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

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 …

Rapid, in-field, and non-contact isotopic analysis of solid materials is extremely important to
a large number of applications, such as nuclear nonproliferation monitoring and forensics …

Improving technologies related to the wide area environmental sampling of nuclear
materials supports the nuclear nonproliferation mission of preventing the proliferation of …

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 …

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 …

The dynamics of expansion, thermodynamics, and chemical reactions in laser-produced
plasmas is of general interest for all laser ablation applications. This study investigates the …

Absorption spectroscopy with a xenon flash lamp source has been used to probe laser-
produced plasmas. Signatures from atomic, ionic, monoxide, monohydride, and mononitride …
