A model to follow? The EU and global eco-social policy

In this article, we study the political project promoted by the European Commission (EC) for tackling simultaneously socioeconomic and environmental issues. Based on a detailed analysis of the most relevant EC policy documents (adopted between 2000 and 2020) that explicitly articulate ecological and socioeconomic questions, we offer two contributions to the literature on eco-social policy. First, we identify the nature of what we call the ‘European Eco-Social Model’. This political project subordinates social-ecological goals to the economic rationality of growth, competitiveness and profits and de-politicizes the efforts to promote more sustainable societies and economies. Second, we show how the Commission is repositioning itself as a global leader in the transformation to sustainability, attempting to extend its particular eco-social model to the whole world. Overall, we argue that this ‘model’ is based on self-contradictory assumptions and cannot demonstrate how it should be able to solve problems of social inequality and climate change on a global level.

Harmonious passion and academic achievement in higher education: The mediating influence of exploratory and exploitative learning strategies

Harmonious passion refers to engaging in an activity out of personal volition and sense of meaning, which motivates individuals to devote substantial time and energy while internalizing the activity as part of their identity, and it underpins the promotion of sustainable behaviors and mindsets. The present study aimed to investigate the relationship between harmonious passion and academic achievement among university students in higher education, as well as the mediating role of exploratory and exploitative learning behaviors in this association. Exploratory learning involves seeking new knowledge and skills, whereas exploitative learning involves refining and applying existing knowledge and skills. Data were collected from 528 university students across multiple institutions in China. Using structural equation modeling and multiple regression analysis, results revealed that harmonious passion had a significant positive effect on academic achievement. Furthermore, exploratory and exploitative learning played a chain-mediated role in the relationship. These findings provide insights into how harmonious passion could promote students' academic success in the context of innovation-driven and socially sustainable development, via the facilitation of sustainable learning strategies. Therefore, this study has broader implications for personal and societal sustainability, by emphasizing the role of harmonious passion and sustainable learning strategies in enhancing academic achievement and, ultimately, contributing to a more sustainable society.

Avogadro Colloquia in Rome on “Vision and Opportunities of a Sustainable Hydrogen Society”

Abstract The fifth edition of Avogadro Colloquia entitled “From Water to Chemicals: Vision and Opportunities of a Sustainable Hydrogen Society”, jointly organized by the Department of Chemical Sciences and Materials Technologies of the National Research Council (DSCTM CNR) and the Italian Chemical Society (SCI), was held at the CNR headquarters in Rome on December 15th–16th, 2022. This relevant periodic conference of SCI also was one of the first events for the celebrations of the Centenary of the Italian CNR. This edition of the Colloquia was focused on the technologies for hydrogen production and use in the so-called green transition towards a society with reduced CO2 emissions. Such technologies well fit the objectives recommended by the United Nations and by Mission EU2030 for the mitigation of the climate change. Greeting addresses to this event were given by the CNR president Maria Chiara Carrozza, the president of SCI Gaetano Guerra, the elected president of the European Chemical Society (EuChemS) Angela Agostiano, the IUPAC president Javier García Martínez and the director of DSCTM CNR Lidia Armelao. All the representatives of the national and international chemical societies underlined the key role of chemical sciences and innovative materials in the green transition.

Photocatalytic Dinitrogen Reduction to Ammonia over Biomimetic FeMoSx Nanosheets.

Reduction of atmospheric dinitrogen (N2) to ammonia (NH3) using water and sunlight in the absence of sacrificial reducing reagents at room temperature is very challenging and is considered an eco-friendly approach to meet the rapidly increasing demand for nitrogen storage, fertilizers, and a sustainable society. Currently, ammonia production via the energy-intensive Haber-Bosch process causes ∼350 million tons of carbon dioxide (CO2) emission per year. Interestingly, natural N2 fixation by the nitrogenase enzyme occurs under ambient conditions. Unfortunately, N2 fixation on biomimetic catalysts has rarely been studied. To mimic biological nitrogen fixation, herein, we synthesized the novel iron molybdenum sulfide (FeMoSx) micro-/nanosheets via a simple hydrothermal approach for the first time. Further, we successfully demonstrated the photochemical conversion of N2 to NH3 over a biomimetic FeMoSx photocatalyst. The estimated yield is around 99.79 ± 6.0 μmol/h/g photocatalyst with a quantum efficiency of ∼0.028% at 532 nm visible-light wavelength. Besides, we also systematically studied the influence of key factors to further improve NH3 yields. Overall, this study paves a new pathway to fabricate carbon-free, photochemical N2 fixation materials for future applications.

Review of the Mechanistic and Structural Assessment of Binders in Electrodes for Lithium-Ion Batteries

With the continual increase in CO2 levels and toward a sustainable society, developing high-performance lithium-ion batteries (LIBs) is crucial. A suitable electrode design is the key to enhancing the quality of battery cells (e.g., cycle retention characteristics and rate capabilities), and the binder plays an important role in providing sufficient adhesion between the active material, conductive agent, and current collector. Despite significant advances in the development of novel binder materials and solutions that can be employed as anode and cathode materials, careful investigations and summaries of the assessment methods for binder materials remain lacking. In this review, we examine the different analyses used to assess the quality of binder materials and how they help in assessing the quality of the electrode design. In addition, future perspectives on binder assessment are presented, which can be applied to future research directed toward binder development for advanced LIBs or post-LIBs.

Unveiling the effect of renewable energy and financial inclusion towards sustainable environment: Does interaction of digital finance and institutional quality matter?

Maintaining environmental sustainability has escalated to the top of the agenda in practically all nations today, including Pakistan. Hence, our research supports the United Nations sustainable development goal line, specifically SDG-11 for sustainable societies and SDG-13 for mitigating climate change vulnerability. To address these challenges, the present study investigates the association of digital finance, financial inclusion, renewable energy, and institutional quality with environmental sustainability in Pakistan. While financial inclusion is assessed using five proxies that are indexed by principal component analysis (PCA), digital finance is quantified by the number of ATMs. We used data from 2004 to 2021 to explore the relationship among the study variables. Employing the auto-regressive distributed lag (ARDL) model, we examined the long-run and short-run symmetric relationships between variables. Additionally, the study investigate the moderating impact on environmental sustainability by analysing the interaction term of institutional quality and digital finance (DF*INSQ). The results show that financial inclusion and digital finance can help developing countries like Pakistan achieve environmental sustainability. The study also highlights the vital role of renewable energy sources in the long-term reduction of carbon emissions. Moreover, the interaction between digital finance and institutional quality presents positive prospects for advancing environmental sustainability. These findings underscore the necessity of redefining financial inclusion and giving environmental sustainability projects top priority. They provide insightful information for policymakers and digital financial service providers in less developed countries. Furthermore, the study emphasizes the importance of robust financial institutions prioritizing renewable energy and institutional integrity for long-term financial health and growth.

This study proposes a green economy framework leading to Malaysia's green economy roadmap and raising society's sustainability awareness. The framework has catered actionable insight into promoting a green economy to industrial sectors by integrating Environmental, social, and corporate governance (ESG) and Sustainable Development (SD) principles to improve Malaysia's achievement of Sustainable Development Goals (SDGs). This paper has critically analyzeda systematic review from 2209 journal articles indexed from two prominent databases, Scopus, and Web of Science. The data were analyzed using visualizing bibliometric networks and a computer-assisted qualitative method. The thematic pattern result was verified and strengthened using in-depth interviews with industrial business leaders. The result shows that establishing a green economy framework should align with a clear regulatory policy and incentives. This study provided a unique combination of proposing a green economy framework employing advanced analysis techniques and providing specific recommendations for the Malaysian context. Adopting the green economy framework led by integrated ESG, SD, and SDGs would lead to Malaysia's Shared Prosperity Vision 2030. The public listed companies should step ahead in adopting green economy frameworks.

Giant nanomechanical energy storage capacity in twisted single-walled carbon nanotube ropes

A sustainable society requires high-energy storage devices characterized by lightness, compactness, a long life and superior safety, surpassing current battery and supercapacitor technologies. Single-walled carbon nanotubes (SWCNTs), which typically exhibit great toughness, have emerged as promising candidates for innovative energy storage solutions. Here we produced SWCNT ropes wrapped in thermoplastic polyurethane elastomers, and demonstrated experimentally that a twisted rope composed of these SWCNTs possesses the remarkable ability to reversibly store nanomechanical energy. Notably, the gravimetric energy density of these twisted ropes reaches up to 2.1 MJ kg−1, exceeding the energy storage capacity of mechanical steel springs by over four orders of magnitude and surpassing advanced lithium-ion batteries by a factor of three. In contrast to chemical and electrochemical energy carriers, the nanomechanical energy stored in a twisted SWCNT rope is safe even in hostile environments. This energy does not deplete over time and is accessible at temperatures ranging from −60 to +100 °C.

Effect of Carbon Nanofiber Distribution on Mechanical Properties of Injection-Molded Aramid-Fiber-Reinforced Polypropylene.

The mechanical recycling of discarded plastic products as resources for environmental preservation has recently gained research attention. In this context, it is necessary to use waste materials for fiber-reinforced thermoplastics (FRTP). Glass and carbon fibers are often damaged by shear and compression during melt-forming processes. To achieve a sustainable society, it is necessary for thermal recycling to produce minimal to no residue and for mechanical recycling to maintain the length of fibers used in FRTP to preserve their performance as a reinforcing agent. Aramid fibers (AFs) do not shorten during the melt-molding process, and their composites have excellent impact strength. On the other hand, plastics reinforced with glass or carbon fibers are reported to have a superior strength and modulus of elasticity compared to aramid fibers. This study investigates the dispersion of a carbon nanofiber (CNF), a whisker, as the third component in aramid-fiber-reinforced polypropylene (PP/AF). The results and discussion sections demonstrate how the dispersion of CNF in PP/AF can enhance the mechanical properties of injection-molded products without compromising their impact resistance. The proposed composition will have excellent material recyclability and initial mechanical properties compared to glass-fiber-reinforced thermoplastics.

Green nanomaterial-based adsorbent for Cs and Pb removal: Synthesis from industrial waste producing high-value products

ABSTRACT The search for a sustainable society makes necessary the reuse of residues contributing to the producing high-value product. Producing new materials with high-added value increases technological development and builds up new applications. The present study aimed to use residue from the alumina industry and coal ash generated in thermal plants in energy production to synthesize zeolite for wastewater treatment to remove Cs and Pb. Two types of nanomaterials were synthesized: zeolite 4A (ZEA) and zeolite sodalite (ZSD). The Cs adsorption efficiency achieved 73% and 9.4% for ZEA and ZSD, respectively, fitting better for Lineweaver-Burk isotherm and both zeolites removed 100% of Pb from synthetic solutions. Results here reported may be used to design novel wastewater treatment systems from nuclear plants and other industrial processes. The present study can contribute to achieving Sustainable Development Goals 9, 11, and 12.

Project-Based Learning methodology (PBL) for the acquisition of Transversal Competences (TCs) and integration of Sustainable Development Goals (SDGs) in mechanical engineering subjects

This research is carried out within the framework of a two-year Educational Innovation and Improvement Project (EIIP) to be implemented at the Universitat Politècnica de València (UPV) during the academic years 2023-2024 and 2024-2025. The project aims to design and apply a Project-Based Learning methodology (PBL) for a proper acquisition of Transversal Competences (TCs) and integration of the Sustainable Development Goals (SDGs) in a mechanical engineering subject that is taught in the first year of the master’s degree in Mechatronic Engineering from the School of Design Engineering. Based on an assessment by the teaching staff of the current situation and the aspects to be improved, this article explains how the PBL methodology will be applied and performs an analysis through surveys and personal interviews with the students of their level of knowledge regarding the TCs and the SDGs that are worked on in the subject at the beginning of the academic year. The results show the need to continue working in the project and implementing active teaching techniques, such as PBL methodologies, to achieve a more attractive and motivating subject, closer to the labour market and a sustainable society.

Including Sustainable Development in Automatic Control Courses

The automatic control subject has several connections to sustainability and can play an important role in the strive towards a more sustainable society. An example of how sustainability is included in a basic course in automatic control is presented, where the links between the degree requirements, sustainability and the subject are illustrated using The Global Goals for Sustainable Development (SDGs). The key idea is to present real world application examples where automatic control is a vital component and there are clear connections to the SDGs. The examples are inspired and illustrated using videos and images taken from the internet. Several times during the course a part of the lecture time is used to show a video, describe how the control subject comes in, and how the use of feedback control via the application can contribute to the fulfillment of the SDG.

Regulation of Hard Segment Cluster Structures for High-performance Poly(urethane-urea) Elastomers.

Elastomers are widely used in daily life; however, the preparation of degradable and recyclable elastomers with high strength, high toughness, and excellent crack resistance remains a challenging task. In this report, a polycaprolactone-based poly(urethane-urea) elastomer is presented with excellent mechanical properties by optimizing the arrangement of hard segment clusters. It is found that long alkyl chains of the chain extenders lead to small and evenly distributed hard segment clusters, which is beneficial for improving mechanical properties. Together with the multiple hydrogen bond structure and stress-induced crystallization, the obtained elastomer exhibits a high strength of 63.3MPa, an excellent toughness of 431MJm-3 and an outstanding fracture energy of 489kJm-2, while maintaining good recyclability and degradability. It is believed that the obtained elastomer holds great promise in various application fields and it contributes to the development of a sustainable society.

Carbon-oriented pricing scheme in digitalized power transmission networks utilizing carbon-driven demand response program under risk investigation

The main challenge for future sustainable societies is dealing with the high portion of released CO2 throughout smart power transmission systems; consequently, a comprehensive carbon-based framework is required that directly calculates stakeholders' contribution to the network's CO2 emissions. In this case, this paper proposes a mechanism driven by the carbon-tracing (CTR) process to tackle carbon emissions in smart transmission networks. Using the CTR mechanism enables the digitalized independent system operator (ISO) to allocate the total emissions among participants using the real-time data received from smart grid infrastructures. Furthermore, a carbon-based nodal pricing mechanism for gas and power systems is proposed, which reflects the received data from CTR analysis. To reduce carbon emissions in the smart power transmission network, a carbon-based demand response (DR) procedure is suggested, under which consumers will receive higher incentives for reducing their consumption, especially in high-carbon-intensity buses. In addition, in this paper, for effective management of carbon pollution, the uncertainties of wind and loads and leading risks to carbon and operation costs have been modeled. Hence, the conditional value-at-risk (CVaR) method is utilized for modeling the risks related to uncertainties. It can be seen that applying the proposed CVaR-based risk assessment framework and carbon-incentive-based DR programs led to a decrease in daily total carbon and operation costs by 0.66% and 1.02%, respectively.

Lost opportunities for globalisation, digitalisation, and socially sustainable education? Advocating for digital and global Bildung in Swedish upper secondary schools

In this article, we point to how the making visible of diverse linguistic, digital, and cultural competences can contribute to more sustainable and inclusive classroom contexts and future societies. Western notions of universal knowledge reproduces a western way of viewing the world and, as a result, this usually discounts alternative knowledge systems, which perpetuates inequality and may cause tensions in today’s diverse classrooms. Our 2022 pilot study, drawing on an online survey with more than 700 respondents and focus group interviews with 27 participants, indicates that for some multiethnic, multi-abled, and otherwise diverse upper secondary students underlying, often ethnocentric, norms of Swedish education create hurdles in educational contexts. Firstly, in the Swedish context, non-normative and often global experiences are not recognised at school. Secondly, topics addressed in the courses they take are primarily focused on aspects originating in a Swedish, Nordic, or Western tradition. Curricular policies and classroom practices must take lost opportunities, which we argue are not socially sustainable, into account as a more global and holistic approach when articulating what educational learning is supposed to be about, for, and for whom, and thus integrating learning, digitalisation, and social sustainability.

How to Enhance Public Participation in Environmental Governance? Evidence from China

Public participation in environmental governance plays a pivotal role in fostering a healthy and sustainable relationship between society and the environment. Despite the convenience afforded by the internet, the level of participation among Chinese citizens remains notably low. Thus, enhancing public enthusiasm for environmental governance is imperative, particularly given the paucity of academic research in this area. To address this gap, we employed the volume of messages on a leadership message board as a proxy for measuring the motivation behind public participation in environmental governance. Utilizing a provincial panel regression analysis, we investigated the determinants of public participation and subsequently conducted a mechanism analysis. Our findings reveal that deteriorating local air quality correlates with heightened motivation for public involvement in environmental governance. Additionally, increased public attention to environmental issues significantly amplifies this motivation, with the availability of internet access and the degree of emphasis placed by local governments on public participation further facilitating this process. This study contributes a theoretical and empirical foundation for enhancing public engagement in environmental governance, thereby fostering the development of a sustainable society.

Interlinking electronic band properties in catalysts with electrochemical nitrogen reduction performance: a direct influence

Abstract The wordwide energy demands and the surge towards a net-zero sustainable society let the researchers set a goal towards the end of carbon cycle. This has enormously exaggerated the electrocatalytic processes such as water splitting, CO2 capture and reduction and nitrogen reduction reaction (NRR) as a safe and green alternative as these involve the utilization of renewable green power. Interestingly, the NH3 produced from NRR has been realized as a future fuel in terms of safer green H2 storage and transportation. Nevertheless, to scale up the NH3 production electrochemically, a benevolent catalyst needs to be developed. More interestingly, the electronic features of the catalyst that actually contribute to the interaction and binding between the adsorbate and reaction intermediates should be analyzed such that these can be tuned based on our requirements to obtain the desired high-standard goals of NH3 synthesis. The current topical review aims to provide an illustrative understanding on the experimental and theoretical descriptors that are likely to influence the electronic structure of catalysts for NRR. We have widely covered a detailed explanation regarding work function, d-band center and electronic effect on the electronic structures of the catalysts. While summarizing the same, we realized that there are several discrepancies in this field, which have not been discussed and could be misleading for the newcomers in the field. Thus, we have briefed the limitations and diverging explanations and have provided a few directions that could be looked upon to overcome the issues.

Self-Powered Agricultural Product Preservation and Wireless Monitoring Based on Dual-Functional Triboelectric Nanogenerator.

The global annual vegetable and fruit waste accounts for more than one-fifth of food waste, mainly due to deterioration. In addition, agricultural product spoilage can produce foodborne illnesses and threaten public health. Eco-friendly preservation technologies for extending the shelf life of agricultural products are of great significance to socio-economic development. Here, we report a dual-functional TENG (DF-TENG) that can simultaneously prolong the storage period of vegetables and realize wireless storage condition monitoring by harvesting the rotational energy. Under the illumination of the self-powered high-voltage electric field, the deterioration of vegetables can be effectively slowed down. It can not only decrease the respiration rate and weight loss of pakchoi but also increase the chlorophyll levels (∼33.1%) and superoxide dismutase activity (∼11.1%) after preservation for 4 days. Meanwhile, by harvesting the rotational energy, the DF-TENG can be used to drive wireless sensors for monitoring the storage conditions and location information of vegetables during transportation in real time. This work provides a new direction for self-powered systems in cost-effective and eco-friendly agricultural product preservation, which may have far-reaching significance to the construction of a sustainable society for reducing food waste.

Application of MOFs-membrane in post-combustion carbon capture for electricity and thermal energy plants

Greenhouse gas emission typically carbon dioxide which result to global warming is becoming a very acute issue to human society. In order to achieve a sustainable development and society, various approaches to reduce carbon emission have been investigated and applied to industry where the majority of carbon emission happens in recent decays. Carbon capture is one of the key ways to address the emission and widely applied to coal-fired power plants. However, typically carbon capture process requires high energy input during the absorption and desorption process with lead to a low net carbon captured rate and high cost of operation. Materials with low energy penalty and high carbon affinity is desired to address this problem. In this research, a more advanced material, metal-organic frameworks (MOFs), for carbon capture under post combustion condition is introduced and evaluated from single material and cooperating with mixed-matrix-membranes to achieve membrane separation. Furthermore, MOFs are usually lack of stability and CO2/H2O selectivity. CALF-20 as the solution to these problems will be introduced later.
