Tracking Injected Fluids: A Seismic Contrast Agent Breakthrough

A new class of acoustically active contrast agents holds promise for monitoring, mapping, and tracking fluids injected into the subsurface

February 2019

Researchers at PNNL are developing a new class of acoustically active nanomaterials designed to improve the high-resolution tracking of exploratory fluids injected into the subsurface. Once deployed in the field as stable injectable liquid, the new acoustic metamaterials could disrupt current technologies and improve the way subsurface geophysical monitoring and mapping is done.

Plutonium Experiment Opens New Research Possibilities

PNNL researchers identify and use a safe approach to access unique instrumentation in a non-radiological facility

January 2019

Researchers used novel methods to safely create and analyze plutonium samples. The approaches could prove influential in future studies of the radioactive material, improving fundamental knowledge and perhaps benefitting research in legacy waste, national security and nuclear fuels.
