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  - Phosphate-tungsten bronzes (PWBs) constantly attract a lot of attention owing to their interesting chemical, mechanical, and optical properties. Furthermore, tungsten bronzes as inert inorganic solids, exhibit interesting and useful electronic properties when rare-earth ions are incorporated into their structure. Cerium doped phosphate-tungsten bronze (Ce-PWB) is obtained in the process of phase transformations of CePW12O40×6H2O (Ce-PWA) salt. The brown crystals of Ce-PWB are formed after heating of Ce-PWA in a furnace, in a temperature range from room temperature to 650 °C. In the present paper the luminescence properties of undoped PWB and Ce-PWB are analyzed and compared. Regarding the characterized luminescence properties of PWB and Ce-PWB, only PWB matrix showed luminescence, while dopant Ce3+ had no significant influence on the change of the emission spectra with characteristic spectra for this ion. The obtained CIE chromaticity diagrams showed that both samples emit in the deep blue region, suggesting their possible use as a blue emitting source for white light-emitting diodes (LEDs).

AB  - Nowadays phosphate tungsten bronzes (PWBs) attract a lot of attention due to their interesting chemical, mechanical, and optical features. Moreover, tungsten bronzes as inert inorganic solids, with incorporated rare-earth ions in their structure, show interesting and useful electronic properties. Praseodymium doped phosphate tungsten bronze (Pr-PWB) is obtained in the process of phase transformations of PrPW12O40∙6H2O (Pr-PWA) salt. The green crystals of Pr-PWB are formed after the heating of Pr-PWA in a furnace, in a temperature range from room temperature to 650 °C. In the present paper the fluorescent properties are analyzed of Pr-PWB, its precursor – 12-tungstophosphoric heteropoly acid, H3PW12O40∙29H2O (PWA) with Keggin's anion structure, as well as the intermediate – Pr-PWA salt. The luminescent properties where characterized and the 
obtained results showed that both samples emit in the deep blue region, indicating their potential use as a blue emitting source for white light LED's.

AB  - Phosphate tungsten bronzes (PWBs), due to their intriguing and potentially valuable properties, have consistently garnered research attention [1]. In this study, we introduced two rare-earth metallic elements, namely cerium and praseodymium, as dopants for PWBs. This led to the successful synthesis of novel PWBs doped with cerium and praseodymium, which were subsequently subjected to various characterization techniques, including thermal analyses (TA), Fourier-transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRPD), scanning electron microscopy with energy-dispersive X-ray spectrometry (SEM-EDX), and hotoluminescence spectroscopy (PL). The behavior of cerium and praseodymium doped phosphate tungsten bronzes (Ce-PWB and Pr-PWB) [2], was investigated in the Briggs-Rauscher (BR) oscillatory reaction. The 
alterations in the oscillatory dynamics, brought about by the incorporation of cerium and praseodymium dopants, served as a means to distinguish between these bronzes. Additionally, this approach provided a method for assessing the catalytic properties of the bronzes. Apart from their nonlinear behavior, these bronzes also exhibited photoluminescence in the visible spectrum, specifically in the blue region.

AB  - The material’s size and shape influence its physical, chemical and mechanical properties. This study describes an investigation of natural photonic structure of the butterfly’s wing, mainly composed of chitin. The effect of corrugations at the nanoscale on material’s optical response is unambiguously revealed in the presented thermal measurements. Furthermore, the presented study shows the possibility of exploiting holography to monitor dynamics in situ.

Ова студија описује проучавање природних фотонских структура, крила лептира која се претежно састоје од полимера хитина. Ефекат нано коругације на оптички одговор материјала је презентован кроз термална мерења. Такође је представљена могућност примене холографске методе за праћење динамике in situ.

AB  - The essential oil content in cumin samples from Serbian market ranged between 2.0 and 4.0%, with 22 identified compounds, among which the most abundant were cumin aldehyde, β-pinene, γ-terpinene, γ-terpinene-7-al and p-cymene. Postdistillation cumin seeds waste material that remained after the essential oil extraction contains total polyphenols of between 30.1 and 47.5 mg GAE/g dry extract, as estimated by the Folin-Ciocalteu method. Hydroxybenzoic and hydroxycinnamic acids, as well as glycosides of flavonones and flavonoles, are the dominant polyphenols. However, according to DPPH method, the antioxidative potential of cumin postdistillation seeds waste was poor and it ranged between 0.02 and 0.04 mM TE/g. Further research will be focused on agro-food implementation of postdistillation waste material of cumin and other plants which are used for the essential oil production.
AB  - Sadržaj etarskog ulja u plodovima kumina prisutnog na Srpskom tržištu kreće se između 2.0 i 4.0%. Primenom GC/MS identifikovane je ukupno 22 komponente u etarskim uljima kumina, među kojima su najzastupljenije: kumin aldehid, β-pinen, γ-terpinen, γ-terpinen-7-al i p-cimen. Međutim, kako je sadržaj etarskog ulja u plodovima kumina mali (ispod 5%), veliki deo biljnog materijala ostaje neiskorišćen. Primenom tzv. Folin-Ciocalteu metoda, ustanovljeno je da ostaci nakon destilacije etarskog ulja iz plodova kumina sadrže između 30.1 i 47.5 mg GAE/g suvog ekstrakta ukupnih polifenola. Hidroksibenzoeva i hidroksicimetna kiselina, kao i glikozidi flavonona i flavonola, su najzastupljeniji polifenoli. Na osnovu DPPH-metoda antioksidativni potencijal ostataka nakon destilacije plodova kumina je slab i kreće se između 0.02 i 0.04 mM TE/g. Dalja istraživanja bi trebalo usmeriti ka primeni ostataka nakon destilacije plodova kumina i drugih biljaka koje se koriste za destilaciju etarskih ulja u prehrambenoj industriji i poljoprivredi.
