DEFINITION

Classification: 424/9.32

Particle containing a transition, actinide or lanthanide metal (e.g., hollow or solid particle, granule, etc.):

(under subclass 9.3) Subject matter wherein the agent includes particulate matter (e.g., hollow or solid particle, granule, etc.) which contains a transition, actinide or lanthanide metal (Atomic Numbers 21 through 30, 39 through 48, 57 through 80, and 89 through 106, inclusive).

(1) Note. The particulate matter may be organic, inorganic, or a combination thereof and may be hollow, solid, or aggregates of molecules which are not covalently bound. It may be in the form of granules, microspheres, coated metal cores, metal oxide crystals, etc.

(2) Note. The metals included under transition, actinide, or lanthanide metals are Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, Ac, Th, Pa, U, Np, Pu, Am, Cm, Bk, Cf, Es, Fm, Md, No, Lr, Unq, Unp, and Unh.
