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

open access: yesAsia-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.

Multifunctional PVC/PVA‐ZnO Nanocomposites: Bridging Dielectric Response and Antibacterial Activity for Active Packaging Applications

open access: yesJournal of Applied Polymer Science, EarlyView.
PVC and PVA polymer blends are studied as a function of frequency at room temperature to find the composition that gives the AC conductivity. The blend that has 75% PVC and 25% PVA is chosen as the matrix. Then 10% ZnO nanoparticles are added for food packaging. The change, in conductivity is used as a sign of activity and food freshness.

On water repellency

Soft Matter, 2005
Water-repellency is a property of some materials, either natural or synthetic, which makes water hardly stick to them: drops roll very easily off these solids, and bounce back upon impacting them. Here we discuss recent advances in this field, which has been particularly lively in recent years. We first examine the physical causes for this effect. Then
