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...

Citrate-capped gold nanoparticles with different colours and diameters were prepared by the reduction of HAuCl4 using sodium citrate. With increasing the size of gold particles, the plasmon absorption peaks were shifted to longer wavelength and the intensity of resonance light scattering was enhanced. The resonance light scattering of gold nanoparticles in the range of 500–600nmwas quenched by ...

in this paper, aggregation behaviors of aqueous solutions of short chain hydrophilic ionic liquids (ils), 1 – allyl - 3 - methylimidazolium chloride ([amim]cl), 1 - ethyl - 3 - methylimidazolium chloride ([emim]cl), 1 - butyl - 3 - methylimidazolium chloride ([bmim]cl), 1 - butyl - 3 - methylimidazolium tetrafluoroborate ([bmim]bf4) were investigated using conductivity and laser light scatterin...

A simple corrected resonance light-scattering (CRLS) technique was established to correct for any distortion of the resonance light scattering (RLS) spectra resulting from molecular absorption. By using an absorption cell holder to change the propagation direction of the incident light beam of a common spectrofluorometer, the molecular absorption was directly measured through a spectrofluoromet...

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...
