Analysis of Lithium Aging Using Machine Learning-Enhanced Spectroscopy Techniques.

Lithium compounds such as lithium hydride (LiH) and lithium hydroxide (LiOH) have a wide range of industrial applications, but are highly reactive in environments with HO and CO. These reactions lead to the ingrowth of secondary lithium compounds, which can alter the homogeneity and affect the application of particular lithium chemicals. This study performed an exploratory analysis of different lithium compounds using laser-induced breakdown spectroscopy (LIBS) and Raman spectroscopy.

LIBS and Raman spectroscopy in tandem with machine learning for interrogating weatherization of lithium hydride.

Lithium compounds such as lithium hydride ( ) and anhydrous lithium hydroxide ( ) have various applications in industry but are highly reactive when exposed to moisture and . These reactions create new molecular compounds that degrade applications. Environmental conditions such as temperature and moisture are examples of environmental conditions that are of interest for these reactions.

Production of Synthetic Nuclear Melt Glass.

Realistic surrogate nuclear debris is needed within the nuclear forensics community to test and validate post-detonation analysis techniques. Here we outline a novel process for producing bulk surface debris using a high temperature furnace. The material developed in this study is physically and chemically similar to trinitite (the melt glass produced by the first nuclear test).

Development of synthetic nuclear melt glass for forensic analysis.

A method for producing synthetic debris similar to the melt glass produced by nuclear surface testing is demonstrated. Melt glass from the first nuclear weapon test (commonly referred to as trinitite) is used as the benchmark for this study. These surrogates can be used to simulate a variety of scenarios and will serve as a tool for developing and validating forensic analysis methods.
