“…Surface layers are specifically modified by the confinement of interlamellar water and by water adsorbed at the upper surface as well as by small differences concerning the clinochlore lattice parameter and distance between constituents (T-Oc-T or brucite-like (B) layers). For the water layer, we considered a typical thickness of 3.00 Å. , The parameters introduced to modify a given surface configuration are schematically represented in Figure S4, and their values are depicted in Table S1. In our model, we consider two parameters as layer shifts.…”

“…With regard to the water film formation on the surface of a cleaved mineral, another recent experimental–theoretical work suggested that water films grow anisotropically driven by defects that capture water vapor at higher RH environments (RH > 30%) . The adsorption of water molecules onto the surface of mica phyllosilicate minerals is known to form ice-like layers, although their exact ice phase is debated. ,− …”

Water is the matrix of life, and its confinement in nanocavities is a central topic from geophysics to nanotribology. Phyllosilicate layered minerals provide natural nanocavities for water due to their capacity to hydrate by confining water molecules in the interlamellar space. However, the hydration of phyllosilicates at the nanoscale is not a fully understood process and depends on the geological specimens. In this work, we report the formation of aqueous nanochannels in the interlamellar space of ultrathin clinochlore phyllosilicate mineral using infrared scattering-type scanning near-field optical microscopy and Kelvin probe force microscopy. We demonstrate that nanoconfinement of water in clinochlore changes the overall mechanical, optical, and dielectric properties of the system. We propose a capacitive model that describes the dielectric response of the aqueous nanochannels. Our model is endorsed by a robust crystal truncation rod analysis of synchrotron Xray diffraction data. We found that clinochlore termination combines hydrated structures ordered along the c-axis. We also find evidence of ice-like behavior of the water nanoconfined in clinochlore by Fourier-transform infrared spectroscopy. Notably, our work introduces clinochlore as a natural platform for water confinement in two-dimensional systems that can be engineered for several applications in the frontiers of nanotechnology.

“…We utilized an atomic force microscopy (AFM) to probe the adsorbed state of REEs on kaolinite under an in-situ aqueous environment. AFM with its remarkable sub-nanometer resolution provides surface information (e.g., morphology and charge) in a non-invasive manner [27][28][29][30] . Using force curve measurement of AFM, we investigated the interactions between REEs (La, Y, and Yb) and distinct planes (Si-basal and Al-basal planes) of kaolinite.…”

Regolith-hosted rare-earth element (REE) deposits are essential for supplying heavy-REEs (HREEs), meeting over 95% of global demand. In weathering crusts, REE enrichment and fractionation form these valuable deposits. While REEs are commonly thought to adsorb onto the Al-basal plane of kaolinite, the atomic-scale adsorption state has not been visualized, and the role of clay minerals in REE fractionation is debated. Using high-resolution atomic force microscopy (HR-AFM), we visualize the atomic-scale adsorption of light-REEs (LREEs) and HREEs on the Si-basal and Al-basal planes of kaolinite in aqueous solutions. Our results show that REEs primarily adsorb on the Si-basal plane, forming a "triangle" pattern, with HREEs preferentially adsorbed over LREEs, unequivocally establishing that clay minerals affect REE fractionation. This adsorption behavior is confirmed on mica, which also exposes Si-basal planes. This study reveals the unexpected significance of the Si-plane in REE adsorption, providing atomic-scale insights into REE enrichment and fractionation mechanisms during the metallogenetic process of regolith-hosted REE deposits. Moreover, the elucidated activity and specificity of the Si-basal plane indicate significant implications for various geochemical processes, such as elemental immobilization, transport, and cycling, due to the abundance of silicates within Earth’s crust.
