Ozone/activated carbon coupling could be an efficient method to remove micropollutants, such as phthalates, that are refractory to classical treatments. However, this wastewater-treatment process can lead to the formation of oxidation by-products tha

International audience; The adsorption of diethyl phthalate (DEP) was studied on four activated carbons (ACs) with different chemical and microporous properties. The kinetic results showed that the non-linear form of the pseudo-second order kinetic m

Aluminate glasses are important materials from a fundamental structural point of view because Al is the only network former. They present also a technological interest because of their good IR transmission and ultralow optical losses. Aluminum in gla

BaSn 0.7 Sb 0 . 3 O 3 has been synthesized for the first time. This result is original because up to now the solubility limit of the Ba(Sn 1− x Sb x )O 3 series was found to be x =0.2. The electronic carrier concentration is prevented from screenin

Laser ablation by varying the number of consecutive laser pulses upon two targets, one superconducting YBa 2 Cu 3 O 7 , the other insulating MCuO 2 (M=Sr, Ca), is used to build thin films of tuneable average compositions. Most of the samples are foun

A modified sol-gel method is used to prepare stoichiometric, homogeneous barium stannate powders. The synthesis process is described in detail in this paper. One of the main characteristics of this process is that monophasic powders are obtained easi

Whereas a transition from metal to superconductor behaviour is observed upon substituting Pb for Bi in the perovkite Ba(Pb, Bi)O3 system, no similar transition is present in Ba(Sn, Sb)O3 system, although these systems have the same structure. The phe

The synthesis of a new layered perovskite family is reported. The phase (Ba1−xKx)2(Pb1−y,Biy)O4 is the n = 2 member of Ruddlesden-Popper series An +1B,nO3n + 1. The compounds have tetragonal symmetry and their space group is I4/mmm. Single phasic

From X-ray diffraction, polarization and dielectric measurements, it is shown that a 0.9 Pb(Mg 1 3 Nb 2 3 )O 3 - 0.1 PbTiO3 ceramic undergoes a zero-field rhombohedral phase transition. This material transforms spontaneously from a relaxor into a nor
