Million‐Year Scale Hydrothermal and Hydrocarbon Evolution Hosted Within Stratified Thermohydraulic Systems in Sedimented Ultraslow‐Spreading Settings, Svyatogor and Vestnesa Ridges

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Hydrothermal systems at ultraslow‐spreading ridges are poorly understood, especially where thick sediments overlay detachment faults. The International Ocean Discovery Program Expedition 403 obtained the longest sediment record in Atlantic‐Arctic ultraslow‐spreading systems, reaching ∼628 m below the seafloor.

Enrichment of Smectite in the REY‐Rich Mud of the Clarion‐Clipperton Fracture Zone in the Eastern Pacific and Its Geological Significance

Geochemistry, Geophysics, Geosystems
REY‐rich mud, consisting of deep‐sea sediments with high concentrations of rare‐earth elements and yttrium (REY), holds significant economic potential.

Multi‐Stimuli Responsive Angstrom‐Scale Two‐Dimensional Channels of Natural Layered Materials

Advanced Materials, Volume 38, Issue 59, 22 October 2026.
Å‐scale ion channels naturally formed within the interlayers of vermiculite clay enable ionic current modulation in response to mechanical, chemical, and electrical stimuli. Coupled pressure and electric fields induce reversible streaming current (Istream) polarity inversion, which is explained by a modified surface charge regulation model.

Re-evaluating the evidence of aflatoxin B1 intercalation into smectite interlayer: a review based on basal spacing data

Sains Tanah: Journal of Soil Science and Agroclimatology
The bonding mechanism of aflatoxin B1 (AfB1) onto smectite in the batch adsorption test remains a subject of ongoing debate. One key aspect under contention is whether the interlayer of smectite is accessible to the AfB1 molecule.

Laboratory vs. pilot scale calcination of illitic and smectitic clays

ce/papers, Volume 9, Issue 6, Page 280-293, October 2026.
Abstract One strategy to reduce the carbon footprint of concrete is the partial substitution of cement clinker with supplementary cementitious materials (SCMs). In particular, clays have a potential to fulfil this role, as they are globally abundant and can be activated using simple methods.

Determination of chemical formula of a smectite

Communications, Faculty Of Science, University of Ankara Series B Chemistry and Chemical Engineering, 2006
Smectites are dominant clay minerals in bentonites. Each of montmorillonite, beidelite, nontronite, hectorite and saponite minerals is a member of smectite group. They are valuable mineral class for industrial applications because of their high cation exchange capacities, surface area, surface reactivity, adsorptive capacity and catalytic activity ...
