pH oscillations. Having such a powerful tool, enhances our capabilities to study and further develop BT-GN oscillators with a reduced experimental effort.

AB  - A kinetic method for the determination of l-tyrosine (Tyr) by analyte pulse perturbation, caused by different amounts of Tyr, in the Bray–Liebhafsky (BL) oscillatory reaction realized in a continuous-flow stirred tank reactor, is proposed. For such purposes, the BL oscillating reaction was kept in a stable non-equilibrium stationary state close to the bifurcation point and was used as the matrix reaction system. Under optimum reaction conditions, the linear relationship between the kinetic parameters, Δτ2 (the period between first two oscillations that appear after applied perturbation) as well as τend (the time elapsed between the perturbation of the BL reaction by Tyr and the termination of the oscillatory phase) and the Tyr concentrations is obtained over the ranges 1.1 × 10− 6 − 9.2 × 10− 6 mol L− 1 and 1.1 × 10− 6 − 1.4 × 10− 5 mol L− 1, with the limit of detections of 6.6 × 10− 7 mol L− 1 and 6.4 × 10− 7 mol L− 1. The described method that relies on a simple instrumental set-up, has been successfully applied to the determination of Tyr in a dietary supplement. Some aspects of the possible mechanism of Tyr action on the BL oscillator are discussed.

AB  - The first discovered homogeneous oscillatory reaction was the Bray-Liebhafsky (BL) one, 
described in a paper published exactly 100 years ago. However, the applicability of oscillatory 
reactions in chemical computing was recently discovered. Here we intend to expose the native 
computing concept applied to intermittent states of the BL reaction, because we believe that 
this particular state may have some advantages. For this purpose, numerical simulations will be
used based on the known model. Sequences of perturbations will be introduced by adding iodate 
(IO3

) and hydrogen peroxide (H2O2), separately, as well as in various combinations with one 
another. It will be shown that dynamic states obtained after perturbations with same species 
depend very much on the sequence in which these species were used in perturbations. 
Additionally, it will be shown that obtained dynamic states shift the system from chaotic 
intermittent dynamic state to different complex periodic states. Hence, the applicability of the 
BL reaction system in chemical computing was demonstrated.

AB  - Dynamic states with intermittent oscillations consist of a chaotic mixture of large
amplitude relaxation oscillations grouped in bursts, and between them, small-amplitude
sinusoidal oscillations, or even the quiescent parts, known as gaps. In this study,
intermittent dynamic states were generated in Bray–Liebhafsky (BL) oscillatory reaction in
an isothermal continuously-fed, well-stirred tank reactor (CSTR) controled by changes of
specific flow rate. The intermittent states were found between two regular periodic states
and obtained for specific flow rate values from 0.020 to 0.082 min−1 . Phenomenological
analysis based on the quantitative characteristics of intermittent oscillations, as well
as, the largest Lyapunov exponents calculated from experimentally obtained time
series, both indicated the same type of behavior. Namely, fully developed chaos
arises when approaching to the vertical asymptote which is somewhere between two
bifurcations. Hence, this study proposes described route to fully developed chaos in
the Bray-Liebhafsky oscillatory reaction as an explanation for experimentally observed
intermittent dynamics. This is in correlation with our previously obtained results where the
most chaotic intermittent chaos was achieved between the periodic oscillatory dynamic
state and stable steady state, generated in BL under CSTR conditions by varying
temperature and inflow potassium iodate concentration. Moreover, it was shown that,
besides the largest Lyapunov exponent, analysis of chaos in experimentally obtained
intermittent states can be achieved by a simpler approach which involves using the
quantitative characteristics of the BL reaction evolution, that is, the number and length
of gaps and bursts obtained for the various values of specific flow rates.

AB  - Two hydroxyanthraquinones, alizarin and purpurin, that have been used throughout
history as a natural pigment, were extracted from roots of Rubia tinctorum from
Serbia. As substances with important chemical activities and, therefore, with wide
applications (for example in dyeing textile fabrics as well as in pharmacy because of
their anti-inflammatory, anti-cancer, antiviral, antimicrobial and antioxidant activities,
etc.) they were analyzed in the kinetically very sensitive Bray–Liebhafsky (BL)
oscillatory reaction. However, although they are both, hydroxyanthraquinones it is
shown that their interactions with BL nonlinear reaction system differ significantly.
Consequently, two different reactions were used to explain the mechanism of their
chemical activities. The numerical simulations based on a standard model of the BL
oscillatory reaction together with proposed reactions due to alizarin/purpurin interactions
with a matrix are correlated with experimental investigations. Moreover, it
is shown that very small amounts of alizarin and purpurin (from about 1 × 10–7 M)
produce the response of the BL matrix such that micro-quantitative analysis based
on the BL oscillatory reaction can be successfully performed in this reaction system.
The linear response of the BL matrix on the presence of alizarin and purpurin
(necessary for microquantitative determination) is analyzed as a function of two
concentration sensitive parameters: pre-oscillatory period τ1 and potential shift after
perturbation ΔE.

AB  - The reaction mechanism of palladium-catalysed oscillatory carbonylation of
poly(ethylene glycol)methyl ether acetylene (PEGA) was examined by stoichiometric
network analysis (SNA) of the stability of the dynamic states. The previously published
simplified reaction network proposed to account for the experimentally observed results was
modified in order to obtain a more realistic reaction network for the investigated process. In the modified reaction network, the direct autocatalytic steps were replaced with autocatalytic
loops. In this procedure some complex net reactions had to be resolved, while some new
reactions had to be taken into account, altering the reaction mechanism responsible for the
appearance of oscillation. Moreover, in the modified reaction network, the expressions for
reaction rates correspond formally to their stoichiometry in accordance to mass action
kinetics. The SNA identified the instability condition which was further tested and confirmed
by numerical simulation.

Hence, we use the bifurcation diagram of the Bray-Liebhafsky reaction performed in continuous well-stirred tank reactor under controlled temperature variations for the determination of the activation energies as well as rate constants of particular steps appearing in the kinetic model of oscillatory reaction mechanism. This approach has led us to the development of general procedure for treatment of experimentally obtained data and extracting kinetic parameters from them, which was very important considering that some rate constants of the already proposed model could not be determined experimentally and have to be fitted (or guessed). Also, the proposed approach has the potential to inspire the refinement of already proposed models and the development of a new one that will be able to reproduce experimentally obtained system's dynamical features more successfully. In particular, the dynamic states of the Bray-Liebhafsky oscillatory reaction have been analyzed experimentally and numerically using already proposed model together with qualitative and quantitative analysis of bifurcation diagrams in both cases.

AB  - The effect of different concentration of gallic acid (GA) on the oscillatory behavior of the Briggs-Rauscher (BR) reaction is reported. In this work, the sample was injected before the start of oscillations. The main effect is the appearance of an induction time that increases with the concentration of GA added. Other parameters as a number of oscillations and oscillatory period are 
affected. These latter linearly depend on the concentration and can be used for quantitative GA analytical assay in a GA concentration range 3.00×10-5 M − 4.00×10-4 M. The perturbation is very different from that previously reported, in which samples of phenolics were added to an active BR mixture, indicating that the mechanism of perturbation largely depends on the injection point.

AB  - The system KSCN-H2O2-CuSO4-NaOH, also known as the OrbA n-Epstein oscillatory reaction, is exposed to external perturbations by several phenolic compounds: catechol, resorcinol, hydroquinone, 2,5-dihydroxybenzoic acid, 2,6-dihydroxybenzoic acid, 2,3-dihydroxybenzoic acid, 2,4-dihydroxybenzoic acid, 3,4-dihydroxybenzoic acid, 3,5-dihydroxybenzoic acid, caffeic acid, and ferulic acid. As a result of the performed perturbation in most examined cases, oscillations have been inhibited for some characteristic time, and resumed afterwards. The evaluated inhibition time is typical for each substance and strongly dependent on its concentration. The chemical mechanism of the interaction between the OrbA n-Epstein system and phenolic compounds is briefly discussed. Numerical simulations are performed using the original OrbA n-Epstein model with 30 reactions, extended by three reactions describing the interaction with inhibitory substances. The rate constants of three added reactions are adjusted to fit experimental inhibition times, and compared among used compounds. The observed effects are discussed further in relation with the bond dissociation enthalpy theory. Unlike other tested compounds, 2,5-dihydroxybenzoic acid remains off from predicted order of activity.

AB  - Stoichiometric Network Analysis (SNA) is a powerful method that can be used to examine instabilities in modelling a broad range of reaction systems without knowing the explicit values of reaction rate constants. Due to a lack of understanding, SNA is rarely used and its full potential is not yet fulfilled. Using the oscillatory carbonylation of a polymeric substrate [poly(ethylene glycol) methyl ether acetylene] as a case study, in this work, we consider two mathematical methods for the application of SNA to the reaction models when conservation constraints between species have an important role. The first method takes conservation constraints into account and uses only independent intermediate species, while the second method applies to the full set of intermediate species, without the separation of independent and dependent variables. Both methods are used for examination of steady state stability by means of a characteristic polynomial and related Jacobian matrix. It was shown that both methods give the same results. Therefore, as the second method is simpler, we suggest it as a more straightforward method for the applications. Published by AIP Publishing.

AB  - Chaotic dynamic states with intermittent oscillations were generated in a Bray-Liebhafsky (BL) oscillatory reaction in an isothermal open reactor i.e., in the continuously-fed well-stirred tank reactor (CSTR) when the inflow concentration of potassium iodate was the control parameter. They are found between periodic oscillations obtained when [KIO3](0)  LT  3.00 x 10(-2) M and stable steady states when [KIO3](0) > 4.10 x 10(-2) M. It was shown that the most chaotic states obtained experimentally somewhere in the middle of this region are in high correlation with results obtained by means of largest Lyapunov exponents and phenomenological analysis based on the quantitative characteristics of intermittent oscillations.

AB  - Intermittent oscillations as a chaotic mixture of large amplitude relaxation oscillations, grouped in bursts and small-amplitude sinusoidal ones or even quiescent parts between them known as gaps, were found and examined in the Bray-Liebhafsky (BL) reaction performed in CSTR under controlled temperature variations. They were obtained in a narrow temperature range from 61.0 degrees C to 63.1 degrees C, where 61.0 degrees C is the critical temperature for burst emergence from the stable steady state and 63.1 degrees C is the critical temperature for gap emergence from regular oscillations. Since intermittencies appear gradually from the regular oscillatory state, and no hysteresis was obtained with decreasing/increasing temperature in the vicinity of these two bifurcations, a linear relationship between (tau(B)/tau)(2) and (tau(G)/tau)(2) (where tau(B), tau(G) and tau denotes duration of bursts, gaps, and whole experiment, respectively), as a function of the temperature as the control parameter, was expected and obtained. Although these intermittent oscillations are chaotic with respect to the lengths of individual gaps as well as bursts, their deterministic behavior related to temperature was additionally established. Thus, the number of bursts or gaps per unit of time (N-B/tau and N-G/tau) has the form of a normal distribution function over the temperature range in the region where intermittencies are obtained. Temperature dependence of the Lyapunov exponents was also described by a function of the normal distribution form. Hence, we established some regularities in the chaotic behavior of intermittent oscillations that are common in life but difficult for determinations.

AB  - The mathematical analogy between properties of simple and complex models of non-linear reactions was used to determine reaction steps in the complex model, necessary to generate instability region and appropriate type of bifurcations on the border between stable and unstable non-equilibrium stationary state. The autocatalator was recognized as the simple prototype two-variable non-linear model practical for examination of the complex four-variable non-linear neuroendocrine system known as the Hypothalamic-Pituitary-Adrenal (HPA) axis. In both cases, we derived the instability criteria by stoichiometric network analysis (SNA), determine conditions under which dynamic transitions, i.e. bifurcations occur, and identify the type of bifurcation. The supercritical Andronov-Hopf bifurcation was found in both cases whereas saddle-node bifurcation was detected only in the model for HPA axis. Thus, by stoichiometric network analysis, the mathematical analogy is found between two different models with same autocatalytic steps, that is, between two models with easily recognizable qualitative analogy.

AB  - In stoichiometric network analysis (SNA) the instability condition is calculated by the current rates. Recently, we have shown that in the final result the current rates can be substituted by reaction rates, which is a more appropriate value for the examination of instability from experimental point of view. Here, we elaborate the problem of whether the current rates are necessary parameters in the calculation, with the aim of obtaining the region of instability. All calculations are performed on a model for Belousov-Zhabotinsky (BZ) reaction, which has not been examined by SNA.

AB  - The intermittency or intermittent bursting as the type of dynamic state when two qualitatively different behaviors replace one another randomly during the course of the reaction, although all the control parameters remain constant, is found in the Briggs Symbol of the Klingon Empire Rauscher oscillating system moderated by a very small amount of phenol. Within a range of phenol concentrations, the oscillation amplitude is diminished considerably, and after oscillations cease, they repeat intermittently, giving several bursts of oscillations. For the concentrations used here, the range of phenol concentrations where intermittent bursting oscillations occur in a closed reactor is ca. 1.8x10(-5) to 3.6x10(-5) M. Bursting also occurs in an open reactor and can be sustained indefinitely at 5.53x10(-5) M concentration. The intermittent bursting behavior is robust, and can be achieved at a variety of conditions.

AB  - Perturbation of the BrayLiebhafsky non-oscillating subsystem (mixture of KIO3 and H2SO4), i.e., Dushman reaction (DR), by piroxicam (PX), was observed in an open reactor, i.e., in the continuously fed well-stirred tank reactor (CSTR). Monitoring the response of DR to perturbations by different concentrations of PX allows developing a simple procedure for quantitative determination of this analyte in both bulk drug and pharmaceutical preparation (injection). A tentative perturbation mechanism of PX action on the DR matrix, based on a kinetic scheme that was suggested by Agreda etal., is proposed. The PX reactivity in DR has been generally related to the reaction of PX with hypoiodous acid (HIO) present in the matrix.

AB  - The mixed-mode dynamical states found experimentally in the concentration phase space of the iodate catalyzed hydrogen peroxide decomposition (The Bray-Liebhafsky oscillatory reaction) are discussed theoretically in a related multiple-time-scale model, from the viewpoint of tourbillion. With aim to explain the mixed-mode oscillations obtained by numerical simulations of the various dynamical states of a model for the Bray-Liebhafsky reaction under CSTR conditions, the folded singularity points on the critical manifold of the full system and Andronov-Hopf bifurcation of the fast subsystem are calculated. The interaction between those singularities causes occurrence of tourbillion structure.

With aim to explain the mixed-mode oscillations obtained by numerical simulations of the various dynamical states of a model for the Bray-Liebhafsky reaction under CSTR conditions, the folded singularity points on the critical manifold of the full system and Andronov-Hopf bifurcation of the fast subsystem are calculated. The interaction between those singularities causes occurrence of tourbillion structure.",

AB  - By numerical calculations based on our previously proposed model with Br2O intermediate species we were able to simulate complex evolution of the Belousov-Zhabotinsky (BZ) reaction under batch conditions. In the defined region of initial malonic acid concentration [MA](0) (1.00 x 10(-3) mol dm(3) a parts per thousand currency sign [MA](0) a parts per thousand currency sign 1.50 mol dm(-3)) different sequences of regular and complex periodic and aperiodic oscillations were obtained. It is noticed that the bromine evaporation significantly affects the dynamics of the reaction.

AB  - Simple and reliable novel methods for the determination of uric acid (UA) are proposed and validated. For quantitative determination of UA, two matrices were used: the Bray-Liebhafsky (BL) oscillatory reaction in a stable non-equilibrium stationary state close to the bifurcation point (method A) as well as, the BL non-oscillating subsystem (mixture KIO3 and H2SO4), i.e., Dushman reaction (DR) in a steady state (method B). The proposed methods are optimized in a continuously fed well stirred tank reactor (CSTR) and applied with excellent results in the determination of UA in human urine samples. The linear relationship between maximal potential shift Delta E-m, and both the logarithm of the UA concentration (procedure A) and UA concentration (procedure B) is obtained in the concentration range 2.98 x 10(-5)-2.68 x 10(-4) mol L-1 and 2.98 x 10(-5)-3.58 x 10(-4) mol L-1, respectively. The methods have an excellent sample throughput of 30 samples h(-1) (method A) and 7 samples h(-1) (method B) with the sensitivity determined to be 1.1 x 10(-5) mol L-1 (method A) and 8.9 x 10(-6) mol L-1 (method B) as well as the precision RSD  LT = 3.4% for both methods. Some aspects of the possible mechanism of UA action on the BL oscillating and Duschman non-oscillating reaction systems are discussed in detail.

AB  - By numerically simulating the Bray-Liebhafsky (BL) reaction (the hydrogen peroxide decomposition in the presence of hydrogen and iodate ions) in a continuously fed well stirred tank reactor (CSTR), we find "structured" types of chaos emerging in regular order with respect to flow rate as the control parameter. These chaotic "structures" appear between each two successive periodic states, and have forms and evolution resembling to the neighboring periodic dynamics. More precisely, in the transition from period-doubling route to chaos to the arising periodic mixture of different mixed-mode oscillations, we are able to recognize and qualitatively and quantitatively distinguish the sequence of "period-doubling" chaos and chaos consisted of mixed-mode oscillations (the "mixed-mode structured" chaos), both appearing in regular order between succeeding periodic states. Additionally, between these types of chaos, the chaos without such recognizable "structures" ("unstructured" chaos) is also distinguished. Furthermore, all transitions between two successive periodic states are realized through bifurcation of chaotic states. This scenario is a universal feature throughout the whole mixed-mode region, as well as throughout other mixed-mode regions obtained under different initial conditions.

AB  - The non-periodic, periodic and chaotic regimes in the Bray-Liebhafsky (BL) oscillatory reaction observed in a continuously fed well stirred tank reactor (CSTR) under isothermal conditions at various inflow concentrations of the sulfuric acid were experimentally studied. In each series (at any fixed temperature), termination of oscillatory behavior via saddle loop infinite period bifurcation (SNIPER) as well as some kind of the Andronov-Hopf bifurcation is presented. In addition, it was found that an increase of temperature, in different series of experiments resulted in the shift of bifurcation point towards higher values of sulfuric acid concentration.

AB  - The Bray-Liebhafsky (BL) oscillatory reaction generated in the batch reactor at 62- 68 oC was perturbed by cobalt(II)-nitrate, supported on the macroreticular copolymer of poly-4-vinylpyridine with divinylbenzene (Co-PVPDVB). The kinetic data was analyzed of the complex pathways of the hydrogen peroxide decomposition in the examined BL reaction. The obtained results confirm that the kinetics of the BL reaction in the presence Co-PVPDVB comes partially from the Co-catalyst and partially from the macroreticular copolymer support.

Analizirani su kinetički podaci kompleksnih reakcionih puteva razlaganja vodonikperoksida u ispitivanoj BL reakciji.
