Static and Dynamic Properties of the Electrical Double Layer Near Amorphous Silica: Relevance for Device Design

Shi B., Shin Y.K., Zhang H., Hassanali A., Shin Y.K., Knight C., Singer S.J., Ohio State University, US

Amorphous silica (“glass”) is commonly used to fabricate micro- and nano-fluidic devices. Using an atomistic model, we have studied the static and dynamic properties of the electrical double layer near the water/amorphous silica interface. The [...]

Atomistic Simulations of Biomolecules at the Water‐Amorphous Silica Interface: Application to Peptides and DNA Oligomers

Shi B., Shin Y.K., Shin Y.K., Hassanali A., Singer S.J., Ohio State University, US

Realistic modeling of biomolecules near amorphous silica (“glass”), a material commonly used for biomedical device fabrication, is required for device design and evaluation. Our potential model, based on ab initio quantum chemical calculations, is designed [...]

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 [...]

Simulation of Porous Si and SiOx Layer Growth

Burlakov V.M., Sutton A.P., Briggs G.A.D., Tsukahara Y., University of Oxford, UK

Monte Carlo simulation of deposition of amorphous SiOx layer on a polymer surface is reported. The model developed is based on the network properties of silica and takes into account dangling bonds arising during the [...]
