TLDR
Fullerenes with a single lanthanum atom trapped on the inside of the carbon cage were produced by laser vaporization of a graphite composite rod in a flow of argon gas at 1200 °C as discussed by the authors.Abstract:
Fullerenes with a single lanthanum atom trapped on the inside of the carbon cage were produced by laser vaporization of a lanthanum oxide/graphite composite rod in a flow of argon gas at 1200 °C. When sublimed with C_(60) and C_(70), they formed
an air-stable film containing principally LaC_(60), LaC_(70), LaC_(74), and LaC_(82). When dissolved in toluene and exposed to air,
LaC_(82) was found to be uniquely stable. Evidence was also obtained for coalescence reactions between these fullerenes at
high temperatures to form larger cages with as many as three lanthanum atoms inside. Indications have also been obtained
for the successful production of KC_(60), C_(59)B, and KC_(59)B where the boron has substituted for a carbon in the soccerball cage.
The use of the @ symbol is advocated for specifying such complex fullerenes as (K@C_(59)B).read more

Curling and closure of graphitic networks under electron-beam irradiation
TL;DR: The response of carbon soot particles and tubular graphitic structures to intense electron-beam irradiation in a high-resolution electron microscope is reported, suggesting that planar graphite may not be the most stable allotrope of carbon in systems of limited size.

Atoms in carbon cages: the structure and properties of endohedral fullerenes
TL;DR: The existence of such species is now strongly supported by a growing body of experimental evidence as discussed by the authors, and their structure and properties are beginning to be explored in milligram quantities, and their structures and properties have been explored.
