Actinide Nanoparticles: Revising Early Developments and Recent Insights from High‐Energy‐Resolution Fluorescence‐Detected X‐Ray Absorption Near Edge Structure and Synchrotron Techniques

Small Science, EarlyView.
Actinide nanoparticles are relevant to nuclear waste storage, environmental safety, advanced nuclear fuel engineering, and fundamental science. Herein, this review traces the early developments of the field and the recent progress enabled by the use of high‐energy‐resolution fluorescence‐detected X‐ray absorption near edge structure in synergy with ...

Indigenous Students Enacting and Advancing Sovereignty in Higher Education: Relationships, Relevance, Reciprocity, Responsibility, Representation, and Respect Along STEMM Pathways

Journal of Research in Science Teaching, EarlyView.
ABSTRACT Indigenous students are the experts of their own experiences, and in this paper, we center the narratives of 17 Indigenous students pursuing STEMM (science, technology, engineering, mathematics, medicine) pathways in colleges and universities across the western United States to better understand the affirming and challenging elements that ...

Iowa Population Exposures to Metals and Metalloids in Well Water

Environmental Toxicology, EarlyView.
ABSTRACT Previous Iowa studies suggest low levels and chronic arsenic exposures are associated with prostate cancer. The rural Iowa population heavily relies on private wells for drinking water resources and thus is vulnerable to contaminants such as heavy metals found in well water.

Formation of Uranium Pinacolate from the Reductive Coupling of Acetone

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Uranium(III) cyclopentadienyl complexes are shown to react with acetone in a pinacol coupling, forming uranium pinacolate complexes. Single crystals obtained from the reaction are the first direct structural proof of the previously proposed metallapinacolate intermediate. 1,2‐Diols are elemental building blocks in organic synthesis.

The source processes affect the initial chalcophile element fertility of arc magmas

Communications Earth & Environment
The chalcophile element fertility of arc magmas that modulates the enrichment of gold in porphyry copper deposits is negatively correlated with magma differentiation depth, which was attributed to sulfide saturation during magmatic evolution.

Gaia: segmented germanium detector for high‐energy X‐ray fluorescence and spectroscopic imaging

Journal of Synchrotron Radiation, EarlyView.
We present Gaia, a cryogenically cooled monolithic array of 96 high‐purity germanium pixel detectors integrated with a custom low‐noise application‐specific integrated circuit and a field‐programmable gate array‐based data acquisition system. The system achieves an average energy resolution of 711 eV at 122 keV and 253 eV at 5.89 keV, and serves as the

Dispersion‐compensated Rowland spectrometer: implications for uranium VB‐RIXS

Journal of Synchrotron Radiation, EarlyView.
A valence‐band resonant inelastic X‐ray scattering instrument, operating in the tender X‐ray range, uses an incoming beam with a linear energy dispersion to reach the intrinsic resolution of the Rowland spectrometer. Such a scheme is insensitive to the incident bandwidth and therefore preserves count‐rates despite the higher resolution.The total energy
