Investigation of the rheological properties of nanosilica-reinforced polyacrylamide/polyethyleneimine gels for wellbore strengthening at high reservoir temperatures
Published 2019“…The objective of this work is to investigate the effect of nanosilica sizes (8, 20, 50, and 85 nm) and concentrations (0.1–2 wt %) on the stability and viscoelastic behavior of polyacrylamide (PAM) cross-linked with polyethyleneimine (PEI) at 130 °C. …”

Role of TiO2 and carbon nanotubes on polyethylene, and effect of accelerated weathering on photo oxidation and mechanical properties
Published 2019“…Addition of CNTs had negligible effect on the tensile strength but it kept the same approximate value of the original before the accelerated weathering (e.g., 23.2 MPa for 1 wt% of CNTs). CNTs also protected the samples even with the presence of TONPs because of the absorbance and antioxidants effects. …”
