Summary: Thiol-containing amino acids have been extensively studied as chelating ligands, forming coordination compounds with various metal elements and exhibiting a capacity to form multinuclear structures. Recent research has demonstrated that the use of metal complexes with thiol-containing amino acids allows for the selective introduction of secondary metal ions, enabling the rational design of multinuclear and metallosupramolecular coordination compounds.

Summary: The rational design of novel self-assembled nanomaterials based on peptides is a challenge in modern chemistry. A hierarchical approach for constructing nanofibrils using alpha,beta-peptide foldamers was proposed, with the introduction of a helix-promoting residue leading to increased conformational stability. Analytical ultracentrifugation confirmed the oligomerization state in solution, while AFM and TEM techniques showed the formation of well-defined nanofibrils directed by additional interactions between coiled-coil-like structures.

Summary: This study investigates the structural and mechanical differences between chiral and racemic crystals of two analogous molecules. The molecular and crystal structures of the analogues were compared with known chiral-racemic crystal pairs. The Young's moduli of the crystals show that racemic crystals have larger values and their thermal response agrees with the temperature dependence of lattice dynamics.

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.
