Summary: New tunable aryl alkyl ionic liquids (TAAILs) based on imidazolium containing weakly coordinating anion [Ga(C2F5)(4)](-) were investigated for their viscosity, conductivity, and electrochemical stability. The gallate-TAAILs showed stability even at high electrochemical potentials and are considered promising candidates for electrolytes in electrochemical applications. More details can be found in the communication by B. Hoge, T. Strassner, et al. (DOI: 10.1002/chem.202102097).

Summary: This article reviews the recent advances in the synthesis and applications of ferrocene-fused nitrogen heterocycles. The transfer of powerful transition-metal-catalyzed methodologies for C-H bond functionalization of benzene derivatives to ferrocene has played a significant role in this field.

Summary: We demonstrate that the 1s22s22p1/2 - 1s2s22p21/2 transition in Pb77+ emitted during the dielectronic recombination of Pb78+ exhibits strong polarization, despite being an intrinsically unpolarized J = 1/2 to 1/2 transition. This unexpected polarization is attributed to quantum interference with radiative recombination. The interference effect, previously studied on an asymmetric resonance profile, is shown to have a significant impact on polarization even for a nearly symmetric resonance, suggesting a small interference.

Summary: Ultraviolet ozone flushing (UVO) is used to oxidize the NiOx hole-transport layer, activating the Ni3+ at the top of the NiOx film and enhancing its electrical properties and hole extraction ability. Sequential deposition of perovskites leads to the formation of residual PbI2 at the bottom interface, preventing direct contact between the NiOx film and the perovskite layer and avoiding NiOx-related chemical reactions.

Summary: The dynamic behavior of ceria-supported Pd single atoms, clusters, and nanoparticles during CO oxidation was investigated using operando spectroscopy. The catalytic role of different Pd species was elucidated through a combination of in situ spectroscopy with transient and steady-state kinetic analysis, revealing that highly dispersed Pd-oxo species and interfacial Pd sites catalyze low-temperature CO oxidation, while metallic Pd contributes to the activity at elevated temperature.

Summary: The double-shelled hollow PMo12-SiO2@N-C anode material achieves excellent lithium storage, with the N-C outer shell improving electronic conductivity and promoting dispersion of PMo12 clusters, and the SiO2 inner shell efficiently avoiding loss of active components. The hollow structure helps buffer volume expansion and accelerate Li+ diffusion during lithiation/delithiation.

Summary: The optical fluorescent pH sensors based on positively charged silica microparticles containing anionic pyranine molecules were developed using a modified Stober method, ensuring overly pH-sensitive nature of pyranine and long-term stability through silica shell coating. These cytocompatible ratiometric pH sensors can be individually observed and are suitable for pH sensing and tracking applications.

Summary: A new method is proposed to improve the IRI2016 vertical electron density profile by ingesting in situ Ne values from Swarm A, B and C. Validation of the method showed improvements in 63% of observed epochs, with similar fractions of improvements on quiet and storm days. The change in Root-Mean-Square-Error was not dependent on distance or difference in predicted hmF2.

Summary: This study presents the synthesis of in-fjord substituted expanded helicenes and estimates their inversion barriers through state-of-the-art quantum calculations. The energetic profile of the inversions is found to be significantly influenced by the interplay of steric and attractive London dispersion interactions. More details can be found in the Full Paper by R. A. Mata, M. Alcarazo, et al. (DOI: 10.1002/chem.202102585).
