Microcrystal electron diffraction, or MicroED, is a CryoEM method that was developed by the Gonen laboratory in late 2013 at the Janelia Research Campus of the Howard Hughes Medical Institute. MicroED is a form of electron crystallography where thin 3D crystals are used for structure determination by electron diffraction. The method was developed for structure determination of proteins from nanocrystals that are typically not suitable for X-ray diffraction because of their size. Crystals that are one billionth the size needed for X-ray crystallography can yield high quality data. The samples are frozen hydrated as for all other CryoEM modalities but instead of using the transmission electron microscope (TEM) in imaging mode one uses it in diffraction mode with an extremely low electron exposure (typically < 0.01 e−/Å2/s). The nano crystal is exposed to the diffracting beam and continuously rotated while diffraction is collected on a fast camera as a movie. MicroED data is then processed using traditional software for X-ray crystallography without the need for specialized software for structure analysis and refinement. Importantly, both the hardware and software used in a MicroED experiment are standard and broadly available. (Wikipedia).

Refraction (1 of 5) What is Refraction? An Explanation
Refraction, A conceptual qualitative explanation. Refraction is the change in direction of a ray of light as it passes from one medium to another. The amount of refraction is determined by the index of refraction of the media and the angle of incidence. For light, refraction follows Snell
