AB  - Due to the interesting and potentially useful properties, phosphate tungsten bronzes are constantly being studied and attract a lot of attention. In the present work, two different metallic elements, belonging to the group of rare-earth metals, cerium and praseodymium, were used as a dopants for phosphate tungsten bronzes. Novel cerium and praseodymium doped phosphate tungsten bronzes were successfully synthesized and further characterized by thermal analyses, Fourier-transform infrared spectroscopy, X-ray powder diffraction, scanning electron microscopy
with energy-dispersive X-ray spectrometer and photoluminescence spectroscopy. The behavior of
cerium and praseodymium doped phosphate tungsten bronzes were examined in the Briggs-Rauscher oscillatory reaction. The changes in the oscillatory dynamics, caused by the addition of cerium doped and praseodymium doped phosphate tungsten bronzes, are used for distinction of these bronzes and also as a method for testing the catalytic features of the bronzes. Beside the nonlinear behavior, the bronzes have shown photoluminescence in the visible region (blue region).

AB  - The Briggs-Rauscher oscillatory reaction, which represents the oxidation of malonic acid in 
the presence of hydrogen peroxide and potassium iodate catalyzed by manganese ion in an 
acidic environment, proved to be extremely sensitive for testing insoluble materials, such as 
bronzes and clays. It was shown that origin of bentonite has high impact on the length of the 
oscillation time. In this work, the influence of different sizes of bentonite particles from the 
Bogovina deposit on the Briggs-Rauscer oscillatory reaction in the conditions of a closed 
reactor was investigated. Five particle sizes of bentonite, (< 25 µm, < 50 µm, < 75 µm, < 150 
µm and < 300 µm) having identical mass of 0.15 g, were tested. The addition of different 
particle sizes of Bogovina clay does not significantly influence the basic BR oscillogram.

AB  - It is well known that almost all living or biological systems are naturally in the oscillatory dynamic states and can be considered as biochemical reaction systems. These oscillatory dynamic states can be caused by internal self-organized phenomena, but also by external periodic variations of temperature, light, food, or seasonal changes. The hypothalamic-pituitary-thyroid (HPT) axis is one such nonlinear system with feedback that is always in an oscillatory dynamic state and L-tyrosine is its main representative.
The biological importance of L-tyrosine interactions with iodine species was the motivation for modelling of the oscillatory dynamics in the Bray-Liebhafsky (BL) reaction perturbed by L- tyrosine. Also, direct experimental investigation of metabolic processes in the human body is extremely complex to be done, and therefore any alternative approach is of great importance. Therefore, the BL reaction has the potential to be used as a model of the biological system due to certain characteristics shared with the considered processes; it is characterized by its oscillatory dynamics and based on the chemistry of hydrogen peroxide and iodine compounds commonly present in the thyroid gland, where L-tyrosine is iodinated.
The impact of L-tyrosine on the dynamics of the Bray-Lienbhafsky oscillatory reaction was investigated numerically using the proposed model. The study was focused on the examination of the sensitivity of the BL reaction to L-tyrosine perturbation. The obtained results indicated possible pathways of influence

AB  - In the past two decades, chemical oscillators have emerged as a popular tool for the determination of “reactive” analytes due to their great sensitivity toward any kind of external perturbations. They have found application in many fields of applied science enabling relatively easy quantitative and qualitative analyses. In this study influence of pyrocatechol, an important precursor in many organic syntheses, on the pre-oscillatory period of the Bray-Liebhafsky (BL) reaction was examined. The BL reaction was followed by the potentiometric method. In a series of experiments (in a concentration range from 1.5 × 10-5 M to 3 × 10-5 M), pyrocatechol was added 45 minutes after the start of the reaction, causing an immediate appearance of oscillations. For these experimental conditions, the period between the first and second oscillation increases linearly with the added pyrocatechol concentration. The obtained results can be useful for analytical purposes and accordingly, potential determination of unknown pyrocatechol concentration.

AB  - The transition from state I ( characterized by low iodide and iodine concentration) to state II (high iodide and iodine concentration) occurs in a nonlinear Briggs-Rauscher (BR) oscillatory reaction. This transition was studied by two methods: potentiometric and holographic. The first derivative technique was applied to the obtained electrochemical and holographic curves of the transition state I→state II to obtain the corresponding slopes. Based on these slopes, the results of the two methods are compared. The obtained holographic slope for the transition from state I to state II is higher than the potentiometric one in all selected reaction sections. In the initial phase of the transition from state I to state II, it is clear that the velocity of the holographic method is twice that of the potentiometric method. While this trend shows a twofold increase at the beginning of the phase transition, it deviates in the other phases, where the holographic measurements show a 1.5-fold higher rate in the middle. The obtained results could have a strong impact on the study of nonlinear systems in the future.

AB  - The organic pigments offer promising opportunities for developing new sustainable electrode materials for lithium batteries. Some of them have been identified as cathode material with very encouraging reversible lithium ion storage characteristics. One of them is a naturally occurring purpurin extracted from the Madder plant (Rubia tinctorum) for which we confirmed this good electrochemical behavior by cyclic voltammetry. One of the strategies towards obtaining materials with even better characteristics is a structural modification of already existing pigments. Building a theoretical model that could predict the redox properties of these new compounds can be very useful towards achieving that goal. In order to build a 3D QSAR (quantitative structure–activity relationship) model for material redox potential prediction, 9 organic pigments with known redox potentials were extracted from the literature. Based on molecular interaction field (MIF) probes we calculated standard GRIND (grid-independent) descriptors and constructed following principal PLS (partial least squares) model. By validation with the literature data, but also with the obtained experimental data for purpurin, this model proved very reliable in predicting the redox potential. A comparison was also made with the machine learning model that was formed in parallel.

AB  - A non-equilibrium process, i.e., the state I (low concentration of iodide and iodine) to the state II (high concentration of iodide and iodine) transition, occurring after oscillatory Briggs-Rauscher reaction, was monitored by fast camera. The experiment's goal was not only to monitor the release of oxygen and the phase transition but also to use patterns formed by oxygen bubbles to get new insight into the kinetics of the process and the formation of solid iodine. To the best of our knowledge, it is the first time that an oxygen bubble pattern obtained by a fast camera has been used to analyze oscillatory system dynamics.

AB  - The oscillatory Briggs-Rauscher (BR) reaction was applied on solid insoluble materials -
bentonite clays from different deposits: Wyoming (Swy-2), Texas (STx-1b), Idaho (SbId-1), 
Arizona (SAz-2), Bogovina and Mečji Do, last two from Serbia. Under the same BR 
experimental conditions, the addition of identical masses (0.25 g) of particular clay resulted in 
different effects on oscillatory dynamics. There is a prolongation, quenching, or no influence 
on oscillatory dynamics. Additionally, in the case of different masses of clay added, the 
response of the BR oscillating system resulted in a complex behavior pattern (oscillatory 
period vs. bentonite mass). This complex behavior pattern (firstly obtained by using clays in 
BR), could be applied as a fingerprint for bentonite identification. It is supported by facts that 
montmorillonite/beidellite ratio, cation exchange capacity, principal exchange cation, the 
extent of iron leaching in the acidic environment of BR reaction, and specific surface area of 
each used clays were not exclusively responsible for observed behavior in oscillatory 
reaction. This means that all bentonite’s properties combined are probably responsible for 
behavior obtained in oscillatory reaction, making BR reaction as an easily available and 
economical method for the identification of bentonite clay origin

AB  - Indigo carmine is a commonly used industrial blue dye. To determine its concentration in a commercially available food dye composed of a mixture of indigo carmine and D-glucose, this paper characterizes it through (ATR, KBr) FTIR micro-Raman as well as UV/Vis and clock: Briggs–Rauscher (BR) oscillatory reaction methods. The indigo carmine was detected in the bulk food dye only by applying micro-Raman spectroscopy, indicating a low percentage of the indigo carmine present. This research provides an improvement in the deviations from the experimental Raman spectrum as calculated by the B97D/cc-pVTZ level of theory one, resulting in a better geometrical optimization of the indigo carmine molecule compared to data within the literature. The analytical curves used to determine indigo carmine concentrations (and quantities) in an aqueous solution of food dye were applied by means of UV/Vis and BR methods. BR yielded significantly better analytical parameters: 100 times lower LOD and LOQ compared to commonly used UV/Vis. The remarkable sensitivity of the BR reaction towards indigo carmine suggests that not only does indigo carmine react in an oscillatory reaction but also its decomposition products, meaning that the multiple oxidation reactions have an important role in the BR’s indigo carmine mechanism. The novelty of this research is the investigation of indigo carmine using a clock BR reaction, opening new possibilities to determine indigo carmine in other complex samples (pharmaceutical, food, etc.).

AB  - The Briggs-Rauscher (BR) reaction is an oscillating reaction in which the oxidation of malonic acid (CH2(COOH)2) in the presence of hydrogen peroxide (H2O2) and potassium iodate (KIO3) is catalyzed with a metal ion (usually Mn2+) in acidic aqueous solution. The BR reaction is very sensitive to the addition of different types of analytes. Every change in oscillatory dynamics, caused by analyte addition, can be used for the appraisal of analyte concentration, as well as its potential antiradical or catalytic activity. The cerium doped phosphate tungsten bronze (Ce-PWB) was obtained by thermal treatment and characterized by TGA, DSC, FTIR, and XRPD technics. In this work, the behavior of Ce-PWB and its influence on BR oscillatory dynamics was examined. The results revealed that an increase in the mass of added Ce-PWB has slightly shortened the oscillation time duration with the minimal change in the form of the basic BR oscillogram, suggesting the catalytic effect of this bronze in oscillatory reaction

AB  - For the preparation of praseodymium doped phosphate tungsten bronze (Pr-PWB), as a
starting material is used 12-tungstophosphoric heteropoly acid H3PW12O40×29H2O
(PWA) [1]. PWA was first converted into H3PW12O40×6H2O (6-PWA) by heating it to
80 °C in a kiln. The aqueous PrCl3×H2O solution was prepared by dissolving 0.7102 g
of PrCl3×H2O in distilled water. This solution is then mixed with aqueous solution of 6-
PWA, slightly heated in order to start the crystallization process and left overnight to
finish the crystallization. The produced greenish crystals of praseodymium doped
phosphate tungsten bronze are created by heating the obtained salt PrPW12O40×nH2O in
a furnace from room temperature to 600 °C. The conditions for thermal phase
transformation of praseodymium salt of 12-tungstophosphoric heteropoly acid to
produce new praseodymium phosphate tungsten bronze, have been investigated in the
current work. The new material (Pr-PWB), synthesized from Keggin's anion structure as
a precursor, is successfully formed. The potential practical application of Pr-PWB is in
its installation in batteries and fuel cells, as a catalyst, and due to its specific green color

abstract = "For the preparation of praseodymium doped phosphate tungsten bronze (Pr-PWB), as a
starting material is used 12-tungstophosphoric heteropoly acid H3PW12O40×29H2O
(PWA) [1]. PWA was first converted into H3PW12O40×6H2O (6-PWA) by heating it to
80 °C in a kiln. The aqueous PrCl3×H2O solution was prepared by dissolving 0.7102 g
of PrCl3×H2O in distilled water. This solution is then mixed with aqueous solution of 6-
PWA, slightly heated in order to start the crystallization process and left overnight to
finish the crystallization. The produced greenish crystals of praseodymium doped
phosphate tungsten bronze are created by heating the obtained salt PrPW12O40×nH2O in
a furnace from room temperature to 600 °C. The conditions for thermal phase
transformation of praseodymium salt of 12-tungstophosphoric heteropoly acid to
produce new praseodymium phosphate tungsten bronze, have been investigated in the
current work. The new material (Pr-PWB), synthesized from Keggin's anion structure as
a precursor, is successfully formed. The potential practical application of Pr-PWB is in
its installation in batteries and fuel cells, as a catalyst, and due to its specific green color
it could also be used as a pigment.",

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  - Indigo carmine (InC) is broadly used blue dye in different industrial area. This work aims to obtain analytical curves for determination of InC in aqueous solutions. For such as purposes, two methods were used: UV/VIS spectrophotometry and the kinetic method based on Briggs- Rauscher (BR) oscillatory reaction, and compared in terms of methods sensitivity which expressed as limit of detection (LOD) and limit of quantification (LOQ). To the best authors' knowledge, as candidate for proposed analytical method, the BR oscillatory reaction was applied for the first time to InC quantification. The results obtained show that kinetic method using BR oscillatory reaction has a quite lower LOD and LOQ making this method more acceptable to determine an unknown concentration of InC dissolved in water, compared to UV/Vis spectrophotometric method.

AB  - Over the last few decades, heavy metal pollution has become an issue of great interest, primarily because of the potential human health risks. Contamination of seawater with heavy metals, and thus of marine species, is a direct consequence of urban and industrial pollution. Therefore, two fish samples Sardina pilchardus (S. pilchardus) collected from the Boka Kotorska Bay and the coastal part of the open sea on the Montenegrin coast were compared in terms of heavy metals: lead, mercury, copper and zinc concentration. Results show that metal concentrations in S. pilchardus samples in both sampling areas were lower than the maximum permitted concentrations defined by national and European legislation in fisheries and fish muscle tissue, meaning S. pilchardus obtained from the Boka Kotorska Bay and the coastal part of the open Adriatic Sea safe for human nutrition.

AB  - Ultraviolet (UV)–visible (Vis) spectroscopy is widely used in all modern laboratories as a routine method of analysis. The monitoring of chemical reactions in an aqueous solution involving a gas product is a demanding task but particularly for oscillatory reactions which are obtainable in a narrow concentration range. In this work, the optimization of experimental conditions for UV–Vis measurements of the Bray–Liebhafsky (BL) oscillatory reaction producing oxygen was done by using an internal standard. After applying the method of the internal standard on iodine absorbance at 460 nm, the characteristic BL oscillatory parameters (and iodine changes) are clearly evident. The obtained results allow students to apply their existing knowledge and, through a simple experimental setup, understand the importance of the internal standard, but at the same time, they show how they can solve the problem of UV–Vis noise during the time-based measurements of reactions involving gas products in general.

examination of a potential replacement for commercial cathode material using a naturally occurring purpurin in aqueous solutions of
lithium and sodium salts. The purpurin is extracted from the Madder plant (Rubia tinctorum) and characterized through XRPD, FTIR,
and SEM methods. The intercalation and de-intercalation capacities obtained for the purpurin as a cathode material in the aqueous
solution of LiNO3 are approximately 40 mAh g−1. Compared to the capacity of ∼35 mAh g−1 obtained for commercially used
transition metal oxides in an aqueous solution of Li salt, results presented make the purpurin a promising material for the “green”
development of Li-ion batteries. Although the initial purpurin capacity in NaNO3 solution is almost doubled (∼73 mA h g−1)
compared to that of Li-salt, it is unstable and fades during cycling. The possible explanation of the electrochemical behavior of
purpurin as the cathode material in aqueous solutions of Li and Na salts is discussed in detail.

AB  - Indigo carmine (E132) is an organic dye used in the food, pharmaceutical, and cosmetics industries. It is commonly applied as a dye for food coloring in combination with d-glucose. Since this dye may be harmful, especially for children, this research aims to obtain an analytical curve by a UV/Vis spectroscopy to determine the unknown concentrations of indigo carmine in different samples. Additionally, the concentration of E132 was determined in a sample of hard candy, menthol strong, PIONIR. According to the maximum recommended intake of E132 being 0.5 g per kg, the obtained results suggest that consuming this candy is safe for children.

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 oscillatory Briggs‐Rauscher (BR) reaction was applied on solid insoluble materials i. e. bentonite clays. Under the same BR experimental conditions, the addition of identical masses of bentonite of different origin resulted in different effects on oscillatory time duration (τ): no influence, quenching, or prolongation. It was found that the following bentonite properties: montmorillonite/beidellite ratio; cation exchange capacity; principal exchange cation; extent of iron leaching in acidic environment of BR reaction; and specific surface area of clay were not exclusively responsible for observed behavior. On the other hand, the influence of added mass, for all investigated clays, resulted in the same behavior pattern. The increase of the mass of added clay increased τ up to the certain maximal value (τmax, mmax) characteristic for each clay. Further increase of mass resulted in quenching. Therefore, (τmax, mmax) pair can be regarded as the “fingerprint” characteristic of bentonite useful for identification of its origin. Furthermore, the addition of naturally occurring and non‐toxic clay in an oscillatory reaction can offer a versatile approach to tune the oscillation dynamics of nonlinear chemical systems.

AB  - The pyrocatechol inhibitory effect on the oscillatory Bray-Liebhafsky (BL) reaction is reported. Obtained results are compared with those available in the literature (R. Cervellati et al, Helvetica Chimica Acta 2001) for Briggs-Rauscher (BR) reaction with pyrocatechol addition. The two orders of magnitude larger calibration curve slope obtained in BR in comparison to BL reaction, suggests that different reactions are responsible for inhibitory effects in these systems. The potential explanation of pyrocatechol behavior is given by employing the ultraviolet-visible (UV/VIS) spectroscopy, density functional theory, and coupled cluster computational methods. The last two were employed for the first time to discover potential candidates among unstable chemical species HIO, HIO2, I2O, HOO•, HO•, IO•, IO2•, and I• of the BL (and BR) system for reaction with pyrocatechol. The calculated reaction rate constants for the hydrogen atom transfer reactions between pyrocatechol and free radical intermediates indicate the following order of reactivity: HO• > IO• > HOO• > IO2•. The same order of reactivity is also observed in the case of a thermodynamic investigation. In addition, kinetic insight indicates that the inhibitory behavior of pyrocatechol could not be explained with one particular chemical reaction in the BL (or in the BR) oscillatory system.
