Multilayered nanoheterostructures: theory and experiment
Article Abstract:
Multilayered spherical CdS/HgS nanocrystals consisting of two embedded HgS layers in CdS and multilayered ZnS/CdS nanocrystals with one embedded CdS layer in ZnS are prepared and are characterized by optical spectroscopy, XRD (X-ray diffractometry) and TEM (transmission electron microscopy). The results of the optical spectroscopy are compared to theoretical calculation and TEM results are compared to TEM simulations.

Ultramicroelectrode voltammetric investigation of intermicellar interaction and micellar growth of sodium dodecyl sulfate in aqueous NaCl solutions
Article Abstract:
Ultramicroelectrode voltammetric measurements are used to investigate the micellar self-diffusion coefficient (D(sub s)) and intermicellar interaction parameter (K(sub d)) of sodium dodecyl sulfate (SDS) in aqueous NaCl solutions. It is seen that the Coulombic nature of the interaction between micellar particles that control the micellar self-diffusion behavior in aqueous NaCl solutions.

Microstructural study of silica gel by positron annihilation
Article Abstract:
Microstructural studies of silica gel powder were carried out using positron annihilation lifetime spectroscopy (PALS) in conjunction with transmission electron microscopy (TEM). It was emphasized that two different positron annihilation mechanisms prevail in the microcavities and mesopores.
