TL;DR: It is reported that a phosphomimetic mutant of cy tochrome c exhibits enhanced dynamics, which could be responsible for the observed differences in cytochrome c functionality in oxidative stress and cell death, and becomes a target for further development of robust therapeutic approaches.
Rapid Monitoring of the Nature and Interconversion of Supported Catalyst Phases and of Their Influence upon Performance: CO Oxidation to CO2 by γ‐Al2O3 Supported Rh Catalysts
TL;DR: Spatially and temporally resolved energy-dispersive EXAFS (EDE) has been utilised in situ to study supported Rh nanoparticles during CO oxidation by O2 under plug-flow conditions and induces structural lability that influences catalytic behaviour.

Abstract: The analysis of the extended X-ray absorption fine structure (EXAFS) spectra of dilute aqueous solutions (0.1 M) of Cr(NO3)3 and Rh(NO3)3 was performed using several approaches. Single- and multiple-scattering (SS and MS) phenomena were taken into account to establish the relative importance of their possible contributions to the long distance peak (R ≈ 4 A). XANADU, FEFF, and FEFFIT codes were employed to analyze the data. The first approach considered the single-scattering contribution due to the existence of a well-defined second hydration shell around both of the trivalent cations, Cr3+ and Rh3+. The second approach evaluated the contribution due to the multiple-scattering phenomena inside the first hydration shell. Comparison of experimental spectra with the calculated ones considering either one or both of the contributions led us to conclude that both contributions were significant in the high-R region of the spectra. This study supports our previous hypothesis which states that the second hydratio...
