recommendations! Published in 2019 at "Magnetic Resonance in Medicine"

DOI: 10.1002/mrm.27658

Abstract: Multi‐exponential relaxometry is a powerful tool for characterizing tissue, but generally requires high image signal‐to‐noise ratio (SNR). This work evaluates the use of principal‐component‐analysis (PCA) denoising to mitigate these SNR demands and improve the precision… read more here.

DOI: 10.1016/j.jallcom.2020.158187

Abstract: Abstract Magnetic nanoparticles of e-Fe1.76Ga0.24O3 were prepared by thermal treatment of a mesoporous silica matrix impregnated with nitrates. The chosen Ga-doping enhanced magnetization and suppressed the low-temperature spin-reorientation transition typical for e-Fe2O3. Despite the small… read more here.
