“…Changes of molecular electric quadrupolar moment : Molecular electric quadrupole moment ( Θ ) is a measure of the π‐electron cloud in a chemical system 132. 133 The results in Table S6 show that the Θ values along the orthogonal directions are negligibly small for the highly symmetric C 60 molecule,134 and that for the H 2 O molecule substantially larger. H 2 O encapsulation somewhat populates the delocalized π orbitals of the CC bonds of the otherwise ambiguous C 60 aromatic cage due to polarization, leading to an increase in the value of quadrupole moment tensor components in the three directions.…”

Based on an experimental observation, it has been controversially suggested in a study (Kurotobi et al., Science 2011, 33, 613) that a single molecule of water can completely be localized within the subnano-space inside the fullerene C(60) cage and, that neither the H atoms nor the O lone-pairs are linked, either via hydrogen bonding or through dative bonding, with the interior C-framework of the C(60) cage. To resolve the controversy, electronic structure calculations were performed by using the density functional theory, together with the quantum theory of atoms in molecules, the natural population and bond orbital analyses, and the results were analyzed by using varieties of recommended diagnostics often used to interpret noncovalent interactions. The present results reveal that the mechanically entrapped H(2)O molecule is not electronically innocent of the presence of the cage; each H atom of H(2)O is weakly O-H···C(60) bonded, whereas the O lone-pairs are O···C(60) bonded regardless of the conformations investigated. Exploration of various featured properties suggests that H(2)O@C(60) may be regarded as a unique system composed of both inter- and intramolecular interactions.

Nanoscience and Nanotechnology suggest that many of the current problems involving water quality can be solved or greatly ameliorated using the nanoscale adsorbents, called nanoadsorbents. Innovations in the development of novel carbon nanomaterials like fullerenes, carbon nanotubes, and graphene are among the most exciting and promising materials for water treatment-purification. This chapter gives detailed description of the structure, morphology, and adsorption properties of carbon nanoadsorbents. The textural properties of fullerene, carbon nanotubes, and graphene family are highlighted. A brief description of the effects of the electronic properties in the adsorption capability was inferred as well as how the adsorption of molecules may affect photoelectronic properties of carbon nanotubes.

In this work, the specific features of formation of a composite material consisting of a mixture of low-melting ground glass and waste active sludge, which is used for sewage purification, have been considered. It has been established that, after low-temperature (600-700 °C) short-term (30-60 min) treatment, specimens consist of a porous glass shell and a core saturated by carbon form. With change in temperature treatment conditions, the thickness and porosity of the shell and the size of the carbonized core change, leading to different absorption and adsorption properties. Due to the presence of a carbon-containing core, specimens absorb efficiently methylene blue (MB) from aqueous solution.
