    • There are disclosed a porous carbon material which comprises a fullerene crystal body and which has an average pore diameter of at least 100 nm that has never hitherto been realized; and a process for producing a porous carbon material which comprises subjecting a fullerene crystal body composed of at least two types of fullerenes each having a different molecular weight to an elution treatment by the use of a solvent which shows a relatively high solubility for at least one fullerene from among the fullerenes constituting the crystal body, and which shows a relatively low solubility for at least one fullerene other than the foregoing. The porous carbon material is preferably used as a carrier for corpuscular catalyst for a fuel cell and also as a base material of a modifying agent for a fuel cell and the like.

    • A production method of the present invention includes: a process of bringing a solution 12 and a second solvent 13 into contact with each other so that a liquid-liquid interface 14 is formed therebetween, where the solution 12 includes a first solvent containing a benzene derivative (A) whose content is at least 50 wt. % and fullerene dissolved in the first solvent, and the second solvent 13 has a lower solubility of the fullerene than that of the first solvent; and a process of allowing the solution 12 and the second solvent 13 to be mixed together through counter diffusion of the solution 12 and the second solvent 13 to deposit crystals of the fullerene. The benzene derivative (A) is at least one benzene derivative selected from the group consisting of a benzene derivative in which at least two hydrogen atoms of a benzene ring have been substituted, halogenated benzene, and alkoxybenzene.

    • A compositional range for a mother glass composition for graded index lenses which has a desired refractive index and is less apt to be devitrified and to develop cracks upon ion exchange was obtained by incorporating at least a given amount of one or more ingredients which are selected from oxides of metal elements ranging from yttrium, atomic number 39, to tantalum, atomic number 73, and which are less apt to cause glass coloration into a glass based on SiO2—TiO2—Li2O—Na2O and containing no lead oxide. In particular, a compositional range in which a large angular aperture is obtained and devitrification is less apt to occur was obtained by incorporating Ta2O5 and ZrO2 in a specific proportion and in specific amounts.
