Researchers have developed a new x-ray microscope that will provide scientists with the opportunity to image nanostructures and chemical reactions down to the nanometer.
The new class of x-ray microscope allows for nanoscale imagining like never before. This development brings researchers one step closer to the ultimate goal of nanometer resolution.
This from Brookhaven National Laboratory:
The microscope manipulates novel nanofocusing optics called multilayer Laue lenses (MLL) — incredibly precise lenses grown one atomic layer at a time — which produce a tiny x-ray beam that is currently about 10 nanometers in size. Focusing an x-ray beam to that level means being able to see the structures on that length scale, whether they are proteins in a biological sample, or the inner workings of a fuel cell catalyst.
Additionally, when a sample is scanned, researchers can collect various x-ray signals emerging from the sample. This is helpful in understanding crucial information about the materials, such as density, elemental composition, chemical state, and the crystalline structure of the sample.
“This instrument incorporates most recent developments in interferometric sensing, nanoscale motion, and position control. Recorded drifts of two nanometers per hour are unprecedented and set a new benchmark for x-ray microscopy systems,” said Evgeny Nazaretski, a physicist at National Synchrotron Light Source II who spearheaded the development of the microscope.
