Construction of a Virtual Simulation Practice Teaching System of the Chemical Industry Under the Background of Integration of Production and Education

With the development of the integration of production and education,chemical engineering and technology education is facing many new challenges and opportunities.The construction of a chemical virtual simulation practice teaching system under the background of integration of production and education aims to improve students’learning efficiency and innovation ability with the help of virtual simulation technology,so as to meet the needs of future industrial development.This paper discusses the significance of the construction of the system,analyzes the difficulties and challenges that may be encountered in the construction process,and evaluates the effective strategies to strengthen the construction of the system.Through the introduction of virtual simulation technology,students can improve their practical skills and innovation ability,and better adapt to the development needs of industrialization and informatization.

Theory Critique of Kristen Swanson’s Theory of Caring

Theory is considered essential for integral assessment, adopting its foundations and concepts is of great utility. The theory provides different templates to help nurses provide care that respects patients and improves outcomes. Through understanding the intersection of nursing, patients, health, and the environment, theories aim to simplify the complicated, ever-evolving relationship that nurses have with their profession. Nursing theory helps distinguish nursing as a separate discipline from medicine and related sciences, and assists nurses in understanding their patients and their needs. The behaviors of healthcare providers affect how patients participate in and experience care situations. In the nursing discipline, the theoretical structures of caring have been established as the core concept of guidance in all nurses’ work. The aim of this paper is to develop a critique of Kristen Swanson’s theory of caring—a theory structured around five caring principles (maintaining belief, knowing, being with, doing for, and enabling) by applying it to nursing practice. When applied to nursing practice, each of these five stages stimulates the caregiver’s attitude, which in turn improves the overall patient’s well-being. Implications to nursing practice are mentioned [1] [2].

Polyethylene imine functionalized porous carbon framework for selective nitrogen dioxide sensing with smartphone communication

Highly selective and remotely communicable nitrogen dioxide(NO_(2))sensing may contribute to future Internet of Things in environmental monitoring.However,room-temperature NO_(2)sensing materials such as carbon materials is still less than satisfactory due to their insensitive interaction with target gas.Here,polyethylene imine functionalized three-dimensional(3D)carbon framework(PEI/C framework)has been developed for enhanced selective NO_(2)sensing,via combined template synthesis and subsequent doping.Typically,the 3D PEI/C framework is observed porous shape with irregular coating.Beneficially,the response of C framework to NO_(2)increases while those of interfering gases decrease after being functionalized with PEI.Remarkably,the sensor prototypes show a 100 ppb-concentration detection limit at room temperature.Theoretically,such excellent NO_(2)sensing is attributed to the large specific surface ratio of porous 3D PEI/C framework,in which PEI serves as an active layer for target NO_(2),while a passivated one for interfering gases.Practically,such PEI/C framework sensor prototype is simulated for NO_(2)sensing device and communicated with a smartphone,showing great potential in future intelligent environmental monitoring.
