A technique is demonstrated in which dense arrays of single-walled carbon nanotubes are synthesized combining traditional techniques of catalytic base growth with that of tip growth, to result in what is termed ¡°odako¡± growth. These structures, illustrated here, resemble giant kites named odakos that are typically fl own at traditional Japanese festivals.

Submicrometer sized pure cubic phase ¦Á-NaYF4, and its Eu3+ doped, and Yb3+/Er3+ co-doped particles with octahedral morphology have been prepared in acetic acid. The presence of acetate ions plays a critical role in the formation of such symmetric octahedral structures through its selective adsorption on the (111) faces of the products.

A variety of Si polymorphs have been synthesized and experimentally characterized. Definitive evidence was provided for the existence of stable hexagonal symmetry phases. The main reason for this was attributed to the fast growth kinetics which outplays cohesive energy in defi ning the crystal structure of chemically synthesized Si nanowires.
