Electrokinetic Stabilization of Formation Fines Using Surface Modified Polymer Silica Nanocomposites During Low Salinity Water Flooding for Enhanced Oil Recovery

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Fines migration induced by low salinity water flooding severely impairs reservoir permeability and injectivity presenting a critical challenge in enhanced oil recovery. This study aims to synthesize and evaluate a surface‐modified polymer‐silica nanocomposite to mitigate clay mobilization and preserve the hydrodynamic capacity of porous media.

Restoring joint homeostasis: A dynamically adaptive meniscal scaffold prevents osteoarthritis by replicating native biomechanics

BMEMat, EarlyView.
This work establishes a paradigm shift from static structural mimicry to dynamic functional replication. By restoring the native “compression‐to‐tension” mechanism, the scaffold ensures robust mechanical stability and superior chondroprotection.

Effects of hybrid metal oxide nanoparticles on the tribological and emission attributes of algae‐derived biofuel in compression ignition engines

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The growing demand for sustainable fuels has accelerated the development of algae‐derived biodiesel for compression‐ignition engines. In this study, Chlorella vulgaris methyl ester (AME) exhibited physicochemical properties comparable to diesel and satisfied ASTM D6751 fuel quality requirements, making it suitable for blending.
