Our University Won the Second Prize of the 6th Safety Science and Technology Progress Award of the China Association of Work Safety

On December 23, the list of winners of the 6th Safety Science and Technology Award of the China Association of Work Safety was announced. The project Precise Sealing Technology of Glass Crucibles for Differential Scanning Calorimetry and Its Application in the Measurement of High-Energy Chemicals, led by Professor Sheng Min, Director of the Key Laboratory of the Shanghai Emergency Management Bureau (Chemical Reaction Safety) of our School of Resources and Environmental Engineering, won the second prize of the Science and Technology Progress Award under the Safety Science and Technology Award.

At present, safety risk assessment technologies related to the explosion reaction of high-energy chemicals are relatively scarce. The calorimetry method promoted in GB/T 42300-2022 Specification for Safety Risk Assessment of Fine Chemical Reactions has been widely used in the field of reaction safety risk assessment of chemicals. However, in view of the high energy density and fast reaction rate of high-energy chemicals during the decomposition reaction, the test data of most calorimetry methods have relatively large errors, especially the real decomposition heat of high-energy chemicals cannot be accurately measured, which leads to the neglect of the explosion hazard of high-energy chemicals in the production process. 

This project aims to solve the current problem that it is difficult to accurately measure the decomposition heat of high-energy chemicals using calorimetry methods. The team has developed a precise sample sealing technology for glass crucibles based on the differential scanning calorimetry (DSC) test method, which realizes the accurate determination of the characteristic parameters of decomposition heat of milligram-level high-energy chemicals, and is at the leading level in the world. This glass capillary crucible can replace metal crucibles and solve the problem of inaccurate test results for high-energy chemicals. In addition, the use of glass capillary crucibles addresses problems such as poor chemical compatibility, high leakage risk, low pressure bearing capacity, excessive headspace volume, easy vaporization of solvents, easy oxidation of samples, and unstable baseline associated with metal crucibles, and reduces the consumable cost of DSC crucibles (to 1% of the original consumable cost). The international standard ASTM E537-24 and the China Chemical Industry Association standard T/CCSAS 055-2025, which were led and revised by Professor Sheng Min and have been issued and implemented, both recommend this test method, and this technology is in an internationally leading position in terms of innovation, practicality and application scope. 

This is the first time that our Reaction Safety Research Center has won a science and technology award, which lays a solid foundation for further serving the national strategy and improving China's safety science and technology level in the future.
