Summary: The study finds that Pb9Cu(PO4)(6)O crystals exhibit high insulating and optical transparent properties, ruling out the presence of superconductivity. Magnetic susceptibility measurements show the characteristic of a non-magnetic insulator, along with a small ferromagnetic component possibly originating from Cu-rich clusters in the structure.

Summary: This study reported the synthesis of a novel metal-organic capsule constructed from six pyrogallol[4]arene macrocycles, which are linked together by 16 Fe-III and 16 Co-II ions. The supramolecular structure represents the first instance of a spheroidal heterometallic nanocage assembled through a one-step metal-ligand coordination approach. The photophysical and electrochemical studies of self-assembled capsule films suggest their potential as semiconductors, displaying unexpected photoelectric conversion properties. This emergent phenomenon in discrete metal-organic supramolecular assemblies demonstrates important proof of concept through the formation of multiple heterometallic metal-metal interactions within the capsule framework.

Summary: The capability of precisely constructing bimetallic clusters with atomic accuracy provides exciting opportunities for establishing their structure-property correlations. However, the chemistry dictating the fabrication of clusters with atomic-level control has been a long-standing challenge. In this study, the factors of steric hindrance and electronic effect of ligands, the charge state of Au-25(SR)(18), and the amount of dopant were systematically investigated. The results revealed the reversible transformation between [Au19Cd3(SR)(18)](-) and Au24Cd(SR)(18) by manipulating ligands with different steric hindrances. Additionally, a novel bimetallic cluster, Au4Cd4(SR)(12), was successfully fabricated by introducing an excess amount of dopant.

Summary: We synthesized and characterized KLnSe(2) series via solid state molten flux growth method. The crystal structures were determined using single crystal x-ray diffraction, revealing a trigonal crystal system with two-dimensional layers made of edged shared LnSe(6)-octahedra. The magnetic properties indicate frustrated magnetism in the KLnSe(2) series, as Ce, Pr, and Nd do not exhibit long-range ordering below 0.4 K.

Summary: In this study, the high-pressure structural, magnetic and electrical transport characteristics of CrBr3 were investigated using various techniques. The results showed that CrBr3 underwent structural, electronic and magnetic transitions under different pressure conditions. The reversibility of these transitions was observed upon decompression. This systematic high-pressure investigation provides insights into the potential applications of CrBr3 in spintronics, magnetic and electronic devices, and improves our understanding of the physicochemical behaviors of 2D magnetic materials.

Summary: Multiferroics are advanced materials with potential applications that possess both charge polar and magnetic order, making them at the forefront of modern science. Previous studies have shown that the RECrO3 (RE = rare earth) compounds may be another rare candidate system combining ferroelectricity and magnetism. However, there are still unresolved issues causing disputes about whether RECrO3 is multiferroic or not. To address these questions, growing single crystals is a key step to obtain reliable information. This review comprehensively discusses the parent and doped ferroelectric YCrO3 compounds, including their synthesis methods, structural, magnetic, ferroelectric, dielectric, optical, and chemical properties, as well as potential applications. The review also summarizes the general results, consensuses, controversies, future research opportunities, and emerging challenges in the field.

Summary: Recent studies have revealed that some amyloid-like structures are reversible and derived from protein low-complexity domains involved in cellular metabolism. The finding of unique structural features of reversible amyloid fibrils suggests the involvement of intraresidue interactions known as C5 hydrogen-bonds in stabilizing these structures.

Summary: In 2019, a unique Fe-II complex with a low-spin ground state was described by our groups. The accessibility of the low-spin state was hindered by slow dynamics of the high-spin to low-spin phase transition. Here, we report the successful control of this spin-crossover process through metal-ion dilutions. The behavior of thermally induced spin-crossover was observed to emerge or be suppressed depending on the radius of the metal ion used for dilution (Ni-II or Zn-II). The reversible photo-switching was confirmed in all mixed-metal complexes where the low-spin state was thermally accessible.

Summary: High yields of phase-pure K-3[Fe2S4] were obtained using a fast and efficient synthetic technique starting from binary precursors. The compound showed soft ferrimagnetic characteristics due to the mixed valence of Fe-II/Fe-III. Manipulation of microstructure and ratio of grains to grain boundaries through sintering at different temperatures allowed for variation of dielectric and impedance properties. The compound demonstrated potential as a material for electronic and magnetic applications, with high dielectric constant, ionic conductivity, and optical band gap.
