For device printing, it is important for uniform films to be printed because the morphology of the film affects the performance of the device in inkjet printing. In this study, to prepare stable and well-dispersed ink, polyacrylate and silicone surfactant BD-3033H were added to ink. Then a uniform quantum dot (QD) film was obtained by optimizing the polyacrylate and silicone surfactant contents of the ink as well as the substrate temperature. The change of the polyacrylate structure from a curly chain structure to a three-dimensional network structure blocked the outward flow of QDs. Silicone surfactant BD-3033H caused Marangoni flow and made the QDs flow inward. When the substrate temperature was increased, the solvent evaporation rate was accelerated, the contact line was pinned, and the outward flow was enhanced, which changed the film structure from convex to flat. Finally, when the polyacrylate content was 12 wt%, the silicone surfactant BD-3033H content was 0.10 wt%, the substrate temperature was 40°C, and the coffee ring effect was eliminated. A uniform QD film was printed, providing a technical guarantee for the fabrication of QD devices in the future.

With the progress of the times, China’s higher education has entered a new era. The combination of innovation and entrepreneurship education with college students’ ideological and political education is an important means for colleges and universities to implement morality, cultivate talents and serve the society. Therefore, while colleges and universities attach importance to entrepreneurship education, it has important practical significance to further strengthen ideological education.Through the analysis of the essential meaning of “curriculum ideological and political”, this article points out the importance of combining ideological and political education with college students’ innovation and entrepreneurship, and analyzes the main problems in the implementation of curriculum ideological and political concepts in college innovation and entrepreneurship education courses.

The dynamic prediction of financial distress can monitor the financial status of an enterprise in real time and provide evidence for financial analysts. However, currently, there are few studies concerning the dynamic prediction of financial distress in the financial sharing environment, so in order to fill this research gap, this study established a dynamic prediction model of financial distress in the financial sharing environment. Firstly, this study employed the analytic hierarchy process (AHP) and entropy weight theory to determine an index system for the dynamic evaluation of financial distress in the financial sharing environment and gave the weight assignment method of the evaluation indexes. Then, based on the probabilistic neural network (PNN), this study constructed a dynamic prediction model of financial distress and used experimental results to verify the effectiveness and feasibility of the constructed model.

Visual teaching is a teaching method or teaching tool that presents a clearer and more intuitive image of music works to students. Drawing on the theory of brainstorming, this paper explores the application of brainstorming, a brain stimulation method, in visual teaching of music. The main results are as follows: visual music teaching mainly improves music skills, cultivates music aesthetics, and enhances communicative competence. Once introduced to music class, the creative thinking method of brainstorming enables the teacher to train the divergent and creative thinking of students. During music teaching, brainstorming stimulates the learning interest, boosts the learning confidence, and cultivates the independent thinking of students. The research findings lay a theoretical basis for music course reform.
