This study reports an evaluation on the scope of X‐ray photoelectron spectroscopy (XPS) to obtain information for coordination chemistry transition metal (T n ) hexacyanometallates, T x A z [M m (CN) 6 ] y where nx + = (6 – ), is alkaline charge‐compensating cation, and M a with maximum electrons in its d orbitals. XPS provides elegant picture role CN π‐back bonding effect determine charge density N atom and, from this fact, ions form polymers. appears be able discriminate between octahedral...

Abstract This study evaluates the interaction of mesoporous carbon (MC) and nitrogen doped (NMC) with Nickel prussian blue analogues (Ni‐PBA) its effect on electrochemical properties energy storage. The Raman, IR, Mossbauer XPS results reveal that MC‐NiPBA composite exhibited a large modification to covalent character an increase in defects carbonaceous material. latter is associated oxidation sites reduction iron hexacyanoferrate during synthesis, which charge subtraction Fe (Low Spin)...
The charge density accumulated at the CN 5σ orbital, via π-back bonding interaction, determines crystal field splitting for Fe( ii ) atom and temperature where spin transition is observed.
Superconducting niobium serves as a key enabling material for superconducting radio frequency (SRF) technology well quantum computing devices. At room temperature, hydrogen commonly occupies tetragonal sites in the Nb lattice metal (M)-gas (H) phase. When temperature is decreased, however, solid solution of Nb-H starts to be precipitated. In this study, we show first identified topographical features associated with nanometer-size hydride phase (Nb1-xHx) precipitates on metallic using...
Superconducting niobium serves as a key enabling material for superconducting radio frequency (SRF) technology well quantum computing devices. Niobium has high propensity the uptake of hydrogen. At room temperature, hydrogen commonly occupies tetragonal sites in Nb lattice metal (M)–gas (H) phase. When temperature is decreased, however, solid solution Nb-H begins to precipitate.

Abstract Coordination polymers have received considerable attention in recent years as electrocatalytic materials for the construction of electrochemical sensors. This is due to their high sensitivity and selectivity towards detection various molecules, particularly pollutants metabolites, which commonly appear low concentrations complex matrices. In this work, an sensor was performed phenylhydrazine, a strong pollutant, based on mixed Ni 2+ Co transition metal nitroprusside (NiCoNP). NiCoNP...
