TL;DR: In this paper, the granulometrics studies demonstrate that mill of the grain can destroy the original structure of a mill of a ring, and that the mill of kaolin in mills of rings causes a progressive destruction of their structure original.

TL;DR: Chmielewska et al. as discussed by the authors presented the results of experiments associated with color changes of various ceramic colouring agents utilised in marking and decoration of ceramics after illumination by means of the Nd:YAG picosecond laser.
Abstract: The authors present the results of experiments associated with colour changes of various ceramic colouring agents utilised in marking and decoration of ceramics after illumination by means of the Nd:YAG picosecond laser. The photographic illustration of the illumination effects was complemented by the results of examinations regarding surface topography and substantial chemical modifications of ceramic materials detected using methods of materials science.

TL;DR: In this article, the energy of the Montmorillonite ion, Δ F ≈−215 kJ mol −1, was calculated and the sign of Δ F corresponds to the substitution Ca 2+ →Mg 2+, which actually takes place the absolute values of the energetic yield of the exchange reaction exceed those found in the experiments by two orders of magnitude.

TL;DR: In this paper, three samples of terra rossa were shown to be efficient adsorbents of phosphate [P(V)] from wastewater and removed 29.6% of P(V).
Abstract: AB ST R ACT : Three samples of terra rossa were shown to be efficient adsorbents of phosphate [P(V)] from wastewater and removed 29.932.6% of P(V). The total iron content in terra rossa was the key factor which determined the P(V) removal from wastewater. The original samples of terra rossa were effective support materials for the immobilization of metabolically active P(V)accumulating bacteria Acinetobacter junii (0.562.47610 10 CFU g 1 ). The removal of oxalateextractable iron from original sample of terra rossa increased the number of immobilized bacteria to 1.34610 11 CFU g 1 , which is the largest number of immobilized bacteria reported in the literature so far. In reactors containing the A. junii and terra rossa P(V) was removed from wastewater by simultaneous adsorption onto terra rossa and accumulation inside bacterial cells, resulting in 40.562.5% of P(V) removal. Terra rossa is a promising substrate for biological P(V) removal from wastewater, acting both as adsorbent of P(V) and carrier of P(V)-accumulating bacteria.
