Hall of Light

In front is the Hall of Light (mingtang), behind is the Crimson Palace (jianggong). 

After completion of the award ceremony in the Concert Hall we were driven to the city hall for the Nobel banquet. By this time it was a bitterly cold, windy evening. The courtyard of the city hall was lighted by the torches of hundreds of school children lining it. It was a most impressive sight, but we felt sorry for the children, who must have braved the weather for a long while. 

Marble walls and crystal lamps flank windows that let light into the Hall of Mirrors in the Chateau de /ersailles. (Corbis Corporation)...

Fig. 37. Band edge profile of a (In,Mn)As/GaSb heterostmcture. Eq. E. and Ep denote band edges of conduction band, valence band, and Fermi level, respectively, (b) Temperature dependence of the magnetization observed during cooldown in the dark (open circles) and warmup (solid circles) under a fixed magnetic field of 0.02 T. The effect of light irradiation at 5 K is also shown by an arrow, (c) Magnetization curves at 5 K observed before (open circles) and after (solid circles) light irradiation. Solid line shows a theoretical curve, (d) Hall resistivity />Hall observed at 5 K before (dashed line) and after (solid line) light irradiation (Koshihara...

The efficiency of light was calculated, using the same expression, for all the references from which we could get the necessary parameters. The expression used was the following (Hall et al., 1995 Markov et al., 1996) ...

Van Damme and Hall (262) studied the oxidation of H2 over LaCo03, MTi03 (M = Sr, Ba), and Ba(Feo.33Tio.67)C>2.67 either in the dark or while being irradiated with band-gap light. No effect of light on the rate of the oxidation was found with any of these materials. These authors described this reaction as a process dominated by charge transfer in the boundary layer of the catalysts. More recently, Futai et al. (266) studied the activity...
