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...

Dynamic light scattering (DLS) using noninvasive backscatter (NIBS) detection technology is capable of measuring the hydrodynamic radius of proteins over a large concentration range (0.1 mg/mL to 100 mg/mL). As a result, it is possible to determine, in actual biopharmaceutical formulations, the bulk viscosity/restricted diffusion interaction parameter (kD), particle interaction parameter (B22),...

We study the equilibrium liquid structure and dynamics of dilute and concentrated bovine eye lens α-crystallin solutions, using small-angle X-ray scattering, static and dynamic light scattering, viscometry, molecular dynamics simulations, and mode-coupling theory. We find that a polydisperse Percus-Yevick hard-sphere liquid-structure model accurately reproduces both static light scattering data...

Many food systems consist of mixtures of protein and polysaccharide and many are also thermally processed. Potential interaction phenomena in solutions ofprotein and polysaccharide are described using the following probes: sedimentation velocity and sedimentation equilibrium analytical ultracentrifugation, dynamic light scattering and total intensity light scattering coupled to an on-line gel p...

new kinds of hydroquinone derivatives were synthesized and along with a azo dye applied as additives in the iodide/iodine redox electrolyte for dye-sensitized solar cells and their effect on the short-circuit photocurrent of dye sensitized solar cells was investigated. addition of 0.05 m a hydroquinone derivative in the electrolyte comprising 0.5 m 1-methyl-3-propylimidazolium iodide (mpii) and...

We have employed dynamic light scattering and X-ray small-angle scattering for monitoring the cluster formation of hen-egg white lysozyme solutions under crystallization conditions. From time-resolved dynamic light scattering experiments we can obtain a set of observables that exhibit clear extrema, when simultaneously plotted as functions of protein and electrolyte molarity. Close to these ext...

This work demonstrates a novel broadband optical switch, based on dynamic-scattering effect in liquid crystals (LCs). Dynamic-scattering-mode technology was developed for display applications over four decades ago, but was displaced in favor of the twisted-nematic LCs. However, with the recent development of more stable LCs, dynamic scattering provides advantages over other technologies for opt...
