The development of measurement methodologies to detect and monitor nuclear-relevant
materials remains a consistent and significant interest across the nuclear energy …

Studies related to U gas-phase oxidation through plasma-and thermo-chemistry are
important for many fields, including environmental monitoring, forensic analysis, debris …

The review mainly deals with two topics that became important in applications of laser-
induced breakdown spectroscopy (LIBS) in recent years: the emission of halogen-and rare …

Nuclear security is one of the defining challenges of our time. Nuclear threats range from
deliberate dispersal of radioactive material to contaminate the vital infrastructure to diversion …

Improving technologies related to the wide area environmental sampling of nuclear

We investigate the oxidation of uranium (U) species, the physical conditions leading to
uranium monoxide (UO) formation and the interplay between plume hydrodynamics and …

Ultrafast laser ablation coupled with optical emission spectroscopy is currently under
development for standoff detection of elements and their isotopes for a wide range of …

In order to model the fate and transport of particles following a nuclear explosion, there must
first be an understanding of individual physical and chemical processes that affect particle …

The chemistry evolution in a laser ablation plume depends strongly on its initial physical
conditions. In this article, we investigate the impact of plasma generation conditions on the …

Gas-phase oxidation of uranium (U), plume chemistry, and the corresponding impact on
optical emission features of the U plasma are investigated. Plasmas were produced via …
