Deposition, diagenetic and hydrothermal processes in the Aptian Pre-Salt lacustrine carbonate reservoirs of the northern Campos Basin, offshore Brazil
TL;DR: A study integrating systematic petrography, cathodoluminescence, scanning electron microscopy, microprobe and X-ray diffraction was performed on seven wells in the northern Campos Basin this article, with the aim to improve our understanding of the factors that influence the porosity and permeability distribution in these important lacustrine carbonate reservoirs.

High strain (0.4%) Bi(Mg2/3Nb1/3)O3-BaTiO3-BiFeO3 lead-free piezoelectric ceramics and multilayers
Shunsuke Murakami,Dawei Wang,Ali Mostaed,Amir Khesro,Antonio Feteira,Derek C. Sinclair,Zhongming Fan,Xiaoli Tan,Ian M. Reaney +8 more
TL;DR: In this paper, the authors investigated the relationship between the piezoelectric properties and the structure/microstructure for 0.05Bi(Mg2/3Nb1/3)O3-(0.95-x)BaTiO3-xBiFeO3 (BBFT, x = 0.63, 0.60,0.65, 0,75) ceramics and found that BBFT transformed from relaxor-like to ferroelectric behaviour with an increase in x, consistent with changes in the phase assemblage and

Xrd, ftir, and thermal analysis of bauxite ore-processing waste (red mud) exchanged with heavy metals
TL;DR: In this paper, the results of X-ray diffraction (XRD), Fourier transform infrared (FTIR), and thermal analysis of untreated (RMnt) and acid-treated red mud (RMa), a bauxite ore-processing waste, exchanged with Pb2+, Cd2+, and Zn2+ cations were performed in order to investigate the changes in the sorbent structure caused by the exchange with metals of different ionic radii.

Influence of A-site cation mismatch on structural, magnetic and electrical properties of lanthanum manganites
TL;DR: In this paper, the influence of cation mismatch on magnetic as well as electrical behavior of manganite perovskites has been investigated with X-ray diffraction (XRD) data, and it has been concluded that the electrical resistivity data in the ferromagnetic (metallic) regime $(T T_P)$ also influences $T T _C$ values.
