Nanosilica-Based Sealing of Wellbore Cement Leaks in Geological CO₂ Storage: A Geotechnical and Geochemical Approach

This study demonstrates that a sodium-induced nanosilica gel serves as an effective, thermally stable sealant for remediation of CO₂ leaks in fractured wellbore cement, with sealing performance significantly enhanced by higher nanosilica concentrations and diminished by wider fracture widths.

Coastal Adaptation in Small Island Developing States: A Systematic Literature Review of Academic Research

This systematic literature review of 60 studies reveals that coastal adaptation research in Small Island Developing States is geographically and thematically concentrated, with effectiveness increasingly framed through process quality and social legitimacy rather than explicit outcomes, suggesting that future adaptation efforts should prioritize multi-criteria approaches that negotiate trade-offs and sequence interventions over seeking a single optimal strategy.

Life cycle assessment of antibiotic wastewater treatment technologies: A dual-endpoint framework with fluoroquinolone ecotoxicity

This study employs a dual-endpoint life cycle assessment framework to compare four antibiotic wastewater treatment technologies, revealing that while constructed wetlands have the lowest global warming potential and cost per gram of fluoroquinolone removed, advanced oxidation processes incur the highest environmental costs despite their efficacy.

Seasonal Variability of Soil Radon Exhalation Under Climate Forcing: An Example of Humid Subtropical Highland Climate

This paper presents a transient, climate-forced 1-D soil model that resolves seasonal soil radon exhalation in humid subtropical highland climates, revealing a bimodal flux pattern driven primarily by moisture's competing effects on diffusion and emanation, with moisture contributing more to variance than temperature.

A Critical Review of Existing Probability of Success (PoS) Methods in Geothermal Exploration and Introduction of Demand Oriented, Geologically Conditioned PoS (DOGC-PoS) for Pre-Drilling Assessment: Spatial DOGC-PoS Mapping of the Rhaetian Deltaic System

This paper critiques traditional geothermal Probability of Success (PoS) methods for relying on static geological thresholds rather than project-specific performance needs, and introduces the Demand Oriented, Geologically Conditioned PoS (DOGC-PoS) framework, which defines success as the probability of meeting explicit thermal targets by integrating geological uncertainty with performance modeling, as demonstrated through a spatial application to the Rhaetian Deltaic System.

Integrating climate change into pattern-based modelling of agricultural and forest land dynamics in Romania

This study integrates three climate change scenarios into a pattern-based CLUE-s model to project that while Romania's agricultural and forest land use will remain largely stable by 2050, localized shifts driven primarily by temperature changes in mountainous regions necessitate adaptive management strategies.

Assessing the Rainfall Distribution and Its Precipitation Concentration Index (PCI) for Crop Production in Northern Guinea and Sudan Savannas of Nigeria

This study analyzes 31 years of rainfall data (1994–2024) from Nigeria's Northern Guinea and Sudan Savannas, revealing a trend of decreasing annual rainfall and increasing irregularity in distribution, which necessitates a shift toward short-duration crops or irrigation to sustain agricultural productivity.

Characteristics of Crude Oil Mobilization and Displacement Mechanisms in Low-Permeability Conglomeratic Sandstone Reservoirs under Different Development Modes: An NMR-Based Study

This study utilizes NMR technology to demonstrate that while water flooding effectively displaces oil from larger pores in ultra-low-permeability conglomeratic sandstone reservoirs, supercritical CO₂ flooding significantly enhances recovery from smaller pores through molecular diffusion and viscosity reduction, suggesting a complementary sequential development strategy for maximizing oil mobilization.

INRA-Transformer: A Multi-Scale Hybrid Vision Transformer for Precise Seismic Deformation Mapping of the 6.1 Mw Sındırgı Earthquake

This study introduces INRA-Transformer, a novel multi-scale hybrid Vision Transformer that integrates Inception-based patch embedding and depthwise-convolutional feed-forward networks to achieve highly accurate and interpretable mapping of surface deformation from the 6.1 Mw Sındırgı earthquake by effectively distinguishing subtle seismic signals from complex DInSAR noise.
