Summary: In this study, a heterostructured electrocatalyst is developed for overall water splitting. The combination of Co-FeOOH and Ir-Co(OH)F creates abundant active sites, accelerates reaction kinetics, improves charge transfer abilities, and optimizes adsorption energies, leading to enhanced catalytic activity. The electrocatalyst exhibits low overpotentials and excellent stability for OER, HER, and overall water splitting in 1.0 M KOH electrolyte. This research provides a promising strategy for advanced heterostructured bifunctional electrocatalysts in alkaline water splitting.

Summary: Experimental and theoretical studies have found that the Li + HF and Li + HCl reactions share similar kinematics but exhibit significant differences in dynamics at low collision energies. The correlation between angular momenta involved in the reactions and the relationship between the rotational motion of the product and the orbital angular momentum are also investigated.

Summary: A cascade [4+3] annulation of o-alkenyl bromoarenes and o-bromoaniline derivatives is reported, leading to the synthesis of various dibenzo[b,f]azepines with substitutions on the 10/11 position in moderate to high yields. The versatility of this protocol is demonstrated through the preparation of a precursor for the drug molecule oxcarbazepine, gram-scale synthesis, and two product transformations. Unlike previous amination/Heck sequences, this cascade process follows a C(vinyl), C(aryl)-palladacycle involved pathway.

Summary: Chemical reactions often have multiple pathways, and controlling them is important in both theoretical and practical aspects. This study focuses on the dynamics of the O + HO2 -> OH + O-2 reaction, which is crucial in atmospheric chemistry. Using a full-dimensional potential energy surface (PES) and quasi-classical trajectories, the researchers found that under thermal conditions, the reaction is dominated by a pathway that leads to vibrational excitation of the O-2 product. However, when the HO2 reactant is excited in its O-H (v(1)) vibrational mode, the reaction pathway switches to a different channel, resulting in a highly excited OH product. The implications of these dynamic effects on atmospheric chemistry are discussed.

Summary: Fe3O4 nanoparticles exhibit peroxidase-like catalytic activity primarily due to complexed hydroxyl radicals and high-valent Fe(sic)O species under acid conditions. The enzyme-like activity of Fe3O4 NPs can be rationally regulated by modulating the size, surface structure, and valence of active metal atoms according to this newly proposed nanozyme catalytic mechanism.
