Abstract:
In this work, electrical transport properties and electrochemical hydrogen storage properties of a cubic spinel In(4)SnS(8) hierarchical nanostructure were investigated. A simple single layer device exhibits non-linear current-voltage (I-V) characteristics. The detailed electrical transport properties of the sample indicated that the conduction mechanism varied in different external voltage regions. Derived from the typical spinel system of the A[B(2)]X(4) (A: Zn, Cu, Sn, B: In, Ga, X: S, Se) ternary chalcogenides, this thiospinel compound also shows high electrochemical hydrogen storage of 127 mAh g(-1) and its mechanism is discussed.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
