Have You Ever Seen An Atom? This Is How It Looks Like

Atoms are really, really small. Atoms are about a thousand times smaller than the wavelengths of light that we see with. The distances between atoms are similarly small as well, and it is impossible to resolve atoms even using optical microscopes.

But there are advanced microscopy techniques which allow us to resolve individual atoms in a lattice. Scanning tunneling microscope is one such instrument. It does not use light to do the imaging, and works based on quantum tunnelling.read the full document.

Scientists at the University of California Los Angeles have found a way to create stunningly detailed 3D reconstructing of platinum nanoparticles at an atomic scale. These are being used to study tiny structural irregularities called dislocations.


Dislocations and their interactions strongly influence many material properties, ranging from the strength of metals and alloys to the efficiency of light-emitting diodes and laser diodes.
