Effect of the hydrostatic pressure and shell’s Al composition in the intraband absorption coefficient for core/shell spherical GaAs/AlGaAs quantum dots
(Elsevier, 2020-01)
In this paper we theoretically investigate the role of hydrostatic pressure by analyzing its influence on potential barrier’s height in GaAs/AlGaAs core/shell spherical quantum dots. The values of hydrostatic pressure ...
Electronic structure and molecular properties of the heptacyanorhenate [Re(CN)(7)](3-) and [Re(CN)(7)](4-) complexes
(AMER CHEMICAL SOC, 2006-06-26)
We report scalar relativistic and Dirac scattered wave (DSW) calculations on the heptacyanorhenate [Re(CN)(7)](3-) and Re(CN)(7)(4-) complexes. Both the ground and lowest excited states of each complex split by spin-orbit ...
Silver L1, L2 and L3 cross-sections for ionization and x-ray production by electron impact
(IOP Publishing, 2014-10)
The experimental determination of ionization cross-sections and total x-ray production cross-sections under electron impact is carried out for the three silver L-subshells. The very complexspectral structure involving ...
Versatile preparation of silica nanocapsules for biomedical applications
(Wiley VCH Verlag, 2020-04-14)
Core–shell nanocapsules are receiving increasing interest for drug delivery applications. Silica nanocapsules have been the focus of intensive studies due to their biocompatibility, versatile silica chemistry, and tunable ...
Structural and optical analysis of GaAsP/GaP core-shell nanowires
(AMER INST PHYSICS, 2009)
The structural and optical properties of GaAsP/GaP core-shell nanowires grown by gas source molecular beam epitaxy were investigated by transmission electron microscopy, Raman spectroscopy, photoluminescence (PL), and ...
Characterization of tetraethylene glycol passivated iron nanoparticles
(Elsevier B.V., 2014-10-01)
The present study describes the synthesis and characterization of iron@iron oxide nanoparticles produced by passivation of metallic iron in tetraethylene glycol media. Structural and chemical characterizations were performed ...

Core/Shell Structure of TiO2-Coated MWCNTs for Thermal Protection for High-Temperature Processing of Metal Matrix Composites
(Hindawi Ltd, 2018)
The production of metal matrix composites with elevated mechanical properties depends largely on the reinforcing phase properties. Due to the poor oxidation resistance of multiwalled carbon nanotubes (MWCNTs) as well as ...
Photoluminescence of core-shell nanoparticles made from yttrium stabilized zirconia powder grain coated with alumina
(Royal Society of Chemistry - RSCCambridge, 2013-05)
A YSZ@Al2O3 nanocomposite was obtained by Al2O3 coating on the surface of yttrium stabilized zirconia via a polymeric precursor method. The resulting core–shell structures were characterized by X-ray diffraction, scanning ...
