Quantification of 10B and 11B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT)

Medicinal Research Reviews, Volume 46, Issue 5, Page 1362-1389, September 2026.
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...

Exhumation History of the Sangre de Cristo Range, Colorado, From Mid‐ to Low‐Temperature Thermochronology: New Insights Into Laramide Contraction and Oligocene–Miocene Extension in the Northern Rio Grande Rift, USA

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The Sangre de Cristo Range in southern Colorado records a complex tectonic history that includes Late Cretaceous–Eocene Laramide contraction and Oligocene–Quaternary Rio Grande rift extension. We present new thermochronologic data (40Ar/39Ar, fission‐track, (U‐Th)/He) and thermal history models that provide insight into this polyphase history ...

Validation of a New Design of Tellurium Dioxide-Irradiated Target

Nuclear Engineering and Technology, 2016
Production of iodine-131 by neutron activation of tellurium in tellurium dioxide (TeO2) material requires a target that meets the safety requirements. In a radiopharmaceutical production unit, a new lid for a can was designed, which permits tight sealing

The Ames impact structure, Oklahoma: New radioisotopic constraints and implications for North American impact chronology

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2103-2139, August 2026.
Abstract The Ames impact structure (Oklahoma) is thought to have formed during the Ordovician Meteor Event, based on conodont biostratigraphy of its crater fill. Here, U–Pb zircon dates from its impact‐melt portion, conducted using secondary ion mass spectrometry and laser ablation–inductively coupled plasma–mass spectrometry (n = 37 spots), yield a ...

Direct Measurement of the Singlet Lifetime and Photoexcitation Behavior of the Boron Vacancy Center in Hexagonal Boron Nitride

Advanced Optical Materials, Volume 14, Issue 25, 3 July 2026.
Negatively charged boron vacancy defects in hexagonal boron nitride promise near‐surface quantum sensing, but their internal spin transition rates are only partly understood. This work directly measures the defect's singlet‐state lifetime, 15(3) ns, using a nanosecond rise‐time dual‐pulse photoluminescence‐recovery method, and shows that high laser ...

Carboranyl‐Curcuminoids for the Neutron Capture‐Based Treatment of Amyloid Aggregates in Alzheimer's Disease

Advanced Science, Volume 13, Issue 39, 13 July 2026.
The 10B‐enriched monocarbonyl analog of curcumin (BMAC) 10B‐9 enables site‐specific Boron Neutron Capture Therapy (BNCT) on amyloid‐β (Aβ) fibrils. Neutron irradiation induces histidine oxidation and fibril destabilization, as revealed by 1H‐NMR and FESEM analyses.
