Adsorption and Detection of Iodine Species by a Thorium-Based Metal-Organic Framework.

Actinide-bearing metal-organic frameworks (MOFs) encompass intriguing structures and properties, but the radioactivity of actinide cripples their applications. Herein, we have constructed a new thorium-based MOF () as a bifunctional platform for the adsorption and detection of radioiodine, a more radioactive fission product that can readily spread through the atmosphere in its molecular form or via solution as anionic species. The iodine capture within the framework of from both the vapor phase and the cyclohexane solution has been verified, showing that features maximum adsorption capacities () of 959 and 1046 mg/g, respectively.

Reduced plasma coagulation factor XIII in patients with acute leukemia in remission during consolidation chemotherapy cycles.

Acute leukemia (AL) is a malignancy from hematologic stem cells (HSC). Consolidation with intensive chemotherapy is required after induced remission and repeatedly causes treatment-related bleeding that is usually attributed to chemotherapy-induced thrombocytopenia (CIT). However, our previous study demonstrated that severe deficiency of plasma coagulation factor XIII (pFXIII) also participated in the bleeding of CIT in AL.

Autophagy induction promoted by mA reader YTHDF3 through translation upregulation of FOXO3 mRNA.

Autophagy is crucial for maintaining cellular energy homeostasis and for cells to adapt to nutrient deficiency, and nutrient sensors regulating autophagy have been reported previously. However, the role of eiptranscriptomic modifications such as mA in the regulation of starvation-induced autophagy is unclear. Here, we show that the mA reader YTHDF3 is essential for autophagy induction.

A MOF-based luminometric sensor for ultra-sensitive and highly selective detection of chromium oxyanions.

Sensitization of Cr(VI) oxyanions in environmentally or industrially relevant aquatic media is highly desired owning to their biological toxicity and essential role in nuclear fuel cycle. However, many chemosensors of CrO and CrO suffer from critical drawbacks, including insufficient sensitivity, selectivity, and/or hydrolytic stability. In this work, we prepared a hydrolytically stable metal-organic framework, namely Hf-BITD, which can retain its crystallinity and structural integrity in solutions over a wide pH range (0-12) and in 3 M HCl.

A Water-Soluble Highly Oxidizing Cobalt Molecular Catalyst Designed for Bioinspired Water Oxidation.

Herein, we present a stable water-soluble cobalt complex supported by a dianionic 2,2'-([2,2'-bipyridine]-6,6'-diyl)bis(propan-2-ol) ligand scaffold, which is a rare example of a high-oxidation species, as demonstrated by structural, spectroscopic and theoretical data. Electron paramagnetic resonance (EPR) spectroscopy and magnetic susceptibility measurements revealed that the Co center of the mononuclear complex in the solid state resides in the high spin state (sextet, S=5/2). The complex can effectively catalyze water oxidation via a single-site water nucleophilic attack pathway with an overpotential of only 360 mV in a phosphate buffer with a pH of 6.

Unveiling the Unique Roles of Metal Coordination and Modulator in the Polymorphism Control of Metal-Organic Frameworks.

Polymorphism control of metal-organic frameworks is highly desired for elucidating structure-property relationships, but remains an empirical process and is usually done in a trial-and-error approach. We adopted the rarely used actinide cation Th and a ditopic linker to construct a series of thorium-organic frameworks (TOFs) with a range of polymorphs. The extraordinary coordination versatility of Th cations and clusters, coupled with synthetic modulation, gives five distinct phases, wherein the highest degree of interpenetration (threefold) and porosity (75.
