Hard x-rays to watch chemical reactions

Researchers have developed an imaging technique which will allow scientists to study light elements such as carbon and oxygen using 'hard' x-rays. They say the new form of imaging could be used to study reactions in situ. 

In traditional x-ray imaging, x-rays are passed through a sample to create an image based on absorption of the material. Multiple images can then be reconstructed by computer to create a three-dimensional image. Often researchers combine this imaging with spectroscopy, to gain information about the chemical environment of an element.  More...
