Excellent Support Center for Reaction, Nanomaterial and Biological Science by Electron Microscopy
(Nagoya University)

In this project conducted by High Voltage Electron Microscope Laboratory of Nagoya University, a reaction science high voltage scanning transmission electron microscope and many high performance electron microscopes (cluster) are provided for researches of material- and biological-science. The project enables microscopic elemental analysis, 3D observation, gas environment observation and extremely high resolution TEM/STEM and EELS observations and makes it possible to expand use through diversification of supporting items. The Nagoya University electron microscope group provides comprehensive support for the implementation of this project.

About this institute

The center provides a normal fee-charging program and a funding program. The later is a free trial use for only one sample at the first time. ( Foreign organization is not available.) User can select comprehensive support as desired from technical consultation, experimental design, sample fabrication, analysis, consulting and so on. Request for collaborative research will be also accepted. In principle, instruments in the laboratory will be operated by our technical staffs with you.

Main instruments: RE-HVSTEM allows in situ observations and EELS in gas atmospheres (N2, O2, H2, CO+air, etc.), in the pressure range of 1x10-6 - 1.3x104 Pa. A specimen holder inclinable up to ±70° in a vacuum and a fully rotatable holder are effective for 3D observations of thicker biological and non-biological specimens. A liquid Helium holder, a double-tilt heating holder, a high-temperature heating holder and a nano-indentation holder are also available. Moreover, high resolution observation less than 0.1 nm with ACSTEM, observation of nano electromagnetic field by electron holography with Cold-FETEM, and chemical analysis in the temperature range of 100 - 1000K using WDX, EELS and CL installed on Spectroscopic STEM can be conducted.
