Summary: In this study, the preferred orientation of silver plating film was analyzed using the Rietveld method and quantitative texture analysis (RM+QTA). The results showed that the exponential harmonic index can completely describe the axial texture and be used for quantitative harmonic description of electroplating. Additionally, a new dimension involving crystallite shape and size was considered in characterizing the preferred orientation.

Summary: Increasing the strain rate can shorten the response time of shale and modify its stress-strain curves. Additionally, the strength and elastic modulus of shale generally increase with increasing strain rate, and the failure mode changes from shearing failure to a combination of tensile split and shearing failure.

Summary: This study reports a fast and nondestructive method to determine the crystallographic orientation of 2D violet phosphorus nanoflakes using Raman spectroscopy. It was found that the nanoflakes have specific in-plane cleavage edges and edge alignment. The direction of the b-axis (a-axis) can be identified by measuring the intensity of the A(g) mode in the Raman spectrum, specifically the appearance or disappearance of the 491 cm(-1) peak, relative to the cleavage edge.

Summary: The crystallographic orientation of nanoparticles on the surface of solid crystalline matrix plays a crucial role in their activity, and predicting this orientation can be advantageous in materials science. This study presents a method to predict crystallographic orientation by determining structure compatibility of two crystal structures based on overlapping atoms. The compatibility of ZnS nanoparticles with tetrahedral kaolinite surface was studied and results were consistent with molecular simulations and high-resolution transmission electron microscopy analysis.

Summary: The Rietveld method combined with a recursive structure-factor calculation has been successfully applied to describe the stacking disorder of interstratified illite-smectites, with the study verifying its applicability in determining structural parameters, and the reliability of refinements increasing with the proportion of illitic layers.

Summary: Shale has anisotropy in elastic parameters and permeability coefficient in parallel and perpendicular directions to the bedding plane. A fluid-structure coupling numerical model is established to study fracture propagation during hydraulic fracturing in shale reservoirs. The results show that hydraulic fractures easily expand parallel to the bedding plane but not perpendicular to it. Stress interference along the direction of the minimum horizontal principal stress can be balanced by controlling perforation friction, leading to the balanced extension of multiple fractures. The research provides a theoretical reference for the development of shale petroleum resources.

Summary: This study investigates the effect of glass wool waste on the sintering properties of kaolinitic and illitic clays in the ceramic industry. It was found that the addition of glass wool increased compressive strength at lower temperatures, while the addition of spodumene tailings mitigated firing shrinkage at higher temperatures.

Summary: Understanding the abundance variability of clay minerals is important for land management and addressing climate change and soil fertility concerns. This study used digital soil mapping to model the abundance and spatial distribution of clay types in Darab district, southern Iran. Multiple Linear Regression and Random Forest techniques were applied to link clay types and environmental attributes obtained from satellite imagery and topographic data. The models accuracy was assessed using cross-validation and bootstrap techniques. The results showed that the Random Forest model performed better in predicting the abundance and variability of clay minerals. Topographic covariates and soil properties influenced the variations in palygorskite and kaolinite content, while only soil properties explained the spatial distribution of illite. The study provides valuable insights into the spatial variability of clay minerals in arid and semi-arid regions and highlights the importance of easily available environmental variables in predicting clay mineral abundance. Further research is recommended to include additional environmental covariates for more accurate predictions.

Summary: Through experiments, the study observed the lattice preferred orientation contributing to seismic anisotropy, indicating akimotoite is one of the dominant minerals near the subducting slabs in the lower mantle transition zone, suggesting its lattice preferred orientation may explain the observed seismic anisotropy.

Summary: This paper introduces recent advances in the synthesis of zeolites using natural clays including kaolinite, bentonite, illite, attapulgite, and diatomite. The activations of clays and the synthesis methods of zeolites are discussed, and the future development trends for clay-based zeolite are anticipated.

Summary: The sequestration of AOM in clays is important for carbon sinks in lake sediments, with recent research showing that composition of AOM influences its preservation. Illite was found to adsorb AOM more than kaolinite, with components such as humic acid-like, tyrosine-like, and tryptophan-like being identified in AOM fractionation studies. Illite was observed to be more effective in preserving AOM, as confirmed by TEM-EDS and XPS analysis.

Summary: The article discusses the importance of mica-rich rocks in the structure of the continental crust, and how roofing slates serve as an excellent benchmark for studying the relationship between rock microstructure and seismic anisotropy. The research findings highlight the significant impact that cracks, pores, and fractures have on the seismic velocities of single-foliated slates, contributing to a strong anisotropy.

Summary: The study investigated the adsorption mechanisms of CH4, CO2, and H2O molecules on various shale surfaces using density functional theory. Results showed that the Al&Mg-doped illite surface exhibited the strongest adsorption ability, with H2O having the highest adsorption capacity among the three molecules.

Summary: Shale gas, primarily methane, is currently being developed to meet global energy demands. Using Density Functional Theory (DFT) and Molecular Dynamics (MD) techniques, researchers studied methane transport in shale pores and found that methane predominantly undergoes physisorption on the interface, with stronger adsorption on the kaolinite region.

Summary: Lithium is currently mainly sourced from ore and salt lakes, but the rapid development of electric vehicles is increasing the demand for lithium. The marine black shale in the northern Guangxi area of China has a high lithium content of up to 1000 ppm. The study reveals that illite is the main carrier mineral of lithium in the shale, and the lithium-rich shale was formed under anoxic depositional conditions. These findings provide important reference material for understanding the enrichment mechanisms of lithium in surface environments.
