ABSTRACT
This study aimed to determine the factors associated with nursing professionalism among Korean nursing students. This cross-sectional study was carried out using a convenient sample comprising 247 students enrolled in a four-year Bachelor of Science Nursing program from September 6-27, 2021. A self-reported structured questionnaire was employed to explore the relationships among ego-resilience, self-leadership, clinical learning environment, academic satisfaction, clinical competency, and nursing professionalism by utilizing structural equation modeling. The modified model exhibited good fit indices. Learning-related factors, including clinical learning environments, academic satisfaction, and clinical competency, directly affected nursing professionalism. Self-leadership and the clinical learning environment were indirectly associated with nursing professionalism via both academic satisfaction and clinical competency. Regarding ego-resilience, it only indirectly affected nursing professionalism via academic satisfaction. Creating a student-centered learning environment may be vital to improve students' major and clinical performance, thereby boosting nursing professionalism. Furthermore, nurse educators should consider individual psychological aspects of students when designing the nursing curriculum to foster nursing professionalism. Longitudinal studies are needed to determine if our model is available to explain the development of professionalism among nursing students.
ABSTRACT
In this study, niobium nitride (NbN) is prepared via the urea-glass route by annealing a mixture of NbCl5 and urea at 650 °C under a flow of N2, and is used as a catalyst for the electrochemical nitrogen reduction reaction (NRR). The as-prepared NbN exhibits a maximum production rate of 5.46 × 10-10 mol s-1 cm-2 at -0.6 V vs. RHE, along with an apparent FE of 16.33% at -0.3 V vs. RHE. In addition, the leaching of NbN is confirmed by ICP-OES, where the leached amount of Nb is almost identical to the amount of N measured by UV-vis. Moreover, 1H NMR experiments are performed using 15N2 as the feeder gas; the dominant detection of 14NH4+ peaks strongly suggests that the produced NH3 originates from the leaching of NbN rather than via an electrocatalytic process. Hence, for a comprehensive understanding of NH3 generation, especially when utilizing transition metal nitride (TMN)-based NRR catalysts, a thorough investigation employing multiple analytical methods is imperative.
