An Icosahedral 55-Atom Iron Hydride Cluster Protected by Tri--butylphosphines.

Nanoclusters are nanometer-sized molecular compounds characterized by significant metal-metal bonding and low average oxidation states, and they exhibit unique properties distinct from those of small metal complexes or nanoparticles. Unlike noble metals stable in metallic forms, the synthesis of nanometer-sized iron clusters has been precluded by the relatively weak iron-iron bonds and the high reactivity of low oxidation state iron, despite the extensive history of molecular iron compounds. Here, we report the synthesis and characterization of a cationic 55-atom iron cluster with a 1.

Factors involved in maintaining Karnofsky Performance Status (≥ 50%) in glioblastoma, IDH-wildtype patients treated with temozolomide and radiotherapy.

Karnofsky Performance Status (KPS) is a widely used scale to assess performance status. KPS ≥ 50% implies that patients can live at home. Therefore, maintaining KPS ≥ 50% is important to improve the quality of life of patients with glioblastoma, whose median survival is less than 2 years.

Unveiling the Antithermal Quenching Behavior in 0D Inorganic Metal Halide CsInCl(HO) Mediated by Upconversion Emission.

Inorganic metal halides (IMHs) often suffer from severe fluorescence thermal quenching, limiting their application at elevated temperatures. Therefore, the exploration of IMHs exhibiting antithermal quenching (ATQ) behavior is of great importance. In this study, we developed a green synthetic route using a solvent evaporation method to successfully synthesize the 0D IMHs CsInCl(HO).

Internal Electric Field Manipulates Exciton-Phonon Couplings in Single Lead Halide Perovskite Nanocrystals.

Lead halide perovskite nanocrystals (NCs) have attracted much attention as materials for light-emitting diodes and quantum light sources. A deep understanding of exciton-phonon couplings is essential for obtaining a narrow emission line, weak phonon-sideband photoluminescence (PL), and a long exciton coherence time, which are especially useful for high-color-purity quantum-light-source applications. Here, we report the PL spectra of single CsPbBr NCs at 5.

Quantitative analysis of air-oxidation reactions of thiolate-protected gold nanoclusters.

The interaction of dioxygen (O) with inorganic nanomaterials is one of the most essential steps to understanding the reaction mechanism of O-related reactions. However, quantitative analyses for O-binding processes and subsequent oxidation reactions on the surface are still elusive, whereas the reaction of O with molecules such as transition metal complexes has been widely explored. Herein, we have quantitatively evaluated reaction processes of air-oxidation reactions of atomically precise thiolate-protected Au nanoclusters ([Au(SR)]) as a model of O activation by inorganic nanomaterials.
