Nanostructures of rare-earth metals in the coals of the shubarkol deposit

Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2022
The rare metals of the Shubarkol coal deposit have a surface layer thickness of about 3 nm, i.e. are nanostructures. The thickness of the surface layer of the coal itself is of about 0,2 µm, i.e. it is a mesostructure.

Thickness of the surface layer, surface energy and atomic volume of the element [PDF]

Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2018
The thickness of the surface layer of an atomically pure metal, which turned out to be equal to 5-6 nm, was calculated in this work. It is shown that the thickness of the surface layer is determined by one parameter – the atomic volume of a chemical ...
