Accelerated Lanthanide Intercalation into Graphite Catalyzed by Na
Akira Iyo, Hiroshi Fujihisa, Yoshito Gotoh +4
Lanthanides () are notoriously difficult to intercalate into graphite. We investigated the possibility of using Na to catalyze the formation of -intercalated graphite and s…
Na-catalyzed rapid synthesis and characterization of intercalated graphite CaC6
Akira Iyo, Hiroshi Fujihisa, Yoshito Gotoh +4
In this study, we conducted experiments on CaC6 for elucidating the Na-catalyzed formation mechanism and achieving rapid mass synthesis of graphite intercalation compounds (GICs).…
Uniaxial negative thermal expansion in an orthorhombic superconductor CoZr3
Hiroto Arima, Tatsuki Inui, Aichi Yamashita +5
We investigated the temperature evolution of crystal structure of orthorhombic CoZr3, which is a superconductor with a transition temperature of 4.3 K, by synchrotron and laborator…
Beryllium Polyhydride Be4H8(H2)2 Synthesized at HP/HT
Takahiro Matsuoka, Hiroshi Fujihisa, Takahiro Ishikawa +6
We report the XRD and Raman scattering measurements in combination with DFT calculations that reveal the formation of beryllium polyhydride Be4H8(H2)2 by laser heating Be/H2 mixtur…
Na-Au intermetallic compounds formed under high pressure at room temperature
K. Takemura, H. Fujihisa
High-pressure powder x-ray diffraction experiments have revealed that sodium and gold react at room temperature and form new Na-Au intermetallic compounds under high pressure. We h…
