 | Structure and properties of glasses with optical functions
|
| ZnO photochromic glass |
Change in color with the irradiation of light |
| Glasses containing heavy metal oxide, such as, TeO2
and Bi2O3 |
Light with the wavelength different from the incident
beam is emitted, or irradiation of light lets electricity pass through the glasses. |
| Non-oxide glasses, such as, halide or chalcogenide
glasses |
Selective transparency against specific wavelength |
| Non-linear optics of glass and ceramic
|
| SHG or THG (second / third harmonic generation) from
glasses or crystalline materials Surface-crystallized glass ? control of the surface
crystallization of optical crystals
Phase separation in glass and its effects on the optical properties |
Light with the intensity or wavelength different from
the incident beam comes out from the glass, or the glass itself emits light. And make
crystalline materials with such properties |
| Preparation of functional amorphous thin films
|
| Electrochromic WO3 films |
Reversible coloration and bleaching by an
electrochemical reaction |
| Amorphous films in the SiO2-TiO2
system |
Unique properties which are not achieved in the bulk
glasses |
| Improvement in characteristics of ceramics and development of inorganic catalysts
|
| Chemical durability of CaO-based ceramics |
Extend the lifetime in use |
| Catalytic property for the CaO-based ceramics |
How SOx can be absorbed efficiently? |
| Analyses of electronic structure of inorganic materials and computational chemistry
|
| Electronic states of glasses with X-ray photoelectron
spectroscopy |
Einstein’s photoelectric effect helps us to understand
various properties of glasses |
| Molecular orbital and molecular dynamic simulations |
Computer simulations are able to reproduce electron
distribution and atomic configuration. Interactions between electrons and atoms determine
chemical character of materials. |
| Development of combustion furnace reducing the emission of dioxins from urban wastes
|
Refractory brick with high durability
Re-utilization of furnace slag |
Low emission of dioxins and high efficiency in energy
recovery by burning wastes at higher temperature and by using the combustion heat for
generation of electricity. |
