A two-layer shallow-water model is used to investigate the transition of wind-driven double-gyre circulation from laminar flow to turbulence as the Reynolds number (Re) is systematically increased. Two distinctly different phases of turbulent double-

Droplet-free deposition of Si nanoparticle films has been studied applying time-resolved imaging of Si nanoparticles formed by laser ablation of Si targets in Ar gas. We found that Si nanoparticles can be deposited not only on substrates facing to th

We examine highly super-Eddington accretion disk models onto a neutron star for SS 433, based on two-dimensional hydrodynamical calculations. The super-Eddington accretion flows form a kind of standing shock elongated along the rotational axis of the

We have shown a theoretical method to construct structures called “hyper-graphite” which can be regarded as a generalization of the graphite structure. Based on the method, we propose a possible 3-dimensional network, which may be realized as a

The existence of the edge states of single-layered H-terminated graphitic ribbons predicted by Nakada et al. [Phys. Rev. B 54, 17 954 (1996)] has been confirmed by first-principles calculations within the framework of the local-density approximation

Based on the classical force constant models, we study numerically and analytically out-of-plane phonon-dispersion relations for two types of nano-graphite ribbons confined by the armchair- and zigzag-shaped edges. We demonstrate for two ribbons how

We discuss the n electronic states of a graphite sheet which has topological defects or edges on a nanometer scale. The former is the case that pairs of pentagonal and heptagonal rings are introduced in the hexagonal network of a graphite sheet. In t

It is shown that the non-bonding orbitals of many graphite-derived carbon frameworks can be understood in terms of the four non-bonding orbitals of the graphite sheet. Several infinite series of fullerenes with non-bonding orbitals are identified, an
