“…Be- sides, the maximum adsorption capacity using the D-R isotherm was obtained 34.62 mg/g. 40,41 In addition, the Gibbs free energy (ΔG°) using the Langmuir model was determined -5.112 KJ/mol, which indicates the spontaneity degree of the sorption process. Also, negative value of ΔG° shows a favorable sorption process.…”

In the present work, methylene blue was eliminated from aqueous solution using activated carbon prepared by lotus leaves. To perform the experiments, batch method was applied. Also, several analyses such as SEM, FTIR, EDAX and BET were done to determine the surface properties of the activated carbon. The results showed that the maximum sorption efficiency of 97.59% was obtained in initial dye concentration of 10 mg/L, pH of 9, adsorbent dosage of 4 g/L, temperature of 25 °C, contact time of 60 min and mixture speed of 400 rpm. Furthermore, the maximum adsorption capacity was determined 80 mg/g, which was a significant value. The experimental data was analyzed using pseudo-first order, pseudo-second order and intra-particle diffusion kinetic models, which the results showed that the pseudo-second order kinetic model could better describe the kinetic behavior of the sorption process. Also, the constant rate of the pseudo-second order kinetic model was obtained in the range of 0.0218–0.0345 g/mg.min. Moreover, the adsorption equilibrium was well described using Freundlich isotherm model. Furthermore, the thermodynamic studies indicated that the sorption process of methylene blue dye using the activated carbon was spontaneous and exothermic.

“…The hydrophobic powders were fabricated based on our previous research with small modification. [ 34‐35 ] First, 0.5 g of FAS was dissolved in 10 g of THF and the mixed solution was magnetically stirred for 2 h. Then, 0.5 g of MWCNTs and 0.3 g of graphene were sequentially added to form a paint‐like suspension. In order to ensure the uniform distribution of MWCNTs and graphene in the suspension, this suspension was treated by ultrasonic for 0.5 h and then magnetically stirred for 4 h. In the next step, the suspension was poured into an evaporating dish.…”

Main observation and conclusion The superhydrophobic strain sensor is a fantastic direction, which could protect the strain sensor in harsh environment. Nevertheless, the self‐healing superhydrophobic strain sensor has not been reported. In this research, we developed a superhydrophobic strain sensor, which demonstrated excellent self‐healing, mechanical robustness, and liquid impalement resistance simultaneously. The key innovation is to partially embed hydrophobic graphene and carbon nanotubes into the hydrogel matrix. The hodrogel substrate endows the sample with self‐healing property. The graphene, carbon nanotubes and hydrogel together lead to an accurate and real‐time monitoring of human motion. Furthermore, the prepared sample demonstrated super‐robust superhydrophobicity, which retained superhydrophobicity after many kinds of damage (such as 1000% stretch, 10000 stretching‐releasing cycles, hand‐rub, tape‐peeling, and high‐speed drop/jet impact).

“…Research is shown that other aspects of employee behavior are important and depend on the effort of the staff members of the organization (Specht et al, 2007). Employee efforts to satisfy customers are more important than the capabilities they have previously received Wang et al (2021). Management should focus on the enhancement of staff effort.…”

Purpose The purpose of this paper is to focus on the emerging phenomenon of medical tourism in the context of Iran from a customer experience management perspective and benchmark of their judgment including positive or negative, of the experience they have achieved of the Iranian health (medical) experience (CE) and suggest scenarios for the improvement of the Iranian customer experience management (CEM). Design/methodology/approach The research methodologies and research methods that are used in this descriptive-analytical research are based on an inspection of the remarkable literature related to medical tourism and customer experience management. The data gathering instrument is a researcher-made questionnaire based on the variables in the conceptual model extracted from the research literature. The study was conducted from May to August 2019. The population cohort of this study was the foreign patients calling selected Iranian hospitals and the sampling method was a purposive and snowball sample of prospective medical tourists. As the study was conducted throughout Iran, some important hospitals in Iran were selected by stratified sampling Yang et al. (2020b). The sample size and data saturation were 500 participants Lv and Song (2019). The collected data using the questionnaire were analyzed by SPSS software and statistical tests. Findings According to the results, the customer experience management statistical significance in the task aspect is (p = 0.0523), in the mechanical aspect is (p = 0.0563), in the human aspect is (p = 0.0544). The study showed positive customer experience among the patients who had been treated in the Iranian hospitals. Originality/value There is a lack of study that focuses on medical tourism and customer experience management in Iran. Therefore, based on the results of this study, the experience of medical tourists in Iran proved to be positive and satisfying. As little research has been conducted in the area of customer experience management (CEM) in Iranian medical tourism, future researchers can use these valuable results precisely and in more detail to benchmark more accurately the customer experience in all areas of medical and health tourism and other research areas in different aspects of CEM in Iran.
