Photon spheres in Einstein and Einstein-Gauss-Bonnet theories and circular null geodesics in axially-symmetric spacetimes
(American Physical Society, 2015-09)
In this article we extend a recent theorem proven by Hod [Upper bound on the radii of black-hole photon spheres, Phys. Lett. B 727, 345 (2013)] to n-dimensional Einstein and Einstein-Gauss-Bonnet theories, which gives an ...
Effects of self-assembly process of latex spheres on the final topology of macroporous silica
(Elsevier B.V., 2005-11-15)
This paper surveys the topology of macroporous silica prepared using latex templates covering the submicrometric range (0.1-0.7 mu m). The behavior of latex spheres in aqueous dispersion has been analyzed by dynamic light ...

Photocatalytic degradation of phenol using doped titania supported on photonic SiO2 spheres
(Springer, 2016-11)
The photocatalytic degradation of phenol in aqueous suspensions of co-doped TiO2 supported on SiO2 spheres was investigated. A novel photocatalyst was prepared combining iron doped TiO2?SiO2 and reduced TiO2?SiO2 by ...
Berry Phase in a Bloch-Like Sphere for Nonlinear Compton Scattering
(Institute of Electrical and Electronics EngineersPE, 2019-12)
We use a Bloch-like representation for nonlinear Compton scattering in order to derive the energy conservation inside the Dirac-Delta argument. For this end is argued that a geodesic translation along the Bloch-like sphere ...
Fabrication and analysis of self-assembled photonic crystals structures
(IEEE, 2007-01-01)
This paper presents the fabrication and analysis of a three-dimensional FCC photonic crystal (PhC) based on a self-assembly synthesis of monodispersive latex spheres. Experimental optical characterization, achieved by ...
