Description:

A laboratory testing apparatus was developed for the study of seismic body wave propagation through nanoparticles dispersed in pore fluid that is essentially saturating glass beads. First, the responses of water-saturated glass bead specimens were studied to establish baseline signatures. Then the seismic responses in the presence of engineered nanoparticles of various concentrations dispersed in the pore fluid of the specimen chamber were studied to observe variances from baseline.

Purpose/Objective:

This study was part of a larger project concerning the detection of nanoparticles used in engineered nanomaterials as they disperse throughout the environment. This study addresses the potential for seismic methods to be implemented in detecting such nanoparticles in a natural environment. A testing system was built and calibrated in air, water, and essentially saturated glass beads. Testing was then conducted for the presence of various types of nanoparticles dispersed in the pore fluid of essentially saturated glass bead specimens.
