Many detailed reviews of laser scattering from fluids (1-16) have appeared since the comprehensive review by Chu (1) in this series. Among these, we would like to call attention to those by Swinney (14) on critical phenomena, by Gelbart (13) on collision-induced phenomena, by Pecora (7) on macromolecules in solution, and by Fleury & Boon (12) on the overall field of scattering from fluids. Over...

Iron oxide (Fe3O4) nanoparticles with average sizes of 10 nm were synthesized by a chemical coprecipitation method in the presence of chitosan. Chitosan as a natural polymer which can be extracted from crustaceans was used in the synthesis process in order to achieve more dispersed nanoparticles. Also, chitosan was used to obtain functionalized magnetic nanoparticles for using in different area...

In this study, aggregation behavior of a water soluble cationic metalloporphyrin, meso-tetrakis (2,3,5,6-tetrafluoro-N,N´,N´´-trimethyl ammonium phenyl) porphyrin nickel(II) [Ni(II)(TF4TMAPP)]4+ is investigated in 5 mM aqueous phosphate buffer of pH 7.0 at 25.0 °C and various ionic strengths using optical absorption and resonance light scattering spectroscopic methods. The...

A novel quaternary ammonium-based cationic gemini surfactant (S6) having 1,6 di-bromo hexane as a spacer, have been used and its interaction with insulin in aqueous solution (pH, 7.40) was investigated by several methods including fluorescence spectroscopy, UV-Vis spectroscopy, circular dichroism, dynamic light scattering, ζ-potential measurements, conductivity and transmission electron microsc...

The absolute coagulation rate constants of monodisperse spherical colloids in aqueous suspension were measured at the early stage of the coagulation processes by using two different techniques: single particle light scattering (SPLS) and simultaneous static and dynamic light scattering (SLS + DLS). Single particle light scattering determines the cluster-size distribution directly by counting th...

[1] The light scattering and light absorption as a function of wavelength and relative humidity due to aerosols measured at the Kaashidhoo Climate Observatory in the Republic of the Maldives during the INDOEX field campaign has been calculated. Using sizesegregated measurements of aerosol chemical composition, calculated light scattering and absorption has been evaluated against measurements of...
