“…The generation of new energy is essential to the accomplishment of sustainable development since it is intertwined with social, economic, and environmental progress. Participation from members of the general population is required for the discovery of new energy sources [ 8 , 9 ]. Understanding the competitiveness of the NEI in Jilin Province is essential for determining the limiting factors, optimizing the regional energy consumption structure and industrial structure, and increasing the overall competitiveness of the regional economy.…”

This paper develops a regional new energy industry (NEI) competitiveness evaluation index system based on the theoretical framework of the “diamond model” and the unique characteristics of the new energy industry and made an empirical analysis of Jilin province with analytic hierarchy process (AHP) and fuzzy comprehensive evaluation method. The analysis results show that the new energy industry in Jilin Province has a good foundation, and the government’s role, talent support, technological innovation, and market factors are acceptable. However, due to location factors and resource endowments, regional GDP and per capita consumption expenditure are low. The lack of intrinsic motivation of industrial competitive advantage has resulted in the poor overall competitiveness of the new energy industry in Jilin Province. Then, it is advised to take targeted measures to work closely with national NEI development strategy, optimize the industrial technology innovation ability and the talent support, actively guide social capital flows and new energy consumption, optimize regional energy consumption structure and industrial structure by creating a complete NEI chain, and revitalize the whole economy.

“…Not only that but some existing research also adds CNMs to the soil as a soil amendment to improve soil nutrient cycling processes and crop growth. Gonzalez Alejandre et al (2021) have shown that CNMs can improve crop resistance to adverse effects, enhance crop yield, and improve the seed germination rate. Y. Li, Liu, et al (2022) demonstrated that multi‐walled carbon nanotubes (MWCNTs) could enhance the salt tolerance of grape seeds and seedlings, significantly increase the crop root length and seed germination rate, and maintain the antioxidant capacity of grape seedlings under high salt stress.…”

Carbon nanomaterials (CNMs) are extensively employed in diverse fields and will inevitably be discharged into the soil to affect the soil microbial community. Numerous related studies have investigated the effects of exposure to CNMs on soil microbial communities, yet a consensus on their effects still needs to be discovered. This study conducted a global meta‐analysis by synthesizing 474 pairs of experiments from 20 screened publications in the literature from 2000 to 2022. The findings indicate that: exposure to CNMs significantly reduced microbial biomass carbon (MBC) by 17.02% and increased soil Shannon index by 2.63% (p < 0.05), which had no significant effect on soil microbial community composition and only reduced the proportion of Proteobacteria by 6.83%. The type of CNMs was one of the important influencing factors. The exposure to multi‐walled carbon nanotubes (MWCNTs) significantly reduced the soil MBC (p < 0.05). It reduced the proportion of Acidobacteria, Bacteroidetes, and Proteobacteria in soil, which had less effect on soil microbial diversity and was more suitable as a crop growth promoter. The exposure of single‐walled carbon nanotubes exhibited a comparable impact on soil microbial biomass as MWCNTs while significantly increasing soil microbial diversity. The exposure of fullerene (C60) had no significant effect on soil microbial biomass but significantly decreased microbial diversity (p < 0.05). In addition, soil pH, CNMs exposure dose, and exposure time significantly affect the effects of CNMs (p < 0.05). This research recommends that CNMs be used in high pH soil with high electrical charge intensity while avoiding exposure doses exceeding 1000 mg/kg and limiting exposure time to 50–100 days to minimize long‐term exposure effects on the soil. MWCNTs are less toxic to microbial communities compared with the other CNMs and are more suitable as crop growth promoters. In conclusion, CNMs show great potential for promoting agricultural production.

Synthesis and characterization of Ag-ZnO nano-composites for investigation of variations in the germination of peanut and kidney beans

et al. 2021

In this study, the effects of Ag-ZnO nano-composites (NCs) on the germination of peanut (Arachis hypogaea) and kidney beans (Phaseolus vulgaris) have been investigated. Two synthesis techniques have been utilized including green Synthesis and sol-gel method to compare their effect on germination of both types of beans. Various inquring approaches including XRD, Scanning Electron Microscopy (SEM), EDX and UV-vis spectroscopy were employed to characterize the synthesized Ag-ZnO NCs. The XRD pattern showed that the synthesized powdered Ag-ZnO nano-composites have a highly crystalline pure structure without any secondary phase. SEM disclosed the spherical-shaped Ag NPs and rod-like ZnO NPs for green and sol-gel synthesis, respectively. The EDX spectra confirmed the materials through respective peaks of Ag, Zn and O which validates the synthesis of Ag-ZnO NCs. The different concentrations of nanostructures (100 ppm, 500 ppm and 1000 ppm) have been applied on peanut and kidney beans to study the variation in germination rate. The germinability, germination rate percentage, mean germination time (MGT) and root and shoot lengths are employed for consideration of variations in germination rate. In contrast to 1000 ppm concentration, both types of seeds present potential results at 500 ppm for green synthesis as well as sol-gel synthesis approach. This research is highly suitable for researchers for choice of suitable synthesis method as well as for food industry for the improvements in germination rates.
