Gadolinium (Gd) Nanoparticles - Properties, Applications

Nanomaterials are gaining in popularity as they can be applied across a wide range of high-tech industries and advanced technologies due to their excellent catalytic, optical, magnetic, and electronic properties.

Gadolinium is a Block F, Period 6 element. It is found in minerals such as monazite and bastnasite. It is malleable and ductile rare-earth metal. The morphology of these particles is spherical, and they appear as a black powder.

Gadolinium nanoparticles are graded as toxic, and when in contact with water, they release flammable gases which can ignite spontaneously.
