サメガレイClidoderma asperrimum の筋肉脂質における全-cis-5,8,11,14,17,20,23-ヘキサコサヘプタエン酸（26:7n-3）の存在
No full textFatty acid analysis of roughscale sole Clidoderma asperrimum flesh lipids was carried out by gas chromatography. An unidentified peak appeared in the chromatogram in the elution region of ≥C24 fatty acids. After enrichment by solvent partitioning, reversed-phase thin-layer chromatography (TLC), and argentation TLC, the peak component was subjected to structural analyses. The partially hydrogenated products after reaction with hydrazine hydrate gave seven isomers of cis-hexacosenoic acid (26:1). Gas chromatography-mass spectrometry (GC–MS) analyses of their dimethyl disulfide adducts identified the monounsaturates as 5-, 8-, 11-, 14-, 17-, 20-, and 23-26:1. The peak component was assigned to all-cis-5,8,11,14,17,20,23-hexacosaheptaenoic acid (26:7n-3). GC–MS analyses of the 4,4-dimethyloxazoline derivative and methyl ester confirmed this structure. This fatty acid is a rare, very long-chain polyunsaturated fatty acid (VLCPUFA). The concentrations of the acid found in roughscale sole were 0.69 ± 0.34% (N = 5) of total fatty acids in flesh lipids. Roughscale sole appears to be characterized by the occurrence of 26:7n-3, which is lacking in popular sources of methylene-interrupted VLCPUFA, such as vertebrate retina, spermatozoa, and herring. 北海道産サメガレイの筋肉脂質の脂肪酸をGC で分析したところ，炭素数24 以上の領域に未知のピークが出現した。この成分を濃縮後，数種の誘導体に変換してGC-MSに供した結果，同成分は全-cis-5,8,11,14,17,20,23-ヘキサコサヘプタエン酸（26:7n-3）と同定された。総脂肪酸中の含有量は供試5 個体の平均で0.69±0.34％であった。サメガレイは，n-3 系およびn-6 系超長鎖ポリエン酸の給源として一般的な高等動物の網膜，精子，ニシン油などには見られない26:7n-3 を含む点で特徴的である

Phys. 101, 033120 (2007) and may be found at https://doi.org/10.1063/1.2434835.We have achieved single-mode laser action in a one-dimensional hybrid photonic crystal (HPC) containing cholesteric liquid crystal (CLC) as a defect and experimentally investigated the polarization characteristics of the laser light. The laser light emitted from the HPC containing the CLC was linearly polarized, which was different from that of the simple CLC, despite the CLC being contained in this structure. We have theoretically calculated the optical propagation to justify the experimental result. The calculated result was in good agreement with the experimental result and showed the difference in optical characteristics between the simple CLC and the HPC containing the CLC

Low-threshold and high efficiency lasing upon band-edge excitation in a cholesteric liquid crystal
No full textThis article may be downloaded for personal use only. Any other use requires prior permission of the author and AIP Publishing. This article appeared in Yuko Matsuhisa, Yuhua Huang, Ying Zhou, and Shin-Tson Wu, Ryotaro Ozaki, Yuuki Takao, Akihiko Fujii, and Masanori Ozaki, Appl. Phys. Lett. 90, 091114 (2007) and may be found at https://doi.org/10.1063/1.2710777.A low threshold and high efficiency laser based on dye-doped cholesteric liquid crystals (CLCs) is demonstrated using an input excitation with the same handedness of circular polarization as the helical structure of the sample at the shorter wavelength band edge of the reflection band. The responsible mechanism originates from the dramatic increase of the optical density of state (DOS) at the band edges. The calculated DOS of the CLC system confirms the authors’ experimental results
Occurrence and distribution of cis-7-icosenoic acid in the lipids of Japanese marine fish, shellfish, and crustaceans
No full textThis paper reports the concentration and composition of the isomers of cis-icosenoic acid (20:1) in the fatty acids of various species of Japanese marine animals. The main purpose of this study is to reveal the distribution of a positional isomer, cis-7-20:1 (c7-20:1), in marine animals. Because this isomer overlaps with the c9-20:1 isomer in gas chromatography (GC) on the commonly used polar capillary columns, less information is available on its occurrence and distribution. In this study, the monounsaturated fatty acids isolated by argentation thin-layer chromatography were analyzed by GC using a highly polar capillary column, SLB-IL111 (100-m long), with the highest polarity among the commercially available GC columns. A clear separation between the c7- and c9-20:1 isomers enabled the analysis of all the isomers of 20:1 present in marine animals. The results confirmed that the c7 isomer was a minor component of the 20:1 in the pelagic fish, which is rich in the c9 and/or c11 isomers as reported previously. In contrast, the c7 isomer was one of the major isomers in flatfish, shellfish, crabs, and brittle star. In these samples, the c13 isomer also occurred at higher concentrations rather than the c9 isomer. Because such a specific pattern of the 20:1 positional isomers was generally observed in both benthic fish and its dietary animals, the c7 isomer in the benthic fish probably originated from its diet. These marine animals are used as food in Japan, and therefore the c7-20:1 isomer is consumed by humans
Ultraviolet light responses in photovoltaic properties of TiO₂ / conducting polymer heterostructure devices

This article appeared in Tokiyoshi Umeda, Yuuki Hashimoto, Hiroyoshi Mizukami, Tomoki Shirakawa, Akihiko Fujii, and Katsumi Yoshino, Appl. Phys. Lett. 85, 3139 (2004) and may be found at https://doi.org/10.1063/1.1804234.Photovoltaic properties of heterostructure devices of titanium oxide (TiO2) and conducting polymer thin films have been studied. Normal photovoltaic properties were stably observed upon the visible light irradiation of the wavelength range corresponding to the absorption of a conducting polymer, and unique photovoltaic properties were also observed upon the ultraviolet (UV) light irradiation of the wavelength range corresponding to the absorption of TiO2. UV light irradiation caused marked increases in the short-circuit current at the visible-wavelength range and in the open-circuit voltage. These properties have been discussed by considering the enhancement of the built-in field which originates from the hole accumulation caused by the trap levels in the TiO2 layer or TiO2 ∕ conducting polymer interface.
