The highest-resolution image of atoms so far has been captured, breaking a record set in 2018.
David Muller at Cornell University in Ithaca, New York, and his colleagues captured this image using a praseodymium orthoscandate crystal. They used a technique called ptychography, in which they shone x-rays on the crystal and then used the angles of scattered electrons to work out the shape of the atoms that scattered them.
This image is double the resolution of a zoomed-in image of atoms made in 2018 by Muller and his team, which was itself triple the resolution of others taken at the time with different techniques.
In 2018, Muller and his team used a 2D material to limit the amount of electron scattering that happens in a…
