Aim: To identify subtypes of job crafting among Chinese nurses and to explore the characteristics of different subtypes and their relationship with work engagement. Design: A cross‐sectional study. Methods: A survey of 350 clinical nurses was conducted between December 2022 and January 2023. Identify profile categories for nurses' job crafting using a latent profile analysis. Logistic regression and ANOVA were used to explore the characteristics of different categories of nurses' job crafting in terms of sociodemographic, work engagement variables. Results: Ultimately 3 latent profiles are identified: low job crafting (Class 1, N = 177, 50.7%), moderate job crafting (Class 2, N = 136, 38.9%), high job crafting (Class 3, N = 37, 10.5%). Nurses who are female, aged 31 to 40 and married are more likely to be grouped into Class 2. Nurses with a middle level of title are more likely to be grouped as Class 3. Nurses with high levels of work engagement are more likely to be grouped as Class 2 and Class 3 rather than Class 1. Conclusion: The job crafting has a distinctly classified character among Chinese nurses. 89.6% of nurses were at a low to medium level of job crafting, work engagement is an important predictor of nurses' job crafting. Nursing Managers should focus on the low job crafting group and develop targeted interventions to help nurses improve their job crafting and work engagement levels.

By using density functional theory calculations combined with the nonequilibrium Green's function method and machine learning, we systematically studied the thermoelectric properties of four kinds of porous graphene nanosheets (PGNS) before and after nitrogen doping. The results show that the thermoelectric performance of porous graphene nanosheets along the armchair or zigzag chiral direction is improved due to the dramatically enhanced power factor caused by nitrogen doping. The calculated ZT values of nitrogen-doped porous graphene nanosheets are boosted by about one order of magnitude compared with those of undoped porous graphene nanosheets at room temperature. More importantly, an anisotropic thermoelectric transport is found in the nitrogen-doped porous graphene nanosheets. The results show that the ZT values of nitrogen-doped porous graphene nanosheets along the zigzag transport direction are nearly 11 times larger than those of them along the armchair transport direction. These results reveal that the thermoelectric properties of porous graphene nanosheets can be well regulated by nitrogen doping, and provide a good theoretical guidance for their application in thermoelectric devices.

Assembling anisotropic structures with versatility such as good thermal conductivity and mechanical loading for radiation shielding has recently attracted widespread attention. Herein, a facile strategy with (3-mercaptopropyl)trimethoxysilane (KH590) as a surfactant is used to synthesize one-dimensional (1D) PbWO4 structures. Their morphology evolution and crystal phase transition are traced during the growth process by SEM, TEM, and XRD techniques, respectively. The results show that monoclinic PbWO4 nanofibers with typical single-crystal attributes and high production are obtained with the addition of 5 wt% KH590. In addition, although PbWO4 nanoparticles display a slightly high attenuation coefficient for gamma radiation, 1D PbWO4 structures exhibit better thermal conductivity, tensile strength and elongation at break. These findings indicate that the prepared 1D PbWO4 structures have a very promising prospect in the application of state-of-the-art shielding materials for gamma radiation. [ABSTRACT FROM AUTHOR]
