Enhanced electrochemical nitrate reduction to ammonia with nanostructured MoC on carbon nanotube-reduced graphene oxide hybrid support.

The electrochemical nitrate reduction reaction (NORR) is emerging as a promising method for ammonia production under ambient conditions while simultaneously addressing nitrate pollution. Due to the complexity of NORR, which involves multi-electron/proton transfer and competes with the hydrogen evolution reaction (HER), the development of efficient electrocatalysts with high activity and stability is crucial. In this study, we report the use of MoC nanoparticles homogeneously dispersed on a carbon nanotube-reduced graphene oxide hybrid support (MoC/CNT-RGO) as an effective electrocatalyst for NORR.

Exploring the source of ammonia generation in electrochemical nitrogen reduction using niobium nitride.

In this study, niobium nitride (NbN) is prepared the urea-glass route by annealing a mixture of NbCl and urea at 650 °C under a flow of N, 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 mol s cm at -0.

Structural equation modeling of factors associated with nursing students' professionalism during the COVID-19 pandemic.

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.
