Abstract Fullerenes, with their extensive application potentials, have been receiving attention for their possible usage as drug delivery vehicles and devices for sensor technologies. In this work, the optimized molecular geometries, some diagnostic geometric parameters, electronic characteristics, natural bond orbital examinations and the interaction phenomena between C60, Si- or Al-doped C60 and phenylalanine amino acid molecule were investigated by the quantum mechanical calculations. It is observed that the impurity addition and using water as the solvent intensify the interaction between fullerene and amino acid system. These lead to various alterations in the electronic properties and NH stretching values of the clusters studied.

AbstractExperimental data showing a decrease in the work function of carbon nanotube (CNT) bundles and arrays hydrogenated in hydrogen-containing plasma are presented. This plasma treatment leads to hydrogen chemisorption on CNTs, which results in a work-function decrease from 4.8 to 3.3 eV. The experimental data confirm quantum-mechanical calculations for single-walled CNTs of variable chirality. Calculations indicate that a decrease in the CNT work function depends on both the properties of CNT and the degree of its passivation by hydrogen.
