We study the vibrational energy diffusion in single-walled carbon nanotubes by using the molecular-dynamics method. It is found that energy transports ballistically at low temperature and superdiffusively at room temperature. The velocity of energy transport along the axis in carbon nanotube at room temperature is abo…

We succeeded in developing carbon nanotube (CNT) vias specifically adapted for the copper interconnect process used in ultra large-scale integrated circuits. The CNTs were grown selectively on titanium films using Co catalyst films. The use of tantalum enabled CNTs to be grown on Cu lines and prevented any increase in…

A systematic crystal-chemical investigation of orthorhombic holmquistites has been done to determine the reasons for their - limited compositional variations. Structural constraints to the relative stability of B Li amphiboles are also suggested by the occurrence of ferro- and feni-ferroclinoholmquistites, and the la…

Low toxicity? Lanthanide carbides contained within carbon nanocapsules (see HRTEM image) might act as efficient contrast agents or tracers, however, their toxicity must first be assessed. With a chemical stability similar to TiO2 nanoparticles, such nanocapsules were added to macrophages from rat fibroblasts, with cyt…

A charge carrier confined in a quasi-one-dimensional helical nanostructure in the presence of an electric field normal to the axis of the helix is subjected to a periodic potential proportional to the strength of the field and the helix radius. As a result, the behavior of this carrier is similar to that in a semicond…
