Charge Heterogeneity in Smectites
Clays and Clay Minerals, 1983 AbstractThe heterogeneity of sites for Ca→K exchange was examined by microcalorimetry in the <0.2-μm fractions of some selected smectites. Six groups of sites, ranging in exothermic exchange enthalpy (-d(ΔHx)/dx) from 5.7 to 10.9 kJ/eq were identified.

Natural Mordenite from Spain as Pozzolana
Molecules, 2020 This work deals with anomalous concentrations of natural mordenite in the southeast of Spain. The X-ray diffraction (XRD) and scanning electron microscopy (SEM) studies evidenced that the samples contain mainly monomineral zeolitic phase of mordenite (70%

Smectite promotes probiotic biofilm formation in the gut for cancer immunotherapy
Cell Reports, 2021 Summary: Administration of probiotics to regulate the immune system is a potential anti-tumor strategy. However, oral administration of probiotics is ineffective because of the poor inhabitation of exogenous bacteria in host intestines.
