the aggregation behavior of anionic cobalt(ii) 4,4′,4ʺ,4‴-tetrasulfonated phthalocyanine, [co(tspc)4-] was studied at its various concentrations and different ionic strengths using optical absorption and resonance light scattering (rls) spectroscopies in 5 mm phosphate buffer, ph 7.0 at 25 °c. the results show no aggregation behavior at concentration range of 5.1 × 10-6-7.5 × 10-5 m. also, the ...

according to circumstance of kerman sarcheshmeh cooper complex that its anode slime is mainly consisted of cu, ag, au, pb and se. in this work, recovery of silver from anode slime and subsequent synthesis of silver nanoparticles from leaching solution was made. silver was separated from anode slime by using of hno3 and hcl. x-ray fluorescence spectroscopy (xrf) was used to characterize anode sl...

As has been confirmed meanwhile by lattice-QCD calculations (see e.g. Ref. [1]), the confinement spectrum of non-exotic quark-antiquark systems has its ground state for scalar mesons well above 1 GeV in the Resonance Spectrum Expansion (RSE). For instance, in the S-wave Kπ RSE amplitude, a broad resonance was predicted slightly above 1.4 GeV [2], which is confirmed by experiment as the K 0 (143...

Background: Developing effective methods for the synthesis of bio-compatible and non-toxic nanoparticles is the main goal of nanotechnology. In the most chemical methods, a chemical reducing agent is used to reduce metal ions. But, in chemical methods, the stability of nanoparticles is controversial and synthesis in large sizes is much more difficult. Moreover, there is an incr...

The Earth’s atmosphere is an environment replete with particles of differ-ent sizes with various refractive indices which affect the light radiation traveling through it. The Mie scattering theory is one of the well-known light scattering techniques ap-plicable to modeling of electromagnetic scattering from tiny atmospheric particles or aerosols floating in the air or within the clouds. In this...

Gold nanocrystals exhibit unique optical properties in enhanced light absorption and scattering owing to their extremely large scattering/absorption crosssections and large electric field enhancements generated by localized surface plasmon resonance. In this work, the optical properties of gold nanospheres with diameters of 60 nm and 200 nm with remarkable uniformity in size were studied both ...

Rayleigh scattering spectra and Raman spectra from single bundles of aligned single-wall carbon nanotubes (SWNTs) have been obtained with dark field optical microscopy and Raman microscopy. Rayleigh scattering spectrum reveals resonance peaks due to the optically allowed interband transitions in SWNTs. The intensity of the resonance peaks was found to depend strongly on the incident light polar...
