Sc(III) Complexes of Pyclen Derivative Ligands as Probes for Hypoxia: Synthesis, Chemical Characterization, 44Sc‐Radiolabeling, and Preclinical Assessment

open access: yesChemistry – A European Journal, Volume 31, Issue 72, December 23, 2025.
Hypoxia‐sensitive nitroimidazole‐functionalized pyclen derivatives were successfully synthesized and radiolabeled with 44Sc(III), affording stable and inert scandium complexes. Remarkable Sc(III)‐binding capabilities of the PC2A‐mono(amide) platform enabled excellent radiolabeling performance, with ≥92–99% yields and ≥99% radiochemical purity. MicroPET

The Development and Challenges of PET/MRI Dual‐Modality Imaging Probes—An Update

open access: yesJournal of Magnetic Resonance Imaging, Volume 62, Issue 5, Page 1245-1259, November 2025.
ABSTRACT The integration of Positron emission tomography (PET) with Magnetic resonance imaging (MRI) combines the functional imaging capabilities of PET with the high‐resolution anatomical detail of MRI, creating a synergistic platform for advanced diagnostic imaging and image‐guided therapies. Central to the success of this dual‐modality system is the

Petrography of phosphates in CI and CY carbonaceous chondrites

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 11, Page 2594-2622, November 2025.
Abstract Phosphate minerals are significant carriers of volatiles (e.g., OH) and halogens in chondritic material; however, their origin in most groups of carbonaceous chondrites remains poorly characterized. We have determined the abundance, morphology, texture, and composition of phosphate grains in aqueously altered CI chondrites and in hydrated and ...
