Gadolinium oxide (Gd2O3) nanoparticles (GNPs) are applied in industrial products, for example, additives, optical glass, and catalysis. There are various suggestions of metal nanoparticles paradigm but the underlying basic mechanism about the toxicity of metal nanoparticles, for example GNPs, remains unclear. This experiment was done to measure the effective toxicity of GNPs (10, 25, 50, and 10...

This study describes the use of a composite nitrate salt solution as a precursor to synthesize CeO2 and Gd2O3-doped CeO2 (GDC) nanoparticles (NPs) using an atmospheric pressure plasma jet (APPJ). The microstructures of CeO2 and GDC NPs were found to be cubical and spherical shaped nanocrystallites with average particle sizes of 10.5 and 6.7 nm, respectively. Reactive oxygen species, detected by...

Abstract Gadolinium-based contrast agents (GdCAs) have been the most frequently used T 1 -weighted magnetic resonance imaging (MRI) for decades. However, they serious disadvantages such as low longitudinal relaxivity value ( r ) and high dose associated-nephrotoxicity that restrict their wide applications. These emphasize need an ideal stable biocompatible CA with enhancement performance. Here,...

Single-crystal Gd2O3 films were grown epitaxially on GaAs~100! substrate. From the single-crystal momentum space analysis on four different samples, 185, 45, 25, and 18 Å thick, a Mn2O3 isomorphous cubic structure is identified. The Gd2O3 film aligns its twofold ~110! axis with the fourfold ~100! surface normal of the substrate, while aligning its @001# and @ 1̄10# axes with the @011# and @011̄# ...
