In this study, Young’s moduli (E) of 28-day concrete determined through destructive tests according to NBR 8522−2017 were compared with results of nondestructive tests, such as the ultrasonic pulse velocity (UPV) and impulse excitation technique

We investigated the Li+ ion incorporation in Ba2GdNbO6:Eu3+ perovskite by atomistic simulations based on energy minimization. We predicted the most probable sites occupied by Eu3+ and Li+ ions and the related charge-compensation mechanisms involved i

In this work we investigated the phase formation and structural ordering of Ba$_{3}$B$^{'}$Nb$_{2}$O$_{9}$ (B$^{'}$ $=$ Ca and Zn) perovskite powders obtained by a modified polymeric precursor route using X-ray powder diffraction and Raman spectrosco

In this work we performed a detailed investigation about ordering in \bcn perovskite. The sintering temperature and time were changed to obtain samples with different ordering. The order parameters were probed by Raman spectroscopy based on a partial

In this work nanometric spinel Co${}_{1-x}$Cu${}_{x}$Fe${}_{2}$O${}_{4}$ powders were obtained by polymeric precursors method at several annealing temperatures between 700 and 1200 ${}^\circ$C. The samples were characterized by means of X-ray powder

We performed Raman spectroscopy measurements under temperature changes from 10 K up to 850 K to probe the phonon-spin coupling in Y$_2$NiMnO$_6$. The spin-phonon coupling was observed as a softening of the stretching mode, indicating this phonon stab
