New X-ray vision can reveal internal structure of objects
4 October 2013
A team of scientists, including UCL Chemistry's Andrew Beale, has developed a new kind of X-ray vision that is able to peer inside an object and map the three-dimensional distribution of its nano-properties in real time.
The researchers, based at a range of institutions in the UK, US and mainland Europe, say the novel imaging technique could have a wide
range of applications across many disciplines, such as materials
science, geology, environmental science and medical research.
"This development represents the latest installment in an area I have been involved in since 2007 where we have been developing non-invasive chemical imaging methods using X-rays to look at industrial catalysts," Beale explains.
"The work in this publication uses, as a second demonstration of the power of the technique, an industrial catalyst, containing material
that is normally very difficult to chemically image since it is too small to
see just a few nanometres in size."
"The technique overcomes this problem, bridging a
gap between chemical properties at the nanoscale with their
distribution at the micronscale - such properties being key to understanding
the physical properties of materials."
The research, published in the journal Nature Communications, explains how the new imaging technique uses scattered X-rays to form a three-dimensional reconstruction of the image.
More information on the study is available in press releases from the University of Manchester and the Brookhaven National Laboratory.
