A Peridynamic Framework for Modeling Progressive Failure in Porous Sandstone Indentation

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT A state‐based peridynamic model is proposed to simulate the failure mechanisms in porous rocks, using Bentheim sandstone as a specific example. Experimental observations reveal a transition from brittle to ductile failure under increasing triaxial compression. This behavior is attributed to pore compaction. The peridynamic model is enhanced to

Impact of Al3+ Concentration on Montmorillonite Sedimentation: Insights Into Particle Size Behavior

ChemistryOpen, EarlyView.
The current research essentially focuses on the coagulation and sedimentation characteristics of particles with two distinct particle‐size compositions. The DLVO theory confirms that under the influence of aluminum ions, the coarse and fine particle sampleS of montmorillonite essentially possess the effect of eliminating or weakening the “barrier ...

Impact of Organic and Inorganic Fillers on the Performance of Ternary Biodegradable Poly(Butylene Succinate‐Co‐Butylene Adipate), Poly(Butylene Adipate‐Co‐Terephthalate), and Poly(3‐Hydroxybutyrate‐Co‐3‐Hydroxyvalerate) Blends

Polymer Composites, EarlyView.
Development of a ternary blend composite based on PBAT/PBSA/PHVB with improved mechanical properties. ABSTRACT This study explores a ternary biodegradable blend of bio‐based poly(butylene succinate‐co‐adipate) (bio‐PBSA), poly(butylene adipate terephthalate) (PBAT), and poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV).

A Comprehensive Review of Adsorbents for Rare Earth Separation: Design, Synthesis, Adsorption Performance, and Mechanisms

Rare Metals, EarlyView.
ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

Enhancing printability of 3D printed concrete by using metakaolin and silica fume

Structural Concrete, EarlyView.
Abstract This study investigates the effects of incorporating metakaolin (MK) and silica fume (SF) on the fresh and hardened properties of 3D printed concrete (3DPC). Five mix designs were prepared with MK replacement levels of 0%, 10%, 12.5%, and 15%, along with one mix containing 10% MK and 5% SF.

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.
