TL;DR: Investigating the effect of sonication on the particle size and structure of a well-crystallized (KGa-1) kaolinite from Georgia showed that particle-size reduction can be controlled through different variables such as power of ultrasonic processor, amount of sample, and time of treatment.

TL;DR: In this article, the authors compared the results of SH (fresh paste) and of TG (the aged one), to verify the assumptions made on SH interpretation and to check the change in hydration products with ageing as measured by phase transformation on heating (M versus the final mass).

TL;DR: In this article, the effects of ultrasound treatment on dickite from Tragos, Mangualde, in Portugal, were reported, where the elongated crystals observed in the sample are broken up, after their treatment, along the cleavage planes 001 and 110, mainly along the largest direction (a axis), into smaller units that retain the typical lamellar morphology of the starting crystals.

TL;DR: In this paper, the preparation and characterization of porous clay heterostructures (PCH) as a high-surface area support for CuO-CeO 2 based catalysts for the preferential oxidation of CO in excess of H 2 (CO-PROX) was reported.

TL;DR: In this article, the texture, structure and acidic properties of the obtained PCH samples were characterized by SEM, BET, XRD, FTIR, DTA-TG, NH3-TPD and 1-butene isomerization.
