Exploring the Relationship Between Productive Engagement and Well-Being: A Scoping Review

ABSTRACT As the global population ages, older adults become vital contributors to societal and economic development through various productive activities. This scoping review aims to synthesize qualitative and quantitative evidence for persons 50 years of age and older to address two fundamental questions: (1) What are the most common types of productive engagement activities chosen by older adults? (2) How does participation in these activities relate to the physical, cognitive, social, or emotional well-being of older adults? Following the JBI Manual for Evidence Synthesis (2020) and PRISMA-ScR Checklist, three databases were systematically searched using terms related to older adults and productive engagement. Inclusion criteria targeted studies focusing on productive engagement in older adults aged 50 and above, with no design restrictions, from 2000 to 2023. Nineteen articles met the inclusion criteria. Results revealed a range of productive activities, including paid work, volunteering, caregiving, and lifelong learning. Volunteerism emerged as a prevalent theme, enhancing older adults’ well-being. Caregiving, however, was associated with negative impacts on emotional well-being in some studies. The gaps identified included limited research on education-related activities and a reliance on secondary data sources. This review contributes to understanding productive engagement in later life and older adults´ role in society.

Ecological restoration in valley area of semiarid region damaged by shallow buried coal seam mining

Abstract Coal seams in valley areas are shallow buried, and mining activities have a strong impact on the surface environment, so ecological restoration in this condition is very difficult. Strengthening the monitoring of ecological changes plays an important role in optimizing mining methods and ecological restoration. In this article, a valley area in the northern Shaanxi Province of China was selected as the research area, and a similar ecosystem around the study area was selected as the reference subject. The traditional remote sensing ecological index model was improved, and a new evaluation model was constructed based on the framework of Modified Remote Sensing Ecology index-Deviation from Reference Ecosystem Index-Ecological Restoration Quality Index (ERQI) to study the evolution of the environment in the study area from the perspective of the whole life cycle of mining activities. The results showed that ERQI values in the study area experienced an evolution process from high to low and then gradually increased, reflecting the impact of coal mine production and restoration activities on the environment, in which Burn Area Index and normalized difference vegetation index were more sensitive; after nearly 10 years of restoration, ERQI values in the study area still had a large gap with that of the reference area, some suggestions for improvement of ecological restoration were put forward. The research provided a quantitative approach to describe the evolution of the ecological environment and a scientific basis for the ecological restoration in the mining areas.

Circular Economy in the European Union: A Prisma-Based Systematic Review and Meta-Synthesis

The most significant impact of the industrial production process is the environmental damage caused by the waste generated during production. European Union countries aim to reduce environmental harm by reintegrating waste, production inputs, and materials generated during production and consumption activities back into the production process. The purpose of this study is to evaluate the studies related to the circular economy in the context of European Union countries within the circular economy literature. For this evaluation, the authors used the studies from the circular economy literature available in the SCOPUS database for the period between 2004 and 2024. The analysis of the obtained dataset was conducted using the PRISMA (2015) approach. According to the findings, although many studies exist, most focus on implementing circular economy regulations and laws. Upon reviewing these publications, many were found unrelated to the circular economy. Furthermore, there is a significant gap in studies employing econometric models to analyze the circular economy, and no research has been found that performs a literature review using meta-synthesis methods specifically on the circular economy within the context of EU countries. These findings aim to fill this gap and guide academics and policymakers researching the topic.

Peroxisome proliferator-activated receptor alpha is an essential factor in enhanced macrophage immune function induced by angiotensin-converting enzyme.

Increased expression of angiotensin-converting enzyme (ACE) by myeloid lineage cells strongly increases the immune activity of these cells, as observed in ACE10/10 mice, which exhibit a marked increase in antitumor and antibactericidal immunity. We report that peroxisome proliferator-activated receptor alpha (PPARα), a transcription factor that regulates genes critical for lipid metabolism, is a key molecule in the enhanced macrophage function induced by ACE. Here, we used a Cre-LoxP approach with LysM-Cre to create a modified ACE10/10 mouse line in which macrophages continue to generate abundant ACE but in which monocyte and macrophage PPARα expression is selectively suppressed. These mice, termed A10-PPARα-Cre, have significantly increased growth of B16-F10 tumors compared with ACE10/10 mice with Cre expression. PPARα depletion impaired cytokine production and antigen-presenting activity in ACE-expressing macrophages, resulting in reduced tumor antigen-specific CD8+ T-cell generation. Additionally, the elevated bactericidal resistance typical of ACE10/10 mice was significantly reduced in A10-PPARα-Cre mice, such that these mice resembled WT mice in their resistance to methicillin-resistant Staphylococcus aureus (MRSA) infection. THP-1 cells expressing increased ACE (termed THP-1-ACE) constitute a human macrophage model with increased PPARα that shows enhanced cytotoxicity against tumor cells and better phagocytosis and killing of MRSA. RNA silencing of PPARα in THP-1-ACE cells reduced both tumor cell death and bacterial phagocytosis and clearance. In contrast, the in vivo administration of pemafibrate, a specific agonist of PPARα, to WT and A10-PPARα-Cre mice reduced B16-F10 tumor growth by 24.5% and 25.8%, respectively, but pemafibrate reduced tumors by 57.8% in ACE10/10 mice. With pemafibrate, the number of antitumor CD8+ T cells was significantly lower in A10-PPARα-Cre mice than in ACE10/10 mice. We conclude that PPARα is important in the immune system of myeloid cells, including wild-type cells, and that its increased expression by ACE-expressing macrophages in ACE10/10 mice is indispensable for ACE-dependent functional upregulation of macrophages in both mice and human cells.

The Effect of Financial Deepening and Borrowing Cost on Aggregate Output in Nigeria and its Policy Implications

This study examines the effect of financial deepening and borrowing costs on aggregate output using secondary data from 1986 to 2022. The effect of financial deepening and borrowing costs on aggregate output is expressed in an autoregressive distributed lag (ARDL) model. The findings of the study indicate that the state of financial deepening in Nigeria is not sufficient to drive production to optimal levels, indicating that there are unrealized gains in the business of providing financial intermediation services in the economy. The result of the estimated models shows among other things that aggregate output is inelastic to changes in lending rate, indicating that raising policy interest rate will lead to minimal losses in output. It also shows that financial deepening has the potential to contribute significantly to output growth. It is concluded that financial deepening in the short run may not be achieved by relying totally on market equilibrium where it is expected that the market for credit and other financial services will clear and produce optimal macroeconomic outcomes. Rather, policies (reforms) should be made to heighten the demand and supply of credit in the economy to support real sector production activities.

Co Nanoparticles on MnO: Electron Transfer through Ohmic and S-Scheme Heterojunction for Photocatalytic Hydrogen Evolution.

The photocatalytic hydrolysis method represents a significant potential solution to the dual challenges of energy security and environmental sustainability. The selection of suitable photocatalytic materials and systems is of paramount importance for the successful implementation of photocatalytic hydrogen production technology. In this study, in situ reduction of Co nanoparticles on MnO was successfully performed by calcining MnCo-PBA. Furthermore, graphdiyne (GDY) was successfully introduced by physical agitation. The introduction of GDY reduced Co/MnO agglomeration and made the Co/MnO/GDY catalyst exhibit high activity in hydrogen production, with an optimum production rate of 2117.33 μmol·g-1·h-1, which was 4.88 and 2.67 times higher than that of GDY and Co/MnO, respectively. The results of the photoelectrochemical test indicate that the composite catalyst has a better photogenerated carrier separation efficiency. In situ X-ray photoelectron spectroscopy, density functional theory calculations, and electron paramagnetic resonance were used to investigate the electron transfer mechanism during the photocatalytic process, confirming the presence of an S-scheme heterojunction and an ohmic junction, which enhance the separation of photogenerated carriers. The GDY-based heterojunction catalyst constructed in this study has the potential to significantly enhance the hydrogen production activity of bimetallic catalysts.

Assessment of metabolic syndrome in railway workers

Metabolic syndrome is currently the leading cause of the development of cardiovascular pathology.This is associated with an increase in the prevalence of overweight and obesity, which leads to a significant increase in related metabolic diseases. The production activities of workers in many railway professions, primarily locomotive crew workers, are characterized by high psychoemotional stress, which is an important risk factor for the development of metabolic syndrome. Objective: to establish an association between the prevalence of metabolic syndrome Materials and methods: 220 men have been included into the research, workers of railway transportation with arterial hypertension. All the men have been divided into two groups according to their profession. The first group consisted of 114 workers of locomotive brigades (engine drivers and their Assistants). 106 workers of a railway transportation of other specialties have been included in II group. General clinical part of the study included: collection of complaints, medical history, work experience and duration of the disease, examination, anthropometric data with determination of body mass index, waist circumference. Laboratory tests included assessment of biochemical parameters (total cholesterol (TC), high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), triglycerides (TG), glucose, fasting blood sugar and 2 hours after meals). Results: The frequency of metabolic syndrome is 37% and 35%, respectively, in the first and second groups. Significant differences were found in the prevalence of abdominal obesity: among workers of locomotive crews, abdominal obesity was significantly more common by 14% than among engineers (office workers) (χ² = 8.42; p = 0.004). Among men of working age, workers in stressful professions (machinists and their Assistants) more often have a combination of three components of MS: hypertension with AO and an increase in the concentration of LDL-C >3 mmol/l. The following clusters of metabolic syndrome are more often observed in office workers (engineers): hypertension with AO and hypertriglyceridemia and hypertension with AO and hyperglycemia. Conclusions: The received results specify in necessity of carrying out of primary preventive maintenance arterial hypertension among workers of locomotive brigades.

Technical Education in Bolivia 1825–1900: Ideas, Achievements and Obstacles to Development

ABSTRACT This paper argues that the failure to implement state technical education in Bolivia was one of the reasons for the country’s economic backwardness. The work makes a key contribution to the history of Bolivian education as it studies aspects not dealt with in the literature so far. First, it details the chronology of the development of technical education in Bolivia and analyses the types of education offered by the State. Second, it looks at the scope of the technical education that was available and whether this adapted to the need for specialised labour that the country’s production activities – which were still pre-industrial – may have had in the nineteenth century. Primary archival sources and periodical publications of the time have been used for this analysis.

Metformin Induces Apoptosis and Ferroptosis of Ovarian Cancer Cells Under Energy Stress Conditions

As ovarian cancer progresses, increased glucose use causes a glucose shortage in the tumor microenvironment. Therefore, it is crucial to find drugs that can effectively kill cancer cells in this energy stress setting. Here, we propose an effective therapeutic strategy that combines nutrient restriction with metformin to combat tumors. This study investigated the effects of metformin on ovarian cancer cells under energy stress conditions, mimicking the nutrient-deprived tumor microenvironment. We revealed that Metformin (10 mM) significantly reduced cell viability and proliferation under glucose deprivation conditions. Furthermore, it enhanced apoptosis and ferroptosis, as demonstrated by alterations in apoptotic protein expression and elevated levels of lipid reactive oxygen species (ROS), malondialdehyde (MDA), lipid peroxidation (LPO), and Fe2+. Transcriptional profiling revealed significant alterations in genes related to iron homeostasis and oxidative phosphorylation. Moreover, Metformin was found to induce mitochondrial dysfunction without affecting mitochondrial DNA or the expression of enzymes in the tricarboxylic acid (TCA) cycle, resulting in decreased ATP production and compromised activities of the respiratory chain complexes. The direct interaction between metformin and the NDUFB4 subunit in mitochondrial complex I was corroborated through the application of cellular thermal shift assay (CETSA) and drug affinity responsive target stability (DARTS) assays. In vivo, the combination of metformin and fasting cycles significantly inhibited SKOV3 cell-derived xenograft tumors in immunodeficient mice. Altogether, we have demonstrated that Metformin potentiates apoptosis and ferroptosis in ovarian cancer cells under energy stress conditions by targeting the NDUFB4 subunit of mitochondrial complex I, thus laying the groundwork for clinical testing. This study, though limited to cellular and animal levels, provides valuable insights into the therapeutic potential of metformin in ovarian cancer treatment.

Capturing changes in social functioning and positive affect using ecological momentary assessment during a 12-month trial of xanomeline and trospium chloride in schizophrenia.

Experiential negative symptoms (NS) are determinants of disability in schizophrenia (SCZ). Xanomeline/Trospium Chloride (X/T), an M1/M4 muscarinic receptor agonist, is an approved monotherapy for treatment of schizophrenia, including NS. We used remote ecological momentary assessments (EMA) to track changes in indicators of NS during 12months of outpatient treatment with X/T. After discontinuing previous medications, 566 outpatients with SCZ received open-label X/T monotherapy for up to 12months. Participants completed 3 EMA surveys 7days a week, one week a month. Surveys queried whether participants were home vs. away and alone vs with someone, as well as productive and unproductive activities, and moods. Hierarchical linear modeling (HLM) examined temporal changes and the relationships between the indicators of NS. 500 participants answered one or more EMA surveys and 350 met 33% adherence criteria, answering a total of 40,464 surveys, with overall adherence among these participants at 66%. During treatment with X/T, there were significant decreases in surveys at home (p<.001), alone (p<.001), and engaging in unproductive activities (p<.001). There were significant increases in productive activities both home (p<.001) and away (p<.001) and in positive affect (PA) (p<.001). Improvements in PA converged with reduced unproductive activities, particularly when others were present (p<.001). Behavioral indicators of NS improved early and were sustained with X/T treatment. Improvements were multidimensional, shifting toward more time with others, away from home, and engaged in productive activities. These improvements were associated with increases in PA, consistent with previous EMA studies of NS.

Pr doping promotes the formation of Pt single atoms by regulating metal-support interaction for remarkable photocatalytic hydrogen production

Since the metal-support interaction (MSI) has a great influence on the structure and properties of single atom catalysts (SACs), the activity and stability of SACs can be effectively regulated by adjusting the structure of the matrix. Herein, the morphology of surface supported Pt species can be controlled by doping to adjust the properties of TiO2 support. Specifically, under the same conditions, the Pt species on the Pr doped TiO2 surface are Pt SAs (PtSA/TiO2(Pr)), while on the pure TiO2 surface are particles (PtNP/TiO2). Experimental and theoretical studies demonstrate that Pr doping weakens the interaction of Ti-O bond, stabilizes the O-Pt unit site and Pt SAs. Impressively, PtSA/TiO2(Pr) shows superior photocatalytic hydrogen production performance (196.43 mmol g-1h−1), far exceeding PtNP/TiO2 (91.96 mmol g-1h−1). Additionally, Pr dopant modulates the electronic interaction between TiO2 support and Pt SAs, thus the adsorption/desorption behavior of H intermediates (H*) is balanced. Besides, the electron delocalization of O adjacent to Pt SAs can be adjusted by Pr doping, prompting the establishment of efficient Pt-O electron transfer channels and further enhances the utilization of photogenerated carriers. This study presents a promising strategy to prepare SACs with high activity for photocatalyst hydrogen production.

Enhancing meteorological data reliability: An explainable deep learning method for anomaly detection.

Accurate meteorological observation data is of great importance to human production activities. Meteorological observation systems have been advancing toward automation, intelligence, and informatization. Yet, instrumental malfunctions and unstable sensor node resources could cause significant deviations of data from the actual characteristics it should reflect. To achieve greater data accuracy, early detections of data anomalies, continuous collections and timely transmissions of data are essential. While obvious anomalies can be readily identified, the detection of systematic and gradually emerging anomalies requires further analyses. This study develops an interpretable deep learning method based on an autoencoder (AE), SHapley Additive exPlanations (SHAP) and Bayesian optimization (BO), in order to facilitate prompt and accurate anomaly detections of meteorological observational data. The proposed method can be unfolded into four parts. Firstly, the AE performs anomaly detections based on multidimensional meteorological datasets by marking the data that shows significant reconstruction errors. Secondly, the model evaluates the importance of each meteorological element of the flagged data via SHapley Additive exPlanation (SHAP). Thirdly, a K-sigma based threshold automatic delineation method is employed to obtain reasonable anomaly thresholds that are subject to the data characteristics of different observation sites. Finally, the BO algorithm is adopted to fine-tune difficult hyperparameters, enhancing the model's structure and thus the accuracy of anomaly detection. The practical implication of the proposed model is to inform agricultural production, climate observation, and disaster prevention.

Firm ownerships matter in measuring carbon footprints and its driving forces in China's domestic value chains.

Some research has studied the carbon footprints of the multinational enterprises (MNEs) in the global value chains (GVCs). However, currently there are few studies have studied the carbon footprints of the foreign invested firms (FIFs) distributed in different provinces in China's domestic value chains (DVCs). This paper has used China's inter-provincial input-output table distinguishing domestically owned enterprises (DEs), Hong Kong, Macao, and Taiwan (HMTs) invested enterprises and other foreign invested enterprises (FIEs) to study the carbon footprints of the FIFs in China's DVCs and further analyzed the driving factors of the carbon footprints change. The results show that: (1) In 2017, more than two-thirds of the carbon footprints came from FIEs and this proportion had decreased 5.6% compared with 2012. The FIFs located in coastal provinces or economically developed areas basically have the largest carbon footprints. (2) The production activity of the FIFs located in some developed provinces has mostly driven the carbon emissions of other provinces that have direct or indirect trade with them. While in some less affluent energy provinces, it has mainly driven the carbon emissions of the local DEs. (3) The biggest driving factor for reducing the carbon footprints of the FIFs is the carbon emissions intensity of the DEs, followed by the input-output relationship between DEs and FIFs. The final product production of the HMTs is the largest driving factor that promoting the increase of the FIFs' carbon footprints, followed by the final product production of the FIEs. However, different driving factors have different contributions in different provinces. The research results of this article have important research significance for reasonably introducing foreign investment and promoting the reduction of the FIFs' carbon footprints in various provinces in China.

H2 production from the photocatalytic reforming of ethylene glycol: Effect of TiO2 crystalline phase on photo-oxidation mechanism

In this work, the mechanism of H2 production from ethylene glycol as a model compound for photoreforming over platinized TiO2 is presented with particular focus on the effect of the TiO2 polymorph. It was found that Pt/anatase and Pt/anatase:rutile (P25) had similar H2 production activities and both catalysts followed an indirect oxidation pathway where ethylene glycol was oxidised via hydroxyl radicals to glycolaldehyde. In contrast, Pt/rutile primarily oxidised ethylene glycol directly into formaldehyde. The formaldehyde was unable to react further, which significantly reduced the formation of hydrogen despite similar conversion of ethylene glycol compared with the other supports used. We propose that these differences are due to different adsorption behaviour and hole transfer mechanism on the different TiO2 crystalline phases. In particular, ethylene glycol complexation on Ti5c sites on the dominant (110) facet of rutile leads to a direct hole transfer and an oxidative C–C cleavage mechanism prevailing.

Are visitors, biodiversity or timber production better for nature conservation? Findings from an econometric analysis of the management costs of protected areas in Serbia.

Protected areas (PAs) are designed to provide a wide range of ecosystem services (ES) and to conserve biodiversity, alongside cultural values. Understanding the production processes within PAs is crucial to decipher the relationships between different ES, including primary (timber) production and the provision of public goods, and to assess their degree of 'jointness'. This article models PA management as a joint production activity involving multiple outputs, including biodiversity, recreation, and timber production. Using panel data on management costs from 57 PAs in Serbia (representing 82% of the country's protected area), we estimate a variable cost function, that accounts for potential endogeneity due to unobserved PA-specific heterogeneity. Our results show that increasing species richness and extending strict protection zones leads to additional management costs, but with different elasticities. A 10% increase in species richness outside strict zones increases costs by 4.9%, while within strict zones the increase is 5.77%. Timber production shows diseconomies of scale, suggesting that large-scale timber operations should be limited. Marginal cost estimates show that managing one additional species costs €11.80, one additional visitor costs €0.41 and one additional cubic metre of timber costs €44.43. We find no evidence of jointness between timber production and recreation, but there is competition between timber production and biodiversity. Conversely, biodiversity and recreation show complementarity in terms of protection costs. These findings are consistent with the Serbian PA management approach, which uses a land-sparing principle by spatially separating activities. This zoning strategy facilitates coexistence, allowing biodiversity to support local tourism and benefit from recreational activities.

Transient pulsed discharge preparation of graphene aerogel supports asymmetric Cu cluster catalysts promote CO2 electroreduction

Designing asymmetrical structures is an effective strategy to optimize metallic catalysts for electrochemical carbon dioxide reduction reactions. Herein, we demonstrate a transient pulsed discharge method for instantaneously constructing graphene-aerogel supports asymmetric copper nanocluster catalysts. This process induces the convergence of copper atoms decomposed by copper chloride onto graphene originating from the intense current pulse and high temperature. The catalysts exhibit asymmetrical atomic and electronic structures due to lattice distortion and oxygen doping of copper clusters. In carbon dioxide reduction reaction, the selectivity and activity for ethanol production are enhanced by the asymmetric structure and abundance of active sites on catalysts, achieving a Faradaic efficiency of 75.3% for ethanol and 90.5% for multicarbon products at −1.1 V vs. reversible hydrogen electrode. Moreover, the strong interactions between copper nanoclusters and graphene-aerogel support confer notable long-term stability. We elucidate the key reaction intermediates and mechanisms on Cu4O-Cu/C2O1 moieties through in situ testing and density functional theory calculations. This study provides an innovative approach to balancing activity and stability in asymmetric-structure catalysts for energy conversion.

Pengaruh Organisasi Kemahasiswaan Terhadap Belajar Mahasiswa Difakultas Sains Dan Teknologi

Student activity in organizations plays an important role in developing knowledge and preparing them to enter the world of work. Through organizations, students are accustomed to conveying thoughts and ideas that can increase self-confidence and motivation to learn, which has a positive impact on academic achievement. This research aims to examine the role of student organizations in supporting student abilities, using descriptive methods. The research sample consisted of 10 students from the 2022/2023 information technology study program. The research results show that there is a significant influence between student involvement in student organizations on their learning achievement. Student organizations provide opportunities for students to develop their talents, interests and potential through productive, creative and practical activities carried out on campus, for example extracurricular activities, which in turn increase motivation and academic achievement. In addition, involvement in an organization can shape character, skills, self-confidence, as well as expand knowledge, insight and social networks. This research also reveals that students are involved in organizations not only for existence or popularity, but as a form of self-actualization. Therefore, it is recommended that the campus, such as the Deputy Chair III for Student Affairs and Study Programs, provide further support to encourage student organization activities that can improve student achievement. Overall, this research shows that involvement in student organizations has a significant positive relationship with learning motivation, which influences academic quality and preparation for the world of work.

Role of Mahatma Gandhi NREGA in Building Rural Infrastructure and Sustainable Development

This paper discusses the role of the Mahatma Gandhi National Rural Employment Guarantee Act in creating and strengthening various infrastructure assets in rural India. It critically analyses the number of assets, employment generation, and contribution to improving rural livelihoods. It also analyses the amount spent on each infrastructure activity, with a particular focus on agriculture, natural resource management, basic services-related works, and the construction of infrastructure to support the production activities of Self-Help Groups (SHGs). The information for the paper was obtained from the Ministry of Rural Development (MoRD) website. The analysis adopted is to work out the percentage of expenditures on various assets and the number of works carried out from 2013-14 to 2023-24. Based on the analysis, the paper has uncovered sufficient evidence of the growing trend of allocating funds to infrastructure strengthening, with over 60 per cent of Mahatma Gandhi NREGS funding allocated to assets related to agriculture and Natural Resource Management (NRM) activities. The last two years have seen an annual expenditure of around Rs. 30000 crore on building rural infrastructure, primarily in the agriculture sector, which has significantly strengthened rural livelihoods and reduced poverty. Finally, this paper provides policy suggestions to improve the governance for better implementation of the Mahatma Gandhi NREGA.

Synergizing Mg Single Atoms and Ru Nanoclusters for Boosting the Ammonia Borane Hydrolysis to Produce Hydrogen

Development of efficient catalysts with high H2O molecule activation ability holds great importance for H2 production. Herein, enzyme‐mimic Mg single atoms catalysts (SACs) coordinated by B/N‐doped carbon nanotube (BNC), was constructed as a high‐performance support for ruthenium (Ru) nano‐clusters. Dual functions of Mg SACs were discovered, where the Mg atoms beneath Ru catalysts built an interfacial electron polarization, inducing electron transfer from Ru to the Mg‐BNC support. In addition, the oxyphilic Mg SACs adjacent to the Ru catalysts could actively participate in H2O adsorption. The combination of experimental characterization, reaction kinetics study and density functional theory (DFT) calculations validated a stronger intrinsic H2O activation capability at the positive Ru sites. Meanwhile, the synergistic Mg SACs jointly contribute to the acceleration of the sluggish H2O dissociation process in ammonia borane (AB) hydrolysis reaction, resulting in exceptional hydrogen production activity and catalytic stability, outperforming most state‐of‐the‐art Ru‐based catalysts. This work provides a new strategy for utilizing alkaline earth metals as both the electronic promoter and the reactant activator, offering inspiration for the development of advanced heterogeneous catalysts.
