Multiple-scattering suppression in dynamic light scattering based on a digital camera detection scheme

Multiple-scattering suppression in dynamic light scattering based on a digital camera detection scheme.

We introduce a charge-coupled device (CCD) camera-based detection scheme in dynamic light scattering that provides information on the single-scattered autocorrelation function even for fairly turbid samples. It is based on the single focused laser beam geometry combined with the selective cross-correlation analysis of the scattered light intensity. Using a CCD camera as a multispeckle detector,...

Entrapment–D-(+)-Glucose Water Nanodroplet: Synthesis and Dynamic Light Scattering

In the present research, the D-(+)-Glucose–confined water nanodroplets with mean size in the range of 6-11 nm were synthesized at D-(+)-Glucose different concentrations by AOT reverse micelles (RMs) method as a function of mass fraction of droplet (MFD) at the constant water-to-surfactant molar ratio ( W=40). The dynamic light scattering of the nano-sized water droplets containing the D-(+)-Glu...

Experimental suppression of multiple scattering : E†ect on dynamic and static scattering data

Combination of dynamic and static light scattering experiments gives important information on structural and dynamic properties of polymer solutions and colloidal suspensions. However, the analysis of light scattering experiments in turbid media is highly complicated due to the presence of multiple scattering. Recently, a one-beam set-up has been proposed and it could be shown that the cross co...

Dynamic Light Scattering

A HeNe laser beam incident on a sample of micron-sized spheres suspended in water scatters into a random pattern of spots of varying size, shape, and intensity. The pattern results from the coherent superposition of the outgoing waves scattered from the spheres. Because the spheres are in constant Brownian motion, the pattern randomly changes in time. A photodetector is placed in the pattern an...
