An Activity in Japan for Realizing CO2-Free Hydrogen Global Supply Chains

Journal of Chemistry and Chemical Engineering 2014年第2期8卷 163-170页

作者： masaharu Sasakura Yuki Ishimoto Ko Sakata The Institute of Applied Energy 14-2 Nishi-Shimbashi 1-Chome Tokyo 105-0003 Japan

The current basic energy plan of Japan was authorized in the Cabinet in June 2010, in which ambitious energy and environmental targets and policies giving nuclear power a pivotal role toward 2030 were described. At present, the Japanese government has been forced to review the basic energy plan in the wake of the great east Japan earthquake occurred on March 11, 2011 followed by the severe accident at the nuclear power plants in Fukushima. Before the disaster, the IAE （institute of applied energy） had realized that it was not clear how CO2-free hydrogen would contribute to solving various energy and environmental issues, or that prospects were not clear for large demand of CQ-free hydrogen other than FCVs （fuel cell vehicles）. In this connection, the authors organized a voluntary ＂Concept Study Group （in short）＂ in March 2011 and held four meetings until the end of March 2012. Through the quantitative studies using IAE＇s simulation model （GRAPE）, the common recognition was built in the concept study group that hydrogen could contribute to energy security and increase in zero-emissions electric power ratio in Japan. It was also estimated that global CO2-free hydrogen supply chains could be realized by degrees after 2020. Based on these results, the authors made a proposal that hydrogen should be added in the primary energy constitution for new basic energy plan to the Japanese government because imported hydrogen could be considered as a pseudo-primary energy like LNG （liquefied natural gas）. Now, the succeeding ＂Action Plan Study Group （in short）＂ has been held focusing on hydrogen demand in various applications, future pictures of CO2-free hydrogen chains and road maps. Activity results of the ＂Concept Study Group＂ are shown here.

Ohmic Hetero-Junction of n-Type Silicon and Tungsten Trioxide for Visible-Light Sensitive Photocatalyst

引用

Journal of Materials Science and Chemical Engineering 2017年第8期5卷 33-43页

作者： masaharu Yoshimizu Yuki Hotori Hiroshi Irie Special Doctoral Program for Green Energy Conversion Science and Technology Interdisciplinary Graduate School of Medicine and Engineering University of Yamanashi Yamanashi Japan Special Doctoral Program on Clean Energy Interdisciplinary Graduate School of Medicine and Engineering University of Yamanashi Yamanashi Japan Clean Energy Research Center University of Yamanashi Yamanashi Japan

Visible light-sensitive photocatalyst was developed by combining n-type silicon (n-Si) and tungsten trioxide (WO3, n-Si/WO3), yielding an ohmic contact in between. In this system, the ohmic contact acted as an electron-and-hole mediator for the transfer of electrons and holes in the conduction band (CB) of WO3 and in the valence band (VB) of n-Si, respectively. Utilizing thus- constructed n-Si/WO3, the decomposition of 2-propanolto CO2 via acetone was achieved under visible light irradiation, by the contribution of holes in the VB of WO3 to decompose 2-propanol and the consumption of electrons in the CB of n-Si to reduce O2. The combination of p-type Si (p-Si) and WO3 (p-Si/ WO3), not the ohmic contact but the rectifying contact, was much less effective, compared to n-Si/WO3.

由于表面张力与惯性力作用,静止流场内较大尺寸气泡[500<气泡雷诺数(Re)<2000]形成不规则几何形状,造成二维图形处理方法等效球体或椭球获取三维体积的方式误差较大。此外,由于不规则界面的散射和反射,引起二维图像处理中边界模糊,难以辨识。本文以高速摄像机获得的静止流场内大尺寸气泡二维灰度图像作为卷积神经网络(CNN)的输入,以图像内气泡二维投影面积及实验获得三维体积训练网络,并用训练好的网络预测气泡体积。实验采用小气泡叠加法获得真实气泡体积,与网络预测结果进行对比。结果表明,该方法与传统图像处理方法相比,不需要对气泡形状进行假设,提高了对大尺寸气泡的适用性。

Identification of TM9SF2 as a Candidate of the Cell Surface Marker Common to Breast Carcinoma Cells

引用

Chinese Journal of Clinical Oncology 2009年第1期6卷 1-9页

作者： Samah Abou-Sharieha Yuh Sugii Tuoya Dongwei Yu Ling Chen Heizou Tokutaka masaharu Seno Department of Medical and BioengineeringScience Graduate School of Natural Science and Technology Okayama UniversityOkayama 700-8530 Japan. SOM Japan Inc. Tottori 680-0941 Japan.

OBJECTIVE We aimed identification of cell surface molecules, which might serve as diagnostic biomarkers or useful targets for therapies, in breast cancer. METHODS We developed unique DNA microarray coupled with spherical self-organizing map （sSOM） analysis to characterize cells and tissues by the cell surface markers. In the microarray 1,797 probes for human genes coding membrane bound proteins were spotted. With this microarray the gene expression profiles of eight breast carcinoma cell lines were compared to identify the genes that were commonly expressed in breast carcinomas but not in normal cells. RESULTS The gene expression profiles of sSOM from the eight breast carcinoma cell lines were successfully distinguished from that of normal breast tissue derived cells suggesting the presence of genes of interest, sSOMon the data extensively filtered revealed several candidate genes, of which expression was significant in carcinoma cells but low in normal cells. Finally, TM9SF2 was nominated through validations of PCR procedures together with CD24 and ErbB3, which are known breast carcinoma markers. TMgSF2 expression was further confirmed by immunological staining. Interestingly, TMgSF2 was found to be expressed in all the cell lines evaluated while CD24 and ErbB3 were not in all of the carcinoma cells, supporting their relationship in sSOM. Although physiological significance of TMgSF2 is unknown yet, siRNA treatment significantly inhibited the growth of MDA- MB-231 cells. CONCLUSION We propose TM9SF2 as a novel and useful diagnostic marker as well as a potential molecular target specific to breast carcinoma cells covering wide range of breast cancer.

Rain Attenuation at Terahertz

引用

Wireless Engineering and Technology 2010年第2期1卷 92-95页

作者： S. ishii 不详

Rain attenuation values were calculated using empirical raindrop-size distributions, which were, Marshall-Palmer (M-P), Best, Polyakova-Shifrin (P-S) and Weibull raindrop-size distributions, and also calculated using a specific rain attenuation model for prediction methods recommended by ITU-R. Measurements of Terahertz wave taken at 313 GHz (0.96 mm) were compared with our calculations. Results showed that the propagation experiment was in very good agreement with a calculation from the specific attenuation model for use in prediction methods by ITU-R.
