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...
متن کاملPredicted light scattering from particles observed in human age-related nuclear cataracts using mie scattering theory.
PURPOSE To employ Mie scattering theory to predict the light-scattering from micrometer-sized particles surrounded by lipid shells, called multilamellar bodies (MLBs), reported in human age-related nuclear cataracts. METHODS Mie scattering theory is applicable to randomly distributed spherical and globular particles separated by distances much greater than the wavelength of incident light. Wi...
متن کاملEmulsion glasses: A dynamic light-scattering study
A liquid-glass transition was observed experimentally in a new system, an oil-in-water emulsion. Dynamic light scattering was employed to obtain the intermediate scattering function f(q,t) for a range of volume fractions f and scattering vectors q. The results are compared with predictions of the mode coupling theory. While the usual idealized version of the theory provides accurate fits to the...
متن کاملSurfactant micelle characterization using dynamic light scattering
At low concentrations, surfactant molecules are unassociated monomers. As the concentration of surfactant is increased, the attractive and repulsive forces between the molecules cause self-aggregation to occur resulting in the formation of monolayers or micelles (Figure 1). The concentration at which these micelles form is called the critical micelle concentration (cmc). The characteristics of ...
متن کاملMie light scattering calculations for an Indian age-related nuclear cataract with a high density of multilamellar bodies
PURPOSE Multilamellar bodies (MLBs) are lipid-coated spheres (1-4 microm in diameter) found with greater frequency in the nuclear region of human age-related cataracts compared with human transparent lenses. Mie light scattering calculations have demonstrated that MLBs are potential sources of forward light scattering in human age-related nuclear cataracts due to their shape, size, frequency, a...
