Aims and objectives: To investigate the prevalence and extent of burnout on nurses and its association with personal resilience.Background: With the worldwide shortage of nurses, nurse burnout is considered

A nanocomposite Ni/CeO 2 −CDC-SiC catalyst which consists of highly dispersed Ni nanoparticles contacting intimately with CeO 2 nanoparticles on a nanoporous carbide-derived carbon (CDC) layer over SiC support has been successfully designed for carbon dioxide (CO 2 ) reforming of methane. In comparison with the Ni/CDC-SiC catalyst, the ceria-promoted Ni/ CDC-SiC catalyst possessed enhanced activity and improved stability. The catalysts were systematically characterized with N 2 sorption, X-ray diffraction, transmission electron microscopy, energy-dispersive X-ray spectrometry elemental mapping, thermogravimetric/differential thermal analysis, temperature-programmed reduction, and X-ray photoelectron spectroscopy measurements. It was found that, after introducing CeO 2 promoter, the specific surface area was increased, and a smaller Ni particle size was obtained. The smaller Ni particle size led to an enhanced reforming activity. The presence of abundant Ni− CeO 2 interfaces on the CeO 2 -promoted catalyst accelerated the carbon removal through the lattice oxygen species, which resulted in superior carbon resistance and thus an improved stability. The outcome of the present work is expected to shed meaningful insight into the design of nanocomposite catalysts with the aid of metal−oxide interfaces.

Uniform Au nanoparticles (∼2 nm) with narrow size-distribution (standard deviation: 0.5-0.6 nm) supported on both hydroxylated (Fe_OH) and dehydrated iron oxide (Fe_O) have been prepared by either deposition-precipitation (DP) or colloidal-deposition (CD) methods. Different structural and textural characterizations were applied to the dried, calcined and used gold-iron oxide samples. Transmission electron microscopy (TEM) and high-resolution TEM (HRTEM) showed high homogeneity in the supported Au nanoparticles. The ex situ and in situ X-ray absorption fine structure (XAFS) characterization monitored the electronic and short-range local structure of active gold species. The synchrotron-based in situ X-ray diffraction (XRD), together with the corresponding temperature-programmed reduction by hydrogen (H2-TPR), indicated a structural evolution of the iron-oxide supports, correlating to their reducibility. An inverse order of catalytic activity between DP (Au/Fe_OH < Au/Fe_O) and CD (Au/Fe_OH > Au/Fe_O) was observed. Effective gold-support interaction results in a high activity for gold nanoparticles, locally generated by the sintering of dispersed Au atoms on the oxide support in the DP synthesis, while a hydroxylated surface favors the reactivity of externally introduced Au nanoparticles on Fe_OH support for the CD approach. This work reveals why differences in the synthetic protocol translate to differences in the catalytic performance of Au/FeOx catalysts with very similar structural characteristics in CO oxidation.

Aim To evaluate the effects of a WeChat‐based “Three Good Things” on job performance and self‐efficacy of clinical nurses with burnout symptoms. Background Few studies have valued the impact of nurses' personal strengths and positive work environment on job performance, particularly in developing countries. Methods A randomized controlled trial. The intervention group (n = 33) participated in WeChat‐based Three Good Things, while the control group (n = 40) did not. Data were collected prior to and immediately after the intervention. WeChat, a popular social software, provides several communicating and recording functions. Results The main intervention effects and interactions between time and intervention on job performance and self‐efficacy were significant (each p < .05). The main time effects on self‐efficacy were also significant (p < .05). The post‐intervention scores for job performance and self‐efficacy between the two groups were statistically different (each p < .05). The scores for job performance and self‐efficacy of the intervention group were statistically different before and after the intervention (each p < .05). Conclusion Three Good Things could significantly improve job performance and self‐efficacy of nurses with burnout. Implications for Nursing Management Nurse managers are recommended to include Three Good Things into their management systems to improve nurses' physical and mental health and work outcomes over the long term.

A novel Ni/Mg–Al–O catalyst has been successfully synthesized by the cation–anion double hydrolysis (CADH) method for carbon dioxide (CO2) reforming of methane. Compared with the Ni/MgO–Al2O3 catalyst prepared by the conventional co-impregnation method, the Ni/Mg–Al–O catalyst exhibited enhanced initial activity and improved long-term stability. Structural characterizations revealed that higher metal dispersion (2.8 times) and better intrinsic activity (1.8 times in terms of turnover frequency at 700 °C) were achieved by ultrasmall Ni nanoparticles (2.1 nm) on the Ni/Mg–Al–O catalyst, leading to the enhanced initial activity. The improved long-term stability of the Ni/Mg–Al–O catalyst was attributed to the superior anti-coke property, which was rationalized by the ultrasmall Ni nanoparticles and abundant basic sites. The present work provides a facile and green method for the synthesis of efficient reforming catalysts and elucidates the mechanisms underlying excellent catalytic performances.
