For pharmaceuticals, knowing the chemical composition is not enough - molecular geometry and crystal structure also play an important role in a drug's activity. By using a method based on electron ...

XRD works by directing X-rays onto a crystalline material and analyzing the angles and intensities of the diffracted beams. The atomic planes within the crystal act as a three-dimensional grating, ...

X-ray diffraction (XRD) is an essential technique to identify the structures and compositions of newly developed materials. However, XRD patterns consist of multiple peaks, and it is not always ...

Researchers at Lawrence Berkeley National Laboratory have developed a 4D-STEM workflow that can isolate and solve atomic structures from individual nanocrystals buried inside dense, tangled clusters, ...
