Self-assembly
Noritaka Mizuno and Sayaka Uchida
Polyoxometalates are nanosized metal–oxygen macroanions and suitable building blocks of ionic crystals with nano-structures in combination with appropriate macrocations. In this review, (1) formation of ionic crystals by the complexationof the polyoxometalates with a macrocation and the hydrophilic guest sorption properties, (2) effects of charges of polyoxo-metalates on the structures and sorption properties of ionic crystals, and (3) construction of both hydrophilic and hydrophobicchannels in the crystal lattice of the polyoxometalate-based ionic crystals are highlighted.
694 Bio-inspired Programmable Self-assemblyon DNA Templates
Kentaro Tanaka and Mitsuhiko Shionoya
Besides the biological importance of DNA as storage of genetic information, DNA is a smart molecule to assemble func-tional units since it is possible to use sequences of nucleobases to encode molecularly assembled systems in a predeterminedfashion over a wide range in size. This review highlights recent advance in precise control of molecular assembly on DNAtemplates directed towards functionalized materials.

700 Novel Synthesis of Nanoporous Nickel Oxideand Nickel Nanoparticles/Amorphous Car-bon Composites Using Soluble Starch as theTemplate
A simple and green synthetic route based on the use of soluble starch as the template has beenutilized to prepare novel Ni(OH)2/starch precursors. Nanoporous nickel oxide (NiO) and nickelnanoparticles/amorphous carbon (Ni/C) composites have been successfully prepared by thermaldecomposition of the novel Ni(OH)2/starch precursors in air and in nitrogen, respectively.

734 Deactivation of Ru/Al2O3 Catalyst for Pref-erential CO Oxidation in the Presence ofLow-concentration NH3 by Nitrosyl Species
The behavior of a Ru/Al2O3 catalyst for the preferential CO oxidation in the presence of low-concentration NH3 (21−75 ppm) was investigated. In contrast to the results in the absence ofNH3, the catalyst was rapidly deactivated at higher [O2]/[CO] ratios in the presence of NH3 byadsorbed nitrosyl species.
