Resolving surface chemical states in XPS analysis of first row transition metals, oxides and hydroxides: Sc, Ti, V, Cu and Zn
TL;DR: Biesinger et al. as mentioned in this paper proposed a more consistent and effective approach to curve fitting based on a combination of standard spectra from quality reference samples, a survey of appropriate literature databases and/or a compilation of literature references and specific literature references where fitting procedures are available.

Direct evidence of boosted oxygen evolution over perovskite by enhanced lattice oxygen participation.
Yangli Pan,Yangli Pan,Xiaomin Xu,Yijun Zhong,Lei Ge,Yubo Chen,Jean-Pierre Veder,Daqin Guan,Ryan O'Hayre,Mengran Li,Guoxiong Wang,Hao Wang,Wei Zhou,Zongping Shao,Zongping Shao +14 more
TL;DR: The extent to which the participation of lattice oxygen can contribute to the OER is distinguished through the rational design of a model system of silicon-incorporated strontium cobaltite perovskite electrocatalysts with similar surface transition metal properties yet different oxygen diffusion rates.

Probing the Origin of Enhanced Stability of AlPO4 Nanoparticle Coated LiCoO2 during Cycling to High Voltages: Combined XRD and XPS Studies
TL;DR: In this paper, X-ray powder diffraction analyses revealed that select peak broadening was observed for cycled bare electrodes suggesting that structural damage to LixCoO2 was introduced upon cycling.

Microstructure of LiCoO2 with and without “AlPO4” Nanoparticle Coating: Combined STEM and XPS Studies
TL;DR: In this paper, AlPO4-coated LiCoO2 was shown to exhibit markedly improved capacity retention relative to bare LiCo2 upon cycling to 4.7 V. Scanning and transmission electron microscopy imaging showed that the...

TL;DR: Electrochemical capacitors that have a liquefied gas electrolyte based on difluoromethane (CH2F2) have an exceptionally wide operation temperature from –78° to +65°C, with similar resistance and capacitance to conventional devices, and the low melting points of the solvents studied could allow for substantial improvements in device operation at low temperatures.
