Enhanced Rheological and Filtration Performance of Drilling Fluids Using Fe3O4/Saponin/Cu(II) Nanocomposites: Synthesis, Characterization, and Application

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Drilling fluids used in high‐performance well operations often struggle to maintain rheological stability, colloidal dispersion, and filtration control under harsh downhole conditions. This study engineered a multifunctional Fe3O4@Saponin/Cu(II) nanocomposite to address these challenges.

Thermal Expansion Coefficient of Curdlan Tripropionate Measured by Thermal Mechanical Analysis and Wide‐Angle X‐Ray Diffraction

open access: yesJournal of Applied Polymer Science, EarlyView.
This study demonstrates the thermal expansion behavior of curdlan tripropionate films using thermal mechanical analysis and synchrotron WAXD. Both amorphous and crystalline films show characteristic expansion near the glass transition, providing structural insights for designing heat‐resistant polysaccharide‐based plastics.
