Data‐Driven Insights into Rare Earth Mineralization: Machine Learning Applications Using Functional Material Synthesis Data

Advanced Intelligent Systems, EarlyView.
Hydrothermal synthesis records for rare‐earth compounds are repurposed to learn mineralization rules. An extreme gradient boosting model ingests precursors, additives, and engineered descriptors to predict product phases, crystallization temperature, and pH. Feature importance indicates dominant thermodynamic control with kinetic modulation, suggesting

Enhanced Oxidase‐Like Activity of Ag‐Decorated V2O5 Hollow Microspheres for the Colorimetric Detection of Mercury (II) Ions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this work, we report the synthesis of a novel Ag‐decorated V2O5 nanozyme with intrinsic oxidase‐like activity for the colorimetric detection of Hg2+ ions. The Ag/V2O5 hollow microspheres were synthesized via a simple hydrothermal method followed by Ag nanoparticle decoration and thoroughly characterized by XRD, XPS, SEM, TEM, HRTEM, and EDX.

Mechanism of Hydrogen Sulfide Generation and Prevention Strategies in Oil and Gas Fields: A Case Study of the Sickle Bay Operation Area

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To address the persistent exceedance of hydrogen sulfide (H2S) concentrations and the limited effectiveness of existing treatments in the Sickle Bay oil production area, this study deeply analyzes the mechanism of H2S generation in the Sickle Bay oil production area and proposes targeted prevention and control strategies. The results show that
