| 释义 | fullerene noun[ C ] chemistry specializeduk /ˈfʊləriːn/ us /ˈfʊlɚiːn/ any of several carbon compounds with molecules arranged in a round, hollow shape富勒烯 Chemicals, chemical compounds & gases acetic acid acetone acrolein acrylamide activated charcoal adenine agglomerate ethyl alcohol H2O HCFC HFC hyaluronic acid hydrochloric acid hydrochlorofluorocarbon laughing gas limescale metho meths oxyacetylene tartaric acid Examples of fullerenefullerene We assume here that algae provided the carbon for the fullerenes at the three locations of interest. At three sites of such fullerene discoveries the building blocks for these large molecules may have come from algal remains. A biological origin with formation in the solid state is proposed here for certain terrestrial fullerenes but with considerable trepidation because it entails formidable hurdles. These are interesting results, but they do not involve fullerene formation under natural conditions, and certainly not in the solid state. In both cases curved graphene sheets can be observed together with onion-like particles and defective structures which we have defined fullerene-like structures. These fullerene occurrences have long been a conundrum. The fullerene-like structures in carbon dust may be responsible for instance for the formation of molecular hydrogen from atomic hydrogen by an enhanced surface chemistry mechanism. Individual gadolinium atoms have been isolated by encapsulating them into fullerene molecules and visualized with transmission electron microscope.

In other words, although the carbon atoms in fullerene are all conjugated the superstructure is not a super aromatic compound.

In addition, it is used as a solvent for carbon nanomaterials, including nanotubes and fullerenes, and it can also be used as a fullerene indicator.
