Kaolinite/Montmorillonite Resembles Beidellite

Clays and Clay Minerals, 1994
AbstractA number of smectitic samples from Almeria (SE Spain) were studied by chemical analysis, DTA, TG, XRD (oriented aggregates with ethylene glycol treatment and Greene-Kelly test), FTIR and MAS NMR. Chemically they resembled a beidellite-montmorillonite series, displaying DTA/TG characteristics already quoted in the literature in beidellite ...

The United States Magnetotelluric Array and the National Impedance Map

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract The United States Magnetotelluric Array (USMTArray) data set, collected in the years 2006–2024, consists of more than 1,700 long‐period magnetotelluric stations covering the entirety of the contiguous United States on a quasi‐regular 70 km grid.

THE EFFECT OF KAOLINITE ON CALCIUM CARBONATE WATER-BASED DRILLING FLUID

Rudarsko-geološko-naftni Zbornik
This study evaluates the effect of kaolinite addition on calcium carbonate water-based drilling fluids (WBM) through systematic laboratory testing. Kaolinite was incorporated at concentrations of 42.8 kg/m³ (15 lb/bbl), 85.6 kg/m³ (30 lb/bbl), and 128.4 ...

Pore Size and Wettability Control Dissolution Trapping Regimes of CO2 in Nano Porous Media

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We simulate supercritical carbon dioxide (scCO2 ${\text{scCO}}_{2}$) dissolution in water in nano/submicron pore‐throats (14.3–21.5 nm) using a multi‐component, multiphase pseudopotential lattice Boltzmann model closed by a Peng–Robinson equation of state.

Distal Marine Mercury Signals in Peak Late Paleozoic Ice Age: Implications for Aeolian Versus Volcanic Inputs

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract An investigation of the relationships among large igneous province (LIP), carbon cycling, and climate change is central to understanding Earth system. During Glacial III, the most intense phase of Late Paleozoic Ice Age, the influence of coeval LIP on the carbon cycle and climate remains debated.

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates

Land Degradation &Development, Volume 37, Issue 8, Page 3169-3181, 15 May 2026.
ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...

On the Role of the Interlayer Interactions in Atomistic Simulations of Kaolinite Clay

Molecules
A systematic simulation study was performed to investigate the interlayer interactions in a 1:1 layered phyllosilicate clay, kaolinite. Atomistic simulations with classical realistic force fields (INTERFACE and ClayFF) were used to examine the influence ...

Packaging of Macroscopic Material Payloads: Needs, Challenges, Concepts, and Future Directions

Advanced Engineering Materials, Volume 28, Issue 9, 6 May 2026.
This review introduces a unified framework that decomposes any macroscopic packaging system into the payload, packaging material, and packaging strategy and combines them into a conceptual packaging equation: packaging strategy = payload + packaging material.

Boric Acid Post‐Modified [Al]ZSM‐5 Zeolites: Properties, Acidity, and Ethanol/Ethene Conversion

Chemistry – A European Journal, Volume 32, Issue 17, 5 May 2026.
The modification of MFI zeolites with boric acid leads to the formation of framework boron, unstable surface species, and unbound deposits. Relevant BAS for catalysis and access to pores are strongly reduced. The boric acid is removed upon converting C1 or C2 alcohols and ethene. ABSTRACT The effect of boric acid post‐modification on [Al]ZSM‐5 zeolites
