How to develop salt lake lithium resources in a green, low-carbon, and efficient manner, and achieve secondary recycling of lithium resources in waste batteries? Professor Chen Fengjuan's team from the School of Chemistry and Chemical Engineering at Lanzhou University has developed a solar driven thin film evaporation technology, which has been successfully used for lithium extraction from salt lakes and low concentration lithium recovery from wastewater. The lithium recovery efficiency has reached over 95%, solving problems for industry enterprises. There are many examples like this at Lanzhou University. In recent years, the school has normalized the promotion of collaborative innovation with industry leading enterprises, accelerating the transformation of scientific and technological achievements. In 2024, Lanzhou University signed 2248 various technology contracts with a total contract amount of 944 million yuan. Behind the numbers, it reflects a series of reform explorations in the field of basic research, management system and evaluation methods reform, and organized transformation by the school. In August 2024, Associate Professor Liu Qiming from the School of Materials and Energy at Lanzhou University joined Longi Green Energy Technology Co., Ltd. to conduct research that is close to the needs of the industry. Leveraging the company's industrial preparation conditions, he attempted to use new processes and materials to prepare samples and improve battery conversion efficiency. As early as December 2021, the school jointly established the Future Technology Research Institute with LONGi, mainly focusing on scientific research and technological development of clean energy technologies, devices, and materials. Thanks to the platform's matchmaking, many teachers like Liu Qiming are deeply involved in enterprise technology research and development, conducting strategic and cutting-edge technology research in fields such as photovoltaic materials and devices. In the field of basic research, Professor Huang Ning's team from the School of Civil Engineering and Mechanics mainly focuses on the motion laws of particulate matter under wind action, and has achieved a series of research results in the field of wind sand (snow, dust) gas-solid two-phase flow. At the end of 2023, the Huang Ning team was commissioned by Three Gorges Group to undertake the project of "Collaborative Gain Technology Research on New Energy Development and Ecological Restoration in the Lower Reaches of Jinsha River". We combine the actual needs of the Jinsha River Basin wind and solar power development base, focusing on key technologies such as improving power generation efficiency, disaster prevention and control, and ecological restoration, hoping to achieve synergistic benefits between new energy development and ecological restoration, "said Huang Ning. After conducting the first domestic meteorological and hydrological multi-element monitoring at different heights in a photovoltaic power station, the team relied on observation data to build a multiphase flow coupled numerical calculation platform under complex terrain, accurately revealing the vertical distribution law of dust around the photovoltaic panels, providing scientific basis for optimizing the layout of photovoltaic arrays, reducing the temperature of photovoltaic panels, and improving power generation efficiency in the future. Our research results are like a 'sharp blade', where they are used is crucial. Our goal is to focus on national strategies and local economic and social development, and tackle key technological issues that urgently need to be solved Huang Ning said. Two personalized customization solutions to solve the difficulties and pain points of enterprises, guiding the on-site transformation of industrialization, and going to Hubei to negotiate cooperation with enterprises on the transformation of scientific and technological achievements... Just after the New Year, Chen Fengjuan was shuttling between schools and enterprises. To truly understand the difficulties and pain points in the production process of enterprises, it is necessary to find the root cause of the problem on site in order to 'prescribe the right medicine'. The feasibility of the processes and technologies we develop can only be determined after the enterprise completes pilot testing and meets all indicators Chen Fengjuan said. Since 2010, Chen Fengjuan has led a team to focus on the research and application of water treatment technology. The team has collaborated with Jinchuan Group Co., Ltd. to use catalytic reduction technology to achieve low-cost and high-efficiency recovery of precious metal platinum from waste liquid. It is widely used in the production of precious metal electroplating products, automotive exhaust catalysts, and pharmaceutical catalysts, with an economic benefit of over 10 million yuan. In recent years, with the rapid development of the new energy industry, the development and recycling of lithium resources in salt lakes have received widespread attention. How to develop salt lake lithium resources in a green, low-carbon, and efficient manner, and efficiently and cost effectively recover the brine generated during the production process of lithium products? This is a key issue facing the lithium extraction and lithium product production industry in salt lakes. The solar driven thin film evaporation technology developed by Chen Fengjuan's team is perfectly compatible with the enterprise, and the two parties quickly reached a cooperation agreement. We have been providing customized water treatment solutions to our customers in order to better achieve the transformation and implementation of scientific and technological achievements and serve enterprises, "said Chen Fengjuan. The team's scientific research achievements are also widely used in enterprises such as China Rare Earth Group, Zhongjin Lingnan, and Northern Rare Earth. In 2024, Professor Yao Ze'en's team from the School of Nuclear Science and Technology will complete the transformation of scientific and technological achievements by investing in the first domestically developed compact D-D neutron generator through pricing. They will cooperate with China Shaanxi Nuclear Industry Group Co., Ltd. to jointly establish China Shaanxi Nuclear (Xi'an) Neutron Technology Co., Ltd. Neutron technology has achieved a magnificent transformation from the laboratory to the industry market. Compact neutron generators are important controllable neutron sources with broad application prospects in real-time online neutron activation analysis, fast neutron photography, and other fields. Yao Zeen said that currently, the mainstream neutron source used for neutron activation analysis in industrial sites is the Californium-252 spontaneous fission neutron source. But the neutron source of this isotope is monopolized by foreign countries, with extremely low production and high prices, and a half-life of only 2.6 years. The development of accelerator neutron sources has always been a traditional advantage of the nuclear discipline at Lanzhou University. With the support of the National Key R&D Program, Yao Zeen's team developed the first compact D-D neutron generator in China in 2020, with a neutron production rate of 2.0 * 108n/s. In recent years, the team has customized 4 sets of equipment for relevant research institutions in the form of technology development and technical services. In the process of converting laboratory equipment into products, continuous technological iterations should be carried out according to the different performance requirements of different users Professor Wei Zheng, a member of the team, introduced that the compact neutron generator has undergone technological iteration to the second generation and is working hard to develop a new generation, striving to reach the international advanced level. In January of this year, Lanzhou University revised the "Management Measures for the Transformation of Scientific and Technological Achievements at Lanzhou University", increasing the distribution ratio of research personnel's transformation benefits from 70% to 90%. The favorable policies of the school have made Yao Zeen very pleased: "This will further motivate researchers to accelerate the transformation of scientific and technological achievements
