A solid solution of a 100Li3PS4·xLi3PO4 electrolyte was easily prepared by liquid-phase synthesis. Instead the conventional solid-state synthesis methods, ethyl propionate used as reaction medium. The initial stage among Li2S, P2S5 and Li3PO4 proved ultraviolet-visible spectroscopy. powder X-ray diffraction (XRD) results showed that formed up to x = 6. At 20, XRD peaks were detected in sample a...

Building a quantum network is the ultimate goal of information science. Among candidates to realize node, repeater, and channel, solid-state emitters are particularly outstanding because presence spin-photon interface. Some such as carbon nanotubes, color centers, transition metal ions, rare earth ions can give telecom wavelength emission at room temperature. These have different origins single...

The thermal diffusivity of a series of solid solutions of alumina and chromia transformation toughened with a dispersed phase of unstabilized zirconia was measured by means of the laser-flash method from room temperature to 1400 ~ C. It was found, in general, that the thermal diffusivity could be decreased significantly by the combined effects of solid solution alloying, microcracking and by th...

We demonstrate tunable superluminal propagation in a silicon microphotonic device in a solid-state room-temperature device of tens of micrometers in dimension allowing easy integration with high-bandwidth room-temperature systems. We achieve tunable negative delays up to 85 ps and effective group indices tunable between -1158 and -312.
