Summary: In the face of rising atmospheric carbon dioxide (CO2) emissions from fossil fuel combustion, the hydrogen evolution reaction (HER) continues to attract attention as a method for generating a carbon-neutral energy source. This study reports the electrochemical analysis of a molecular nickel(ii) complex, which acts as an efficient electrocatalyst for the HER with high faradaic efficiency and turnover frequencies. Computational studies suggest that non-covalent interactions between the proton donor and ligand heteroatoms play a crucial role in the electrocatalytic HER mechanism.

Summary: This study reports the synthesis, characterization, and in vivo evaluation of a series of rhenium tricarbonyl complexes containing 5- and 6-(halomethyl)-2,2'-bipyridine ligands. The aim was to investigate the role of a reactive halomethyl substituent on the diimine ligand system in the design of effective and non-toxic anticancer agents. Compounds capable of undergoing ligand-based alkylating reactions exhibited significant antiproliferative activity against colorectal and pancreatic cell lines. One specific compound (5-(chloromethyl)-2,2'-bipyridine derivative) displayed significant inhibition of pancreatic tumor growth in vivo in zebrafish-Panc-1 xenografts at a concentration of 8 μM, lower than its in vitro IC50 values, and also inhibited in vivo cancer cell dissemination.

Summary: The first nickel-catalyzed highly enantioselective reductive Ullmann coupling of ortho-chlorinated aryl aldehyde was achieved under mild reaction conditions using a chiral 2,2'-bipyridine ligand (+)-DTB-SBpy, resulting in the synthesis of axially chiral biphenyl or binaphthyl dials with high yields and enantioselectivities. The versatility of the products as common synthetic intermediates for diverse axially chiral ligands, catalysts, and functional molecules was demonstrated through short-step transformations. Additionally, this protocol enabled the concise and highly enantioselective formal total synthesis of biologically active natural products.

Summary: Membrane transport proteins have important regulatory functions in biology and can respond to environmental stimuli. Using bis(thio)ureas derived from stiff-stilbene, photocontrol of transmembrane transport and electric potential has been demonstrated through UV-vis and H-1 NMR spectroscopy. The (Z)-isomers show stronger binding properties and are more active in transmembrane transport compared to the (E)-isomers.

Summary: In this study, a Co-based complex was utilized for the reduction of O2 to H2O, showing selectivity for the four-electron/four-proton reduction product. The key selectivity difference was found to arise from increased favorability of protonation at the distal O position of the key intermediate Co(III)-hydroperoxide. Interestingly, no product selectivity dependence was observed with respect to the presence of pyridine during catalysis.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing. This work provides a good reference for designing fluorescent MOF probes containing CuI molecules.

Summary: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.

Summary: Developing low-cost and self-supported bifunctional catalysts is crucial for highly efficient water splitting devices. In this study, nano-NiFe2O4 was directly grown onto iron foil surface and Sn4+ was introduced into the NiFe2O4. The resulting Sn-NiFe2O4/IF showed low overpotentials and high current densities during oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), making it a promising catalyst for large-scale hydrogen production.
