  • A History and Analysis of the WPA Exhibit of Black Art at the Fort Huachuca Mountain View Officers’ Club, 1943–1946

    Abstract: The 1943 art exhibition at the Mountain View Officers’ Club (MVOC), Fort Huachuca, Arizona should be considered one of the most significant events in the intersection of American art, military history, and segregation. Organizers of the event, entitled Exhibition of the Work of 37 Negro Artists, anticipated it would boost soldiers’ morale because Fort Huachuca was a predominately Black duty station during WWII. This report provides a brief history of Black art in the early 20th century, biographies of the artists showcased, and provides information (where known) about repositories that have originals or reproductions of the art today. The following is recommended: the General Services Administration (GSA) investigate the ownership of the pieces described in this report and if they are found to have been created under one of the New Deal art programs to add them to their inventory, further investigation be performed on the provenance and ownership of Lew Davis’s The Negro in America’s Wars mural, for the rehabilitation of the MVOC that the consulting parties agree upon the scope of the reproduction of the art, and request archival full reproductions of the pieces of art found in the collection of the Howard University Gallery of Art.

  • Comparison of the Quantitation of Heavy Metals in Soil Using Handheld LIBS, XRFS, and ICP-OES

    Abstract: Handheld laser-induced breakdown spectroscopy (LIBS) is an emerging analytical technique that shows the potential to replace X-ray fluorescence spectroscopy (XRFS) in the field characterization of soils containing heavy metals. This study explored the accuracy and precision of handheld LIBS for analyzing soils containing copper and zinc to support LIBS as a re-placement for XRFS technology in situ. Success was defined by handheld LIBS results that could be replicated across field analyzers and verified by inductively coupled plasma–optical emission spectrometry (ICP-OES). A total of 108 soil samples from eight military installations were pressed into 13 mm pellets and then analyzed by XRFS and LIBS. Handheld LIBS has a spot-size area 100-fold smaller than that of XRFS, and though it provided accurate measurements for NIST-certified reference materials, it was not able to measure unknown soils of varying soil texture with high particle size variability, regardless of sample size. Thus, soil sample particle size heterogeneity hindered the ability to provide accurate results and replicate quantitation results across LIBS and XRFS. Increasing the number of particles encountered by each shot through particle size reduction improved both field-analyzer correlation and the correlation between handheld LIBS and ICP-OES from weak (<15%) to strong (>80%).
