On the solubility of gases in liquid casting alloys
Литьë и металлургия, 2023 It has been shown that hydrogen and oxygen atoms cannot be present in the open pores of crystal lattices of base metals of casting alloys. The solubility of gases in liquid casting alloys is a nanostructured process.

Casting and Casteing Indian Diplomacy
Diplomatica, 2023 Abstract In this essay, I look at a curious intersection – the emergence of Indian diplomacy in the interwar era and the end of indentured labor. A genealogical reading suggests that Indian diplomacy takes “birth” primarily to articulate the political and civic rights of the new, seemingly upper caste Indian, in contrast to the lower caste “coolie” of ...
