Abstract

Textured particles and methods of making the same. A textured particle includes an inner core and a spherical solid outer shell including an outer surface. The inner core is inside the outer shell. The outer surface includes a first tier texture including a first metal, wherein the first metal is greater than 50 atomic % of a total atomic content of all metals in the first tier texture; a second tier texture including the second metal, wherein the second metal is greater than 50 atomic % of a total atomic content of all metals in the second tier texture; and a third tier texture including the third metal, wherein the third metal is greater than 50 atomic % of a total atomic content of all metals in the third tier texture. The first metal, second metal, and third metals are different metals.
