GAMMA-MRI: Towards a Novel Clinical Imaging Modality Using Long-lived Aligned Gamma Emitters

, 2023
This thesis presents a study of the production and hyperpolarization (HP) of metastable xenon radioisotopes (129mXe, 131mXe, and 133mXe referred to as mXe) and the investigation of the angular distribution of their γ radiation. The thesis is a collection

Decommissioning Cost Estimate for the Ghana Research Reactor‐1 Facility Using the CERREX‐D2 Software

Science and Technology of Nuclear Installations, Volume 2026, Issue 1, 2026.
The Ghana Research Reactor‐1 facility would certainly be decommissioned, either at the end of its life or by a decision to discontinue its operation. In planning for GHARR‐1’s eventual decommissioning, estimating the overall decommissioning cost is a major activity that needs to be undertaken to support budgeting and decision‐making for the project.

A Late Pleistocene‐Holocene Record of Tropical Monsoon Climate from Groundwater Noble Gases and Isotopes in the Leizhou Peninsula, Southern China

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Groundwater from the Leizhou Peninsula in tropical South China provides one of the first noble‐gas based paleoclimate reconstructions from the East Asian monsoon region. Radiocarbon dating establishes a robust chronology spanning the Late Pleistocene to the Holocene. Noble gas temperatures reveal a minimum glacial‐to‐Holocene warming of ∼5°C–6°

Parent body thermal metamorphism of enstatite chondrites: Disentangling the effects of shock melting

Meteoritics &Planetary Science, Volume 60, Issue 12, Page 2828-2863, December 2025.
Abstract Enstatite chondrites (ECs) formed on at least two parent bodies, EH and EL. After the accretion of the EC parent bodies, EC material was subjected to varying degrees of parent body thermal metamorphism (measured by petrologic types 3–6), due to heat released by radioactive isotope decay.

Matera: A not so ordinary H5 chondrite breccia with very low density and high porosity

Meteoritics &Planetary Science, Volume 60, Issue 9, Page 2125-2148, September 2025.
Abstract On the evening of February 14, 2023, at 17:58 UT, a fireball was detected by three cameras of the Italian PRISMA network (FRIPON network). The first samples of the Matera meteorite, collected 3 days after the fall, lay on the balcony of a private home.
