When a laser experiment fails to produce the expected flash of light, most researchers would assume something went wrong with ...

A cloud of ultracold atoms is like a motel with a neon “no vacancy” sign. If a guest at the motel wants to switch rooms, they’re out of luck. No vacant rooms means there’s no choice but to stay put.

Liquids and solutions may look simple, but on the molecular scale they are constantly shifting and reorganizing. When sugar dissolves in water, each sugar molecule quickly becomes surrounded by fast ...

Usually, light waves can pass through each other without any resistance. According to the laws of electrodynamics, two light beams can exist in the same place without influencing each other; they ...

SLS includes multi-angle light scattering and right-angle light scattering, techniques that calculate the precise values of the molecular weight, weight-average molecular weight, and the radius of ...

Heterogeneous liquid samples are frequently subjected to dynamic light scattering as the method depends on the Brownian Motion effect to identify dispersed particles by their hydrodynamic radii. This ...

Dynamic Light Scattering is commonly used to rapidly measure the hydrodynamic size and size dispersity of nanoparticles in suspension. Several commercial DLS instruments exist, using a range of ...
