Probing dynamics of dense suspensions: three-dimensional cross-correlation technique

Characterization of Enzymatically Induced Aggregation of Casein Micelles in Natural Concentration byin SituStatic Light Scattering and Ultra Low Shear Viscosimetry

“…There exist several dynamic light scattering methods to handle turbid systems such as the two-color cross correlation technique (39), the 3-D cross correlation technique (40,41) and diffusive wave spectroscopy (9). However, the advantages of static light scattering are the possibility to reduce the sample thickness to reduce or even avoid multiple scattering, the higher resolution of the method, and the short measuring time (19).…”

Static Light Scattering on Dense Colloidal Systems: New Instrumentation and Experimental Results

“…We must add that Eqs. [8] elements and by the grazing incidence of the light. These and [9] are first-order approximations but they work well effects are very small and can only be seen in the case of as long as the transmittance of the sample stays above 0.3.…”

“…An efficient physical suppression this transmittance of 0.3 constitutes a real limit, especially of multiple scattering is achieved with the two-color cross when cylindrical cuvettes are used. In order to investigate correlation technique (5,6) and the 3-D cross correlation semi-dilute or dense colloidal systems it is necessary to retechnique (7,8), while diffusive wave spectroscopy (DWS) duce the sample thickness in an appropriate way, which is (2, 9, 10) is based on multiple scattering but is actually not much easier to accomplish with flat cells than with cylindriwell suited for particle sizing. Another recent method which cal cuvettes.…”

A new instrument for time-resolved static and dynamic light-scattering experiments in turbid media

“…One possible realization of the cross-correlation method is the two-color technique [12,14,16], which, however, poses extreme technical difficulties that have limited its application for routine measurements. Another implementation of such a cross-correlation approach is the so-called 3D cross-correlation scheme [14,17,18] that has been developed during the last few years to an extent that it can now be routinely applied for the characterization of turbid suspensions. There even exist instruments which combine the 3D cross-correlation with the echo technique and thereby give access to investigation of highly turbid and nonergodic samples [19].…”
