Advance in X-ray imaging shines light on nanomaterials
Date:8/7/2012

A new advance in X-ray imaging has revealed the dramatic three-dimensional shape of gold nanocrystals, and is likely to shine a light on the structure of other nano-scale materials.

Described today in Nature Communications, the new technique improves the quality of nanomaterial images, made using X-ray diffraction, by accurately correcting distortions in the X-ray light.

Dr Jesse Clark, lead author of the study from the London Centre for Nanotechnology said: "With nanomaterials playing an increasingly important role in many applications, there is a real need to be able to obtain very high quality three dimensional images of these samples.

"Up until now we have been limited by the quality of our X-rays. Here we have demonstrated that with imperfect X-ray sources we can still obtain very high quality images of nanomaterials."

Up until now, most nanomaterial imaging has been done using electron microscopy. X-ray imaging is an attractive alternative as X-rays penetrate further into the material than electrons and can be used in ambient or controlled environments.

However, making lenses that focus X-rays is very difficult. As an alternative, scientists use the indirect method of coherent diffraction imaging (CDI), where the diffraction pattern of the sample is measured (without lenses) and inverted to an image by computer.

Nobel Prize winner Lawrence Bragg suggested this method in 1939 but had no way to determine the missing phases of the diffraction, which are today provided by computer algorithms.

CDI can be performed very well at the latest synchrotron X-ray sources such as the UK's Diamond Light Source which have much higher coherent flux than earlier machines. CDI is gaining momentum in the study of nanomaterials, but, until now, has suffered from poor image quality, with broken or non-uniform density. This had been attributed to imperfect coherence of the X-ray light used.
