Stability of Aqueous Silica Nanoparticle Dispersions under Subsurface Conditions

Metin C.O., Nguyen Q.P., Lake L.W., The University of Texas at Austin, US

The potential application of nanotechnology has significantly advanced into the upstream oil and gas industry. However, harsh subsurface conditions such as high temperature and saline environment are generally incompatible to most commercially available engineered nanoparticles. [...]

Amorphous-Amorphous Phase Transition in Simulated Amorphous SiO2 Nanoparticle

Hoang V.V., Zung H., Institute of Technology, National University of HochiMinh City, VN

Via Molecular Dynamics simulation we found the transition from low density to high density states in an amorphous SiO2 nanoparticle under compression from 2.20 g/cm3 to 5.35 g/cm3. Simulations were done in a spherical model [...]
