Study of actinide chemistry in saturated potassium fluoride solution [PDF]

open access: yes, 1969
Study concerning the chemistry of actinides in saturated KF solution included work with neptunium, uranium, and americium. Solubilities, absorption spectra, oxidation-reduction reactions, and solid compounds which can be produced in KF solution were ...

Multifunctional Eutectic Mixtures Enable Integrated Recovery of U, Pu, and Sr From Nuclear Waste

open access: yesAdvanced Science, EarlyView.
A novel class of multifunctional eutectic mixtures, crafted from crown ether and organophosphorus molecules, achieves highly efficient, simultaneous recovery of uranium, plutonium, and strontium from nuclear waste. The material operates via a dual “coordination‐encapsulation” mechanism within self‐assembled reverse‐micelle structures, offering a ...

Uranium Doped Gallium Nitride Epitaxial Thin Films

open access: yesAdvanced Electronic Materials, EarlyView.
Uranium was controllably added to gallium nitride using molecular beam epitaxy. The uranium atoms segregated into vertically oriented regions with higher doping levels. Concentrations up to a few percent were achieved without showing significant degradation in the crystalline quality or optical characteristics. Low electrical resistivity was maintained

Development and characterization of standard 241Am sources

open access: yesRadiation Protection and Environment
Monitoring of alpha activity is important in the nuclear facilities involved in handling of actinides. To detect their presence in routine samples, accurate and reliable estimation of alpha activity is required. This estimation is highly dependent on the

On the Convergence of the Electronic Structure Properties of the FCC Americium (001) Surface

open access: yes, 2006
Electronic and magnetic properties of the fcc Americium (001) surface have been investigated via full-potential all-electron density-functional electronic structure calculations at both scalar and fully relativistic levels. Effects of various theoretical

Actinide Chalcogenide Compounds

open access: yes, 2010
This chapter describes the preparation, structures, and physical properties of the known binary, ternary, and quaternary actinide chalcogenide compounds. In discussing structures we rely almost exclusively on X-ray or neutron diffraction results from single crystals rather than from powders.

A Comprehensive Assessment and Benchmark Study of Large Atomistic Foundation Models for Phonons

open access: yesAdvanced Intelligent Discovery, EarlyView.
We benchmark six large atomistic foundation models on 2429 crystalline materials for phonon transport properties. The rapid development of universal machine learning potentials (uMLPs) has enabled efficient, accurate predictions of diverse material properties across broad chemical spaces.
