Using molybdenum carbiding to induce digestion of carbon in HO: A sustainable approach to eliminate radioactivity for hazardous graphite waste inherited from nuclear enterprise.

To properly manage nuclear wastes is critical to sustainable utilization of nuclear power and environment health. Here, we show an innovative carbiding strategy for sustainable management of radioactive graphite through digestion of carbon in HO. The combined action of intermolecular oxidation of graphite by MoO and molybdenum carbiding demonstrates success in gasifying graphite and sequestrating uranium for a simulated uranium-contaminated graphite waste.

Tailoring the triplet level of isomorphic Eu/Tb mixed MOFs for sensitive temperature sensing.

Three different thermo-responsive fluorescent thermometers were constructed by regulating the triplet energy level of organic ligands in isostructural Eu/Tb mixed MOFs. Among them, a quite unusual and rarely reported temperature-dependent fluorescence behavior was observed in LnBDC-NH, and EuTbNDC is effective in the physiological range with the maximum relative sensitivity of 7.32% °C.
