Adsorption and Sensing Performances of a TiO2 Cluster-Doped Graphene Monolayer toward SOF2 and SO2F2.

Due to the high surface activity of metal atoms, it is difficult for doped metals to maintain long-term stability. Compared with other metal oxides, TiO2 graphene sensors have a higher sensing response and a larger specific surface area. However, there is currently no literature comparing and analyzing the effect of graphene-doped TiO2 on the adsorption performance of SF6 decomposition components. Therefore, this article investigated the adsorption performance of SF6 decomposition products: the distribution of SOF2 and SO2F2 on nTiO2 (n = 1,2,3)-doped graphene. In order to explore the interaction mechanism between gas molecules and these modified systems, their Eads, charge transfer, DOS, and PDOS were systematically studied. The doping of nTiO2 significantly improves the adsorption ability of graphene to gas molecules, discovers and enriches the online monitoring methods of GIS, and improves the engineering application value of GIS.

A cross-sectional survey on nurses in burn departments: Core competencies and influencing factors.

BACKGROUND: Nurses of burn departments play a vital role in caring for and rehabilitating burn patients. However, the situation of nurses in burn departments is seldomly reported. The current study aims to identify the status and influencing factors of nurses in burn departments' core competencies nationwide. METHODS: This is a cross-sectional and multicenter study. Purposive sampling was used to recruit registered nurses who worked in burn departments of 12 tertiary hospitals in Mainland China. We issued an online survey including structured questionnaires consisting of socio-demographic information and the Self-rating Scale for Core Competencies. RESULTS: Totally 267 nurses in burn departments participated in our study. The mean score of nurses in burn departments' core competencies was (3.81 ± 0.53), with a scoring rate of 76.22%. Professional title, length of employment and experiences in burn intensive care units (BICUs) were influencing factors of NBDs' core competencies (P < 0.05), explaining 21.0% of the total variance. CONCLUSIONS: Our findings indicate that the core competencies of nurses in burn departments were at a moderate level generally. Moreover, this study highlights that nursing administrators and educators should promote the specialized knowledge and skills, teaching skills and critical thinking of nurses in burn departments.

Symptom clusters in patients with colorectal cancer after colostomy: a longitudinal study in Shanghai.

OBJECTIVE: Research is lacking regarding the experiences of patients after colostomy, which is needed so as to take necessary specific actions. In this study, we aimed to describe the trajectory of symptom clusters experienced by patients after colostomy over time. METHODS: This was a longitudinal observational study using data from 149 patients with colorectal cancer after colostomy. We investigated symptoms and symptom clusters at 2 weeks, 1 month, 3 months, 6 months, and 1 year after colostomy. RESULTS: Four main symptom clusters were identified, including a psychological symptom cluster, digestive and urinary symptom cluster, lack of energy symptom cluster, and pain symptom cluster in patients after colostomy in the first year after surgery. We further explored the symptom trajectory. CONCLUSIONS: We explored symptom clusters and the trajectory of symptom resolution in patients after colostomy during the first year after surgery. Four stages were proposed to describe the different statuses of symptom clusters experienced by patients. Our findings may provide insight into how to improve symptom management and postoperative quality of life for patients after colostomy.
