TL;DR: In this paper, the role of accessory minerals in the dissolution process of ceramic grade kaolin was discussed in the light of the obtained data, and the results allowed to stress the importance of NaHMP in this process.

TL;DR: In this paper, concentrated dispersions (35% v, v) of ceramic grade kaolin dispersed with sodium hexametaphosphate (NaHMP) were prepared at three different experimental conditions: in distilled water at 30 and 60 °C, and in a 5*10 −3 M Ca(NO3)2·4H2O solution, at 30 °C.

TL;DR: In this article, a combined experimental/theoretical approach was used to determine the reorganization energy for a number of cytochrome c variants and compute structure-related properties relevant to the kinetics of the electron transfer process through molecular dynamics simulations.

TL;DR: The adsorption of hexametaphosphate ion, an important deflocculant used in the ceramic industry, from aqueous solutions onto kaolinite has been studied at different temperatures and the thermodynamic parameters DeltaG, DeltaH, and DeltaS were calculated and found to be consistent with an interaction model involving the formation of an inner-sphere complex between HMP and aluminol groups.

TL;DR: In this article, a baseline characterization of the source clay STx-1b was provided, which was the objective of this study, to provide researchers a tool useful not only for new investigation but also to compare new results obtained on STx1b with literature data on ST x-1a.
