“…The kaolin in this study was not only a disperser and stabilizer; it also acted as an adsorbent after calcination. This led to an increase in ion exchange capacity [11], confirmed by SEM images and XRD patterns in the following section. Fig.…”

“…Understanding the reaction mechanism in short-term is important if one want to optimize the lime treatment technique. In addition, the short-term reaction (first minute up to 24 h after mixing) is a crucial stage as it determines the long-term characteristics (durability and mechanical characteristic) of treated material (Konan et al, 2009).…”

“…Vimonses et al performed a series of acid (H 2 SO 4 )/ alkaline (NaOH)/thermal (calcination at 750°C) treatments to alter the surface properties of the KLT [14]. Taking into account that the dehydroxylation of KLT to the metakaolinite phase occurs in the temperature range 450-700°C [48][49][50], we are actually dealing with a different type of material in these two works [14,20].…”

The adhesion of TiO(2) (anatase structure) nanoparticles to kaolinite substrate was investigated using molecular modeling. Universal force field computation, density function theory computation, and a combination of both two approaches were used. This study enabled the adhesion energy for the TiO(2)/kaolinite nanocomposite to be estimated, and revealed the preferred orientation of the TiO(2) nanoparticles on the kaolinite substrate. The results of all three levels of computation were compared in order to show that the accuracy of universal force field computations is sufficient in this context. The role of nanoparticle size and the importance of the nanoparticle-substrate bonding contribution are presented here and discussed. A comparison of the molecular modeling results with scanning electron microscopy observations showed that the results of the modeling were consistent with the experimental data, and that this approach can be used to help characterize nanocomposites of the nanoparticle/phyllosilicate substrate type.
