1.97007 femtometre (quadrillionths of a metre): That’s how unimaginably tiny the radius of the atomic nucleus of helium-3 is. This is the result of an experiment at PSI that has now been published in ...

Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

Scientists report the first look at electrons moving in real-time in liquid water; the findings open up a whole new field of experimental physics. In an experiment akin to stop-motion photography, ...

The study of biological systems varies from whole organisms, organs, and organoids, down to their building blocks of proteins and cells. At the lower end of the scale, atomic force microscope (AFM) ...

Dr. Liam Spillane shares breakthroughs in cryo-EM spectroscopy, emphasizing dose-fractionated EELS and direct detection technologies for superior data quality.

(Nanowerk News) In an experiment akin to stop-motion photography, scientists have isolated the energetic movement of an electron while “freezing” the motion of the much larger atom it orbits in a ...
