AB  - In this paper, 12-tungstenphosphoric acid (PWA) was synthesized in combination with FeCl3 at room temperature (25 oC). At such manner, Fe3+ ion exchange gave new 12-tungstenphosphoric salt of the transition metal iron (FePW12O40×nH2O; Fe-PWA). Thermal analysis determined the temperature of about 596 oC of the phase transition, i.e., the temperature at which the structure of the Kegin anion is disturbed. Therefore, it was chosen temperature above the breakdown of the Kegin anion of 650 oC, and which is required to obtain phosphate tungsten bronzes (PWB) doped with iron (Fe-PWB). The sample was kept in the oven for 10 minutes. Such obtained new Fe-PWB doped bronze was further investigated by the X-ray powder diffraction (XRPD) and Rietveld methods. The XRPD patterns of Fe-PWA and Fe-PWB were taken in the 3-90o 2θ angle range, and clearly reveal crystallographic and structural differences between these two phases. Determined unit-cell parameters of Fe-PWB obtained by the Rietveld method in the monoclinic crystallographic system are as following: a0 = 7.53(2) Å; b0 = 7.51(1) Å; c0 = 7.64(1) Å; β0 = 89.7(2)o; and V0 = 431(2) Å3. These unit-cell parameters were compared with PWB, as well as other previously doped bronzes (Li-PWB and Ca-PWB). It can be concluded that inserting of the Fe3+ ion into the PWB’s structure was undoubtedly proven, and have the most influence to the axis a0 (i.e., it significantly increased), angle β0 (i.e., it significantly decreased), and volume V0 (i.e., it significantly increased). On the other hand, influence to the axis c0 is quite smaller (i.e., it slightly decreased), whereas influence to the axis b0 is minor. Such behavior is also very different in comparison to the Li-PWB and Ca-PWB.

AB  - In this work, synthesized 12-tungstenphosphoric acid (H3PW12O40 × nH2O; PWA) was further ionically exchanged with Fe3+ ions, which led to the formation of the 12-tungstophosporic acid iron salt, (FePW12O40 × nH2O; Fe-PWA). Fe-PWA was then subjected to thermal analysis (TGA/DTA), determining the phase transition temperature of 576 °C from Fe-PWA to its corresponding phosphate tungsten bronze doped with iron, Fe-PWB. Using the X-ray powder diffraction (XRPD), Fourier-transform infrared spectroscopy (FTIR), and Scanning electron microscopy with an energy dispersive X-ray spectroscopy (SEM-EDS) method, the obtained Fe-PWA and Fe-PWB were additionally characterized, and compared. Due to channels and cavities in their structures, Fe-PWA and Fe-PWB were next examined as electrode materials for aqueous rechargeable batteries. Electrochemical measurements were done in aqueous solutions of 6 M LiNO3 by cyclic voltammetry. Fe-PWA and Fe-PWB exhibit different redox processes, which are discussed thoroughly in this work. Electrochemical results are showing that within the Fe-PWA structure, more Li+ ions can be intercalated in the first discharge cycle, but consecutive cycling leads to a fast capacity fade. While the Fe-PWB redox process was stable during cycling, its specific capacity is limited by the material's poor electrical conductivity. Improvements in Fe-PWB conductivity must be addressed in future studies in order to boost material’s electrochemical performance.

AB  - Cobalt molybdate is of importantce for the development of mobile telecommunication systems, such as mobile phones and high-quality microwave dielectric ceramics for high resonant frequency selectivity in microwave devices. Due to their special catalytic properties, cobalt molybdates have been used as catalysts in many chemical and petrochemical processes. The CoMoO4 nanoparticles ware synthetized in a simple, quick, and inexpensive way, by using a glycine nitrate procedure (GNP), with and without calcination at 450 °C [1], and investigated by applying the Briggs-Rauscher oscillatory reaction method [2]. The complex oscillatory BR reaction is sensitive to different insoluble analyte addition [3]. This feature of BR oscillatory reaction is used to investigate effect of different masses of GNP synthetized (with and without calcination at 450 °C) CoMoO4 samples on oscillatory dynamics. These two samples give the complete different effects in BR reaction. Obtained results strongly suggest that BR oscillatory reaction could be used for distinguishing these two samples, opening new direction in the investigation of ceramics materials.

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  - Thermal monitoring of a Briggs-Rauscher oscillatory reaction with a phase transition or  the state I (low concentration of iodide and iodine) to the state II (high concentration of  iodide and iodine) transition with formation of new solid iodine phase is presented. This  is the very first time that an oscillatory reaction and the state I to state II transition have  been monitored using a thermal camera. It should be pointed out, that the BR reaction  solution is not homogenized by stirring, and that only oxygen production influence the  solution mixing. Therefore, the analysis was done at three sampling points on the cuvette  where temperature change over time was observed, and compared with average  temperature distribution. The first point is chosen to correspond to the top of the solution  in the cuvette, followed by one in the middle of the volume and one at the very bottom of  the cuvette. Although the state I to the state II transition itself is not reproducible  (investigated transition exhibits crazy clock behavior), the overall temperature pattern has shown a reproducible character.

AB  - Due to Li-ion batteries having become the main power source of most portable electronic devices, their waste has also become a significant environmental problem. To find batteries that would be environmentally friendly, this work examines Zn-ion batteries in an aqueous solution of ZnCl2. The ZnMnO4 was synthesized by glycine nitrate combustion of Zn(NO3)2, Mn(NO3)2 and glycine as a chelating agent [1]. The structure of the material obtained was characterized by X-ray powder diffraction (XRPD) showing a spinel structure; the morphology was characterized by scanning
electron microscopy (SEM) showing that nano-particles were obtained. The electrochemical characterization was done by cyclic voltammetry in an aqueous solution of ZnCl2. The mixture pasted on the glossy carbon electrode was prepared by mixing the cathode material, graphite and polyvinyl diene difluoride (PVDF) in a ratio 85:10:5 [2]. Due to the low discharge capacity obtained of ~14 mAh g-1 for 5 mV s-1 , further examination was done by adding 1 ml of 1M Mn(NO3)2 into 10ml of a saturated aqueous solution of ZnCl2. After adding the Mn(NO3)2 , the discharge
capacity increased from ~14 mAh g-1 to ~65 mAh g-1 at the same polarization rate, making this additive a promising one for aqueous Zn-ion batteries. Further investigation needs to be directed to adding the same additive in larger amounts compared to 1ml to the same volume of the electrolyte. The results obtained suggest the aqueous Zn-ion battery described in this work to be a potentially promising “green” battery that may replace harmful commercial organic Li-ion batteries.

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  - Recently, two different effects of phosphate tungsten (PWB) and phosphate molybdenum (PMoB) bronzes (obtained by thermal treatment), on oscillatory Briggs-Rauscher (BR) dynamic have been found [1]. Although both are insoluble in BR solution [2], the addition of different masses of PWB linearly decreases the BR oscillation time, while the addition of different masses of PMoB had no effects on the BR reaction. Furthermore, PWB has an identical role as metal catalyst Mn2+ in
BR reaction and for obtained behavior is probably responsible the different mechanisms of heterogeneous catalysis of these bronzes in oscillatory reaction. Therefore, a deeper investigation was done in order to find the major structural characteristic of these two bronzes by using the XRPD method. What is so different for these two bronzes, causing dissimilar effects in BR
reaction, is it “just” catalytic activity of central cation or there is something more? The XRPD method confirmed very different structures of PWB and PMoB as monoclinic and orthorhombic, respectively [3,4]. This work tries to connect the structural properties of PWB and PMoB with BR oscillatory reaction responses, expanding the usage of oscillatory reaction in material science and catalysis, in general.

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  - Modifying commercial Li-ion batteries to become more environmentally friendly is of a growing concern. This paper provides an
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  - Modifying commercial Li-ion batteries to become more environmentally friendly is of a growing concern. This paper provides anexamination of a potential replacement for commercial cathode material using a naturally occurring purpurin in aqueous solutions oflithium 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 aqueoussolution of LiNO3 are approximately 40 mAh g−1. Compared to the capacity of ∼35 mAh g−1 obtained for commercially usedtransition 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 ofpurpurin 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  - Purpurin je organska boja dobijena kao ekstrakt iz biljke Maddre ubrane na planini Kopaonik. U ovom radu, purpurin je koritšćn kao potencijalna zamena za katodni materijal koji se koristi u komercijalnim Li-jonskim baterijama, baziran na neorganskim komponentama kao što su Co, Ni, Mn i Fe. U poredenju sa navedenim neorganskim supstancama, purpurin je potpuno prirodna organska boja koja ne zagaduje životnu sredinu. Organski rastvarč koji se obično koristi u Li jonskim baterijama je toksičan i zapaljiv, tako da je jedna od ideja ovog rada bila da se ispita ponašanje purpurina u vodenom elektolitu. Pošto je Li slabo rasprostranjen u rudama i teško se dobija, to je time i njegova cena viša, ekperiment je rađen u vodenom rastvoru NaNO3 ne bi li se ispitala zamena Li ekonomičnijim Na. Strukturna odredivanja purpurina vršena su IC-om, dok su elektrohemijska merenja vrtena cikličnom voltametrijom. Dobijeni rezultati pokazuju da vodeni rastvor NaNO3 nije pogodan rastvarč kada je u pitanju vrednost i stabilnost kapaciteta.
