Latest ArticlesObjective To compare the different extraction methods of soybean crude fatty acid value with the national standard method GB 5009.229-2016 National Standard forFood Safety-Determination of Acid Value in Food. Methods The room temperature extraction method, organic solvent oscillation method, and ultrasonic assisted method were used to detect the crude fatty acid value of soybeans, and compared with the Soxhlet extraction method required by the national standard method. Results The crude fatty acid value of soybeans measured by 3 kinds of extraction methods is basically consistent with the national standard method, and the extraction speed is significantly faster than the Soxhlet extraction method in the national standard. Among them, the ultrasonic assisted extraction method has the shortest extraction time, only requiring 20 minutes; as the sample size increases, the extraction efficiency of the room temperature extraction method improves more significantly. Conclusion Daily testing of grain and oil enterprises can shorten time, reduce costs, and improve efficiency by selecting suitable extraction methods based on sample batch size.

Production safety is related to people's well-being and the overall situation of economic and social development. However, laboratory hazardous chemical safety-related incidents have occurred in recent years, which has sounded the alarm for laboratory safety management in colleges and universities. This paper focuses on the outstanding problems and weak links in the safety management of university laboratories and hazardous chemicals, and focuses on the work carried out by the university in the implementation of responsibilities, system construction, publicity and education, hazard source control, hidden danger investigation and rectification, emergency drill and information platform construction, so as to provide reference for the fine management of hazardous chemicals in university laboratories.
Under the new circumstances of rapid social and economic development in China, higher education is experiencing significant growth. The government is increasingly emphasizing the importance of laboratory safety in science and engineering universities. Given the significant roles of university laboratories in teaching and research, laboratory safety is characterized by diversification, complexity, and specialization. This paper analyzes the main challenges faced by safety management in engineering university laboratories and proposes improvement measures from four perspectives: strengthening and refining the laboratory safety management responsibility system, timely revision of safety-related documents, promoting safety awareness and education, intensifying laboratory safety inspections, establishing a laboratory safety management information system. These measures aim to enhance the overall level of laboratory safety management, providing solid support for the safe operation of laboratories and facilitating teaching and research activities.
Taking Jiangnan University as the practice subject, the paper studies the interdependence of the preparation, procurement, use and disposal stages in the full life cycle management system of large scientifiic research instruments and equipment.Taking this as the cornerstone, in view of the main problems existing in the equipment management. The improving measures are proposed including promoting information construction, making good budget demonstration, improving the performance appraisal, widening the channel of disposal, strengthening the team construction. The present study aimed at by means of actively exploring the fine full life cycle management of large scientifiic research instruments and equipment, improving management level of instruments and equipment in colleges and universities in the new era to better service for teaching and scientific research.
Aiming at the common problems existing in the scientific research laboratories of universities, such as the low level of information management, the unclear responsibility of laboratory management, the lack of equipment maintenance in the later stage and the low utilization ratio of instruments and equipment, this study proposes a"Flexible" laboratory management mechanism to solve the bottleneck problem of laboratory management. “Flexible management" is to optimize all kinds of existing soft and hard resources into a "Flexible" whole by establishing an information-based management platform, the invention solves the problems of low utilization rate of laboratory and instrument equipment, repeated purchase of the same kind of equipment, and difficulty in late-stage maintenance of equipment. Therefore, it is an inexorable trend of engineering laboratory construction to construct an efficient and extensible flexible mechanism.
In view of the current situation of laboratory management in local colleges and universities, in order to realize the reform of informatization of laboratory management system in local colleges and universities, it is proposed to build a lightweight laboratory information sharing platform. This paper analyzes the operation characteristics and existing problems of laboratories in local colleges and universities, and discusses the application value of information technology in laboratory management. On this basis, a low-cost and lightweight information sharing platform is constructed. Combined with the current difficulties of laboratory management in institutions, the platform is divided into four basic modules of instruments and equipment, reagents and consumables, users and information push for construction, in order to enhance the transparency and sharing efficiency of laboratory information and improve the laboratory management mode in local institutions.
As important bases for experimental teaching and medical research, the biosecurity of laboratories in medical universities cannot be ignored. In order to accurately grasp the research progress of biosecurity management in medical university laboratories in China, co-word cluster analysis was conducted on the 473 literatures related to biosecurity in medical laboratories published in the CNKI database from 2004 to 2023 using CiteSpace software. The research results showed that biosecurity, laboratory safety management, safety education, and medical testing are the four current research hotspots in this field, while medical research laboratories and safety education are potential directions for future research development.
For the experimental research of Xinjiang oilfield, all kinds of research work can not be separated from experiments. As an important place of scientific and technological research and development, the quality and level of scientific and technological research and development are directly affected by the management of the laboratory, therefore, it is of great significance to do a good job in the management of the laboratory. According to the actual situation of laboratory work, this paper summarizes the experience of laboratory management, and puts forward and implements the innovation mechanism of safety autonomous management in the course of experimental research from the aspects of creating safety concept culture and establishing standardized management mode, etc., the purpose of this paper is to promote the high-quality and high-efficiency of scientific research and production by improving the management of laboratories in oil-field scientific research units, it provides guarantee for Xinjiang oilfield to create greater economic benefits.
Against the backdrop of increasingly collaborative global scientific research, regional joint laboratories have gradually gained attention as important platforms for improving research efficiency and transforming achievements. As an effective platform for integrating regional research resources and promoting deep integration of industry, academia, and research, research consortia can play a key role in enhancing regional innovation capabilities of regional joint laboratories and accelerating the transformation of scientific and technological achievements. This article aims to explore the construction and open sharing strategy of regional joint laboratories based on research consortia, analyze the challenges and opportunities faced in the current construction and operation of regional joint laboratories, and propose corresponding countermeasures and suggestions.
