AB  - Five celestine crystals are sampled from the (paleo)surface intervening between the late Miocene to Pleistocene basaltic sequences of the Jabal Eghei(Nuqay) volcanic province (southern Libya). The celestine specimens are characterized by applying the combination of the SEM-WDS, ICP/OES, XRPD, and IR methods. The celestine minerals are further analyzed for their color variations and minerogenetic framework. Three samples have greenish-blue-to-blue (480.4-482.5 nm), whereas the other two samples have blue-green color (cyan; 489.1-494.1 nm). The color purity ranges from 1.36-7.16. Their similarity of chemical content is fitting into the celestine near-end members, in which exclusively 1.6-4.1 at. % of Sr2+ content was substituted by Pb2+ (0.7-0.9 at. %), Ba2+ (0.5-0.7 at. %) and Ca2+ (0.2-0.8 at. %). The composition includes vacancies ranging from 1.0 to 1.9 at. % (observed only in three samples). The content of other chemical elements is minor. The resulting unit-cell parameters have the following ranges: a0=8.3578(9)-8.3705(6) Å; b0=5.3510(5)-5.3568(4) Å; c0=6.8683(7)-6.8767(2) Å and V0=307.17(5)-308.34(4) Å3. The XRPD and IR results are mainly in accordance with the SEM-WDS results, having a higher level of correlativity. However, the analysis exposed a few discrepancies yielding several possible interpretations. The illustrated discrepancies were primarily caused by a slight unit-cell axial anisotropy i.e., thermal expansion. In this manner, the results yield a new geothermometric tool that is based on the unit-cell axial anisotropy. The investigated Sr-bearing celestines were formed during a Miocene intraplate volcanism, basaltic magmas, and associated brines lifted by the structural conduits (normal faults crosscutting the Sirt basin). The Sr-bearing fluids were then poured into and over the faulted and fractured lagoon-type gypsum, anhydrite Eocene sediments. The celestine minerals were produced within a ~ 368-430K (~ 95-157 oC) temperature range. The celestine is formed at slightly elevated temperature and pressure conditions, close to the shallow subsurface environment (over 250 bars).

AB  - In this paper we provide the observations of a group of toxic elements Cu, Pb, Cr, Co, Ni, Pb, V, Zn, Sb, and Mo, in the soils that are sampled at the distances of 1 m and 5 m (two layers) from the road (Highway 75, north section). The observation of toxic elements are indicating a level of the existing contamination, availability and ecological risk. The mean values of the content of the elements Cr, Cu, Mo, Pb, Sb and Zn are lower with respect to the reference MAC values, whereas the mean and particular values of the content of Co, V, and Ni are higher. The content of the Sb, Pb, Мo, Cr, Cu, V and Zn reach higher values in the surface layer near to the road – at a distance of 5 m. The particular values of Pb, Zn and Cu only in the surface samples, at both distances, at two sampling localities, are indicating the presence of anomaly. However, the results of the content of the elements in most mobile forms are suggesting a presence of insignificant content of the toxic elements, which can easily become available to the environment and spread by streams or groundwater. The results of the Risk assessment code (RAC) confirms that there is a lower risk of contamination of the near-road environment by these toxic elements.

AB  - The grossular garnet from rodingite-type rock from the Suva Česma area in western Serbia is characterized with its weak anisotropic nature. Because its anisotropy could indicate a non-cubic lower symmetry, SEM-EDS and Rietveld powder refinement methods were used. The SEM-EDS results have shown that the garnet has a (Ca3.00Mn0.01)3.01(Al1.82Fe0.15Ti0.02)1.99(Si2.97Al0.03)3.00O12 chemical composition (i.e., Grs91Adr08), which can be more specifically explained as ferric iron containing grossular. The next step further used Rietveld powder refinements of the various crystal structures in the Ia‾3d, R‾3c, R‾3, I41/a, Fddd, C2/c, and I‾1 space groups as well as a single mixture, which was followed by a comparative analysis of the R-values, site occupancy factors, and bond lengths and angles. The synthesis of these results showed both that the studied grossular garnet is not cubic and that it crystallized in the disordered Fddd space group with the final RB = 5.29% and RF = 1.75%. It was presumed that the grossular formed at temperatures between 150 and ~600 °C.

The SEM-EDS results have shown that the garnet has a (Ca3.00Mn0.01)3.01(Al1.82Fe0.15Ti0.02)1.99(Si2.97Al0.03)3.00O12 chemical composition (i.e., Grs91Adr08), which can be more specifically explained as ferric iron containing grossular. The next step further used Rietveld powder refinements of the various crystal structures in the Ia‾3d, R‾3c, R‾3, I41/a, Fddd, C2/c, and I‾1 space groups as well as a single mixture, which was followed by a comparative analysis of the R-values, site occupancy factors, and bond lengths and angles. The synthesis of these results showed both that the studied grossular garnet is not cubic and that it crystallized in the disordered Fddd space group with the final RB = 5.29% and RF = 1.75%. It was presumed that the grossular formed at temperatures between 150 and ~600 °C.",

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  - 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  - In this work, synthesized 12-tungstenphosphoric acid (H3PW12O40 ∙ nH2O, PWA) was further
ionically exchanged with Fe3+ ions, which led to the formation of the FePWA salt (FePW12O40 x nH2O). FePWA was then subjected to thermal analysis (TGA/DTA), which determined the phase transition temperature ( i.e., when the Keggin anion collapses). The temperature of collapsing the Keggin anion is about 600 °C, at which phosphate tungsten bronzes doped with iron (FePWB) are obtained. Obtained FePWB was further characterized by XRPD and FTIR, which confirmed the formation of the desired structure. FePWA and FePWB were examined as an electrode material for aqueous rechargeable batteries due to the channels and cavities present in their structure. Experiments were done in aqueous solutions of 6 M LiNO3 by cyclic voltammetry. The differences in the redox processes of heteropoly acid salts and iron-doped bronze were discussed thoroughly and correlated with the XRPD and FTIR results. The catalytic activity is also investigated by Briggs-Rauscher method followed potentiometricaly.

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  - Phosphate tungsten bronzes (PWBs) constantly attract a lot of attention due to their
interesting chemical, electrical, optical, and mechanical features [1]. Heteropoly acid
hydrate H3PW12O40×29H2O (PWA) was obtained by dissolving Na2WO4×2H2O in a
H3PO4-HCl mixture and by extracting the precipitate with ether at room temperature.
The dehydration process of H3PW12O40×29H2O (PWA) to H3PW12O40×6H2O (6-
PWA) is done by heating of PWA in a kiln at 80 °C. An aqueous solution of
H3PW12O40×6H2O is then mixed with an aqueous solution of CoCl2×6H2O, gently
heated to initiate the crystallization process, and left overnight to complete
crystallization. The obtained with (CoHPW12O40×nH2O, CoPWA) is then heated in a
furnace, from room temperature to 600 °C, during which cobalt phosphate tungsten
bronze crystals are formed. Obtained CoPWB was further characterized by FTIR, XRPD
and SEM-EDS methods which confirmed the formation of the desired structure. In this
work, cobalt phosphate tungsten bronze was synthesized and characterized for the first
time in order to obtain more information about its structure, chemical characteristics and
potential practical application. A potential practical application of Co-PWB is in its
incorporation into aqueous lithium-ion batteries and catalysts in the Briggs Rauscher
reaction.

AB  - Regional tectonic synthesis suggests that a segment of the bipartite eastern Gondwana-type Carpathian-Balkan nappe-stacked Getic/Kučaj/Supragetic basement (eastern Serbia) experienced Cambro-Ordovician Cenerian (Sardic) accretionary-type deformation. The Ordovician basement of the Alpine Getic/Kučaj nappe exposes an earlier-mapped shallow-marine transgressive-type Fe-silicate-rich ironstone sequence. The Ordovician ironstone is used as second-order evidence of a hitherto untraceable tectonically-driven unconformity. Early Paleozoic compression is consistent with the controversial latest Cambrian to intra-Ordovician Cenerian (Sardic) interval, documented by (i) a 488 Ma metamorphic event and available detrital zircon data (Serbo-Macedonian gneissic unit), (ii) a deformed Lower Ordovician Getic/Kučaj brachiopod assembly, and (iii) an intra-Ordovician unconformity dividing the Supragetic basement/”Vlasina complex”. The data further
imply that mafic gabbro-dominating sills, cropping out in the northern Getic/Kučaj unit, are consistent with Ordovician back-arc activity. The Getic/Kučaj gabbro is Ordovician in age, piercing a Neoproterozoic–Cambrian (Lower Ordovician) Supragetic/”Vlasina complex”, overlain by a transgressive Silurian–Devonian sedimentary sequence. The emergence of Ordovician mafic intrusions reflects submarine volcanism, while deep-water redox conditions were capable of a sustained supply of Fe (similar to Sardinia). In terms of tectono-palaeogeographic reconstructions, the origin of Ordovician shortening and mafic volcanism is often challenged. The latter is broadly analogous with the embryonic eastern Rheic Ocean, corresponding additionally to the Armorican spur and related intra-continental magmatism.

AB  - The study represents the composition of minor elements, including rare earth elements (REE)
in six selected samples with a dominant alunite content (>50%), having a significant correlation between them. The content of the trace (As, Ba, Co, Cr, Cu, Ga, Ge, P, Li, Nb, Zn, Ni, Pb, V, Zr i Sr), and REE (lanthanides, Y, Sc and Th) elements, is characterized using by ICP / OES technique (Spectro Blue, Germany), after total fusion with NaKCO3 at 1000 °C. During the period 2009-2013., a geological study of alunite occurrence in the Lece-Radan area was performed. The mineralogical and chemical composition of major components of the samples is characterized in this phase (Tančić et al., 2021), as well as the composition of minerals within alunites group: Alunite (KAl3(SO4)2(OH)6, (27-52%), Natroalunite NaAl3(SO4)2(OH)6,(27-48 %), Schlossmacherite HAl3(SO4)2(OH)6 (5-46 %). Besides alunite mineral group, in these samples are detected dominant presence of Quartz (in five samples), Kaolinite (two samples) and Tridimite (one sample). By comparison of the mean and the single values of the trace elements with the reference - the continental core contents, we conclude that content of As, Pb, Ba, Sr and Li are with elevated values. The average content of La registered across of all samples used for this study, with exception of the one sample. This sample is characterized with the lowermost content of the most trace elements explored (with exception of the content of Ga). Most likely, such situation is a consequence of the formation of the alunite in this sample that is collected within the zone the highest temperature (see Tančić et al., 2021). The content of Ga and V, which exceed the reference values in other two samples as well, could indicate the enrichment of the alunite with these elements. This could be a result of the interaction of a hydrothermal fluid, formerly moving along or near a coal-bearing stratigraphic sequence. Indeed, the study area contains a number of organic-type carriers, including a documented presence of the Lower and Middle Miocene sediments, rich in organic matter (Čučalska sequence). In addition, the analyzed samples are enriched with the elements La, Ce, Nd (group of Light Rare Earth Elements - LREE), as well as Th and Sc. The significant correlation coefficient (r> 0.60) of the sum of LREE -ΣLREE contents with Al (r = 0.91) and with P (r = 0.65) may indicate that LREE, after hydrothermal alterations, have
entered into the alunite structure, characterized with a higher affinity than HREE (Heavy Rare Earth Elements). Additionally, higher value of the correlation coefficient ΣHREE with Zr (r = 0.70) and Sc (r = 0.69), can be explained by their lower mobility and higher affinity for refractory minerals, that are more resistant to further alterations (Ramos et al. 2016). A significant correlation between Nb-Th (r = 0.61), Nb-P (r = 0.91), Nb-Al (r = 0.60), Nb-ΣREE (r = 0.61), indicate its natural grouping with these elements that are present (Hawks and Webb, 1968) in the alunite structure itself. The content of Li is in the function of the alunite presence (%), associated with the Na- and H- alunite ( Natroalunite and Schlossmacherite, respectively (r = 0.85). Such correlativity indicates that during the mineral formation, K was rather exchanged by Li in the crystal structure of alunite.

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

abstract = "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.

AB  - Within the cooperation of the Geological Survey of Serbia (former Geoinstitute, Belgrade,
Serbia) with the Industrial Research Center (Tripoli, Libya), during the period from 2006 to 2010 many polymineral samples were obtained from central and southern parts of Libya whose exact mineral composition was unknown, and which were intended for analysis by X-ray diffraction method. With the X-ray diffraction method on powdered samples there were determined the presence of numerous mineral kinds, such as: quartz, gypsum, anhydrite, calcite, aragonite, halite, dolomite, celestine, bassanite, palygorskite, ankerite, thenardite, fluorite, hematite and goethite; as well as various mineral groups: clays (illite, kaolinite, montmorillonite), chlorites, micas, feldspars, serpentines, zeolites and amphiboles. In this paper, a more detailed crystallographic analysis of thenardite (Na2SO4) and ankerite [Ca(Fe2+,Mg)(CO3)2] was performed, given the fact that these minerals are quite rare in nature, as well as to indicate the possible way of their formation as marine evaporites. These minerals were identified as dominant in sample 1018/10/1 from southern Libya (Sheet Wādi Eghei, NF 34-1), along with secondary calcite, quartz, and clay minerals.
Calculated unit-cell dimensions of thenardite (space group Fddd, No 70) of: a0=9.820(3) Å; b0=12.312(3) Å; c0=5.867(1) Å; α=β=γ=90o; and V0=709.3(2) Å3 are in a very good agreement with the reference data (ICDD-PDF 74-2036: a0=9.829 Å; b0=12.302 Å; c0=5.868 Å; α=β=γ=90o; and V0=709.54 Å3).

Since ankerite is very similar to dolomite (space group R-3, No 148; ICDD-PDF 74-1687: a0=b0=4.815 Å; c0=16.119 Å; α=β=90o; γ=120o; and V0=323.64 Å3), significantly larger calculated unit-cell dimensions prove that there was a significant (over 60%) isomorphic exchange of smaller Mg 2+ ion with bigger Fe2+.

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
it could also be used as a pigment.

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  - The Lece-Radan area of the Oligo-Miocene magmatic complex (former Tethyan active margin, southern Serbia) contains more or less altered volcanic and/or pyroclastic rocks of predominant andesitic, andesitic-dacitic, to dacitic composition. Alteration seen at exposures varies in type and intensity. Samples with documented alunitization were collected from hydrothermally altered zones embedded within local geological units of Oligo-Miocene age. Mineralogical-chemical study has confirmed for the first time the presence of alunite group minerals (thirty-one occurrences) in this area. The minerals of the alunite group described exhibit different compositions that are remarkably consistent with both different alteration types and host lithologies. Six samples characterized in detail show the following solid solutions: Alu52Nal43Sch5, Alu48Nal40Sch12, Nal48Alu35Sch17, Nal44Alu35Sch21, Alu36Sch33Nal31 and Sch46Alu27Nal27 (Alu, Nal and Sch refer to alunite, natroalunite and schlossmacherite, respectively). The cross-cutting alunite-bearing fracture pattern and its density indicate a high-sulphidation epithermal palaeoenvironment. The alunite discovery is consistent with the structural setting (fracture frequency) emphasizing its dominant role in controlling the local mineralization.

AB  - The calcium phosphate tungsten bronze (Ca-PWB) has been synthesized and characterized (TGA, DSC, XRPD, FTIR, SEM). The influence of solid insoluble materials Ca-PWB, as well as lithium doped (Li-PWB) and cation free phosphate tungsten (PWB) bronzes on the oscillatory Briggs-Rauscher (BR) reaction dynamics, is compared. The results show that doping with Li and Ca reduces sensitivity of the BR reaction towards bronzes addition. These findings suggest the usage of the BR reaction as an innovative method for testing of different properties of bronze material. The behavior of PWB in the BR reaction is significantly changed with divalent cation (Ca2+) doping. The reasons for the different bronzes behavior were found in their calculated unit cell volumes. Namely, the compressed Ca-PWB unit cell volume indicates the difficult availability of the active site for heterogeneous catalysis. Hence, the linear correlation (slope) of the BR oscillogram’s length (τosc) vs. mass of bronze in BR reaction might be considered as a new parameter for the evaluation of the bronzes catalytic activity.
AB  - У овом раду синтетисана је и окарактерисана (TGA, DSC, XRPD, FTIR, SEM) нова калцијумом допирана фосфат волфрамова бронза (Ca-PWB). Испитан је и упоређен утицај фосфат волфрамове бронзе (PWB), литијумом допиране фосфат волфрамове бронзе (Li-PWB) и калцијумом допиране фосфат волфрамове бронзе (Ca-PWB) на осцилаторну динамику Briggs-Rauscher (БР) реакције. Резултати показују да допирање катјонима Li+ и Ca2+ смањује осетљивост БР реакције на додатак нерастворних бронзи, што се огледа у смањивању нагиба праве осцилаторног времена (τosc) БР реакције у функцији масе додате допиране бронзе. Добијени резултати сугеришу употребу БР реакције као иновативне методе за испитивање различитих својстава допираних и недопиране фосфат волфрамове бронзе. Разлози за различито понашање бронзи у осцилаторној реакцији пронађени су у различитим величинама јединичних ћелија PWB, Li-PWB и Ca-PWB. Наиме, најмања вредност, тј. сабијање јединичне ћелије допирањем калицијумом указује на тежу доступност активних места за хетерогену катализу. Каталитичка активност бронзи усмерена је ка реакцијама оксидације које укључују водоник-пероксид (један од реактаната БР реакције). Стога би се линеарна корелација (нагиб) τosc у функцији масе бронзе у БР реакцији могла сматрати новим параметром за процену каталитичке активности бронзе, али и других материјала.
