Brain Gadolinium Biodistribution, Clearance, and Retention Following High-Dose Contrast-Agent Exposure in Mice: A Multimodal Study

We evaluated gadolinium biodistribution, clearance, and long-term brain retention following high-dose gadolinium-based contrast agent (GBCA) exposure in 90 mice. Macrocyclic and linear agents were assessed using particle-induced X-ray emission (PIXE) alongside complementary eleme...

Experimental study of Kohn anomalies and phonon dispersion in graphene using Raman spectroscopy

The phenomenon of Kohn anomalies (KA) in graphene is characterized by a linear phonon dispersion law at the Γ and K points of the first Brillouin zone. Until now, experimental confirmation of the KA has been based on the observation of phonon softening during inelastic x-ray scat...
