Noble gases and nitrogen in material from asteroid Bennu

open access: yesMeteoritics &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.

Symbiosis‐associated UMAMIT transporters required for establishing efficient nitrogen fixation in Medicago truncatula

open access: yesNew Phytologist, EarlyView.
Summary To address a critical gap in understanding amino acid transport in legume–Rhizobium symbiosis, we investigated the role of symbiosis‐associated USUALLY MULTIPLE ACIDS MOVE IN AND OUT TRANSPORTERS (UMAMITs) in Medicago truncatula nodulation.

Thyroid cell irradiation by radioiodines: a new Monte Carlo electron track-structure code

open access: yesBrazilian Archives of Biology and Technology, 2007
The most significant impact of the Chernobyl accident is the increased incidence of thyroid cancer among children who were exposed to short-lived radioiodines and 131-iodine.

Nucleon pair approximation description of the low-lying structure of $^{108,109}$Te and $^{109}$I

open access: yes, 2013
The low-lying level schemes and electromagnetic transitions of $^{109}$Te, $^{109}$I, and the neighboring even-even nucleus $^{108}$Te, are calculated within the framework of the $SD$-pair approximation of the nuclear shell model.

Isotope shifts of 6s5d $^3$D-states in neutral Barium

open access: yes, 2008
Laser spectroscopy of the low lying $^1$P and $^3$D states in atomic barium has been performed. This work contributes substantially to the development of an effective laser cooling and trapping for heavy alkaline earth elements and aims in particular for

Determining Reactor Flux from Xenon-136 and Cesium-135 in Spent Fuel

open access: yes, 2012
The ability to infer the reactor flux from spent fuel or seized fissile material would enhance the tools of nuclear forensics and nuclear nonproliferation significantly.

Exploring CPP Enhanced Hypoxia Targeting: An Approach Using Radiolabeled 2‐nitroimidazole TAT Conjugate

open access: yesDrug Development Research, Volume 87, Issue 1, February 2026.
ABSTRACT Mediated by their protein transduction domain, cell‐penetrating peptides (CPPs) have been widely explored for facilitating intracellular delivery of drugs and small molecules. In this study, a radiolabeled, 2‐nitroimidazole conjugated TAT (TAT ‐ transactivator of transcription) peptide was prepared and evaluated for targeting tumor hypoxia ...
