A remarkable pink diamond, thought to have once belonged to Marie Antoinette, the last queen of France, has recently been ...

Iron is one of the most abundant heavy elements in the universe. Its spectral features stand out in many astronomical spectra, especially in those of stars and galaxies. As a dominant emitter in many ...

Yet the broader regions of absorption, which can be difficult to observe with the spectroscope, often have a greater influence on a diamond’s color. A chart has been prepared to illustrate the visible ...

A highly efficient absorption is observed in multipicosecond laser pulse irradiation of argon and nitrogen gas cluster targets at moderate intensities of /spl sim/10/sup 15/ W/cm/sup 2/ using a 1.5 ...

This is comparable to the Fraunhofer lines in the solar spectrum, which give an indication of the atoms in the Sun's atmosphere. In the terahertz spectrum of Venus, an absorption line appears that is ...

Novel faraday rotation spectroscopy sensor enables simultaneous two-component detection of nitrogen oxides Peer-Reviewed Publication Hefei Institutes of Physical Science, Chinese Academy of Sciences ...

InGaN thin films with near entire indium composition range have been successfully grown on GaN/sapphire (0001) by molecular beam epitaxy (MBE). Samples are studied by X-ray absorption fine structure ...

First, we compared the absorption spectra of proteinuria and non-proteinuria. Next, we investigated the effect of pH (6.0–9.0) on the analysis of proteinuria. Finally, we investigated the absorption ...

The ground state absorption spectrum of the nitrogen-doped diamond crystal is shown in Figure 1. It is well known that the intrinsic diamond exhibits the wide optical transparency range (from the ...
