Fundamental studies on graphene (Gr) and its real device applications have been affected by unavoidable defects and impurities which are usually present in synthesized Gr. Therefore, post treatment methods on Gr have been an important subject of research followed by the community. Here, we demonstrate a post-treatment of cm-sized CVD-grown graphene in a Radio Frequency-generated low-pressure plasma of methane and hydrogen to remove oxygen functional groups and heal the structural defects. The optimum plasma treatment parameters, such as pressure, plasma power, and the ratio of the gases, are optimized using in-situ optical emission spectroscopy. This way we present an optimal healing condition monitored with in situ OES. A twofold increase in the conductivity of plasma-treated Gr samples was obtained. Plasma treatment conditions give insights into the possible underlying mechanisms, and the method presents an effective way to obtain improved Gr quality.

Health care providers need moral sensitivity to provide effective ethical care Since spirituality is an integral part of morality, and spiritual intelligence is the basis of an individual's beliefs that affect his performance, this study was conducted to determine the role of spiritual intelligence in moral sensitivity of nursing students. This is a cross-sectional descriptive study that was conducted in 2021. The target population was nursing students studying in the first semester of 2021-2022 in Yazd, of which 153 people were selected by simple random sampling. In order to data gathering, questionnaire of King's spiritual intelligence and Lutzen's moral sensitivity was used. The validity and reliability of the instruments have been determined in previous research. Data were analyzed using descriptive statistics (mean and standard deviation, frequency distribution) and inferential statistics (Pearson correlation test and T test) by SPSS software version 16. Results indicated the mean of moral sensitivity (64.24 ±10.46) and the mean of spiritual intelligence of nursing students (53.90 ±34.13) were moderate. There was no statistically significant relationship between spiritual intelligence and moral sensitivity (P=0.245). Therefore, it is necessary to conduct studies to investigate the mediating factors that may affect these variables for a better and deeper understanding.
