Quantification of Plutonium and Americium in Environmental Matrices Using Accelerator Mass Spectrometry

Atoms
This study focused on the measurement of anthropogenic radionuclides such as americium (Am) and plutonium (Pu) in environmental samples. Plutonium isotopes, particularly Pu239, Pu240, and Pu241, originated from nuclear weapons testing, nuclear power ...

Noble gases and nitrogen in material from asteroid Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Observation of large scissors resonance strength in actinides

, 2012
The orbital M1-scissors resonance (SR) has been measured for the first time in the quasi-continuum of actinides. Particle-gamma coincidences are recorded with deuteron and 3He induced reactions on 232Th.

Third minima in actinides - do they exist?

, 2012
We study the existence of third, hyperdeformed minima in a number of even-even Th, U and Pu nuclei using the Woods-Saxon microscopic-macroscopic model that very well reproduces first and second minima and fission barriers in actinides.

Hydrodynamic characterization of the redox chemistry of crown-encapsulated uranyl complexes

Frontiers in Nuclear Engineering
The redox properties of actinide-containing species strongly influence their reactivity, speciation, and interfacial behavior, but the experimental quantification of the electrochemical characteristics of molecular actinide complexes in nonaqueous media ...

Lead abundance in the uranium star CS 31082-001

, 2004
In a previous paper we were able to measure the abundance of uranium and thorium in the very-metal poor halo giant BPS CS 31082-001, but only obtained an upper limit for the abundance of lead (Pb).

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.

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

Spallation dominated propagation of Heavy Cosmic Rays and the Local Interstellar Medium (LISM)

, 2004
Measurements of ultra heavy nuclei at GeV/n energies in the galactic cosmic radiation address the question of the sources (nucleosynthetic s- and r-processes).
