Unraveling the Origin of Unusual Cs Atom Disorder in Cesium Octahedral Molybdenum Halide Cluster Compounds, Cs[{MoX}X] (X = Cl and Br).

In this study, we investigate structural disorder and its implications in metal cluster (MC)-based compounds, specifically focusing on Cs[{MoX}X] (X = Cl and Br). Utilizing synchrotron radiation X-ray diffraction, Fourier transform infrared spectroscopy, and luminescence measurements, we examined the incorporation of water molecules into these compounds and their effects on the crystal structure and optical properties. Our findings reveal that the presence of water molecules induces the lattice disorder, particularly the displacement of Cs atoms.

Associations between prenatal exposure to PFAS and cardiometabolic health in preadolescents.

Introduction: While a number of studies have examined the effects of prenatal exposure to per- and polyfluoroalkyl substances (PFAS) on childhood obesity, the results reported have been inconsistent and few studies have integrated biological markers. The aim of this study was to investigate the associations between prenatal exposure to PFAS and cardiometabolic health parameters at age 12, taking pubertal stage into consideration.

Method: This study included 394 mother-child pairs enrolled in the PELAGIE mother-child cohort (France).

Prenatal exposure to persistent organic pollutants and its impact on the ovarian reserve at 12 years old in the PELAGIE mother-child cohort.

Although the ovarian reserve is constituted in utero, the literature on the effects of persistent organic pollutants (POPs) during this vulnerable period on the ovarian reserve later in life is limited. We investigated whether cord blood concentrations of POPs were associated with decreased anti-Müllerian hormone (AMH, a marker of the ovarian reserve) levels in girls at the age of 12. We included 239 girls from the French mother-child PELAGIE cohort.

Emissive supramolecular ionic crystals combining a red-NIR phosphorescent [ReSeCN] cluster anion and a blue fluorescent tetraphenylethene counter-cation.

A blue fluorescent tetraphenylethylene-based dication and a red-NIR phosphorescent rhenium octahedral cluster tetra-anion are associated electrostatically to generate a supramolecular ionic framework which crystallizes in the 1̄ centric space group. The emission properties of the hybrids are studied in the crystalline state and in solution revealing a resonant energy transfer and a high sensitivity toward oxygen.
