Surface and grain-boundary excess of ZnO-doped SnO2 nanopowders by the selective lixiviation method

What is it about?

The paper is about the spontaneous modification in the interfaces composition by segregation which controls the nanoparticles size. The interface (surface and grain boundary) segregation was quantitatively determined by the selective lixiviation method demonstrating the high segregation in the grain boundaries and surface.

Why is it important?

The most important contribution was to demonstrate and quantifies the segregation in both interfaces and the direct relationship with the nanoparticle size.
