Hard carbon (HC) has emerged as a promising anode material for sodium-ion batteries (SIBs) owing to its low cost, abundant renewable resources, and high specific capacity. However, its practical application is significantly hindered by the severe initial irreversible capacity loss resulting from sodium consumption during the first cycle. To address this issue, a variety of presodiation strategies have been developed to compensate for the sodium loss and improve the initial coulombic efficiency.

Despite great advances in decarbonylation of aldehydes using noble metals, the reaction is largely limited to high reaction temperatures and displays poor functional group tolerance. Herein, we report photo-irradiated decarbonylation of aldehydes, promoted by -W(N)(dppe), at room temperature. A wide range of substrates with diverse functional groups underwent decarbonylation efficiently to give the corresponding arene and alkane products in moderate to high yields.

Super austenitic stainless steels (SASS) face challenges like galvanic corrosion and antibacterial performance when welded to carbon steel (Q235) in marine environments. This study demonstrates that adding 1.0 wt% cerium (Ce) to SASS refines the heat-affected zone (HAZ) grain structure (from 7 μm to 2 μm), suppresses detrimental σ-phase precipitation, and forms a dense oxide film.

The study of electrochemical oxidations has wide-ranging implications, from the development of new electrocatalysts for fuel cells for energy conversion, to the synthesis of fine chemicals. 2,2,6,6-Tetramethylpiperidine-1-oxyl (TEMPO) has been used for decades as a sustainable, metal-free mediator for chemical oxidations and is now being used for electrochemical oxidations. We describe here a novel approach to TEMPO-mediated electrooxidations, in which the chemical input and waste generated during electrooxidations of alcohols are minimized by using a multifunctional room temperature ionic liquid (RTIL) to facilitate flow electrosynthesis.

Beyond the conventional carbon-centered chirality, catalytic asymmetric transformations of isocyanides have recently emerged as a powerful strategy for the efficient synthesis of structurally diverse scaffolds featuring axial, planar, helical, and inherent chirality. Herein, we summarize the exciting achievements in this rapidly evolving field. These elegant examples have been organized and presented based on the reaction type as well as the resulting chirality form.
