Measurement of size of superparamagnetic particles using dynamic light scattering

To determine the size of commercial superparamagnetic particles dynamic light scattering was chosen. Measured values were compared with the data received from the particles manufacturers....

Dynamic light scattering from the oriented lamellar state of diblock copolymers: The undulation mode.

We have observed, by dynamic light scattering, the undulation mode of the block copolymer lamellae in the ordered phase. This mode is observable only in a geometry where the scattering vector is parallel to the lam...
