The Size of Greater India: Estimates by Comparing the Apparent Polar Wander Paths of the Tethyan Himalaya and the Indian Craton

Abstract The northern extent of Greater India is a critical, yet highly debated, parameter for reconstructing the India‐Asia collision. Previous paleomagnetic estimates, including the fill‐the‐gap and fixed great circle approaches, yield widely varying results, spanning from ∼200...

Atmosphere‐Controlled Valence Engineering of Eu in Aluminate Crystals Enabling High‐Performance Temperature Sensing and Flexible X‐Ray Imaging

ABSTRACT Developing scintillators that simultaneously deliver high light yield, radiation stability, flexibility, and environmental sustainability remains a long‐standing challenge, while optical thermometry is further limited by narrow working ranges and insufficient sensitivity...

Study on the accumulation mechanism of natural gas hydrate controlled by sandy reservoirs in the Qiongdongnan Basin

Abstract This study investigates the formation mechanism of natural gas hydrates in the deep-water Qiongdongnan Basin, with particular emphasis on the controlling role of sandy reservoirs in the hydrate accumulation system. On the basis of geological observations of sand bodies i...

Modification strategies for Mn3O4-based cathode materials: Multi-factor synergistic design towards high-performance and sustainable energy storage

Manganese tetroxide (Mn 3 O 4 ) has attracted considerable attention as a cathode material for sustainable energy storage applications owing to its natural abundance and high theoretical capacity. However, its practical application is hindered by poor conductivity, significant vo...

Assessment of Deterioration Characteristics of Solid Waste-Based Binder-Stabilized Laterite Under Multiple Environmental Factors Based on Micro-Drilling Resistance

Solid waste-based binder-stabilized laterite is prone to progressive deterioration under multiple coupled environmental factors in practical engineering applications. Conventional compression and direct shear tests fail to accurately characterize the gradient deterioration patter...

Outer Surface Functionalized Graphene Oxide Nanofluidic Platform for Selective Detection of Insect Pheromones

Abstract Invasive insects inflict severe ecological and economic damage, creating an urgent need for rapid and early detection strategies. Here, we present a biomimetic strategy that replicates the molecular recognition principles of insect olfaction. As a proof of concept, our p...

A Spatio‐Temporal Neural Kernel Function Model for Earthquake Clustering: Bridging ETAS and Neural Point Processes

Abstract Modeling earthquake clustering in space and time is central to understanding seismicity patterns and improving forecasting. The Epidemic‐Type Aftershock Sequence (ETAS) model, grounded in the Hawkes process, has long been the standard approach for describing aftershock t...

Molecular Insights into the Effect of Nanoscale Surface Roughness on CO2 Hydrate Nucleation: Implications for Carbon Sequestration

Abstract Hydrate-based CO2 sequestration is a promising carbon storage technology, but its practical application is hindered by slow formation kinetics. Understanding the nucleation mechanism at a molecular level is crucial for optimizing this process. Herein, systematic microsec...

GLoR-forecast: state-contingent global-local text routing for financial and socio-economic time-series forecasting

Financial and socio-economic forecasting often requires information beyond numerical histories, as policy statements, news reports, institutional releases, and event descriptions may signal structural regimes or short-term shocks. Recent multimodal time-series methods incorporate...

Multi-Analytical Characterization of the Earthen Plaster and Ground Layer from the Nirvana Platform in Cave No. 47 of the Kizil Grottoes, Xinjiang, China

The Nirvana platform in Cave No. 47 of the Kizil Grottoes preserves an important example of early Buddhist earthen plaster and ground layer manufacture along the Silk Roads. This study investigated the material composition and stratigraphic sequence of its earthen plaster and gro...

Phase equilibrium simulation and optimal experimentation for the hydrothermal alkali treatment of Rb-rich microcline

The hydrothermal alkaline decomposition of Rb-rich microcline was systematically investigated using KOH and Ca(OH) 2 as combined additives. By integrating quantitative analyses of liquid-phase composition with crystallographic evolution of solid products, this study addresses thr...

Characterization of Rock Fabric and Its Influence on Water Occurrence in Tight Gas Reservoirs

Abstract After hydraulic fracturing, the flowback rates of some tight gas reservoirs are less than 50%, which seriously affects tight gas production. Regarding the fracturing fluid retention mechanism in tight gas reservoirs, it is still unclear. This research focused on the rock...

A Core-Constrained, Scale-Matched Electroacoustic Fusion Method for Gas Hydrate Saturation Estimation: A Case Study of Well GMGS5-W08

Clay-surface conduction in fine-grained, weakly consolidated marine sediments, together with the scale mismatch between core and logging observations, often causes resistivity- and acoustic-based estimates of gas hydrate saturation to diverge. For Well GMGS5-W08, we develop a cor...
