Abstract
Stabilization of ions in exotic oxidation states is beneficial for the development of new materials for green energy technologies. Exotic Mn1+ was proposed to play a role in the function of sodium-based Prussian blue analogues (PBA) batteries, a highly sought-out technology for industrial energy storage. Here, we report the detailed electronic structure characterization of uncharged and charged sodium-based manganese hexacyanomanganate anodes via Mn K-edge X-ray absorption spectroscopy (XAS), Kβ nonresonant X-ray emission (XES), and resonant inelastic X-ray scattering (RIXS). The latter allowed us to obtain site-selective XANES information about two distinct Mn centers. The obtained spectroscopic data represent the first electronic structure characterization of low-spin Mn1+ using hard X-ray RIXS and XES and allowed us to confirm its role in anode reduction. Our experimental approach can be expanded to analysis of analogues with other 3d transition metals broadening the application of exotic ionic states in materials engineering.

Abstract
Herein, we show that coupling boron with cobalt oxide tunes its structure and significantly boost its electrocatalytic performance for the oxygen evolution reaction (OER). Through a simple precipitation and thermal treatment process, a series of Co-B oxides with tunable morphologies and textural parameters were prepared. Detailed structural analysis supported first the formation of an disordered and partially amorphous material with nanosized Co3 BO5 and/or Co2 B2 O6 being present on the local atomic scale. The boron modulation resulted in a superior OER reactivity by delivering a large current and an overpotential of 338 mV to reach a current density of 10 mA cm-2 in 1 M KOH electrolyte. Identical location transmission electron microscopy and in situ electrochemical Raman spectroscopy studies revealed alteration and surface re-construction of materials, and formation of CoO2 and (oxy)hydroxide intermediate, which were found to be highly dependent on crystallinity of the samples.

Abstract
The Inner Shell Spectroscopy (ISS) beamline on the 8-ID station at the National Synchrotron Light Source II (NSLS-II), Upton, NY, USA, is a high-throughput X-ray absorption spectroscopy beamline designed for in situ, operando, and time-resolved material characterization using high monochromatic flux and scanning speed. This contribution discusses the technical specifications of the beamline in terms of optics, heat load management, monochromator motion control, and data acquisition and processing. Results of the beamline tests demonstrating the quality of the data obtainable on the instrument, possible energy scanning speeds, as well as long-term beamline stability are shown. The ability to directly control the monochromator trajectory to define the acquisition time for each spectral region is highlighted. Examples of studies performed on the beamline are presented. The paper is concluded with a brief outlook for future developments.

Abstract
![]()
A series of organometallic
copper complexes in formal oxidation
states ranging from +1 to +3 have been characterized by a combination
of Cu K-edge X-ray absorption (XAS) and Cu Kβ valence-to-core
X-ray emission spectroscopies (VtC XES). Each formal oxidation state
exhibits distinctly different XAS and VtC XES transition energies
due to the differences in the Cu Zeff, concomitant with
changes in physical oxidation state from +1 to +2 to +3. Herein, we
demonstrate the sensitivity of XAS and VtC XES to the physical oxidation
states of a series of N-heterocyclic carbene (NHC) ligated organocopper
complexes. We then extend these methods to the study of the [Cu(CF3)4]− ion. Complemented by computational
methods, the observed spectral transitions are correlated with the
electronic structure of the complexes and the Cu Zeff.
These calculations demonstrate that a contraction of the Cu 1s orbitals
to deeper binding energy upon oxidation of the Cu center manifests
spectroscopically as a stepped increase in the energy of both XAS
and Kβ2,5 emission features with increasing formal
oxidation state within the [Cun+(NHC2)]n+ series. The newly synthesized Cu(III) cation
[CuIII(NHC4)]3+ exhibits spectroscopic
features and an electronic structure remarkably similar to [Cu(CF3)4]−, supporting a physical oxidation
state assignment of low-spin d8 Cu(III) for [Cu(CF3)4]−. Combining XAS and VtC XES
further demonstrates the necessity of combining multiple spectroscopies
when investigating the electronic structures of highly covalent copper
complexes, providing a template for future investigations into both
synthetic and biological metal centers.
