Differences in Nurses' Satisfaction and Demand for Spatial Design Among Different Departments of Nursing Units: A Case Study in China.

OBJECTIVES: The study aimed to extend original research and identify operational and space-related requirements for specialization from the perspectives of nursing behavior and process. BACKGROUND: Studies related to the specialty of different nursing units have been widely conducted in nursing science, while few studies have explored the specialized requirements for the physical environments of nursing units in different departments. METHOD: Questionnaire survey data were collected from 125 nurses in 11 clinical departments, and nurse shadowing (approximately 68 hr) was conducted in four clinical departments. RESULTS: The questionnaire survey showed that satisfaction with care activity, visibility, and physical environment within the existing nursing unit environment was rated differently among different departments of nursing units. However, nurses in different groups of age, education, work experience, and position indicated no statistically significant difference. Behavioral observations demonstrated that the spatial and temporal distributions of activities, spatial linkages, and communication patterns varied in distinct departments. CONCLUSION: This research found that nurses in different departments had different evaluations of satisfaction and environmental characteristics. It also explains the differences in nursing work behaviors and processes found in various departments and sheds light on specialized requirements from the behavior perspective. The findings could help optimize the design of efficient and satisfactory nursing units in different departments.

Universal Strategy for Preparing Highly Stable PBA/Ti3C2Tx MXene toward Lithium-Ion Batteries via Chemical Transformation.

Prussian blue analogues (PBAs) are believed to be intriguing anode materials for Li+ storage because of their tunable composition, designable topologies, and tailorable porous structures, yet they suffer from severe capacity decay and inferior cycling stability due to the volume variation upon lithiation and high electrical resistance. Herein, we develop a universal strategy for synthesizing small PBA nanoparticles hosted on two-dimensional (2D) MXene or rGO (PBA/MX or PBA/rGO) via an in situ transformation from ultrathin layered double hydroxides (LDH) nanosheets. 2D conductive nanosheets allow for fast electron transport and guarantee the full utilization of PBA even at high rates; at the meantime, PBA nanoparticles effectively prevent 2D materials from restacking and facilitate rapid ion diffusion. The optimized Ni0.8Mn0.2-PBA/MX as an anode for lithium-ion batteries (LIBs) delivers a capacity of 442 mAh g-1 at 0.1 A g-1 and an excellent cycling robustness in comparison with bare PBA bulk crystals. We believe that this study offers an alternative choice for rationally designing PBA-based electrode materials for energy storage.
