What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

Light scattering as the basis for size determination of many objects has been explored for a long time. It was Gustav Mie, author of the Mie Scattering Theory, who studied gold nanoparticles in ...

The image tweeted by Trump was at about 10-centimeter resolution. It was likely a picture taken by the US224 satellite. This was one of the upgraded keyhole satellites that have the same mirror as the ...

Diffraction gratings are curious things. Score a series of equally spaced tiny lines in a surface, and it will cause reflected or transmitted light to bend and separate into its component wavelengths.

With the development of different techniques for the synthesis of nanomaterials, researchers are constantly looking for a more precise instrument for their nanoscale characterization. X-ray ...

Lab scale: Members of Ashley Bucsek’s group can now use three-dimensional X-ray diffraction to study polycrystalline materials on campus, whereas they would previously only have been able to do this ...

Fluorescence microscopy techniques are powerful tools for probing very small signals and revealing three-dimensional (3D) structural and functional properties of biological samples with high ...
