Combining artificial intelligence (AI) technology, the physics teaching team of Xi’an Jiaotong University and Chaoxing Company jointly built two smart courses, “University Physics Quantum Physics” and “University Physics Thermodynamics”, on the Fanya platform. The course features an intelligent curriculum-map system that is underpinned by a knowledge graph, driven by a problem graph, guided by an objective graph, and implicitly shaped by ideological and political education graph. It creates a virtual learning environment together with an intelligent tutoring and Q&A system, incorporates intelligent assessment and monitoring capabilities within the smart course, and provides an AI teaching assistant. This paper presents the AI-based methodology and principal measures adopted to build a smart university physics course, along with the initial outcomes already achieved. Leveraging this smart course initiative, the teaching team has attained outstanding results in textbook development, exemplary cases of ideological and political education, and the publication of pedagogical reform papers.

The construction of the new engineering disciplines and the “Strengthening Basic Disciplines Plan” are significant strategic initiatives successively deployed by the Ministry of Education at the national level to cultivate future talents in new technologies and outstanding talents in basic disciplines. As one of the first batch of “Strengthening Basic Disciplines Plan” majors identified by the Ministry of Education, physics, being the cornerstone of natural sciences, will also be the original driving force and virgin land for the development of new engineering disciplines. Can we effectively connect the construction of new engineering disciplines with the “Strengthening Basic Disciplines Plan” in physics majors, build a platform for the integration and shared construction of science and engineering, create an integrated cultivation mechanism for undergraduate, master's, and doctoral programs in science and engineering, and achieve a talent cultivation model that transitions from science to the integration of science and engineering? This article introduces the implementation plan, reform measures, and preliminary achievements of cultivating new engineering talents based on the “Strengthening Basic Disciplines Plan” in physics majors at comprehensive universities with engineering advantages. It reports on the exploration and practice of Xi'an Jiaotong University in carrying out reform of the talent cultivation model and mechanism in new engineering disciplines based on the physical discipline, hoping to provide references and insights for other universities with engineering advantages to cultivate new engineering talents in their physics disciplines.

As a common thing in life, the storage method of chocolate has always been an important subject of research in food science. The phenomenon of chocolate solidification and melting caused by phase change has a decisive impact on the storage of chocolate; However, due to the complex composition and variable crystal structure of chocolate, it is currently only achieved in daily life to control the storage of chocolate to maintain good properties, and there is little research to analyze the phase transition mechanism behind it. Firstly, based on the Landau de Vonseia theory, the relevant factors affecting phase transition were described using order parameters, and the hysteresis phenomenon in chocolate phase transition was preliminarily explained; Subsequently, relevant experiments were conducted and a modification to Landau's theory was proposed to explain the experimental phenomenon; Finally, by studying the ferroelectric phase transition of cocoa butter crystal, the main component of chocolate, the generation of potential barrier that has not been explained in De Vonseyer's theory is expounded.
