Abstract

In this article, we will present the first experimental observation of nanojets formed by heating PbO-coated Pb clusters, which has been predicted theoretically by M. Moseler and U Landman. During the heating, the hot liquid ejects through the broken orifice into vacuum, and forms a condensed trail in the tadpole shape as shown in the TEM micrographs. The temperature-variable Raman spectra indicates that the nanojet formation is closely related to the heating temperature and thus essentially to the internal pressure in the coated clusters. The pressure inside the shell, which rises from the inner core's melting and its confined volume expansion and then drops after the final explosion, dominates the whole nanojetting process.
