“…Like in cobalt and copper, the solubility of the carbon in silver was very weak. 24 Therefore, a displacement of silver could occur during or just after condensation, and the silver atoms could exist in a graphene matrix as for a cobalt-carbon or copper-carbon case. 25 Banhart et al 26 ͑1998͒ and Abe et al 27 ͑2001͒ observed, at high temperature, a progressive shrinkage of the metallic ͑gold, cobalt, or copper͒ nanoparticle and the formation of hollow carbon spheres.…”

Using silver-carbon ambient sparks, hollow carbon nanospheres or multiwall carbon nanotubes were produced separately from carbon encapsulated silver nanoparticles ͑−1 , 400 K s −1 ͒ during relatively slow ͑−800 K s −1 ͒ or fast ͑−2 , 900 K s −1 ͒ cooling process. Different cooling processes ͑i.e., different exposures within high temperature͒ caused the formation of different carbon precipitates in the process of silver mediated graphitization: for −2 , 900 K s −1 and Ͻ−1 , 400 K s −1 , respectively, obtained tubelike and sphere ͑encapsulated and hollow͒-like carbonaceous nanostructures.

“…It is interesting to indicate that their experiments [45,46] revealed that the onion density varies with the metal grain size and type of substrate. When the deposition surface was copper, the obtained carbon onions showed diameters in the range 50 -200 nm, whereas in the case of the silver substrate, the multishell fullerenes size was smaller.…”
