Наиме, одабрана је фосфор-волфрамовa бронза (WPB; PW8O26) синтетисана на 650oC, и анализирана у Pmnb [8] и P4/ncc [9] просторним групама, а које су одговарајуће за различите WO3 полиморфне фазе.

AB  - It is well known that the baseline can significantly influence to the results of the Rietveld analysis [1, 2]. This influence was studied with Fullprof programme in one of the phosphorus-tungsten compounds [3–7]. Namely, phosphor-tungsten bronze (WPB; PW8O26) synthesized at 650 °C was selected and analyzed in the Pmnb [8] and P4/ncc [9] space groups, which are adequate to the different WO3 polymorph phases. Four methods of specifying the base line were applied: Chebyshev polynomial with 6 (i) and 4 (ii) coefficients; and linear interpolation between points with approximately equal distances between points (iii) and avoiding reflection zones (iv), as well. From the obtained results it can be concluded: a) that the Yobs–Ycalc values are very good in all cases; b) that the lowest agreement factors are obtained with option iii, while multiple higher ones are obtained with options i and ii; and c) that the calculated interatomic distances and angles differ significantly from each other. The complex appearance of the baseline is the mоst significant problem in the refinement. The influence of pseudosymmetry contributes to the instability of the refinement.

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).

abstract = "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  - A modified reverse co-precipitation method using glacial acetic acid to synthesize α-Bi2O3
structures is presented. The formation of an almost pure rod-like α- Bi2O3 microstructure was
confirmed by X-ray powder diffraction and scanning and transmission electron microscopy
analyses. A glassy carbon paste (GCP) electrode was modified with the obtained material in aim
of development of an electrochemical sensor for acetaminophen (APAP) detection using
differential pulse voltammetry (DPV). Cyclic voltammetry revealed better performance of the
GCP@Bi2O3 electrode in comparison to the bare GCP. The prepared GCP@Bi2O3 sensor
successfully detected APAP in the linear concentration range from 0.05 to 12.00 μM, with the
limit of quantification (LOQ) and the limit of detection (LOD) of 36 nM and 10 nM, respectively.
Furthermore, the designed sensor showed pronounced precision, repeatability, and selectivity
toward APAP detection. The GCP@Bi2O3 sensor and associated DPV method demonstrated high
accuracy, precision, and practical utility for real-time APAP quantification in pharmaceutical
products like Caffetin®. A comparison of declared and measured APAP levels revealed excellent
recovery rates, with minimal impact from other formulation components.

AB  - Metals and metal oxides have subpar antibacterial activities compared to those of small-molecule antibiotics, yet there are hopes that with proper compositional and structural adjustments this gap might be bridged. In this study, titanium dioxide (TiO2) nanoparticles were mechanically activated and combined with particulate silver through simple reduction process elicited by UV irradiation and assisted with the ultrasound. The resulting powders in various combinations (Ag vs. no Ag, activated vs. non-activated) were characterized using a range of experimental techniques and assessed for their antibacterial activities. The preparation procedure presented in this work prevails over the disadvantages of many chemical routes, most critically by avoiding the use of toxic substances. The mechanical activation did not reduce the particle size or crystallinity of TiO2 nor did it consistently alter the bandgap, yet it enabled the doubling of the amount of silver incorporable into the material. Further, while both mechanical activation and the addition of silver in the amount not exceeding 0.5 wt% produced barely detectable structural changes in the material, they both augmented its antibacterial activity. The precursor TiO2 powder produced no inhibition zone against any of the four bacterial species tested, while the mechanical activation of TiO2 led to the formation of distinct inhibition zones against each of the four bacterial species tested. The addition of silver to activated TiO2 further widened the inhibition zones and it also imparted the antibacterial activity to non-activated TiO2. The boost in the antibacterial activity achieved by the short mechanical activation was of a similar magnitude as the boost obtained after the addition of silver. The antibacterial activity was not different for different species when no silver was added to the system. However, with the addition of silver, species selectivity was obtained, as the composites were more effective against the two Gram-negative species (Escherichia coli and Klebsiella pneumoniae) than against the two Gram-positive ones (Staphylococcus aureus and Bacillus subtilis). The antibacterial activity increased with the addition of silver in the broth assay, but it was mediocre compared to that detected in the agar assay, attesting to the poor dispersability of the powders and their best performance when the bacterial cells migrate to the composite surface than vice versa. The findings of this study give hope that with appropriate microstructural or compositional alterations, the antibacterial activity of metal oxide powders and inorganic materials in general can be made comparable to that of small-molecule antibiotics.

AB  - The reverse co-precipitation method combined with calcination was applied to synthesize α-Bi2O3 rod-like microstructures. The standard co-precipitation and reverse co-precipitation approaches include using nitric acid to dissolve bismuth nitrate as a source of Bi3+ ions [1,2]. In this study, the procedure was modified since glacial acetic acid was used instead of HNO3. To the best of our knowledge, there is no literature data for the preparation of α-Bi2O3 by reverse co-precipitation using acetic acid up to now. The phase analyses calculated by the relative intensity ratio (RIR) method were obtained using the PDXL2 integrated XRPD software (Ver. 2.8.4.0; Rigaku Corporation). XRPD revealed a presence of Bi2O3 composed of P21/c polymorph (α- Bi2O3) modification (96.3(1) %). The unit cell parameters calculated by the Reference Intensity Ratio (RIR) method were close to reference values (PDF # 01-070-8243). The ω-Bi2O3 (P31c) was found in the minority (3.7(1) %). The presence of Bi2O3 (P21/c, PDF # 01-080-2589) and Bi6O7 (I4/mmm, PDF # 03-065-5490) near the limit of detection might be possible. Fourier Transform Infrared Spectroscopy (FTIR) was also used to confirm the presence of Bi2O3. The rod-like morphology was confirmed by Scanning and Transmission Electron Microscopy (SEM and TEM). The Bi2O3 particles prepared by the modified reverse co-precipitation route combined with calcination are smaller in comparison to particles synthesized by standard reverse co-precipitation procedures, which include the usage of nitric acid [2]. The obtained results gave us hope that the presented synthesis approach may be a good platform for producing rod-like microstructures of α-Bi2O3, which might be successfully applied in electrochemistry and catalysis.
AB  - Метода реверзне копреципитације комбинована са калцинацијом употребљена је при синтези α-Bi2O3 штапићастих микроструктура. Стандардни приступи при употреби ових метода за синтезу бизмут-оксида подразумевају коришћење азотне киселине при растварању бизмут-нитрата који представља извор Bi3+ јона [1,2]. У овој студији, метода реверзне копреципитације је модификована јер је уместо азотне коришћена глацијална сирћетна. Нису пронађени литературни подаци који указују на употребу сирћетне киселине при синтези честица α-Bi2O3 методом реверзне копреципитације што ову студију чини иновативном. Фазна анализа изведена је помоћу RIR (Reference Intensity Ratio) методе инкорпориране у PDXL2 интегрисани XRPD софтвер (верзија 2.8.30; Rigaku Corporation). Резултатима рендгенске структурне анализе утврђено је присуство α-Bi2O3 полиморфа (P21/c) у количини од 96,3(1)%. Параметри јединичне ћелије утачњени су уз помоћ RIR методе и блиски су референтним вредностима (PDF # 01-070-8243). Потврђено је и присуство ω-Bi2O3 полиморфа у незнатној количини (3,7(1)%). Постоји могућност присуства фаза Bi2O3 (P21/c, PDF # 01-080-2589) и Bi6O7 (I4/mmm, PDF # 03-065-5490) близу границе детекције. Штапићаста морфологија добијених честица потврђена је СЕМ и ТЕМ методама. Честице Bi2O3 припремљене модификованом методом реверзне копреципитације комбиноване са калцинацијом знатно су мање у поређењу са честицама синтетисаним стандардним техникама реверзне копреципитације које укључују употребу азотне киселине [2]. Добијени резултати показују добру перспективу за употребу приказане методе синтезе при припреми α-Bi2O3 микроструктура које могу наћи потенцијалну примену у електрохемији и катализи.

AB  - The reverse co-precipitation method combined with calcination was applied to synthesize α-Bi2O3 rod-like microstructures. The standard co-precipitation and reverse co-precipitation approaches include using nitric acid to dissolve bismuth nitrate as a source of Bi3+ ions [1,2]. In this study, the procedure was modified since glacial acetic acid was used instead of HNO3. To the best of our knowledge, there is no literature data for the preparation of α-Bi2O3 by reverse co-precipitation using acetic acid up to now. The phase analyses calculated by the relative intensity ratio (RIR) method were obtained using the PDXL2 integrated XRPD software (Ver. 2.8.4.0; Rigaku Corporation). XRPD revealed a presence of Bi2O3 composed of P21/c polymorph (α- Bi2O3) modification (96.3(1) %). The unit cell parameters calculated by the Reference Intensity Ratio (RIR) method were close to reference values (PDF # 01-070-8243). The ω-Bi2O3 (P31c) was found in the minority (3.7(1) %).

AB  - A modified reverse co-precipitation method using glacial acetic acid to synthesize α-Bi2O3 structures is presented. The formation of an almost pure rod-like α- Bi2O3 microstructure was confirmed by X-ray powder diffraction and scanning and transmission electron microscopy analyses. A glassy carbon paste (GCP) electrode was modified with the obtained material in aim of development of an electrochemical sensor for acetaminophen (APAP) detection using differential pulse voltammetry (DPV). Cyclic voltammetry revealed better performance of the GCP@Bi2O3 electrode in comparison to the bare GCP. The prepared GCP@Bi2O3 sensor successfully detected APAP in the linear concentration range from 0.05 to 12.00 μM, with the limit of quantification (LOQ) and the limit of detection (LOD) of 36 nM and 10 nM, respectively. Furthermore, the designed sensor showed pronounced precision, repeatability, and selectivity toward APAP detection. The GCP@Bi2O3 sensor and associated DPV method demonstrated high accuracy, precision, and practical utility for real-time APAP quantification in pharmaceutical products like Caffetin®. A comparison of declared and measured APAP levels revealed excellent recovery rates, with minimal impact from other formulation components.

AB  - It is well known that the baseline can significantly influence to the results of the Rietveld analysis [1,2]. This influence was studied with Fullprof programme in one of the phosphorus-tungsten compounds [3-7]. Namely, phosphor-tungsten bronze (WPB; PW8O26) synthesized at 650oC was selected and analyzed in the Pmnb [8] and P4/ncc [9] space groups, which are adequate to the different WO3 polymorph phases. Four methods of specifying the base line were applied: Chebyshev polynomial with 6 (i) and 4 (ii) coefficients; and linear interpolation between points
with approximately equal distances between points (iii) and avoiding reflection zones (iv), as well.
From the obtained results it can be concluded: a) that the Yobs –Ycalc values are very good in all cases (Figure 1); b) that the lowest agreement factors are obtained with option iii, while multiple higher ones are obtained with options i and ii (Table 1); and c) that the calculated interatomic distances and angles differ significantly from each other (Figures 2 and 3; Table 2; deviations
were marked with red color). The complex appearance of the baseline is the mоst significant
problem in the refinement. The influence of pseudosymmetry contributes to the instability of the
refinement.

AB  - To investigate the influence of spinel structure and sintering temperature on the functional properties of BaTiO3/NixZn1−xFe2O4 (x = 0, 0.5, 1), NiFe2O4, ZnFe2O4, and Ni0.5Zn0.5Fe2O4 were in situ prepared by thermal decomposition onto BaTiO3 surface from acetylacetonate precursors. As-prepared powders were additionally sintered at 1150 °C and 1300 °C. X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) coupled with electron dispersive spectroscopy (EDS) were used for the detailed examination of phase composition and morphology. The magnetic, dielectric, and ferroelectric properties were investigated. The optimal phase composition in the BaTiO3/NiFe2O4 composite, sintered at 1150 °C, resulted in a wide frequency range stability. Additionally, particular phase composition indicates favorable properties such as low conductivity and ideal-like hysteresis loop behavior. The favorable properties of BaTiO3/NiFe2O4 make this particular composite an ideal material choice for further studies on applications of multi-ferroic devices.

AB  - In order to examine the influence of phase composition and sintering temperature on the functional properties of perovskite/spinel composites, BaTiO3/NixZn1−xFe2O4 (x = 0, 0.5, 1), NiFe2O4, ZnFe2O4, and Ni0.5Zn0.5Fe2O4 were in situ prepared by thermal decomposition onto BaTiO3 surface. Acetylacetonate complexes were used as the precursors. The obtained powders were compressed to pellets and sintered at 1150 °C and 1300 °C. X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) coupled with electron dispersive spectroscopy (EDS) were used for the comprehensive investigation of phase composition and morphology. The magnetic, dielectric, and ferroelectric properties were performed in detail. The optimal phase composition was found in the BaTiO3/NiFe2O4 composite sintered at 1150 °C, which resulted in a wide frequency range stability. Furthermore, particular phase composition led to suitable properties such as low conductivity and ideal-like hysteresis loop behavior [1]. These functional properties of BaTiO3/NiFe2O4 make this composite a “material of choice“ for further studies on applications of multiferroic devices.
AB  - U cilju ispitivanja uticaja faznog sastava i temperature sinterovanja na funkcionalna svojstva perovskit/spinel kompozita BaTiO3/NixZn1−xFe2O4 (x = 0, 0,5, 1), NiFe2O4, ZnFe2O4, i Ni0,5Zn0,5Fe2O4 pripremljeni su in situ metodom termalne dekompozicije. U sintezi su korišćeni acetilacetonatni kompleksi kao prekursori. Dobijeni prahovi su komprimovani u tablete i sinterovani na 1150 °C i 1300 °C. Za detaljno ispitivanje faznog sastava i morfologije sintetisanih kompozita korišćene su metode rendgenske difrakcije praha (XRPD) i skenirajuće elektronske mikroskopije (SEM) spregnute sa energetsko disperzivnom spektroskopijom (EDS). Ispitivana su i magnetna, dielektrična i feroelektrična svojstva sinterovanih kompozita. Ustanovljeno je da optimalni fazni sastav pronađen kod kompozita BaTiO3/NiFe2O4 sinterovanog na 1150 °C dovodi do stabilnosti u širokom opsegu frekvencija. Optimalni fazni sastav pomenutog kompozita povoljno je uticao na funkcionalna svojstva kao što su niska provodnost i feroelektrično ponašenje koje se ogleda u zadovoljavajućem izgledu histerezisa [1]. Ova svojstva nedvosmisleno ukazuju da je kompozit BaTiO3/NiFe2O4 odgovarajući izbor za dalja istraživanja posvećena primeni multiferoičnih materijala.

AB  - To investigate the effect of synthesis procedure and sintering temperature on the functional properties of perovskite/spinel ceramics, BaTiO3/CoFe2O4 composites were prepared by thermal decomposition, coprecipitation, and microemulsion method, and sintered at 1150°C and 1300°C. The phase composition and morphology of as-prepared powders as well as sintered ceramics were thoroughly examined by X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) coupled with electron dispersive spectroscopy (EDS). The dielectric and ferroelectric measurements were performed in detail. Generally, the samples sintered at 1300°C had better performances than those sintered at 1150°C. The composite synthesized by thermal decomposition and sintered at 1300 °C stands out among other prepared BaTiO3/CoFe2O4 ceramics, owing to high stability in the wide frequency range and low leakage currents. The obtained results indicate that such composite might be successfully applied as a functional multiferroic.

AB  - Four macroscopically visible B–E (rim) zones, within a large natural ferric grossular garnet of Grs58–64Adr36–42Sps2 composition, are described by means of Rietveld refinements of the crystal structures in a series of six space groups, followed by comparative analysis of the R-values, site occupancy factors, and bond lengths and angles. The garnet crystallized in the rhombohedral R-3c space group. Various polyhedral distortions and structural order-disorder variations between the zones studied are also described and discussed. The rhombohedral symmetry of the ferric grossular garnet analysed can be regarded as primary, residual strain being a secondary cause for its slight optical anisotropy.

AB  - A size-strain line-broadening analysis of the XRPD patterns and Raman spectra for two anatase/brookite (TiO2)-based nanocomposites with carbon (C) was carried out and the results compared with those of a similar sample free of carbon. The crystal structures and microstructures of anatase and brookite, as well as their relative abundance ratio, have been refined from XRPD data by the Rietveld method (the low amount of carbon is neglected). The XRPD size-strain analysis resulted in reliable structure and microstructure results for both anatase and brookite. The experimental Raman spectra of all the samples in the region 100-200 cm-1are dominated by a strong feature primarily composed of the most intense modes of anatase (Eg ) and brookite (A 1g ). The anatase crystallite sizes of 14-17 nm, estimated by XRPD, suggest the application of the phonon confinement model (PCM) for the analysis of the anatase Eg mode, whereas the relatively large brookite crystallite size (27-29 nm) does not imply the use of the PCM for the brookite A 1g mode. Superposition of the anatase Eg mode profile, calculated by the PCM, and the Lorentzian shape of the brookite A 1g mode provide an appropriate simulation of the change in the dominant Raman feature in the spectra of TiO2-based nanocomposites with carbon. Raman spectra measured in the high-frequency range (1000-2000 cm-1) provide information on carbon in the investigated nanocomposite materials. The results from field-emission scanning electron microscope (SEM), thermogravimetric analysis (TGA), Fourier transform infrared (FTIR) spectroscopy and nitrogen physisorption measurements support the XRPD and Raman results.

The results from field-emission scanning electron microscope (SEM), thermogravimetric analysis (TGA), Fourier transform infrared (FTIR) spectroscopy and nitrogen physisorption measurements support the XRPD and Raman results.",

AB  - Poor water solubility of new chemical entities is considered as one of the main obstacles in drug development, as it usually leads to low bioavailability after administration. To overcome these problems, the selection of the appropriate formulation technology needs to be based on the physicochemical properties of the drug and introduced in the early stages of drug research. One example of the new potential drug substance with poor solubility is DK-I-60-3, deuterated pyrazoloquinolinone, designed for the treatment of various neuropsychiatric disorders. In this research, based on preformulation studies, nanocrystal technology was chosen to improve the oral bioavailability of DK-I-60-3. Nanocrystal dispersions stabilized by sodium lauryl sulfate and polyvinylpyrrolidone were prepared by modified wet media milling technique, with the selection of appropriate process and formulation parameters. The nanoparticles characterization included particle size and zeta potential measurements, differential scanning calorimetry, X-ray powder diffraction, dissolution and solubility study, and in vivo pharmacokinetic experiments. Developed formulations had small uniform particle sizes and were stable for three months. Nanonization caused decreased crystallite size and induced crystal defects formation, as well as a DK-I-60-3 solubility increase. Furthermore, after oral administration of the developed formulations in rats, two to three-fold bioavailability enhancement was observed in plasma and investigated organs, including the brain.

AB  - In this paper, grandite core with Grs64±1Adr36±1Sps2 composition was crystallographically studied. This core represents zone A of the macroscopically visible five A–E zones of the optically anisotropic Grs58–64Adr36–42Sps2 grandite. The applied procedure includes the detailed analysis of the powder diffraction patterns, and the Rietveld refinements of the crystal structures in a series of 18 space groups and two mixtures, which were followed by the comparative analysis of the R-values, site occupancy factors, and the bond lengths and angles. Synthesis of all of the presented results allows us to undoubtedly conclude that studied grandite is not cubic, neither as monophase nor as multiple phases in a mixture. Namely, it was established that structural dissymmetrization occurred and that it crystallized in the disordered rhombohedral R-3c or orthorhombic Fddd space groups, whereby the first one is more probable. Beside the established lower symmetry of the studied grandite, which could be treated as the primary cause, the residual strain is also not excluded as the second possible cause for its slight optical anisotropy.

AB  - As the number of poorly soluble drugs is increasing, nanocrystals have become very interesting due to wide range of application possibilities. Curcuminwas used as a model active ingredient in this work. Even though it has many proven positive effects, due to its physicochemical issues, its possibilities have not been fully exploited. The goal of this work was to select optimal conditions for a top-down method for curcumin nanosuspension production, and to perform their comprehensive characterization applying complementary methodologies: dynamic light scattering, polarization and atomic force microscopy, thermal analysis, X-ray powder diffraction, antioxidant activity evaluation, release kinetics assessment, and screening of potential biological effects applying cell viability assays on normal human lung fibroblasts, human melanoma and human adenomacarcinoma cells. After 30 min of milling, nanosuspensions stabilized by polysorbate 80 and by its combinations with sucrose palmitate showed good stability, while curcumin crystal structure was unaltered. Obtained nanocrystals were well defined, with average diameter 120-170 nm and PDI of about 0.25, zeta potential was below -30 mV and pH~5 for all formulations. Nanodispersions exhibited high antioxidant potential and improved dissolution rate compared to the corresponding coarse dispersions. Although curcumin nanodispersions exhibited significant antiproliferative effect to each cancer cell line, the highest effect was towards adenocarcinoma cells.

AB  - Mesoporous anatase nanopowders were doped with 0.05−0.5 mol% of W6+, in order to obtain more efficient photocatalyst than TiO2 Degussa P25 in the degradation of amitriptyline (AMI) under simulated solar irradiation (SSI). Dominant XRPD peaks were ascribed to anatase phase, with additional peaks which could correspond to brookite, TiO2 bronze and sodium titanate, Na2Ti9O19. The Raman scattering measurements have confirmed anatase as dominant phase, with broad Raman feature at ~270 cm−1 possibly related to Ti–O–Na stretching vibration. All W-doped nanopowders have shown enhanced adsorption and higher efficiency in photodegradation of AMI in comparison to TiO2 Degussa P25 under the same conditions. The catalyst doped with 0.4 mol% of W6+, which has shown the highest efficiency in degradation of AMI under SSI, has
also been tested in degradation of alprazolam (ALP). The effect of substrate type (AMI and ALP), catalyst loading, and initial substrate concentration on photocatalytic degradation using SSI was examined. The identification of the species responsible for the photocatalytic degradation of AMI and ALP by the catalyst doped with 0.4 mol% of W6+ was performed in the presence of various scavengers under SSI. The major role in degradation of AMI may be attributed to hydroxyl radicals, whereas superoxide anion radicals, singlet molecular oxygen and hydroxyl radicals contribute to degradation of ALP.

abstract = "Mesoporous anatase nanopowders were doped with 0.05−0.5 mol% of W6+, in order to obtain more efficient photocatalyst than TiO2 Degussa P25 in the degradation of amitriptyline (AMI) under simulated solar irradiation (SSI). Dominant XRPD peaks were ascribed to anatase phase, with additional peaks which could correspond to brookite, TiO2 bronze and sodium titanate, Na2Ti9O19. The Raman scattering measurements have confirmed anatase as dominant phase, with broad Raman feature at ~270 cm−1 possibly related to Ti–O–Na stretching vibration. All W-doped nanopowders have shown enhanced adsorption and higher efficiency in photodegradation of AMI in comparison to TiO2 Degussa P25 under the same conditions. The catalyst doped with 0.4 mol% of W6+, which has shown the highest efficiency in degradation of AMI under SSI, has
also been tested in degradation of alprazolam (ALP). The effect of substrate type (AMI and ALP), catalyst loading, and initial substrate concentration on photocatalytic degradation using SSI was examined. The identification of the species responsible for the photocatalytic degradation of AMI and ALP by the catalyst doped with 0.4 mol% of W6+ was performed in the presence of various scavengers under SSI. The major role in degradation of AMI may be attributed to hydroxyl radicals, whereas superoxide anion radicals, singlet molecular oxygen and hydroxyl radicals contribute to degradation of ALP.",

AB  - Herein we report effects of partial substitution of Fe3+ by Y3+ in magnetite (Fe3O4) on morphology and inorganic arsenic species adsorption efficiency of the Fe3−x Y x O4 nanoparticles formed. The series of Fe3−x Y x O4 (x = 0.00, 0.042 and 0.084, labeled as Y00, Y05 and Y10, respectively) was synthesized using co-precipitation followed by microwave-hydrothermal treatment (MW) at 200 °C. With increase of yttrium content (x value), both the morphological inhomogeneity of the samples and the fraction of spinel nanorods as compared to spinel pseudospherical particles increased. By both transmission electron microscopy and x-ray powder diffraction analyses, it was determined that the direction of growth of the spinel nanorods is along the [110] crystallographic direction. The Fe3−x Y x O4 affinities of adsorption toward the inorganic arsenic species, As(III) (arsenite, AsO3 3−) and As(V) (arsenate, AsO4 3−), were investigated. Increased Y3+ content related to changes in sample morphology was followed by a decrease of As(III) removal efficiency and vice versa for As(V). The increase in Y3+ content, in addition to increasing the adsorption capacity for As(V), significantly expanded the optimum pH range for the maximum removal and decreased the contact time for necessary 50% removal (t 1/2) of As(V) (Y00: pH 2–3, t 1/2 = 3.12 min; Y05: pH 2–6, t 1/2 = 2.12 min and Y10: pH 2–10, t 1/2 = 1.12 min). The results point to incorporation of Y3+ in the crystal lattice of magnetite, inducing nanorod spinel structure formation with significant changes in sorption properties important for the removal of inorganic arsenic from waters.
