Research Introduction] In response to the new requirements for the use of marine equipment, it is urgent to improve traditional marine engineering materials, design and prepare new antibacterial metal materials with high performance, corrosion resistance and inhibition of bacterial adhesion and growth for the marine environment, and conduct in-depth exploration of their applicability. In response to the above problems, under the guidance of Professor Xu Dake, the project team lasted one and a half years and 1000+ hours of experiments, and finally developed a new antibacterial material with excellent microbial corrosion resistance by adding antibacterial copper elements to high-nitrogen nickel-free stainless steel (HNS) with excellent pitting resistance, and studied its antibacterial and corrosion resistance properties against Pseudomonas aeruginosa. The results showed that the addition of 4wt% copper significantly improved the antimicrobial effect of HNS and the quality of the passivation film, achieving better MIC resistance. The antibacterial rate of HNS-4Cu was 99%, and the depth of the pitting pit was reduced by 425%, electrochemical tests also showed that HNS-4Cu exhibited the best resistance to microbial corrosion (MIC) in the presence of bacteria. The research results were published in the high-level journal Colloid and Interface Science Communications and were selected as the cover. The project research combines active antibacterial and passive pitting resistance to realize the functionalization of structural materials and effectively inhibit microbial corrosion.
【Name of Award】Best Creative Project, My Favorite Project.
【Project Name】Based on the Lei's Pseudo-Squid and Shrimp Cricket Bionic Underwater Robot
【Project members】Wang Jincheng, Bao Mingzheng, Zhou Yang, Chu Yichen, Xia Yifan
【Instructor】Ma Mingxu
Project Introduction] The bionic underwater robot produced by the project includes the main body, the main propulsion mechanism of the fleshy fins on both sides, the propulsion acceleration mechanism of the imitation wrist wing and the center of gravity adjustment mechanism. When swimming underwater, the imitation meat fin propulsion mechanism simulates the meat fin setting of Squid Leys, and when the motor output power is converted into sine wave-like motion, the water is pushed backwards, so as to generate forward thrust and push the body to move slowly and steadily in the ocean. The wrist-like wing propulsion acceleration mechanism simulates the tentacle setting of the squid's tail, and the opening and closing movement is carried out under the drive of the wrist fin driving mechanism, which pushes the water backwards to achieve the purpose of acceleration and rapid swimming underwater. Combined with the center of gravity adjustment mechanism, it can realize underwater floating and diving. Through the cooperation of the three main mechanisms, the bionic robot in this project can move forward with multiple degrees of freedom under water, with high propulsion efficiency, low noise and high flexibility, and can complete the observation task excellently. The project has 2 authorized patents, 1 accepted patent, and 1 has been accepted**. In the China TRIZ Cup College Student Innovation Method Competition, it has achieved the national gold award, the national first prize, and the Internet popularity award grand slam. It has won the first prize in many competitions such as the National College Student Mechanical Innovation Design Competition and the 3D Digital Innovation Design Competition.
【Name of Award】Best Creative Project, My Favorite Project.
【Project Name】Mechanically coupled vector propulsion underwater drone
【Project Members】Zhong Yunan, Li Haoqi, Han Xiao
【Instructor】Sun Shaoni
Project Introduction] The project correlates the multi-degree-of-freedom motion of the hydrofoil through the design of the under-driven bionic flipper, and realizes the movement of the wing through the space mechanism. The bionic turtle robot can reduce the number of drive motors while having the flexibility of turtle movement, thereby reducing the underwater motion noise. A charging coil is added to the abdomen of the tortoiseshell, a sliding track is configured, and a distributed magnetic matrix is set inside the abdomen, which is equipped with a locator and a tracking charging device to wirelessly power the fitting underwater robot. Cooperate with the attitude adjustment mechanism to achieve stable multi-attitude wireless charging function. Due to its biological characteristics, the bionic sea turtle is large in size, and has about 10L of storage space except for the internal control and mechanical mechanism. It can carry a large number of batteries as an underwater relay station to power other underwater robots. The project has 1 authorized patent, 1 accepted patent, 2 have been accepted** and have cooperated with the company to complete the project test. He has won many national and international awards, such as the Good Design Creativity Award (only 9 in the country), the national first prize and the champion of the International Advanced Robot and Technology Competition.
【Name of Award】My favorite project.
【Project Name】New water retention - low-cost preparation process of slow-release calcium fertilizer**
【Project Members】Guo Li, Zhang Youyuan, Li Cui Ruikai, Chao Li, Pu Qinghong
【Instructors】Wang Haiwang, Wei Xinfang
Project Introduction] In view of the serious waste of fertilizer, insufficient fertilizer utilization rate, and soil compaction of cultivated land in China, the research and development team has developed a synergist based on amide-based additives based on the existing cultivated land problems through structural innovation and performance breakthroughs, starting from fertilizer reduction and efficiency increase, which can be applied to plant roots to achieve the effects of water retention, efficiency enhancement and crop yield increase, and has been tested by large-scale field experiments. SiO2-TiO2-PAM additives can effectively fix organic small molecule active substances such as Y-amino acids and polyglutamic acid through physical bonds, which can regulate the release of auxins and other hormones in plants and promote the absorption of fertilizers by plants. SiO2-TiO2-PAM additives quickly absorb and store water and water-soluble fertilizers, so as to realize the enrichment of water and fertilizers near crop roots. At present, the team has obtained 3 core patents and 2 **, all of which are students' works. The research and development team will also continue to devote itself to the research of synergists, help agriculture increase efficiency, and help rural revitalization.

Among them, there are 347 academic articles, 374 reform achievement projects, and 112 entrepreneurship promotion projects. After the preliminary evaluation of experts in relevant disciplines and the re-selection of the expert working group of the "National Innovation Plan", 200 academic articles, 250 reform achievement display projects, and 60 entrepreneurship promotion projects were finally selected, and a total of 510 "National Innovation Plan" project achievements were shortlisted for the finals of the annual meeting.
The finals include three parts: college students' innovation academic exchanges, college students' innovation and entrepreneurship reform achievements project display, and college students' entrepreneurship project promotion, and 20 "excellent academic articles", 21 "my favorite projects", 22 "best creative projects", 12 "best entrepreneurship projects", and 15 "excellent organization awards" were selected respectively. The school attaches great importance to the organization of the annual meeting, identifies the annual meeting as a national six-star competition, and promotes high-quality projects to the previous annual meetings for 16 consecutive years by organizing academic competitions, project achievement exhibitions, annual meeting pre-defense and guidance and other activities. At the finals, the shortlisted project teams actively participated in the exchange and display, competed with high-level projects and first-class contestants, and were widely recognized and praised by teachers, students and experts from various schools.
Those who know how to change win, and those who keep integrity and innovate advance.
Leading the new era, innovation is always strong
Self-improvement, hard work and dedication to innovation
