Several recent experiments identify unusual patterns in particle diffusion, hinting at some underlying complexity in the process which physicists have yet to discover. Through new analysis published ...

Quantum dots diffuse within living cells in a nearly two-dimensional fashion. This result, which was obtained using a new 3D microscopy technique that can track single particles, sheds fresh light on ...

Glass transition is a Grand Challenge in condensed matter physics and still reveals surprises, despite decades of intense research. For instance, diffusion in glassy liquids was until now thought to ...

When light is scattered from a solution or a suspension, it undergoes random changes in intensity. This phenomenon helps us to determine the size of the particles that scatter the light. This is the ...

Dynamic light scattering techniques are used to determine particle size distributions of protein therapeutic formulations. In DLS-based measurement, scattering intensity changes are associated across ...
