Variation of the physical properties of four transition metal oxides

... compounds under investigation have zero band gaps. We have also observed several maxima and minima with similar peak for all the compounds in the conductivity plot. However, electrical conductivity of SrTMO3 (TM = Rh, Ti, Mo, Zr) raises as a result of absorbing photon energy [33]. The dielectric fun ...

If the concentration of the reactants is higher, then they will be closer together, and it won't take as long for them to come together and react ...

Hybrid superconductor junctions with diluted PtNi ferromagnetic interlayer Taras Golod

... S-N-F structure can be replaced by S-F structure with diluted F in which the superconducting state coexists with ferromagnetic. Both hybrid S-F-S and spin-valve devices put strong constrains on the F layer. Technologically the F layer should be thick enough, ∼ 10nm, to form a uniform Josephson barri ...

Ultraviolet–visible spectroscopy



Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent (near-UV and near-infrared [NIR]) ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum, molecules undergo electronic transitions. This technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.
