TL;DR: The formation of complexes between SDS and the various protein aggregates at pH 3.0 was shown to occur by two main mechanisms: at low concentration of SDS, the complex formation occurs essentially by ionic binding between the positive residues of the protein and the negative sulfate heads of the surfactant.

TL;DR: The first small-angle X-ray scattering study of Triton X-100 at different temperatures and ionic strengths in order to measure molecular weight, shape, and hydration of this nonionic surfactant is described in this paper.
Abstract: This work describes the first small-angle X-ray scattering study of Triton X-100 at different temperatures and ionic strengths in order to measure molecular weight, shape, and hydration of this nonionic surfactant. The X-ray scattering study is performed on the detergent at different electron density contrast by varying the electron density of the solvent by addition of glycerol or thallium nitrate. This study detects, on the basis of small-angle X-ray scattering experiments and by using a different contrast between the Triton X-100 micelles and the applied solvent, the hydrophobic core when using the assumption of a 2-step density level within the molecule. Furthermore, quasielastic light scattering measurements of aqueous solutions of Triton X-100 were performed which allow measurement of the diffusion coefficient. 30 references.

TL;DR: A high spectral resolution lidar technique to measure optical scattering properties of atmospheric aerosols is described, and Aerosol optical properties, such as the backscatter ratio, optical depth, extinctionCross section, scattering cross section, and theBackscatter phase function are derived.
Abstract: A high spectral resolution lidar technique to measure optical scattering properties of atmospheric aerosols is described. Light backscattered by the atmosphere from a narrowband optically pumped oscillator-amplifier dye laser is separated into its Doppler broadened molecular and elastically scattered aerosol components by a two-channel Fabry-Perot polyetalon interferometer. Aerosol optical properties, such as the backscatter ratio, optical depth, extinction cross section, scattering cross section, and the backscatter phase function, are derived from the two-channel measurements.

TL;DR: Continuous-wave ultrasonic modulation of scattered laser light has been used to image objects in tissue-simulating turbid media for what is to the authors' knowledge the first time and has the potential to provide a noninvasive, nonionizing, inexpensive diagnostic tool for diseases such as breast cancer.
Abstract: Continuous-wave ultrasonic modulation of scattered laser light has been used to image objects in tissue-simulating turbid media for what is to our knowledge the first time. The ultrasound wave focused into the turbid media modulates the laser light passing through the ultrasonic focal zone. The modulated laser light collected by a photomultiplier tube reflects the local mechanical and optical properties in the focal zone. Buried objects are located with millimeter resolution by scanning and detecting alterations of the modulated optical signal. This technique has the potential to provide a noninvasive, nonionizing, inexpensive diagnostic tool for diseases such as breast cancer.
