Recently, the international applied technology innovation competition was concluded in weihai, shandong province. Xu guangqiao, a second-year graduate student of our university, won the first prize for his entries, which were selected from more than 400 domestic and 300 foreign entries. The winning projects "a leak of crude oil by using porous graphene based materials, rapid, large-scale management recycling systemic solution" is the result of major projects of national natural science fund, using the two features of load graphene sponge (high light of absorption, oil-wet hydrophobic), which can realize the most difficult to handle solid crude oil recycling. The research team proposed a systematic solution for the treatment and protection of low-viscosity crude oil, high-viscosity crude oil and beach oil pollution, which is expected to be applied in practice.

The international applied technology innovation competition, the contestants include graduate students, undergraduates and the company''''s technical research and development personnel. Under the hard guidance of yu wei and zhang li, the postgraduate students in our school have been recognized by experts in such fierce competition for more than a year, which shows the remarkable effect of postgraduate training in our school and also encourages the majority of students to forge ahead with courage and perseverance in scientific research.
