In this communication, we report an innovative electrode design of 3D hierachical TiO2 urchin assembled with a hollow TiO2 spheres core and radial TiO2 nanorod shell prepared via a facile colloid template route combined with atomic layer deposition and a hydrothermal growth process. The periodically hierarchical TiO2 urchin exhibits excellent omnidirectional anti-reflectance properties in a wid...

Pistachio is one of the most important horticultural products of Iran with special economic importance. In average 70% of Iran pistachio are exported. Aflatoxin is secondary metabolites of fungus such as Aspergillus flavus and A. parasiticus. If favorite condition is prepared for stabilization of fungi spores producing Aflatoxin, the first pistachio contamination to Aflatoxin occurs in orchard....

In this work, we present a novel method to reveal azimuthal whispering gallery modes (WGMs) in a spherical microcavity coated with a nano-meter thick polyelectrolyte shell and one monolayer of CdTe semiconductor quantum dots. The new approach in this experiment is based on the deformation of the spherical shape in a non-contact way using the radiation pressure from a laser beam, which causes th...

The pf-shell (i.e. the 2p 1 2 -2p 3 2 -1f 5 2 shell) is important for a variety of problems in nuclear structure, however, the study of this shell has been hindered by the huge size of the shell model space. In recent years there have been studies by using the Monte-Carlo shell model [1] and that based on the pseudo-SU(4) symmetry model [2]. The original Wigner Supermultiplet SU(4) model[3] is ...

Pigmy and soft-dipole states in light drip-line nuclei are investigated by large-scale shell model calculations. Large E1 strength is found in the low-excitation-energy region below 5MeV in halo or skin nuclei such as 11Li, 12Be, and 13O. Both the effects of the extended halo or skin wave functions and the coherence in the transition amplitudes are important for enhancing the E1 strength. The p...

Results of shell-model calculations for lower f p-shell nuclei show that SU~3! symmetry breaking in this region is driven by the single-particle spin-orbit splitting. However, even though states of the yrast band exhibit SU~3! symmetry breaking, the results also show that the yrast band B(E2) values are insensitive to this fragmentation of the SU~3! symmetry; specifically, the quadrupole collec...

Fermion localization functions are used to discuss electronic and nucleonic shell structure effects in the superheavy element oganesson, the heaviest element discovered to date. Spin-orbit splitting in the 7p electronic shell becomes so large (∼10  eV) that Og is expected to show uniform-gas-like behavior in the valence region with a rather large dipole polarizability compared to the lighter ra...

Highly-effective sustainable hydrogen production from ethanol and water was achieved in a tubular dense mixed-conducting oxygen permeable membrane reactor, in which water splitting took place at the tube side of the membrane and oxidative steam reforming of ethanol occurred at the shell side simultaneously.

Highly dispersed rhodium nanoparticles (1.7 +/- 0.3 nm) prepared by a liquid-phase reduction method were loaded on a solid solution of GaN and ZnO without forming aggregates, achieving improved activity for visible-light-driven overall water splitting when the nanoparticles are coated with a chromia shell.

We report magnetic field spectroscopy measurements in carbon nanotube quantum dots exhibiting fourfold shell structure in the energy level spectrum. The magnetic field induces a large splitting between the two orbital states of each shell, demonstrating their opposite magnetic moment and determining transitions in the spin and orbital configuration of the quantum dot ground state. We use inelas...
