Freshwater Aquaculture Dynamics in China’s Jianghan Plain Revealed by Multi-Source Satellite Imagery

The Jianghan Plain is one of the important freshwater aquaculture regions in China. Accurate information on the spatial distribution and spatiotemporal dynamics of aquaculture ponds is essential for regional ecological management. However, large-scale and accurate identification...

Contribution of Urbanization and Large‐Scale Warming to Temperature Increase From Pre‐Industrial Revolution Time to Recent Period in Central Beijing City

Abstract The annual mean Surface Air Temperature (SAT) observed during 1757–1762 in central Beijing was 3.1°C lower than that of the nearby Autonomous Weather Stations (AWS) in recent 6 years (2015–2020). The change was much larger than the averaged global warming of the past cen...

Prediction andControlling Factors of Macrolithotypesin Deep Coal Reservoirs

Abstract Deep coalbed methane (CBM) in the Ordos Basin is a critical resource for China’s unconventional gas supply. Accurate identification of coal macrolithotypes is essential for reservoir characterization and guiding efficient exploration and development. However, the deep co...

Nanoscale Formation,Structure, and Stability of Phosphate-IronColloids at Anoxic-Oxic Interfaces

Abstract The mobility of phosphorus (P) at anoxic–oxic interfaces is largely controlled by the formation of phosphate-iron (Fe) colloids, yet the nanoscale mechanisms underlying their formation, structure, and stability remain poorly described. Here, we systematically investigate...

Key drivers and mechanisms of user satisfaction with smart wearable medical products: a mixed-methods study

Smart wearable medical products are increasingly used in chronic disease management and health monitoring. However, negative user experiences and discontinuance remain common in real-world use, and the multidimensional drivers of user satisfaction (US) and their interaction mecha...

Unravelling governance structures and power dynamics in Tanzania's seafood sector

Purpose This study examines how governance structures and power dynamics shape value capture and inequality in Tanzania's seafood value chains across domestic, regional, and global markets. Design/methodology/approach Semi-structured interviews were administered to 232 value chai...

Effects of groundwater level decline on shallow soil water in grassland open-pit mining areas: Water vapor migration and water sources estimation

Study region The Chenqi Coalfield in the Hulunbuir grassland, a typical semi-arid grassland open-pit mining area in Inner Mongolia, China, where mining has caused severe groundwater level decline. Study focus This study adopted in situ monitoring and hydrogen-oxygen stable isotop...

Tripolyphosphate-MediatedInterfacial Electronic ReconfigurationBoosts •OH Production and Redirects Mineral EvolutionDuring FeS Oxygenation

Abstract Oxygenation of mackinawite (FeS) at redox interfaces constitutes a key biogeochemical process that generates hydroxyl radicals (•OH) and facilitates contaminant attenuation. However, the influence of common inorganic ligands such as tripolyphosphate (TPP) on interfacial...

Modeling water flooding effect on well performance in North Troyes oilfield with complex fracture networks

Due to delayed water injection, strong fracture development and insufficient pressure maintenance after long-term depletion, oil production in the North Troyes carbonate reservoir has declined year by year. Moreover, because the reservoir contains low-volatility crude oil and a c...
