A unified relationship between the experimental formation constants and the ligand(s)-to-metal charge transfer values of versatile ligand complexes of late transition series first-row bivalent metal ions is uncovered. The latter property not only explicates the Irving–Williams series but also rationali...

摘要: Magnetic and structural properties of new graphite compounds with ReF6 and TcF6, together with previous data, provide evidence for the existence of a correlation between the layer spacing and the charge transfer for the metal hexafluorides.关键词:...
The charge excitation and decay pathways of two-dimensional heteroatomic quantum dots (QDs) are affected by the quantum confinement effect, bandgap structure and strong exciton binding energy. Recently, semiconducting transition metal dichalcogenides (TMDs) have been intensively studied; however, the charg...
Most of the light energy is absorbed by the metal and die- lectric layers to generate the evanescent wave which propagates along the interface and penetrates into the sens- ing film. When the occurs as shown in Eevqa. n(1e)s.cIenntowrdaevretoveacntoalryksex mouartcNh-elsayweirthsttr...

In realistic situations, the compounds are always in contact with a reactive environment, e.g., in an O2(plus H2) atmosphere. Under such conditions, the oxidation of a metal (X) is described by the reaction path $$n\cdot {\mathrm{X}} + \frac{m}{2}\cdot {\mathrm{O}}_2 + \fra...
