Jason Bardi, American Institute of Physics Researchers at Harvard-Smithsonian Center for Astrophysics Finger Silicon-Capped Hydrocarbons as Possible Source of Mysterious "Diffuse Interstellar Bands" Over the vast, empty reaches of interstellar space, countless small molecules tumble quietly though the cold vacuum. Forged in the fusion furnaces of ancient stars and ejected into space when those stars exploded, these lonely molecules account for a significant amount of all the carbon,...

Los Alamos National Laboratory The project demonstrates that superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight. A house window that doubles as a solar panel could be on the horizon, thanks to recent quantum-dot work by Los Alamos National Laboratory researchers in collaboration with scientists from University of Milano-Bicocca (UNIMIB), Italy. Their project demonstrates that superior light-emitting properties...

Using 'dark channel' fluorescence, scientists can explain how biochemical substances carry out their function Spectroscopic techniques are among the most important methods by which scientists can look inside materials. They exploit the interaction of light waves with a given sample. Now, using X-ray absorption spectroscopy, researchers from Helmholtz-Zentrum Berlin fr Materialien und Energie (HZB) have observed the moving of electric charges from solute to solvent "“ so-called electron...

Astronomy & Astrophysics is publishing the first clear detection of signatures long sought in the spectra of X-ray astronomical sources, the so-called EXAFS signatures, standing for "Extended X-ray Absorption Fine Structure". EXAFS is a powerful tool for studying the structure of grains in the interstellar medium (ISM). It gives a more detailed picture of the composition and structure of amorphous grains in the ISM. Astronomy & Astrophysics is publishing the first clear detection of...

It might seem at first glance to be one of the simpler techniques performed at the Australian Synchrotron, but X-ray absorption spectroscopy requires a beamline that is very finely tuned. The technique measures the amount of X-rays absorbed by a sample while scanning a selected range of X-ray energies. The result is information on what elements are present and in what chemical form, what their local environment is and how they are bonded. The technique is only available at synchrotrons. The...
