Improving the safety inspection level of university laboratories is an important guarantee for preventing risks, and protecting the safety of teachers and students’ lives and property. In view of the problems existing in the routine safety inspection of university laboratories, such as lack of full-time safety inspection personnel, insufficient professional ability to identify safety risks. The mechanism construction, qualification certification, work priorities, workflow and cases of the third-party security inspection mechanism are introduced. And The professionalism, fairness and independence of laboratory security inspection are ensured by taking advantage of multiple entities. The new mode of third-party security inspection can improve the safety management level, and safeguard the discipline construction and high-quality talent cultivation.

Elucidating the reaction mechanism of hydrazine oxidation reaction (HzOR) over carbon-based catalysts is highly propitious for the rational design of novel electrocatalysts for HzOR. In present work, isolated first-row transition metal atoms have been coordinated with N atoms on the graphite layers of carbon nanotubes via a M-N₄-C configuration (MSA/CNT, M=Fe, Co and Ni). The HzOR over the three single atom catalysts follows a predominant 4-electron reaction pathway to emit N₂ and a negligible 1-electron pathway to emit trace of NH₃, while their electrocatalytic activity for HzOR is dominated by the absorption energy of N₂H₄ on them. Furthermore, FeSA/CNT reverses the passivation effect on Fe/C and shows superior performance than CoSA/CNT and NiSA/CNT with a recorded high mass activity for HzOR due to the higher electronic charge of Fe over Co and Ni in the M-N₄-C configuration and the lowest absorption energy of N₂H₄ on FeSA/CNT among the three MSA/CNT catalysts.
