The wastewater contaminated by dyes contains many organic compounds, which have carcinogenic, mutagenic, and other effects, endangering human health. The traditional wastewater treatment methods have problems such as high cost, secondary pollution, difficulty in large-scale production, and complicated operation and management, which has restricted their wide use. In recent years, the research of adsorption technology on the treatment of dyeing wastewater is getting deeper. Membrane adsorption is an economical, convenient, and easy-to-operate technique, highly efficient for dye removal, and has been widely used for the treatment of wastewater.This research combined the protocol of electrospinning, crosslinking, and sulfonation modification to prepare hydrophilic polystyrene nanofibers, which improved the specific surface area of polymers, enhanced the stability and mechanical strength of nanofibers, and improved the hydrophilicity and adsorption capacity of nanofibers. Secondly, the morphologies, chemical structure, and wetting properties of the fibrous membranes were characterized; The adsorption effect of fiber membranes on methylene blue (MB) was also investigated; Finally, it was concluded that the fitted Langmuir model with a higher determination coefficient was more suitable to describe the adsorption behavior, which indicated that the adsorption of MB by fiber membranes was in the form of monolayer adsorption. The nanofibrous membranes prepared by this method can efficiently adsorb dye molecules, offer an effective scheme in the field of water treatment materials, and have great research value.

Developing global citizens has become a priority in nursing education worldwide. Since a limited number of students participate in face-to-face academic exchanges with a host institution, innovative educational approaches to bring the world to students are needed. Virtual global education (VGE) experiences offer opportunities for students from around the world to interact and learn from each other without packing a suitcase. While VGE's can improve learning while providing cost-effective, sustainable opportunities to increase accessibility to students and faculty from outside their native country, they require directed preparation, development, and planning. To develop VGE expertise in our faculty, we provided pilot funding coupled with a dedicated mentoring team to build our VGE teaching capacity and grow a cadre of committed, engaged and proficient experts in this aspect of academic internationalization. We built upon their broad plans, combining mentoring from a two-person team of experienced VGE faculty. Each project met different challenges along the way; however, both undergraduate and graduate students evaluated each VGE experiences with high levels of enthusiasm and positive learning outcomes. Each faculty will serve as mentors for the next year's awardees to build our collective expertise and develop successful VGE approaches to implementation and evaluation.

CO 2 separation plays a vital role in reducing CO 2 emissions to combat climate change, while the available technologies still face challenges, including high costs and intensive energy usage. It is still critical to develop an energy-efficient and cost-effective technology for CO 2 separation. Ionic liquid/deep eutectic solvent (IL/DES) has drawn significant attention in CO 2 separation because they are tunable and exhibit high thermal stability and high CO 2 solubility. The technologies based on IL/DES show their potential to reduce cost and energy usage. However, their viscosity is relatively high. In our work, adding cosolvents was used to adjust the high viscosity of IL/DES. A universal framework of IL/DES-based hybrid solvents for CO 2 separation, from properties determination, thermodynamic modeling, to process design and evaluation, has been built up. Several DESs/ILs interacted with CO 2 chemically and/or physically were investigated, aiming for the gas streams with different CO 2 concentrations (biogas, flue gas). A detailed comparison of the performance of IL/DES-based hybrid solvents in terms of energy usage and cost with respect to conventional solvents was provided to study their feasibility. Our research shows that IL/DES-based hybrid solvents are promising for CO 2 separation for different gas streams to reach the aim of lowing energy usage and cost, while further improvement is still needed to reach a technological breakthrough.

Capacitative deionization (CDI) technique is widely pursued for the removal and recovery of ionic contaminants from wastewater, as it does not leave secondary waste and can operate at low voltages < 1.2V vs. reversible hydrogen electrode (RHE) (Suss, 2015; Pastushok, 2019; Ge, 2018). Most studies in literature concentrate on desalination, however the removal of other ionic contaminants like nitrates, phosphates, sulphates, chlorides, and fluoride are also explored (Zhang, 2022; Zhang, 2023; Chen, 2022; Martinez-Vargas, 2022). In a previous work (Krishnamurthy, 2022), carbon-based electrodes were made from pine-based biomass and these electrodes were tested for their electrochemical properties, through a series of complementary experimental methods. The goal of the present work is to perform a techno-economic analysis (TEA) for the removal of ionic nitrate (NO3–) and phosphate (H2PO4–) contaminants from wastewater using the electrochemical properties. The basis for the design was the removal of nitrates and phosphates from a wastewater stream available at a flowrate of 44l/s and an initial nitrate and phosphate concentration of 1 mM. The final concentration was fixed to be 0.1 mM after the removal of the ionic contaminants. The TEA was based on the information obtained from the characterization of the electrodes. The results showed that CDI process was economical for nitrate removal compared to that of the phosphate removal due to the higher capacitance value. Sensitivity analysis was further performed to evaluate the effect of the capacitance, the electrode replacement and the outlet concentration on the capital and the operating expenditure values.

AimTo describe the experience of university leadership implementing Multi-Flexible Learning (M-Flex) to promote active teaching strategies and significant learning; and to discuss implications for the university and for the faculty of nursing. BackgroundM-Flex was developed to provide flexibility and facilitate significant learning during the pandemic. Physical, human, and technological resources were utilized to increase active teaching strategies. DescriptionImplementation of M-Flex required collaboration with university and faculty leaders. Online training sessions was provided to lecturers and students. To explore expectations of lectures and students, a survey was given during two different semesters. There was an expectation gap between lectures and students. Nursing students were more satisfied than other groups of students. ConclusionM-Flex and significant learning will continue to be emphasized after the pandemic. More training is needed on intentionally planning courses for significant learning. Utilizing a blended learning approach. Additional guidance will be provided for students regarding active participation in blended learning approaches. In nursing education, to meet the increased demand for nursing graduates, it is crucial for lecturers to develop a flexible, blended learning approach that allows for flexibility with students located in many locations.

AimThe purpose of this qualitative descriptive study was to explore nurse educators' perceptions of using best teaching strategies and practices for providing culturally sensitive and inclusive nursing education (CSINE). BackgroundThere is a need for CSINE to facilitate the successful completion of nursing programs by culturally diverse nursing students to prepare them to provide nursing care to patients and families in diverse communities. DescriptionNurse educators in an associate degree nursing program completed an open-ended question survey regarding best practices and challenges for implementing CSINE. Follow-up interviews provided additional depth to the findings. ResultsFour major categories developed from the educators' responses. Some benefits and outcomes of using CSINE were described. Educators also expressed a need for ongoing education regarding CSINE. ConclusionResults from the study can assist nurse educators in the academic and practice settings to implement best practices in providing CSICE and to overcome common challenges. It is important that educators are role models in demonstrating compassion, stewarding available resources, treating everyone with mutual respect, and teaching with excellence in a variety of learning environments. Implications for future research are discussed.
