Thermal stability is becoming a barrier for silica nanofluid use at high temperatures in several industrial applications including oil fields. Homoagglomeration of SiO2 nanoparticles (NPs), which leads to premature sedimentation large NP clusters, one the reasons loss thermal stability. However, this can be improved by incorporating thermally conductive co-stabilizer, not only reduces homoagglomeration SiO2–SiO2 NPs but also improves their rheological properties. Thus, study reports titania...
Freeze drying and re-dispersibility of oil-in-water (o/w) emulsions is important from the perspective storage, transportation usability. A set stable re-dispersible o/w using polyacryloyl hydrazide (PAHz) capped Ag nanoparticles (NP) as stabilizer reported in which NP size (Davg) PAHz concentration collectively controlled stability emulsion system. O/w prepared different concentrations (0.05-0.25 g mL-1) sizes NPs (10-25 nm) were analyzed by DLS, IFT, contact angle, SEM, rheological studies....
The utility of a Pickering emulsion (PEm) under saline conditions is strongly dependent on the stability in presence different salt concentrations. In this study, we have evaluated effect NaCl and temperature polyacryloyl hydrazide (PAHz)-Ag nanocomposite (NC) based PEm utilizing ocular observation, an optical microscope with thermal stage, TGA, DLS, electrical conductivity, rheological studies at temperatures. creaming concentrations range 0.5 to 5.0 wt% was by adding amounts PAHz-Ag NC...
This work aims to explore the use of stable graphene oxide (GO) dispersions for enhanced carbon capture and oil recovery. The objective study was novel GO effective utilization. Initially, particles were synthesized via modified Hummers method dispersed in a 1000 ppm PAM solution. These solutions (0.1 0.3 wt% GO) observed visually using particle size analyzer which they did not show any instability agglomeration 28 days. Given their superior stability, then used CO2 solvation amount solvated...
