Creating defect-free sheets of Graphene is said to be one of the main ‘hurdles’ in the search for wide scale commercialization of the material… but why is it so important to form large defect free sheets?
Graphene has received an astonishing amount of interest these past few years, so much so that now it is commonly referred to as the miracle material that’s predicted to revolutionize the 21st century.
Scientists make extensive use of X-ray fluorescence to map elements in materials. However, this technique does not have the needed spatial sensitivity unless the probe is finely focused.
Scientists have now found a way to turn X-ray fluorescence into an ultra-high position-sensitive probe to measure tiny internal structures called nanostructures in thin films (Nature Communications, « Reconstruction of Evolving Nanostructures in Ultrathin Films with X-ray Waveguide Fluorescence Holography »).
