The Poshteh deposit is the first documented paleo-hydrothermal chimney-bearing volcanogenic massive sulfide (VMS) deposit in Iran. It occurs in the form of well-developed lensoid orebodies within the Eocene volcano-sedimentary sequence, and comprises

Measurement of heat capacity of superionic silver sulfide (argentite β-Ag2S) revealed that nanocrystalline argentite has a higher heat capacity than coarse-crystalline argentite. It is shown that the heat capacity of nanocrystalline substances inclu

It has been shown that the heat capacity of argentite β-Ag2S, which is nanocrystalline superionic silver sulfide, includes an additional positive contribution caused by the existence of the lower and upper bounds of the phonon spectrum because of a
