Summary: RuNPs stabilised by a polymer immobilised ionic liquid derived from co-polymerisation of a PEG -substituted imidazolium-based styrene monomer and diphenyl(4-vinylphenyl)phosphine oxide, RuNP@O = PPh2-PEGPIILS, (2) is a highly efficient and selective catalyst for the partial reduction of nitroarenes to N-arylhydroxylamines using hydrazine hydrate. The catalyst showed near quantitative conversion to N-phenylhydroxylamine with > 99% selectivity after only 2 hours at 25 degrees C in ethanol under an inert atmosphere using 0.1 mol% catalyst. It exhibited a significantly higher initial turnover frequency (TOF) compared to 5 wt% Ru/C, making it a promising catalyst for this reaction.

Summary: In this study, a bifunctional catalyst for CO2RR and ORR reactions in aqueous Zn-air batteries (ZAB) was developed. The catalyst, consisting of atomically dispersed niobium anchored onto N-doped ordered mesoporous carbon (Nb-N-C), exhibited high activity for CO2RR, ORR, and ZAB, thanks to the high Nb atom-utilization efficiency and ordered mesoporous structure. Furthermore, the self-powered CO2 electrolysis system showed promising performance with continuous CO2 conversion.

Summary: This study reports a new method for electrochemical reduction of CO2 to formate using metal-organic frameworks (MOFs). Two new N,O-coordinated Zn-MOFs were constructed and showed high selectivity and efficiency for formate production in the CO2RR. These MOFs exhibited faradaic efficiencies of more than 60%, with the self-penetration structure of FJU-127-CH3 achieving a superior formate faradaic efficiency of 90.2% at -1.57 V vs. RHE compared to the common pillared-layer structure of FJU-127-NH2. This work proposes an effective strategy for altering the selectivity of electrocatalytic CO2RR.

Summary: Despite being well-known for their photochemical properties and industrial value, the use of nitroarenes as a productive photochemical handle in organic synthesis has been relatively unexplored. In this study, we report the design and application of a sulfinate-nitroarene electron donor-acceptor (EDA) complex, which enabled the first light mediated catalyst-free synthesis of N-hydroxy-sulfonamides. The EDA complex was characterized spectroscopically and studied using DFT and TD-DFT calculations. A total of 32 examples with electron withdrawing and electron donating groups were synthesized under oxygen- and water-tolerant conditions.

Summary: We demonstrated a facile pyrolysis method for synthesizing nitrogen-doped carbon-supported NiFe alloys (NiFe-NC) that exhibit excellent electrocatalytic activity for both CO2 reduction reaction (CO2RR) and oxygen reduction reaction (ORR). The NiFe-NC catalyst showed unprecedented CO2RR activity with a high CO faradaic efficiency and achieved a industrial current density and CO FE comparable to commercial catalysts for CO2RR. It also demonstrated impressive ORR performance comparable to commercial Pt/C catalysts. Moreover, the NiFe-NC was successfully used as a cathode material in Zn-air batteries and showed high power density. A self-driven CO2 flow electrolysis system powered by two series-connected NiFe-NC-based Zn-air batteries was designed and showed high efficiency in converting CO2 to CO. The results of this study provide insights for the development of efficient electrocatalysts for energy conversion and storage.

Summary: This work evaluates the potential of new water cluster-based ion beams for improving the capabilities of secondary ion mass spectrometry for in situ lipidomics. It found that using water clusters with carbon dioxide can lead to a more substantial signal increase in positive ion mode. Additionally, the use of water primary ion beam allowed ToF-SIMS results to approach those from MALDI, enabling the imaging of LPC lipids and other lipids that have been difficult to detect during SIMS analyses.

Summary: This study determined the structures and solvation evolution of size-selected Zn+(H2O)(n) (n = 2-35) complexes using infrared multiple photon photodissociation (IRMPD) spectroscopy and density functional theory. The coordination number of 3 was observed, even for larger clusters, due to repulsion from the Zn+ valence 4s electron. Spectrally distinct single- and double-acceptor sites were found for medium-sized clusters, while larger clusters showed increased second and third coordination sphere ligands in the hydrogen bonding region. No evidence of a solvated, six-fold coordinated Zn2+ ion/solvated electron pair was present in the spectra.

Summary: This study investigates the impact of transition metal single atoms on CO2 photoreduction on TiO2 photocatalysts, using a combination of material design, spectroscopic analyses, and theoretical studies. It was found that the electronic interaction between single Cu atoms and TiO2 affects the reducibility of the surface, leading to spontaneous formation of O vacancies near Cu atoms, which cooperatively stabilize CO2 intermediates. Optimized Cu-1/TiO2 photocatalysts exhibit a 66-fold enhancement in CO2 photoreduction performance compared to pristine TiO2, showing the importance of uniform distribution of single atoms in enhancing photocatalytic processes.

Summary: The researchers have developed a tubular-shaped nitrogen-boron-carbon catalyst (C-BN@600) derived from an ionic liquid and metal-organic framework composite, which was used as the cathode catalyst in a rechargeable zinc-carbon dioxide battery. The C-BN@600 catalyst exhibited excellent activity for electrochemical CO2 reduction to methanol with a Faradaic efficiency of 74% and a yield rate of 2665 μg h-1 mg-cat.1. The battery continuously consumes CO2 and electrochemically converts it to methanol during discharge, while simultaneously generating electrical energy, demonstrating a high energy density of 330 Wh kg-1 and a power density of 5.42 mW cm-2. It maintained stability for more than 12 days (>300 h, 800 cycles) at 1 mA cm-2, offering a dual-purpose platform for CO2 reduction and energy storage.

Summary: This study examines the role of phraseological complexity measures in predicting the writing quality of low- and intermediate-level second language learners, compared to more traditional syntactic and lexical complexity measures. The findings suggest that phraseological, syntactic, and lexical complexity measures each contribute to explaining the variance in writing scores. Phraseological complexity is found to be an independent dimension of L2 complexity.

Summary: This study investigates the relationships among word processing, working memory, and second language reading comprehension performance. The results show that second language reading comprehension performance is related to the first fixation duration on unfamiliar words, and the first fixation duration on unfamiliar words is related to participants' working memory capacity. Moreover, the effect of first fixation duration on unfamiliar words on second language reading comprehension performance can be moderated by participants' working memory capacity.
