In the polyspheron theory of nuclear structure,' approximate wave functions for the normal state and some excited states of nuclei are constructed of localized is orbitals occupied by one to four nucleons; a nucleus is described in terms of deuterons, tritons, trelions,2 and helions,3 as well as neutrons and protons not included in these clusters (spherons). In the following paragraphs I point ...

In this work, an attempt has been made to modify the shape and nanostructure of core-shell materials, which have been usually generated on the basis of amorphous spherical cores. Novel core-shell silicate particles, each of which consists of a silicalite-1 zeolite crystal core and mesoporous shell (ZCMS), were synthesized for the first time. The ZCMS core-shell particles are unique because they...

The evolution of the optical phonon spectra of colloidal core/shell CdSe/ZnS quantum dots with an increase of the shell thickness from 0.5 to 3.4 monolayers has been studied by resonant Raman spectroscopy. The results obtained suggest that the ZnS shell changes its structure from amorphous to partly crystalline as the thickness increases. Simultaneously, an increase in Raman scattering by surfa...

we report the fabrication of pure CeO2, ZnO and SiO2 deposited CeO2 hybrid core-shell nanoparticles by simple and cost effective co precipitation method. The as synthesized samples were characterized by various experimental techniques such as XRD (X-ray diffraction), FTIR (Fourier Transform Infrared Spectroscopy) and HRTEM (High Field Transmission Tunneling Microscopy) measurements. XRD results...
