Work stress and caring intention among health care workers in Taiwan during the COVID-19 pandemic

Abstract Background Healthcare workers may feel stress when caring for patients suspected as having a highly infectious and novel disease, such as the coronavirus disease 2019 (COVID-19). Objectives This study aimed to identify the psychological responses and factors affecting these responses among healthcare workers in Taiwan during the COVID-19 pandemic. Methods Healthcare workers regardless of their experience in caring for COVID-19 patients in our hospital voluntarily participated in this cross-sectional study in April 2021. We used a self-assessment questionnaire with 70 items to identify the psychological responses and affecting factors. Results The experience of caring for COVID-19 patients was significantly associated with eight stressors, including “frequent modification of infection control procedures,” “worrying about being negligent and endangering coworkers,” “worrying about lack of manpower,” “being without a properly fitted environment,” “protective gears being a drag in providing quality care,” “protective gears causing physical discomfort,” “worrying about inflicting COVID-19 on family” and “worrying about nosocomial spread.” Using multivariate logistic regression, “switching thoughts and facing the situation with positive attitudes” (odds ratio: 2.974, P = 0.011), “ever caring COVID-19 patients” (odds ratio: 1.990, P = 0.018), “I felt scared” (odds ratio: 0.180, P < 0.001), and “I thought it is unlucky” (odds ratio: 0.492, P = 0.029) were identified as independent factors for the healthcare workers’ willingness to participate in future missions regarding infectious respiratory diseases. Conclusion The experience of caring for COVID-19 patients was significantly associated with several stressors related to psychological, practical, and environmental aspects, but not with immediate reactions to the mission. Experiences in caring for COVID-19 patients and positive attitudes could increase the healthcare workers’ willingness to participate in future missions regarding infectious respiratory diseases, and feeling scared and unlucky can reduce this willingness.

Link between obesity and growth in children and adolescents

Background: The increasing prevalence of childhood obesity is a global problem. Childhood obesity is associated with an increased risk of several metabolic complications such as insulin resistance, impaired glucose tolerance, and type 2 diabetes mellitus (T2DM). Moreover, childhood obesity plays a significant role in growth patterns.Current Concepts: Growth during childhood and adolescence is influenced by multiple factors, including genes, hormones, and environmental aspects. Excess adiposity can influence growth velocity and final adult height owing to changes in several hormonal parameters such as insulin, leptin, and ghrelin.Discussion and Conclusion: Obese children typically exhibit a tall stature during the prepubertal and pubertal periods, which resolves later in adolescence. In addition, increased obesity in children precedes advancements in skeletal maturation and leads to earlier onset of puberty. Although potential mechanisms have been hypothesized, those underlying the putative association between childhood obesity and growth remain unclear. Further studies are required to gain insight into the mechanisms underlying the growth patterns in children and adolescents with obesity.

Analysis of the sustainability index for ecologically low-input integrated farming: A comprehensive assessment of environmental, economic, and social impact

A comprehensive sustainability index was designed in this study to evaluate the effectiveness and environmental impact of ecologically low-input integrated farming systems. By integrating diverse agricultural practices while minimizing reliance on external, non-renewable resources, this approach aims to enhance ecological harmony and sustainability. The index provides a multi-dimensional assessment, encompassing environmental, economic, and social aspects, to gauge the overall sustainability of these integrated farming practices. The procedure involved defining critical sustainability criteria across environmental, economic, and social dimensions, collecting relevant data on farming practices, and constructing a model to assess and score these practices. The index was validated through real-world applications and engaged with various stakeholders for insights and practical verification. Environmental data involves measuring soil nutrients (5 %), water usage (500 gallons/acre), and biodiversity (30 species/acre) to assess the ecological impact of farming practices. Economic data focuses on recording crop yields, input costs, and market prices to evaluate the financial viability of these practices. Social data is collected through surveys on labor practices, job satisfaction, and community impact, providing insights into the social implications and acceptability of the farming methods. The data revealed that the farming system aligned well with sustainability benchmarks, exhibiting no deviation from optimal levels in soil nitrogen content and water usage. Strong profitability and input cost efficiency were observed in the economic dimension, with a net income per acre of $400/acre and an input cost efficiency of 50 %. In the social aspect, although reasonably scored, specific labor metrics and regional/industry standards were lacking for a comprehensive evaluation. Overall, the farming system demonstrated commendable sustainability practices, with an environmental score of 7.5/10, an economic score of 8/10, and a social score of 7/10, suggesting potential for further improvements, particularly in addressing social sustainability factors.

How Does The Public Respond To The Impact Of Carbon Tax Implementation Planning In DKI Jakarta?

Implementing a carbon tax is a policy to overcome the impact of carbon emissions on the decline in environmental quality. Implementing carbon tax policies can have complex impacts in various fields, such as economic, environmental, social, and political. This research analyzes the public's open response to the impact of carbon tax implementation. The research uses a qualitative and S-O-R method to analyze the public's response to the carbon tax. Data collection methods are carried out through interviews, observation, and documentation. The criteria for selecting sources (informants) in this research are people in DKI Jakarta who have an NPWP (Tax ID number), owners, and users of motorized vehicles, as well as academics in the field of taxation. Data analysis was done in data reduction, display, and conclusion. The analysis results in this research show that most people respond to implementing the carbon tax by agreeing with income redistribution as a reduction in rates for other types of taxes. In the environmental aspect, there is a positive response to implementing a carbon tax in reducing the impact of carbon emissions. Various responses highlighted the principles of justice regarding social inequality between social groups and the need to evaluate policy instruments in socio-political aspects. Public approval for implementing a carbon tax considering economic changes and environmental awareness still underlines the need for a fairer socio-political approach.

Assessing the Healthfulness of University Food Environments: A Systematic Review of Methods and Tools

The availability, promotion, and price of healthy foods within the university food environment may impact students’ dietary choices. This systematic review summarizes the tools and methods used to assess the healthfulness of university food environments where many students spend a significant portion of their emerging adulthood. Thirty-six global studies published between 2012 and 2022 were sourced from PubMed (NNLM), Cochrane Library (Wiley), Web of Science (Clarivate), APA PsycInfo (EBSCO), CINHAL Complete (EBSCO), ProQuest Nursing, and Allied Health, following PRISMA 2020 guidelines. Of the included studies, 58% were institutional-level audits, 17% examined individual-level perceptions, and 25% combined both. Most institutional-level audits focused on one aspect of the food environment (e.g., eateries, vending machines). For studies examining multiple spaces within the campus environment (38%), comprehensive assessments were limited, and most studies had to employ a combination of assessment tools. Surveys were most often used to gather individual perceptions about the food environment. The Nutrition Environment Measures Survey (NEMS) was the most commonly used tool across all studies. This review highlights the need for a standardized tool, method, or a “healthy” benchmark for specific use at universities to improve methodological rigor and comparability of findings across institutions.

Edible insects as a sustainable protein source: a meta-analysis

Abstract With the global population set to reach 9.7 billion by 2050, posing a potential 75% increase in food demand, this study examined the viability of edible insects as a sustainable protein source compared with beef. Employing a meta-analysis approach, data were synthesized from studies conducted over the past 13 years, using Hedges’ d effect size and mixed model methods. The parameter values included the nutritional, environmental, and economic aspects of edible insects. Out of 10,119 articles screened, 222 were selected for analysis, revealing 135 different species. Subsequently, 10 species were selected, based on the most comprehensive data available, for mixed model analysis. Although the protein content of these 10 edible insect species was generally lower than that of beef, certain species exhibited amino acid scores surpassing those of beef. Edible insects also exhibited significantly higher calcium, iron, and zinc content compared with beef. Environmental aspects may enhance the value of edible insects as they exhibited greater advantages compared with beef. Despite some identified risks in incorporating edible insects into the diets of humans and animals, there remain potential areas for further investigation and development, such as addressing fat content, indigestible carbohydrate, availability, and sustainability aspects. Further research is required to promote local edible insect products as nutritious food and feed.

Melatonin in Human Breast Milk and Its Potential Role in Circadian Entrainment: A Nod towards Chrononutrition?

Breastfeeding is the most appropriate source of a newborn’s nutrition; among the plethora of its benefits, its modulation of circadian rhythmicity with melatonin as a potential neuroendocrine transducer has gained increasing interest. Transplacental transfer assures melatonin provision for the fetus, who is devoid of melatonin secretion. Even after birth, the neonatal pineal gland is not able to produce melatonin rhythmically for several months (with an even more prolonged deficiency following preterm birth). In this context, human breast milk constitutes the main natural source of melatonin: diurnal dynamic changes, an acrophase early after midnight, and changes in melatonin concentrations according to gestational age and during the different stages of lactation have been reported. Understudied thus far are the factors impacting on (changes in) melatonin content in human breast milk and their clinical significance in chronobiological adherence in the neonate: maternal as well as environmental aspects have to be investigated in more detail to guide nursing mothers in optimal feeding schedules which probably means a synchronized instead of mistimed feeding practice. This review aims to be thought-provoking regarding the critical role of melatonin in chrononutrition during breastfeeding, highlighting its potential in circadian entrainment and therefore optimizing (neuro)developmental outcomes in the neonatal setting.

Incorporating plastic waste fibres for sustainable sandy soil

The increase in urbanization has led governments to build on sites with certain geotechnical ‎hazards, such as liquefaction, ‎low bearing capacity, etc. In recent decades, as governments ‎have focused their efforts on the environmental and ‎economic aspects, researchers have ‎emphasized the need to use suitable alternative materials for the best design features, also the issue of plastic pollution is a significant global problem that requires urgent attention, current initiatives focus on the use of technical solutions to integrate non-biodegradable plastics into ‎the construction of buildings and road pavement.‎ ‎In this ‎paper, a series of direct shear tests were performed to evaluate the benefits of plastic wastes, ‎such as polypropylene ‎‎(PP) pots, and the engineering properties of sand reinforced with such ‎materials. To highlight the contribution of the ‎reinforcement to the shear strength, the ‎tests were carried out on sand reinforced with variable fibre contents (0.2, 0.4, 0.6, ‎and 0.8%) ‎for loose-density sand and medium-density sand. ‎ The experimental results showed that the increase in shear ‎strength is relatively more significant for specimens prepared with dry deposition mode as compared to those prepared ‎with wet deposition mode and it is increased with the fibre content. The inclusion of randomly distributed fibres has a significant effect on the shear strength and dilatation of sandy soils. Furthermore, the recycling fibre used in this study ‎shows a better performance in terms of shear strength. In conclusion, the use of plastic waste as ‎reinforcement would lead ‎to at least two solutions: soil reinforcement and reducing the ‎environmental impact of waste.

A challenge to the expected: Lack of longitudinal associations between the early caregiving environment, executive functions in toddlerhood, and self-regulation at 6 years.

Previous research and theory indicate an importance of the quality of the early caregiving environment in the development of self-regulation. However, it is unclear how attachment security and maternal sensitivity, two related but distinct aspects of the early caregiving environment, may differentially predict self-regulation at school start and whether a distinction between hot and cool executive function is informative in characterizing such predictions through mediation. In a 5-year longitudinal study (n=108), we examined these associations using measures of maternal sensitivity and attachment security at 10-12 months, executive function at 4 years, and self-regulation at 6 years. Surprisingly, and despite methodological rigor, we found few significant bivariate associations between the study variables. We found no credible evidence of a longitudinal association between maternal sensitivity or attachment security in infancy and self-regulation at 6 years, or between executive function at 4 years and self-regulation at 6 years. The lack of bivariate longitudinal associations precluded us from building mediation models as intended. We discuss our null findings in terms of their potential theoretical implications, as well as how measurement type, reliability, and validity, may play a key role in determining longitudinal associations between early caregiving factors and later self-regulation and related abilities. RESEARCH HIGHLIGHTS: The early caregiving environment has been implicated in the development of later self-regulation, which includes more basic skills, such as hot and cool executive functions (EF). In a 5-year longitudinal study, with a sample of 108 children, we rigorously measured aspects of early caregiving, EF, and self-regulation. We found no significant longitudinal associations between early caregiving and self-regulation at 6 years, nor between EF at 4 years and self-regulation at 6 years. These null results highlight the complexity of modeling self-regulation development and raise critical questions about general methodological conventions within self-regulation development research.

Assessing child satisfaction and expectations for developing a child-friendly environment at the pediatric department in a general hospital in Qatar

Background“Patient-centered” care positions the patient at the core and emphasizes fulfilling their unique needs, preferences, and values. This approach is particularly significant in the context of children. Although widely recognized as necessary, this approach is not universally implemented. The children find themselves in hospital wards where they are required to follow protocols and systems designed primarily for adults. In the appropriate atmosphere, children often express themselves more effectively through words, body language, and play, leading to a richer understanding of their needs. There is growing recognition of the importance of addressing children's concerns regarding hospital environments.AimThis study investigates children's satisfaction with the physical aspect of the hospital environment. Insights from this exploration could provide valuable input for creating hospital environments centered around children's needs and preferences.MethodsThis mixed-methods study involves children aged 6–14 years with parental consent from a premiere healthcare provider in the state of Qatar. The survey used nine items to gauge satisfaction with the existing hospital environment as a “child-friendly hospital” and another nine items to explore their expectations for such environments. The Mann–Whitney U and Kruskal–Wallis tests as well as thematic analyses were employed to assess the statistical significance of differences in satisfaction levels and children's expectations of the hospital's physical environment.ResultsA total of 398 children participated in the study. Of them, 40.3% were aged 6–8 years; 60.3% had experienced two to five hospital visits; 55.8% of children participated during their outpatient service visit; and 31.7% were Asian. Children's satisfaction levels with various aspects of the hospital environment—including its physical appearance, signage, lounge, consultant rooms, corridors, bedrooms, TV content, toys, and staff uniforms—were in the range of 42.9%–59%. The children expressed a desire for a hospital environment that is spacious, colorful, attractive, and filled with cartoon characters and toys in the children's hospital from the front lounge to the inpatient units.ConclusionThe findings underline the importance of considering the perspectives of children in evidence-based healthcare design. The study reveals that children's satisfaction with the hospital environment is generally average or below average. Ultimately, a “child-friendly hospital environment” integrates children's rights into healthcare to significantly improve outcomes.

Sustainability in a broad sense: An essential aspect of scientific conferences.

This article reflects on sustainability in the context of scientific conferences with emphasis on environmental, diversity, inclusivity, and intellectual aspects. We argue that it is imperative to embrace sustainability as a broad concept during conference organization. In-person conferences have an obvious environmental impact but mitigating strategies can be implemented, such as incentivizing low-emission travel, offering fellowships to support sustainable traveling, and promoting use of public transport or car-pooling. Utilizing eco-conscious venues, catering, and accommodations, along with minimizing resource wastage, further reduces environmental impact. Additional considerations include facilitating hybrid format conferences that allow both in-person and online attendance. Hybrid conferences enhance global participation whilst reducing resource consumption and environmental impact. Often-overlooked benefits can arise from the simple recording of talks to enable asynchronous viewing for people unable to attend in person, in addition to providing a legacy of knowledge that, for example, could support the training of early career researchers (ECRs) or newcomers in the field. The longevity of a research field, intellectual sustainability, requires an inclusive conference atmosphere, offering optimal opportunities for ECRs, minority groups, and researchers from emerging countries. Diversity and inclusivity not only enrich conference experiences but also enhances creativity and innovation.

Effectiveness of Soil-amended Biochar in Improving Crop Production, Soil Health and Environmental Aspects

Sustainable agriculture has assumed greater importance in today’s world. Biochar has the potential to increase crop yield and soil fertility in agriculture while reducing greenhouse gas emissions at the same time. Biochar production technology and biomass type has great influence on its quality and yield which in turn is responsible for altering soil fertility status and enhancing other soil properties. Biochar is produced via thermochemical conversion of biomasses by the process of pyrolysis with different pyrolysis conditions which include heating rate, temperature or residence time that affect the product distribution and yield for biochar produced from same biomass. Biochar is produced sustainably from eco-friendly sources under manageable conditions such as agricultural woody and non-woody wastes or crop residues or animal wastes. Biochar’s acknowledgement in removing heavy toxic metals, organic solvents and pesticide residues from soil as well as in waste water management aids in environmental protection. Yield response of biochar produced from various feedstock sources on vegetable crop production is discussed to compare their relative effectiveness. Biochar is a carbonaceous substance produced that sequester carbon and remain in soil for thousands of years and thus offers stability in soil. Biochar as Negative Emissions Technology (NET) in removing CO2 from atmosphere and other greenhouse gases such as N2O and CH4 is a prominent methodology in mitigating serious concern of climate change. The objective of this review paper is to extensively justify the role and importance of biochar in agriculture and sustainable growth.

Decreasing the energy demand in public buildings using nature-based solutions: case studies from Novi Sad (Republic of Serbia) and Osijek (Republic of Croatia)

BackgroundNature-based solutions (NBS) in urban areas offer an opportunity to improve environmental conditions and to reduce CO2 emissions towards establishing climate-neutral cities in the next few decades. Furthermore, the implementation of NBSs—vertical or horizontal green infrastructures on public facilities—could in particular improve both climate, including outdoor thermal conditions on a micro-scale (especially during the summer season) and the energy demand of buildings as well as save heating energy during the winter period.ResultsOn both selected buildings, extensive green roofs were implemented as an NBS intervention. The analysed data were obtained using the monitoring systems (from 2019 to 2022) installed on two public buildings in Novi Sad (Republic of Serbia) and Osijek (Republic of Croatia), with a focus on climate/bioclimate characteristics and thermal transmission capacities. Four automatic weather stations (AWS) were used for microclimate monitoring, along with the heat flow meter (HFM) method, to measure the alterations in the thermal transmittance (U value) of a flat concrete roof before and after energy refurbishment and the installation of a green roof. The outcomes of this study show that the air temperatures (Ta) and globe temperatures (Tg) near the green roof are lower by 0–3 °C for Ta and by 0–16.5 °C for Tg than the values captured by the AWSs at other locations. An even more interesting fact is that the green roof has a constant cooling potential during tropical nights, and based upon this research, the cooling value is around 2 °C for Tg (the Ta value is not distinct). The thermal transmittance results show that more savings can be achieved by applying a green roof with an 8 cm thick substrate: U values decreased by 50–69%, as measured by two different heat flux sensors.ConclusionsNature-based solutions, such as the implementation of an extensive green roof, have positive effects on diverse aspects of urban environments and building energy savings, which are particularly evident in extreme seasons, both summer and winter. Applying the proposed monitoring and assessment system could help local communities in their efforts to reduce carbon-based emissions. This paper provides a good example of the implementation of NBSs on a local- and a micro-scale.

Перешкоди впровадженню теплових насосів у централізованому теплопостачанні

Today, heat pumps are recognized as one of the technologies that most contribute to the decarbonization of almost all spheres of modern society life, especially industry and energy. The integration of heat pumps into district heating is considered as an implementation of renewable energy technology that will enable the European Union (EU) to achieve its ambitious energy and climate policy goals for developing sustainable society. The purpose of this article is to analyze and systematize the EU experience in overcoming obstacles to the introduction of heat pump technologies in district heating and to determine the possibilities of its application in Ukraine. It was found that it is impossible to ensure the universal integration of heat pumps into district heating for all EU members, and an individual analysis is required for each EU country, taking all technical and environmental aspects into account. Obstacles to the large-scale implementation of heat pump technologies into district heating are of a complex nature. Complex obstacles require an integrated approach that simultaneously removes these obstacles and includes direct incentives, indirect taxes, technical standards, building codes, education, etc. An analysis of the experience of the EU countries (financial support, education and training, preferential tariffs for electricity for heat pump operation, EU regulations on energy efficiency of buildings, the EU directive on renewable energy sources, etc.) made it possible to identify obstacles to the widespread implementation of heat pumps in district heating. The main such obstacles are the high initial cost of heat pump equipment, the high cost of electricity, the high cost of connecting to electricity and heat networks, insufficient government incentives, the lack of domestic production of heat pumps and highly qualified personnel for their implementation. The proposed main preventive measures to overcome these obstacles are the creation of a State Program to stimulate the introduction of heat pumps; legislative support aimed at accelerating the introduction of heat pumps; creation of financial incentives for their implementation; state stimulation of production of heat pump equipment and professional training of operating personnel. This article is aimed at discussing directions for the formation of effective legislative and regulatory measures for comprehensive stimulation of the large-scale introduction of heat pumps in the district heating in Ukraine. Keywords: heat pumps, renewable energy sources, district heating, implementation, obstacles, overcoming.

Investigation of performance and emission characteristics using ethanol-blended gasoline fuel as a flex-fuel in two-wheeler vehicle mounted on a chassis dynamometer

Abstract This study investigated the performance and emissions of flex fuels in a 110-cc BS6-compliant fuel-injected two-wheeler without ethanol adaptation adjustments. The tests were carried out under controlled conditions on a chassis dynamometer at 1000, 2000 and 3000 r.p.m. using ethanol blends from 10% ethanol (E10) to 85% ethanol (E85). Parameters examined included brake power (BP) output, brake-specific fuel consumption (BSFC), peak in-cylinder pressure and exhaust temperature. Emissions, including carbon monoxide (CO), hydrocarbons (HC), nitrogen oxide (NOx) and unregulated emissions, were also assessed. As the percentages of the ethanol blend increased from E10 to E85, there was a noticeable improvement in power output. At 1000 r.p.m., the BP ranged from 2.4 to 4.6 kW for different blends. The BSFC and the peak in-cylinder pressure followed a similar pattern, indicating enhanced performance and fuel efficiency with higher ethanol concentrations. Interestingly, using E85 at 1000 r.p.m. resulted in a significant 41.08% reduction in exhaust temperature compared with E10, although this difference decreased with higher blend percentages. Furthermore, replacing E10 with E85 at 1000 r.p.m. reduced CO and HC emissions by 9.17% and 38.34%, respectively. In contrast, NOx emissions increased at all r.p.m. levels with higher-ethanol blends, peaking at a 415 parts per million increase at 3000 r.p.m. However, unregulated emissions decreased significantly with increased r.p.m. and ethanol content. In summary, the use of flex-fuel blends in a two-wheeler resulted in a modest increase in BP output, improved fuel efficiency and lower CO and HC emissions. These findings are vital for optimizing ethanol blend utilization in two-wheeler engines under low-load conditions, considering both performance and environmental aspects.

Exploring Factors Influencing Students' Challenges in Academic Writing: A Qualitative Analysis Based on Student Perspectives

Writing proficiency poses significant challenges for learners of English as a Second Language (ESL) or English Foreign Language (EFL), particularly at the tertiary level where academic essay writing is a requirement. This study delves into the factors contributing to students' difficulties in an Academic Writing course, as perceived by the students themselves. Employing qualitative methods, including open-ended questionnaires and interviews, data were collected from 25 students enrolled in an Academic Writing class for repeaters in the English Language Education Program at a university in Hanoi. Thematic analysis of the responses revealed two main categories of factors influencing students' writing challenges: internal and external. Internal factors encompassed issues such as self-motivation, self-confidence, lack of knowledge, and feelings of pressure, while external factors included the teaching style of instructors, classroom environment, instructional materials, and various aspects of the writing process. The findings of this research aim to assist educators in developing effective teaching strategies for Academic Writing courses, with the goal of alleviating students' difficulties and enhancing their writing proficiency.

Building a resilient future: collaborative sustainability regulation

Abstract The challenge of sustainability lies in achieving a balance between satisfying present needs and protecting resources for future generations with an emphasis on its three pillars—environmental, social and governance. This study explored sustainable development encompassing environmental, social and governance aspects along with sustainability reporting through various sustainability frameworks. A systematic review of literature for the period 2010–23 on major worldwide sustainability frameworks was conducted, by offering insights into enhancing reporting mechanisms for a sustainable future. Secondary data related to sustainability reports were obtained from the Sustainability Accounting Standards Board and International Integrated Reporting Council, which helped in examining sector and year variations across countries. The results reflected that mandatory sustainability disclosures help to meet the United Nations Sustainable Development Goals and global sustainability frameworks help to set standards, disseminate information and promote transparency. Collaboration of investment, company action and sustainability organizations can lead to a sustainable global economy. The adoption of sustainability reporting can help organizations by fostering a proper understanding of sustainability practices, improving transparency and identifying potential business opportunities in sectors with lower sustainability. The paper provided insights into sustainability reporting published across various countries in both advanced as well as emerging and developing economies. The analysis showed which sectors and time periods have had the most sustainability reports and which areas needed to be targeted for action to advance sustainable development.

Electroneutralization desalination with spontaneous chemoelectric power generation

This study designs a novel electroneutralization desalination cell using reaction heat from acidic-alkaline wastewater neutralization to desalinate wastewater and generates chemoelectric power. Several key performance indicators are measured in terms of the energy, environmental and economic aspects of the system, including the ionic flux, the electrical energy produced, the electrical energy consumption for desalination, parasitic losses, overall energy conversion efficiency and desalination performance. The maximum peak power density is ∼31.5 mW/cm2 at 83.5 mA/cm2 and the desalination efficiency is 62 % using brine. The overall energy conversion efficiency is ∼81.8 % and the desalination followed the zero-order reaction. Assuming a 1.5 million litres per day treatment capacity integrated with reverse osmosis, the system has environmental and economic benefits, with 44.5 kg-CO₂eq greenhouse gas emissions per cubic meter of treated brine, and a discounted payback period of 4.2 years. This study demonstrates a pioneering electroneutralization technique for self-sufficient brine valorization and wastewater reclamation.
