Picture of the Week
As the Dark Energy Survey begins its second year of observations, UCL scientists are at the forefront of its science programme. This week's 'Picture of the Week' is galaxy NGC 1398, snapped during the survey's observations.
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.
- The research appears in a paper published in the journal Nature Communications, entitled "Pair Distribution Function-Computed Tomography"
