466	Collective Interactions of Molecules with an Interfacial Solid
	Katsumi Kaneko, Tsutomu Itoh, and Toshihiko Fujimori
	[Full Text PDF(J-STAGE)] Open Access Article

	Molecules in nanoscale pores of the interfacial solid such as single wall carbon nanotube of which all component carbon atoms are exposed to the interfaces with gas phase show collective behavior, depending on the nanostructure. Confinement of molecules in nanoscale pores leads to stabilization of low-temperature phase and superhigh-pressure effect. Water molecules are adapted to hydrophobic nanopore spaces through cluster formation. The quantum fluctuation of H₂ and D₂ gives rise to a marked quantum molecular sieving effect. The Cu-based porous coordination polymer crystals can aspire CO₂ repeatedly without the collapse of the crystal lattice.

202	Self-assembled Nanogel Engineering for Advanced Biomedical Technology
	Yoshihiro Sasaki and Kazunari Akiyoshi
	[Full Text PDF(J-STAGE)]

	Nanogels are polymer nanoparticles with three-dimensional networks. Recently, various nanogels have been designed, with a particular focus on biomedical applications. In this review, we describe recent progress in the synthesis of functional nanogels by self-assembly of associating polymers and concept of nanogel engineering for advanced biomedical technology including regenerative medicine and drug delivery system.

9	A Revisit to Molecular Orbitals in H₂⁺, LiH, HF, and Hybridization
	Shin-ichi Nagaoka, Hiroyuki Teramae, and Umpei Nagashima
	[Full Text PDF(J-STAGE)]

	We have drawn three-dimensional contour plots of H₂⁺ molecular orbitals and carbon hybrid orbitals according to explanations given in quantum chemistry textbooks and have also performed ab initio molecular orbital calculations of LiH and HF. Some contour representations and molecular orbital energy level diagrams thus obtained are not consistent with the figures adopted in the textbooks. It is considered that the usual explanations for the molecular orbitals of H₂⁺, LiH, HF, and hybridization in the conventional textbooks are liable to misunderstanding.

2	Thioamides and Thioformamides for Sequential Reactions with Organolithium and Grignard Reagents
	Toshiaki Murai and Yuichiro Mutoh
	[Full Text PDF(J-STAGE)]

	Sequential reactions of thioamides and thioformamides with organolithium and Grignard reagents are described. Thioiminium salts derived from these sulfur isologues of amides readily react with lithium acetylides to lead to several types of products, including α,β-unsaturated ketones, whereas sequential additions of lithium acetylides and Grignard reagents afford propargylamines. The direct addition of organolithium and Grignard reagents to thioformamides proceeds with high efficiency to give a range of tertiary amines.
