Title: Studies of hollow carbon nanospheres and grain boundary phase transitions in metals as examples of plasma material science

Results are presented from studies of the material of hollow carbon nanospheres (nanocapsules) that form in tokamaks as a result of plasma interaction with the chamber wall and are similar in structure to meteorite onions. The possibility is demonstrated of studying the material properties in the grain boundary phase transitions in solid materials (metals) by using the plasma-stimulated permeability for hydrogen. The term 'plasma material science' is proposed for such material studies.
