Loss of Tie2 receptor compromises embryonic stem cell-derived endothelial but not hematopoietic cell survival.
Isao Hamaguchi,Tohru Morisada,Masaki Azuma,Kyoko Murakami,Madoka Kuramitsu,Mizukami Takuro,Kazuyuki Ohbo,Kazunari Yamaguchi,Yuichi Oike,Daniel J. Dumont,Toshio Suda +10 more
TL;DR: Interestingly, Tie2-/- ES cells did not show measurable defects in development of the hematopoietic system, suggesting that Tie2 is not essential for hematopolietic cell development.
Journal ArticleDOI
Differences in local structure around Co and Fe of the BiCo 1 − x Fe x O 3 system determined by x-ray absorption fine structure
Naoki Ishimatsu,T. Watanabe,Kengo Oka,Kengo Oka,Masaki Azuma,Masaichiro Mizumaki,Kiyofumi Nitta,T. Ina,N. Kawamura +8 more
TL;DR: In this paper, an element-specific interpretation of the polarization rotation in the M phase around the morphotropic phase boundary is presented, and the components of thermal vibration and static disorder are evaluated separately from the temperature dependence of the Debye Waller factor from 0.28em to 300 K.
Journal ArticleDOI
Ultrafast Control of the Polarity of BiCoO 3 by Orbital Excitation as Investigated by Femtosecond Spectroscopy
Yoichi Okimoto,S. Naruse,Ryo Fukaya,Takuji Ishikawa,Shin-ya Koshihara,Kengo Oka,Masaki Azuma,Katsuhisa Tanaka,Hideki Hirori +8 more
TL;DR: In this article, a femtosecond terahertz (THz) pulse was used to enhance the second-harmonic generation (SHG) in a polar material.
Journal ArticleDOI
Single-layer oxychloride superconductor Ca2-xCuO2Cl2 with A-site cation deficiency
Isao Yamada,Alexei A. Belik,Masaki Azuma,Masaki Azuma,S. Harjo,Takashi Kamiyama,Yuichi Shimakawa,Mikio Takano +7 more
TL;DR: In this paper, an oxychloride superconductor with a single CuO 2 plane in the unit cell was prepared without cation substitution using high-pressure synthesis, and it was shown that the Ca deficiency was the origin of the hole carrier.
Journal ArticleDOI
Pronounced Negative Thermal Expansion in Lead-FreeBiCoO 3 ‑Based Ferroelectrics Triggered by the StabilizedPerovskite Structure
Zhao Pan,Xingxing Jiang,Takumi Nishikubo,Yuki Sakai,Hayato Ishizaki,Kengo Oka,Zheshuai Lin,Masaki Azuma +7 more
TL;DR: In this paper, negative thermal expansion (NTE) with a giant volume shrinkage of 4.4%, comparable to the strongest NTE (ΔV = −4.8%) in PbTiO3-based perovskites, was achieved in a lead-free BiCoO3 derivative.
