Self-organized swelling of a metal-polymer bilayer directed by a corrugated mold was reported. The corrugated pattern by the elastomeric mold was observed from the earlier stages of swelling. The temporal evolution of the self-organized pattern was analyzed theoretically, and the experimental data were well matched with the analysis. The maximum harmonic number for the corrugated wave number was also analyzed. With a relatively large line width, irregular self-organized patterns were observed.

We present the formation of SnO2-In2O3 hetero nanostructures. Kinetically, SnO2 nanowires form prior to the heterostructure. In2O3shell was regularly distributed on the SnO2 nanowire surface, and form sheath subsequently. We theoretically explained the morphological evolution of an anisotropic heterostructure such as core-sheath structure.

A theoretical analysis of the nanodiamond graphitization was presented. Thermodynamic analysis of the nanodiamond showed three kinds of phase-diagram; smaller nanodiamond, nanodiamond-graphite, and larger nanodiamond. In the theoretical analysis, the most probable and the maximum volume fractions of graphite in the nanodiamond were 0.76 and 0.84, respectively regardless of the annealing temperature and the initial radius of the nanodiamond. The highest graphitization probability decreased with increasing annealing temperature.

A theoretical analysis explaining non-catalytic growth of one-dimensional (1D) nanorods on a substrate is presented. The nuclei undergo cluster migration which continues until the mean free time of the adatoms is larger than surface diffusion time during several consecutive nuclei growth steps. The most probable mechanism is the migration of six adatoms into one fixed adatom. After the cluster migration, the nuclei grow in an isotropic manner, until the nucleus reaches the size limit. The 1D growth of nanorods on the nuclei begins when the reactant dose is smaller than a certain value. The growth rate of the height is greater than that of the radius. This difference in the growth rate causes the aspect ratio to increase with growth time. The presented analysis explains well the experimental results of the non-catalytic growth of nanorods.
