Multifractal Evolution Characteristics of Multiscale Fracture-Pore Structures in Coal under CO2 Phase-Transition Fracturing

Abstract To deeply analyze the multifractal evolutionary characteristics of multiscale fracture-pore structures in coal subjected to CO2 phase transition fracturing (CO2–PTF), CO2–PTF experiments on coal samples were carried out in this study. Multiple multiscale fracture-pore ch...

Differentiating W and W–Sb mineralization in the Xuefeng Uplift, South China: An integrated study of scheelite geochemistry

The Xuefeng Uplift Belt in Hunan Province, South China, represents a transitional metallogenic domain between the Nanling Region and Jiangnan Orogen, hosting a series of Au–Sb–W polymetallic deposits formed under contrasting metamorphic and magmatic-hydrothermal regimes. To eluci...

Salt Dissolution–Induced Permeability Enhancement and Its Implications for Improved Oil Recovery During Waterflooding in Saline Lacustrine Carbonate Reservoirs

Waterflooding in saline lacustrine carbonate reservoirs frequently induces dissolution of soluble salt minerals, a process that substantially alters pore architecture and transport properties. However, the quantitative relationship between salt dissolution, permeability evolution...

A 3D Finite-Element Workflow for Mapping Earthquake Nucleation Tendency Under Tectonic Loading in Embedded Frictional Fault Systems

Abstract Dynamic-rupture simulations commonly prescribe rupture initiation, which complicates assessment of where instability would preferentially localize for a given fault geometry and tectonic loading. We present a 3D finite-element workflow that maps relative nucleation tende...

Evaluation of the Rb/Sr ratio as an indicator of chemical weathering: a case study from five sedimentary sections in Northeast China

Chemical weathering plays a pivotal role in the Earth's surface material cycle and global climate regulation. It not only facilitates the reconstruction of palaeoclimate characteristics but also provides essential insights into Earth's evolutionary history. The Rb/Sr ratio has be...

Nanopipette Sensing of APE1 Activity via Enzymatic Recycling and DNA Tetrahedron−Streptavidin Reporting: Profiling in Cancer Diagnostics, Oxidative Stress, and Cell Cycle

Abstract Apurinic/apyrimidinic endonuclease 1 (APE1) is a clinical biomarker whose small molecular size hinders direct detection by conventional nanopores (30 nm). Here, we report a nanopipette platform integrating APE1-driven enzymatic recycling amplification with DNA tetrahedro...

An ATP7A‐Mediated Endogenous Regulation Bio‐Clay Enzyme Enables Self‐Amplified Copper Accumulation for Immunogenic Pyrop

ABSTRACT Tumor cells maintain abnormal metabolism to support their rapid proliferation, which often compromises the therapeutic outcomes, including pyroptosis. Inhibiting the copper transporter ATPase (ATP7A) effectively disrupts this metabolic balance, yet current exogenous ATP7...

Seismo-ripples

Earthquake prediction has long been considered one of the greatest challenges in the global scientific community due to the complex and uncertain nature of seismogenic processes, along with the prevailing consensus that earthquakes are inherently unpredictable. Here, we present a...

Moral courage in nursing students before internship: A network analysis

Background Moral courage helps nursing students respond to ethically difficult situations, yet little is known about how its dimensions relate to ethical sensitivity, professional identity, and emotional intelligence at the dimension level. Research objective This study examined...

Modulation of Mechanical Quenching Properties and Analysis of the Mechano‐Optical Conversion Mechanism in ZnS

ABSTRACT Mechano‐optical responsive materials exhibit changes in luminescence intensity upon mechanical stimulation, demonstrating efficient force‐to‐optical conversion characteristics. These materials hold broad application prospects in areas such as stress sensors, flexible wea...

Structure, Biostratigraphy, and Numerical Modelling of the Nizampur Basin (Pakistan): Implications for Deformation in the Himalayan Fold‐Thrust Belt

ABSTRACT The Nizampur Basin in northern Pakistan preserves a structurally important segment of the Himalayan fold‐thrust belt between the Attock‐Cherat Range (ACR) and the Kalachitta Range. Its architecture records interaction among the Hissartang Fault, the Main Boundary Thrust...

An Efficient Parcel-Center Sampling Strategy for Parcel-Scale Crop Classification Using Multiresolution Remote Sensing

Parcel-scale crop classification is fundamental to agricultural remote sensing and precision agriculture. The integration of detailed parcel information with medium-spatial-resolution remote sensing data has become an important technical approach to parcel-scale crop classificati...

Maturation of an early Paleozoic continental arc in the Central Asian Orogenic Belt: Petrogenesis of Silurian granitoids in northern West Junggar, NW China

Transformation of basaltic intra-oceanic arcs to mature continental arcs is responsible for considerable Phanerozoic juvenile crustal growth in the Central Asian Orogenic Belt (CAOB), which is the largest accretionary orogenic belt in the world. Controversy has long surrounded th...

Calcination-induced five-coordinated Al sites on montmorillonite as anchoring points for Ru nanoparticles toward enhanced alkaline hydrogen electrocatalysis

Montmorillonite (MMT) is a promising catalyst support due to its two-dimensional layered structure and abundant surface groups. However, aluminum (Al) species in MMT predominantly exist as coordinatively saturated Al VI , lacking active anchoring sites. Herein, a calcination-indu...

Tracing Shale-Gas Migration in Complex Tectonic Settings: Evidence from Carbon-Isotope Fractionation Patterns

Abstract Late-stage tectonic deformation strongly influences shale-gas preservation and redistribution, but conventional methods rarely resolve gas-migration pathways and directions. Here, we test whether the direction of spatial carbon-isotope gradients can indicate the dominant...
