“…Obtained SEM data were further verified using atomic force microscopy. It is worth to note that AFM has proven to be a powerful visualization technique for a wide range of nanomaterials and nanoscale changes in the materials [51–53], including qualitative and quantitative analysis of nanopowders [54]. AFM allowed for 3D topography reconstruction and phase-contrast acquisition yielding for deeper insight into nanoscale features of the tested materials.…”

Nanomaterials, such as hydroxyapatite nanoparticles show a great promise for medical applications due to their unique properties at the nanoscale. However, there are concerns about the safety of using these materials in biological environments. Despite a great number of published studies of nanoobjects and their aggregates or agglomerates, the impact of their physicochemical properties (such as particle size, surface area, purity, details of structure and degree of agglomeration) on living cells is not yet fully understood. Significant differences in these properties, resulting from different manufacturing methods, are yet another problem to be taken into consideration. The aim of this work was to investigate the correlation between the properties of nanoscale hydroxyapatite from different synthesis methods and biological activity represented by the viability of four cell lines: A549, CHO, BEAS-2B and J774.1 to assess the influence of the nanoparticles on immune, reproductive and respiratory systems.

“…The polycrystalline BZBO compounds were obtained by sintering the stoichiometric raw materials at 600 °C using solid-state reaction method. The sintering temperature was slightly higher than the reported Pechini systhesis method . Below 600 °C, the BZBO phase was found difficult to obtain using solid-state reaction method (Figure a).…”

A Bi2ZnB2O7 single crystal measuring 45 mm × 35 mm × 15 mm was grown by using the Kyropoulos method. The as-grown crystal showed distinct crystal facets (001), (010), and (110), among others, which were consistent with the ideal growth morphology predicted by the Bravais-Friedel and Donnay-Harker method. The electric, elastic, and piezoelectric properties of the Bi2ZnB2O7 single crystal were examined, using the impedance and pulse-echo methods for the first time. The independent piezoelectric coefficients d 15, d 24, d 31, d 32, and d 33 were evaluated and found to be of the value of 1.4, −5.5, 2.5, −6.4, and 1.1 pC/N, respectively. The contributions of the crystal symmetry space group to the piezoelectric property were analyzed from the viewpoint of polyhedral distortion and net dipole moment. The temperature-dependent behaviors of the electroelastic properties were characterized in the temperature range from room temperature to 500 °C. Within this temperature range, the highest electromechanical coupling factor k 32 (14.5%) and piezoelectric coefficient d 33 (1.1 pC/N) exhibited temperature-independent behavior.

Influência do tipo de solvente na síntese de mulita pelo método Pechini

Resumo Mulita é um aluminossilicato com grande importância na tecnologia cerâmica. Sua síntese através de métodos químicos tem sido extensivamente estudada, no entanto, não se observam estudos da sua obtenção pelo método Pechini. Assim, este estudo teve por objetivo a síntese de mulita por meio deste método. Foi avaliada a influência de diversos solventes na obtenção da mulita pela rota Pechini. As características dos pós foram avaliadas por difração de raios X, análise térmica (TG/DTG), adsorção de nitrogênio (BET), microscopia eletrônica de varredura e de transmissão. Os resultados obtidos comprovaram a eficiência do método Pechini, bem como a influência dos solventes na obtenção da fase, sendo a mulita obtida como fase majoritária e com maior cristalinidade quando do uso do álcool etílico como solvente.
