Summary: This work reports the first catalyzed synthesis of d-block metal-metal bonded complexes. The treatment of terminal zinc hydrides in the presence of 5 mol% Ni(CO)(2)(PPh3)(2) afforded Zn(i)-Zn(i) bonded compounds in high isolated yields with concomitant elimination of dihydrogen. Stoichiometric reactions, kinetic studies and DFT calculations were conducted to elucidate the reaction mechanism.

Summary: A highly self-adaptable PDMS/MMT film was developed to regulate the process of zinc deposition in rechargeable aqueous zinc-ion batteries. The film achieved targeted-capture and ordered-deposition of zinc ions, leading to high coulombic efficiency and an ultra-long cycle life compared to bare zinc anodes. This strategy provides an effective approach to develop a stable Zn metal anode for aqueous rechargeable batteries.

Summary: This study successfully prepared a series of alloyed Cd-Zn-S quantum dots-embedded glasses (QDEGs) with controlled emission spectra ranging from green to red. The well-dispersed quantum dots were achieved by cracking the solid-solution precursors during the sintering process. The Cd0.5Zn0.5S QDEG exhibited a high quantum yield of 30%, highlighting its potential for efficient red-emissive applications.

Summary: Catalytic asymmetric transformation is a powerful strategy for synthesizing diverse nonracemic molecular entities. Carboxylic acids have been explored as building blocks in this area, and significant advancements have been made in the last three decades. They can act as both C- and O-nucleophiles, as well as electrophiles, in asymmetric reactions under catalytic conditions.

Summary: Scanning electron microscopy and atomic force microscopy images of droplet landing sites are correlated with the electrocatalytic activity for the oxygen evolution reaction in alkaline electrolyte of hexagonal spinel Co3O4 nanoparticles derived using scanning electrochemical cell microscopy. The turnover frequency (TOF) of surface Co atoms is used to deconvolute the intrinsic catalytic activity of individual crystal facets of the hexagonal Co3O4 spinel particle. The top surface exposing 111 crystal planes showed a thickness-dependent TOF, while the edge of the particle exposing (110) planes showed a higher average TOF and no correlation with particle thickness.

Summary: By using operando quick X-ray absorption fine structure spectroscopy and unsupervised/supervised machine learning methods, we can unveil the real active species and active states in bimetallic transition-metal oxide catalysts. Through principal component analysis and artificial neural network analysis, we can track the evolution of tetrahedrally and octahedrally coordinated species and understand the chemical changes and phase transitions taking place in CoxFe3-xO4 catalysts.

Summary: Oxidative addition reactions of LZnH with L1Si and L2SiNMe2 yielded L1Si(H)-ZnL (1) and LH2Si(NMe2)ZnL (3), while the reaction with L2SiCl proceeded with H/Cl ligand exchange and the formation of L2Si(H)-Zn(Cl)L (2). Protonation reaction of 1 with H-(OEt2)2BArF4 gave LS(H)-ZnL (4). The nature of the Zn-Si bond in 1-4 was evaluated by quantum chemical calculations, showing that the Si-Zn bond in 1 and 3 is covalent, while those in 2 and 4 are better described as dative bonds.

Summary: Based on DFT calculations, LGa(P2OC)cAAC 2 possesses a delocalized p-type HOMO and p*-type LUMO due to the presence of a 1,2-diphospha-1,3-butadiene moiety. Reaction of 2 with KC8 and dibenzo-18-crown-6 led to the isolation of [LGa(P2OC)cAAC][K(DB-18-c-6)] 3[K(DB-18-c-6] containing the 1,2-diphospha-1,3-butadiene radical anion 3*. Further reactions of 3 with [Fc][B(C6F5)(4)] and TEMPO yielded 2 and [L-HGa-(P2OC)cAAC][K(DB-18-c-6)] 4[K(DB-18-c-6] respectively, with the latter containing the 1,2-diphospha-1,3-butadiene anion 4-. The structures of 2, 3[K(DB-18-c-6], and 4[K(DB-18-c-6] were determined using single crystal X-ray diffraction (sc-XRD).

Summary: Insertion and functionalization of gallasilylenes into the cyclo-E-5 rings of [Cp*Fe(?(5)-E-5)] (E = P, As) have been reported. The reaction results in E-E/Si-Ga bond cleavage and the insertion of the silylene in the cyclo-E-5 rings. The isolated complexes represent rare examples of mixed group 13/14 iron polypnictogenides, which can only be synthesized by utilizing the cooperativity of gallatetrylenes.
