The End Of Nucleosynthesis: Production Of Lead And Thorium In The Early Galaxy [PDF]

, 2009
We examine the Pb and Th abundances in 27 metal-poor stars (-3.1 56) enrichment was produced only by the rapid (r-) nucleosynthesis process. New abundances are derived from Hubble Space Telescope/Space Telescope Imaging Spectrograph, Keck/High ...

Orbital-based Scenario for Magnetic Structure of Neptunium Compounds

, 2004
In order to understand a crucial role of orbital degree of freedom in the magnetic structure of recently synthesized neptunium compounds NpTGa_5 (T=Fe, Co, and Ni), we propose to discuss the magnetic phase of an effective two-orbital model, which has ...

Photoelectron spectroscopy of NpPd3 and PuPd3 [PDF]

, 2008
We present the results of x-ray and ultraviolet photoelectron spectroscopy of NpPd3 and PuPd3. The spectra indicate that for both compounds, the 5f electrons are well localized on the actinide sites.

Comparative Study of Complexes of Rare Earths and Actinides with 2,6-Bis(1,2,4-triazin-3-yl)pyridine

Inorganics, 2019
Complexes of group III metals (rare earth and actinides) with 2,6-bis(5,6-dipropyl-1,2,4-triazin-3-yl)pyridine (BTP) have been investigated by computational (DFT) and, in limited cases, by experimental (FT-IR, X-ray) techniques with the goal of ...

Inducing Ferromagnetism by Structural Engineering in a Strongly Spin‐Orbit Coupled Oxide

Advanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
ABSTRACT Magnetic materials with strong spin‐orbit coupling (SOC) are essential for the advancement of spin‐orbitronic devices, as they enable efficient spin‐charge conversion, complex magnetic structures, spin‐valley physics, topological phases and other exotic phenomena.

An Actinide-boost Star Discovered in the Gaia-Sausage-Enceladus

The Astrophysical Journal Letters
We report the discovery of an actinide-boost, very metal-poor ( $\left[{\rm{Fe}}/{\rm{H}}\right]=-2.38$ ), r -process-enhanced ( $\left[{\rm{Eu}}/{\rm{Fe}}\right]=0.80$ ) star, LAMOST J0804+5740, within the Gaia-Sausage-Enceladus (GSE). Based on the high-

Application of the S=1 underscreened Anderson lattice model to Kondo uranium and neptunium compounds

, 2010
Magnetic properties of uranium and neptunium compounds showing the coexistence of Kondo screening effect and ferromagnetic order are investigated within the Anderson lattice Hamiltonian with a two-fold degenerate $f$-level in each site, corresponding to $

Evaluation of Iron‐Phosphate Glass–Ceramic Waste Form for Electrorefiner Salt Waste Simulant Dechlorinated With Phosphoric Acid

International Journal of Ceramic Engineering &Science, Volume 8, Issue 3, May 2026.
This work investigates the formation of high‐alkali‐iron‐phosphate glass–ceramic waste forms made from the dechlorinated product of a phosphoric acid‐based process. The salt simulant is mixed with H3PO4 to form a slurry, heated, and then the dechlorinated product is vitrified with glass formers to obtain the final waste form. ABSTRACT The importance of
