Abstract： [Objective]To explore the model construction and specific practical strategies for the collaborative efforts between science and technology journals and knowledge opinion leaders in popular science communication.[Methods]Using literature analysis and case study methods to dissect how science and technology journals and opinion leaders can effectively collaborate in popular science communication activities,revealing the key components and operational mechanisms of their cooperation model.[Results]The collaboration between science and technology journals and opinion leaders in popular science communication can achieve complementary advantages and mutual benefits. From a systems theory perspective,a cooperative popular science communication model is constructed, encompassing an implementation system,a quality assurance and evaluation system, and an incentive system.[Conclusion]Science and technology journals should actively integrate internal and external resources, establish and improve cooperation mechanisms, jointly innovate forms of popular science, expand communication channels, and enhance the social value of scientific research outcomes.

Abstract： Purposes To explore new pathways and insights for knowledge services in Chinese STM journals in the era of large language model technology by analyzing the operational model and technical implementation of the novel knowledge service platform, Consensus.app. Methods By combining literature review and online empirical research, this study analyzed the functions, features, and manifestations of knowledge services provided by the Consensus.app platform. In this paper, the technical implementation methods employed by the platform and its role in promoting knowledge acquisition from scientific literature were investigated, while its potential advantages and disadvantages were summarized too. Results The corpus of the Consensus.app platform was built by collecting abstract information from the Semantic Scholar paper database, and it employs various artificial intelligence technologies, including natural language processing, machine learning, and information retrieval. By extracting key information from research papers and creating a vectorized knowledge database, Consensus.app utilizes OpenAI’s interface to retrieve relevant information from the knowledge base based on user queries and provides summarized conclusions as feedback to users. The platform offers highly personalized interactions, directly providing data-supported conclusions for different queries and enabling quick access to snapshot information of relevant literature, assisting users in making rapid decisions. Conclusions The emergence of Consensus.app partially addresses the issues of accuracy and evidence chain that are lacking in large-scale language model responses. It also provides more diverse scenarios for the widespread and efficient application of scientific journals in the era of large-scale language models. It demonstrates a new pathway for integrating large language models to construct knowledge repositories and provide knowledge services for STM journals. In the new era, the STM journal community needs to attach great importance to data quality construction, cross-disciplinary collaboration, copyright improvements, actively join large-scale databases, embrace the trend of the era of large models, and embrace the AI+ era of STM journals.

Abstract： The influence of simultaneous addition of 1.0La, 0.7Ce and 3.0Sm (mass fraction, %) on corrosion behavior of AZ91D alloy was studied by means of corrosion loss test and polarization curve as well as XRD, SEM with EDS etc, and then the corrosion mechanism was also interpreted. The results show that the addition of La, Ce and Sm can refine the alloy. After the addition of La, Ce and Sm, the AZ91D alloy exhibited higher free- corrosion potential, lower free- corrosion current, bigger Tafel slope and higher corrosion resistance performance, but which is slightly lower than the alloy with the addition of single rare earth Sm.

Abstract： The influence of 0.1%, 0.4%, 0.7% and 1.0% Sm addition on microstructure and corrosion property of AZ91D alloy was studied by means of SEM with EDS, XRD, corrosion weight loss test and electrochemical polarization curve etc. The results show that with the increasing Sm content, the bulky dendritic second phase (β-Mg17Al12) in the alloy becomes finer and the volume fraction of which decreases gradually, whilst Sm may combine with Al to form granular Al2Sm and rod-shaped Al3Sm, thereby, cutting down the number of the second phase in grain boundaries, leading to the second phase discontinuous distribute; Sm can improve the corrosion resistance of alloy, but the corrosion resistance firstly increases and later decreases with the increasing Sm content. The corrosion resistance of the alloy with 1.0% Sm is close to the bare AZ91D. The optimum addition amount is 0.4% Sm for the highest corrosion resistance.
