Facing persistent natural catastrophes, the necessity for disaster prevention products in afflicted cities becomes paramount. Modular design has proven to be a viable method for streamlining transportation and manufacturing processes for disaster prevention products. However, existing post-disaster prevention products often fail to incorporate the green modular concept, with limited research on spatial allocation strategies. In response to the current challenges, a new breed of green post-disaster prevention products is urgently warranted to mitigate the impact of major natural disasters and safeguard lives and property. To achieve the goal, this study employs a combined analytic hierarchy process (AHP) and geographic information systems (GIS) analysis to propose an inflatable cabin for emergency disaster prevention, specifically designed for flood scenarios. Using the inflatable cabin as an empirical case, this study introduces a layered design approach progressing from macro to meso and then to micro levels to construct an objective decision-making model to prioritize key design elements, develop spatial post-disaster prevention strategies, and analyze the mechanical performance. Results indicate that at a distance of 30 m from the base of the slope (SPIC), the impact force is most significant, reaching up to 1.8 × 10⁷ kN. As the distance increases from 30 m to 150 m, the maximum impact force decreases by an order of magnitude, and the average impact force decreases by approximately two orders of magnitude. Furthermore, this comprehensive approach, which starts from a holistic design perspective and culminates in optimizing individual disaster structures, offers practical significance for engineering design research.

Smart manufacturing encompasses a category of manufacturing that employs computer-integrated capabilities and technologies to enhance supply chain optimization, production efficiency, and recyclability. Yet, limited studies have been conducted to optimize these prospects from the perspective of low-resource countries where such innovative studies have not been adequately explored. This paper aims to examine the implications of smart manufacturing practices (Smart Procurement, Smart Supply Chain, Smart Production Planning and Control, Automation and Industrial Robot, and Supply Chain Configuration) on pro-environmental behaviour and develop a baseline moderated mediation model to explain the relationship between smart manufacturing and pro-environmental behaviour as well as the indirect effects of environmental awareness and green dynamic capability. This study employs a quantitative research approach, utilizing inductive reasoning and an explanatory design. Data from 382 manufacturing enterprises in Ghana were collected through a cross-sectional survey. We tested our hypotheses using SMART-PLS software version 3.8.9 and SEM technique. The study found a strong and positive relationship between smart manufacturing practices and pro-environmental behaviour. Additionally, the relationship between smart manufacturing and pro-environmental behaviour is influenced by green dynamic capacity and environmental orientation. The study’s implications involve the creation of a fundamental model that can assist policy makers, practitioners, and academics in understanding the connection between smart manufacturing and sustainable production in developing nations. Again, the social implication of the study includes the realisation of decent job and economic growth, responsible consumption, and production as well as actions taken to combat climate change.

The development of green innovation in the manufacturing industry is crucial for sustainability, as it can lead to significant environmental and economic benefits. Meanwhile, the impact of digital transformation on green innovation in the manufacturing industry has been proven to be significant in a previous study. To further explore the impact of digital transformation on the development of green innovation in the manufacturing industry under the dual carbon goal, this article selects data from Chinese A-share manufacturing listed companies from 2013 to 2022 as the observation sample, proposes research hypotheses based on stakeholder theory, and conducts empirical analysis. The results indicate that digital transformation can significantly promote the development of green innovation in the manufacturing industry, which is transmitted through corporate environmental responsibility. Corporate environmental responsibility plays a partial mediating role in the impact of digital transformation on the development of green innovation. Meanwhile, media attention can strengthen the positive impact of digital transformation on green innovation. In heterogeneity analysis, it was found that the higher the institutional shareholding and analyst attention, the more likely a company’s digital transformation can promote green innovation. In addition, by comparing and analyzing the data of the two years before and after the proposal of the dual carbon target, it was found that the incentive effect of the dual carbon target did not achieve the expected effect in this article, which may be related to the short time of the proposal of the dual carbon target and the impact of the epidemic.

As a fundamental unit of sustainable economic development, corporate green development is significantly influenced by entrepreneurs’ spirit and new-quality productivity. Therefore, it is crucial to explore the intrinsic connections among entrepreneurs’ spirit, new-quality productivity, and corporate green development. This study leverages data from 17,079 A-share manufacturing companies from 2012 to 2022. It employs a dual-dimensional fixed-effects model to investigate the mechanisms, pathways, and effects of entrepreneurs’ spirit on corporate green development, with new-quality productivity serving as a mediating variable. The findings reveal that (1) stability tests using the IV method and Heckman’s two-step method indicate that entrepreneurs’ spirit significantly promotes corporate green development; (2) mediation-effect tests show that new-quality productivity partially mediates the relationship between entrepreneurs’ spirit and corporate green development; and (3) heterogeneity-effect tests demonstrate that the promoting effect of entrepreneurs’ spirit on corporate green development is more pronounced in large enterprises compared to small- and medium-sized enterprises, in eastern enterprises compared to those in central and western regions, and in less competitive enterprises compared to more competitive ones. These conclusions not only enrich the research on corporate green development but also aid in the formulation of corporate-green-development strategies, thereby contributing to sustainable economic development.

Tea (Camellia sinensis) falls into the family Theaceae, is a valuable commercial crop, and tea products made from its buds and young leaves are favored by consumers all over the world. The more common Thea plant is Camellia sinensis (C. sinensis), but its most important relative, Camellia taliensis (C. taliensis), is also utilized by locals in the area of cultivation to manufacture tea. In this investigation, C. taliensis (DL) and C. sinensis (QJZ) were characterized in terms of their agronomic traits, physicochemical indices, metabolomics, and transcriptomics. The leaf area of DL is larger than that of QJZ; the color of DL’s buds and leaves is yellowish-green, while that of QJZ’s is green. DL’s buds and leaves are more densely velvety than those of QJZ. The HPLC results indicated that the physicochemical contents varied considerably between the two samples, with DL having greater concentrations of EGCG and GABA than QJZ, while QJZ had remarkably higher concentrations of C, CA, and EGC than DL. A total of 2269 metabolites and 362,190,414 genes were positively identified, with the number of DAMs and DEGs being 1001 and 34,026, respectively. The flavonoids, phenolic acids, and alkaloid metabolites were dramatically different between the two tea group plants. Bioinformatics profiling revealed that the DAMs and DEGs of the two tea group plants interacted with each other and were involved in metabolic pathways, including “biosynthesis of secondary metabolites”, “biosynthesis of amino acids”, “biosynthesis of cofactors”, “phenylpropanoid biosynthesis”, and “flavonoid biosynthesis”. Overall, these results provide statistical support for germplasm conservation and production for both C. taliensis and C. sinensis. Full article

Energy efficiency is widely recognized as the foundational and most critical strategy for decarbonizing the manufacturing sector. Misconceptions surrounding energy efficiency measures often hinder their widespread adoption. This article aims to debunk five common myths and provides data and resources to help implement efficiency projects faster and more effectively to achieve greater decarbonization. First, the article challenges the myth that organizations have exhausted all possible energy efficiency opportunities by achieving voluntary energy intensity goals or energy performance certification. Second, it also addresses the misconceptions that efficiency projects are capital-intensive, require many qualified specialists, and have long investment return periods. By presenting real-world case studies and referencing commonly found efficiency opportunities, the article illustrates that energy-savings opportunities are ubiquitous. Organizations can use various contracting mechanisms as well as financial and technical resources from utility companies and government programs to lessen their burden. The notion that efficiency measures can be implemented solely in proprietorship facilities is dispelled. This article emphasizes the importance of green leases and explains that aligning decarbonization goals between the lessor and lessee can help drive savings for both parties. Finally, using unbundled renewable energy certificates as the sole pathway to decarbonization is strongly discouraged. By debunking these prevalent myths, this article aims to foster a deeper understanding of energy efficiency’s potential as a cornerstone of decarbonization efforts and to embrace it as a critical pathway toward a sustainable future.

Ocean acidification has become a major climate change concern requiring continuous observation. Additionally, in the industry, pH surveillance is of great importance. Consequently, there is a pressing demand to develop robust and inexpensive pH sensors. Ratiometric fluorescence pH sensing stands out as a promising concept. The application of carbon dots in fluorescent sensing presents a compelling avenue for the advancement of pH-sensing solutions. This potential is underpinned by the affordability of carbon dots, their straightforward manufacturing process, low toxicity, and minimal susceptibility to photobleaching. Thus, investigating novel carbon dots is essential to identify optimal pH-sensitive candidates. In this study, five carbon dots were synthesized through a simple solvothermal treatment, and their fluorescence was examined as a function of pH within the range of 5–9, across an excitation range of 200–550 nm and an emission range of 250–750 nm. The resulting optical features showed that all five carbon dots exhibited pH sensitivity in both the UV and visible regions. One type of carbon dot, synthesized from m-phenylenediamine, displayed ratiometric properties at four excitation wavelengths, with the best results observed when excited in the visible spectrum at 475 nm. Indeed, these carbon dots exhibited good linearity over pH values of 6–9 in aqueous Carmody buffer solution by calculating the ratio of the green emission band at 525 nm to the orange one at 630 nm (${\mathcal{I}}_{525\mathrm{nm}}$/${\mathcal{I}}_{630\mathrm{nm}}$), demonstrating highly suitable properties for ratiometric sensing.

As manufacturing advances swiftly and public consciousness about low-carbon practices rises, eco-friendly supply chains have seen significant expansion. This study investigates a government-driven green supply chain in two phases, involving a producer and a seller. Four scenario game models are established to determine whether the manufacturer engages in green technology innovation or whether the retailer has altruistic preferences. The Stackelberg game was used to analyze changes in government carbon quota regulations, retail prices of retailers, and manufacturers’ carbon reduction efforts in the context of carbon market trading. Research shows that the government will set looser carbon emission limits for manufacturers when retailers have no altruistic preferences. When carbon prices in the market are low, encouraging manufacturers to invest in green technology innovation enhances social welfare. This study offers essential theoretical backing for the government in crafting carbon quota regulations and aids businesses in making prompt technological innovation choices. Full article

As environmental pressures intensify and digital technology advances rapidly, many countries, including China, are looking to more effectively heed social and environmental responsibilities by effectively integrating digital technology with traditional industries. Digital green innovation is gradually becoming a necessary direction for enterprises in various countries as they strive for high-quality development. How enterprises can achieve digital green innovation through the duality of digitalization and sustainability has become a crucial research question. However, existing research rarely addresses the mechanisms that lead to the formation of digital green innovation within enterprises. This study uses a sample of 305 manufacturing enterprises in China. Based on strategic orientation theory, this study introduces the concept of digital sustainability orientation, integrating both digital and sustainability orientations. A model is constructed to examine the impact of digital sustainability orientation on digital green innovation in enterprises, analyzing the mechanism of action through the mediation of capability reconfiguration and the moderation of environmental scanning. The study finds that digital sustainability orientation significantly positively impacts digital green innovation, highlighting the integrated effect of digital and sustainability orientations. The findings indicate that digital sustainability orientation significantly positively impacts digital green innovation, whereas a single strategic orientation does not effectively promote digital green innovation; capability reconfiguration partially mediates the relationship between digital sustainability orientation and digital green innovation in enterprises; and environmental scanning positively moderates the relationship between digital sustainability orientation and capability reconfiguration and further influences the mediating role of capability reconfiguration. This study contributes to the advancement of digital sustainability theory in the field of digital green innovation; moreover, the results of this study offer significant practical insights for enterprises aiming to successfully implement digital green innovation.

As the metal additive manufacturing (AM) field evolves with an increasing demand for highly complex and customizable products, there is a critical need to close the gap in productivity between metal AM and traditional manufacturing (TM) processes such as continuous casting, machining, etc., designed for mass production. This paper presents the development of the scalable and expeditious additive manufacturing (SEAM) process, which hybridizes binder jet printing and stereolithography principles, and capitalizes on their advantages to improve productivity. The proposed SEAM process was applied to stainless steel 420 (SS420) and the processing conditions (green part printing, debinding, and sintering) were optimized. Finally, an SS420 turbine fabricated using these conditions successfully reached a relative density of 99.7%. The SEAM process is not only suitable for a high-volume production environment but is also capable of fabricating components with excellent accuracy and resolution. Once fully developed, the process is well-suited to bridge the productivity gap between metal AM and TM processes, making it an attractive candidate for further development and future commercialization as a feasible solution to high-volume production AM.

This study developed a theoretical framework on the relationship between land marketization and industrial high-quality development (HQD) to guide the formulation of policies for advancing new industrialization and high-level manufacturing capabilities. An evaluation system was constructed that can assess regional industrial HQD in seven dimensions: innovation, efficiency, structural optimization, financial risk control, openness, social welfare, and greenness. Based on data related to urban primary land markets and different industries in Guangdong province, China, from 2007 to 2021, the effect of land marketization on industrial HQD was explored using the evaluation models of land marketization and industrial HQD, the Theil index, a panel data model, and the difference generalized method of moments. The findings revealed that land marketization and industrial HQD have increased gradually in Guangdong. In the Pearl River Delta (PRD), both factors have increased rapidly, albeit with low levels of land marketization and high levels of industrial HQD. Notably, the province-wide scores for financial risk control and openness have declined. In the PRD, scores for efficient and financial risk control have consistently been lower than those outside the PRD. Positive relationships were discovered between land marketization and various aspects of industrial HQD, including industrial innovation, efficiency, structural optimization, greenness, and social welfare. Conversely, land marketization was found to have negative relationships with financial risk control and openness. Compared with that in the non-PRD, land marketization in the PRD was more conducive to industrial HQD, innovation, efficiency, structural optimization, and openness but less conducive to greenness, social welfare, and financial risk control. This research concluded that land marketization can promote industrial HQD through rising land prices and an open and fair environment for land market trading. The results of this study enrich the theoretical knowledge of the effects of industrial HQD in China; thus, they can be used as a reference in the formulation of industrial HQD policies related to market-oriented reform and land allocation in China.

Empirical studies suggest that investing in consumer education on green consumption not only naturally induces environmental sustainability but also yields various economic benefits for the original equipment manufacturers (OEMs). However, as far as we know, these studies overlook the potential cannibalization of new product sales. By developing a theoretical model that involves consumer education on green consumption when choosing between in-house or outsourcing remanufacturing, we find that if allowing the flexibility of remanufacturing outsourcing, consumer education on green consumption introduces opportunities for opportunistic behaviors that can compromise both profitability and environmental objectives. Specifically, when OEMs engage in remanufacturing, either in-house or through outsourcing, we observe that the incentive to invest in consumer education on green consumption is greater for in-house remanufacturing compared to outsourcing. This heightened incentive for consumer education enables OEMs to maintain higher profits under remanufacturing in-house, which results in a threat to environmental sustainability. Full article
