X-ray photoelectron and X-ray emission study of the electronic structure of hexanuclear Mn(II,III) pivalate complexes

A Universal Method for Regulating Carbon Microcrystalline Structure for High-Capacity Sodium Storage: Binding Energy As Descriptor

“…High-resolution Mn 2p spectroscopy (Figure d) reveals the existence of Mn 2+ (640.8 eV), Mn 3+ (642.1 eV), and Mn 4+ (643.6 eV) . The existence of high-energy satellite structures with an energy of ∼646 eV indicates the typical exchange interaction of the d5 configuration . High-resolution C 1s spectra (Figure e) show that CC (283.5 eV), C–C (284.4 eV), and CO (289.1 eV) are present in all three samples .…”

“…55 The existence of high-energy satellite structures with an energy of ∼646 eV indicates the typical exchange interaction of the d5 configuration. 56 Highresolution C 1s spectra (Figure 3e) show that C�C (283.5 eV), C−C (284.4 eV), and C�O (289.1 eV) are present in all three samples. 3 However, PAHC/Mn has a −C−O−C− structure, while PAHC mainly has a C−O structure.…”

The effect of hydrophobic chains on retarding performance of retarding acids

“…We did X-ray photoelectron spectroscopy (XPS, Escalab 250Xi England) analysis to determine the elemental composition of the substances 37,38 on the rock surface aer retarding acid interacted with rock. Fig.…”
