The present work demonstrates a validation of small-angle X-ray scattering (SAXS) combining with ultra violet and visible (UV-vis) spectroscopy and quasi-elastic light scattering (QELS) analysis for characterization of silver sols synthesized in polymer matrices. Polymer matrix internal structure and polymer chemical nature actually controlled the sol size characteristics. It was shown that for...

The size of gold nanoparticle aggregates was controlled by manipulating the interparticle interaction. To manipulate the interparticle interaction of gold nanoparticles prepared by citrate reduction, we applied the substitutive adsorption of benzyl mercaptan on the particle surface in the absence of the cross-linking effect. Various experimental techniques such as UV-vis absorption spectroscopy...

Elastic scattering spectroscopy (ESS), in the form of wavelength-dependent backscattering measurements, can be used to monitor apoptosis in cell cultures. Early changes in backscattering upon apoptosis induction are characterized by an overall decrease in spectral slope and begin as early as 10 to 15 min post-treatment, progressing over the next 6 to 8 h. The timescale of early scattering chang...

The passage of seismic waves through highly heterogeneous media leads to significant scattering of seismic energy and an apparent attenuation of seismic signals emerging from the heterogeneous zone. The size of this scattering attenuation depends on the correlation properties of the medium, the rates of Pand S-wave velocities, and frequency content of the incident waves. An estimate of the effe...

We present recent results on elastic and inelastic low/medium energy electron interaction with tetrahydrofuran, C4H8O, tetrahydrofurfuryl alcohol, C5H10O2 and 3hydroxytetrahydrofuran, C4H8O2 molecules in gaseous phase. A comparative study of both absolute differential cross sections for elastic electron scattering and electron energy loss spectra, in a wide incident electron energy range from 5...

We compare a few types of high energy reactions which seem to be practical for polarimetry at RHIC. Coulomb-nuclear interference (CNI) in pp elastic scattering leads to a nearly energy-independent left-right asymmetry AN (t) at small t. The systematical uncertainty of this method is evaluated to be ∼ 10%. The CNI in proton-nucleus elastic scattering is predicted to result in larger values of AN...

Composition depth profiling of HfO(2) (2.5 nm)/SiON (1.6 nm)/Si(001) was performed by three diffetent analytical techniques: high-resolution Rutherford backscattering spectroscopy (HRBS), angle-resolved X-ray photoelectron spectroscopy (AR-XPS) and high-resolution elastic recoil detection (HR-ERD). By comparing these results we found the following: (1) HRBS generally provides accurate depth pro...

We have implemented Raman scattering in a vector radiative transfer model for coupled atmosphere and ocean systems. A sensitivity study shows that the Raman scattering contribution is greatest in clear waters and at longer wavelengths. The Raman scattering contribution may surpass the elastic scattering contribution by several orders of magnitude at depth. The degree of linear polarization in w...

The diffraction slope parameter is investigated for elastic proton-proton and proton-antiproton scattering based on the all available experimental data at low and intermediate momentum transfer values. Energy dependence of the elastic diffraction slopes is approximated by various analytic functions. The expanded ”standard” logarithmic approximations with minimum number of free parameters allow ...

Elastic and inelastic scattering of 'Li from "C have been measured at incident energies of 63 and 78.7 MeV. The experimental data were obtained over an angular range from 8„,=8' to 40'. Optical model parameters have been extracted by fitting the elastic scattering data, and deformation lengths have been obtained for the 'Li* (0.48 MeV) state and the "C~ (4.44 MeV) state. No single parameter set...
