[Full Text PDF(J-STAGE)]
[Supporting Information]
Free Access Article
13C NMR and X-ray crystallographic analysis revealed that C70 takes both “end-on” and “side-on” orientations in the cavity of a cyclic nickel porphyrin dimer, whereas C70 adopts only a “side-on” orientation within the corresponding free-base dimer.

Imaging of Phosphatidylcholine Bilayers by a High-Pressure Fluorescence Technique: Detection of the Packing Difference
Hitoshi Matsuki,* Masaki Goto, Masataka Kusube, and Nobutake Tamai
[Full Text PDF(J-STAGE)]
A polarity-sensitive probe Prodan, which resides in the head-group region of a lipid molecule, shows the characteristic fluorescence spectra depending on the bilayer phase state. By using the nature of Prodan, packing imaging of phosphatidylcholine bilayers was done.

Mechanistic Study of the Palladium-Catalyzed Stereoselective Cross-Coupling Reaction of 1,1-Dibromo-3,3,3-trifluoro-2-tosyloxypropene
Masaki Shimizu,* Youhei Takeda, and Tamejiro Hiyama
[Full Text PDF(J-STAGE)]
[Supporting Information]
We prepared a Pd complex by the oxidative addition of 1,1-dibromo-3,3,3-trifluoro-2-tosyloxypropene to [Pd(PPh3)4]. The atomic distance between Pd and F in the complex was 2.95 Å, which was shorter than the sum of the van der Waals radii. Based on NMR studies of the oxidative addition step, a catalytic cycle for the Pd-catalyzed cross-coupling reaction of the propene is proposed, with the Pd–F interaction as the key element for the Z-selectivity.

Temperature Dependence of Ion Mobility of Carbon Cluster Cations: Intermediate Region Connecting Low- and High-Field Conditions
Kiichirou Koyasu, Tomohiro Ohtaki, and Fuminori Misaizu*
[Full Text PDF(J-STAGE)]
Temperature dependences of ion mobility of small carbon cluster cations were investigated with a drift cell coupled with a reflectron time-of-flight mass spectrometer. Under the present condition, it was found that hard-sphere model is more applicable.

Differences of Structures and Electronic Properties in the Triplet States between Dibromo and Dichloro Mononuclear Polypyridine Iridium(III) Complexes
Naokazu Yoshikawa,* Shinichi Yamabe, Nobuko Kanehisa, Tsuyoshi Inoue, Hiroshi Takashima, and Keiichi Tsukahara
[Full Text PDF(J-STAGE)]
[Supporting Information]
 | Triplet states were determined computationally to investigate the source of emission spectra. Two triplet state structures of [IrX2(bpy)2]+ and [IrX2(phen)2]+ and the interconversion transition states were obtained with X = Cl and Br. |

Growth of Cadmium Hexacyanidoferrate(III) Nanocubes and Its Application in Voltammetric Determination of Morphine
Shah Raj Ali,* Prakash Chandra, Mamta Latwal, Shalabh Kumar Jain, and Vipin Kumar Bansal
[Full Text PDF(J-STAGE)]
 | Cadmium hexacyanidoferrate(III) nanocubes with a size range of 60–90 nm have been synthesized and characterized using different analytical techniques. A cadmium hexacyanidoferrate(III) nanocube–carbon nanotube composite modified glassy carbon electrode was employed for voltammetric determination of morphine. |

The Impacts of Hg(II) Tightly Binding on the Alzheimer’s Tau Construct R3: Misfolding and Aggregation
Dan-Jing Yang, Shuo Shi, Tian-Ming Yao,* and Liang-Nian Ji
[Full Text PDF(J-STAGE)]
We originally set out to investigate the interaction of Hg2+ with Alzheimer’s tau construct R3, and its impacts on tau aggregation. The results could help us to understand the detailed mechanism of misfolding development and self-aggregation of tau protein from a toxicological perspective of metal ion to AD.

Masaaki Haneda,* Yasuyuki Doi, and Masakuni Ozawa
[Full Text PDF(J-STAGE)]
Ba-Doped Y2O3 catalysts show extremely high performance for NO decomposition. The presence of highly dispersed Ba species on the catalyst surface is essential for NO decomposition to proceed. Highly dispersed Ba species plays a role for the formation and adsorption of nitrite (NO2−) as reactive species.
