X-ray photoelectron spectra of metal complexes of substituted 2,4-pentanediones

Surface chemistry of the iron tetraazamacrocycle on the aminopropyl‐modified surface of oxidized n‐Si(100) by AFM and XPS

“…32 The second doublet with higher Fe 2p binding energies is probably due to the presence of some Fe(III)TIM complex because both the high binding energy and spin-orbit splitting are close to those of Fe(III) systems. 33 It is important to note that electron paramagnetic resonance or electronic spectroscopy observed no oxidation product in the adsorption solutions or FeTIM complex powder during 3 days in air. From this we infer that oxidation of the surface-bound FeTIM took place due to reaction of the film with air.…”

XPS study of the electron structure of heterometallic trinuclear complexes Fe2M(μ3-O)(μ-Piv)6(HPiv)3 (MMn, Co, Ni)

“…X-ray photoelectron spectroscopy (XPS) is a powerful tool to study electron structure of complexes. XPS studies allow one to obtain the information both on chemical state and electronic properties of elements, and estimate magnetic characteristics of compounds, as well as to extend our knowledge on the nature of metal-ligand bonding [1][2][3][4]. Application of XPS for the studies of heterometallic complexes of 3d-metals gives a possibility to obtain the information on electronic structure of those compounds, which can be prospective for catalysis, optics, as building blocks when designing porous structures, as well as useful precursors for the oxide materials.…”

Tribological evaluation of contact-charged electrostatic spray lubrication as a new near-dry machining technique

“…14(h), new peaks also appear on the Fe 2p spectrum of the worn surface lubricated by MQL. According to Srivastava and Badrinarayanan [46], the binding energy of 712.6 eV should belong to the Fe 2p 3/2 for R-COOFe (metal soap). In Table 2, the relative atomic contents of O and Fe on the worn surface lubricated by MQL are 6.30% and 4.98% higher than those on the AISI 52100 steel surface, respectively, and the relative atomic content of C is 11.28% lower than that on the steel surface.…”
