“…As can be seen, the H/C ratio decreases in the respective proportion of the increase in the C content and the decrease in the H content, indicating that to reach an H/C ratio identical to that presented by Long et al (2013) for carbon black, which was 0.006, everything points to the need to change the parameters of the pyrolysis process, specifically by increasing the temperature or by increasing the residence time. This methodology follows on from the work by Hong et al [54], who resorted to the analysis of the ratio between H and C to differentiate carbon black from black carbon using a ternary plot based on elemental analysis, defining as the axes of the ternary plot the ratios H/C × 100-log(C/10)-1/H. With this procedure, the authors divided the triangle precisely at 50% of the lower axis, with the carbon black samples located on the left side of the diagram, and the black carbon samples located on the right side of the diagram.…”

The common use of tires is responsible for the production of large quantities of waste worldwide, which are landfilled or energetically recovered, with higher economical cost and known environmentally harmful consequences. This type of problem must be studied, and all efforts must be conducted to eliminate, or at least mitigate, such high costs. The use of thermochemical conversion processes, such as pyrolysis, can allow the recycling and the reuse of raw materials for the tire industry, namely, in the production of carbon black, usually produced using the controlled combustion of fossil fuels. This article reports the production of torrefied and carbonized waste tire samples using a laboratorial procedure, and their subsequent laboratory characterization, specifically the elemental and proximate analysis. This preliminary approach found that carbon concentration in the produced rubber char reached values higher than 75%, indicating the possibility of its reuse in the production of carbon black to in turn be used in the production of new tires or other industrial rubber materials. The possibility of using this rubber char for other uses, such as energy recovery, is still depending on further studies, namely, the evaluation of the amount of sulfur present in the final product.

“…Order to nd the differences of dominant Species among the three groups of samples at each classi cation level (Phylum, Class, Order, Family, Genus), the top 10 Species with average abundance at each classi cation level were selected to generate a Ternaryplot. In order to intuitively check the differences of dominant species among the three groups of samples at different classi cation levels (Hong et al, 2021).

Purpose: As a newly cultivated grass species widely used in saline-alkali soil treatment, Juncao"Oasis No.1" can effectively enhance the microbial population abundance in saline-alkali soil. It has a good effect on improving saline-alkali soil.Methods: In order to further study the microbial community in the rhizosphere soil of Juncao"Oasis No.1" , the dominant strains with important ecological value were screened out. In this paper, soil samples were collected from saline-alkali soil planted with Juncao"Oasis No. 1" and unplanted Juncao"Oasis No. 1", and the microbial populations were sequenced by 16SrDNA high-throughput sequencing, in order to identify the difference of microbial population, the dominant bacteria in rhizosphere soil of Juncao"Oasis No. 1" was selected, and the dominant bacteria with important ecological value were isolated and cultured and identified by Colony PCR.Results: The results showed that Pseudomonas fluorescens and Bacillus thuringiensis. were the dominant strains with important ecological value in rhizosphere soil of Juncao"Oasis No.1" . After isolation and culture, Colony PCR identification showed that the dominant strain was successfully isolated and cultured.Conclusions: In this paper, the dominant strains with important ecological value in rhizosphere soil of Juncao" Oasis No. 1" were screened and cultured, which provided theoretical basis for the improvement of saline-alkali soil by using Juncao"Oasis No. 1", it is of great guiding significance.

MicroRNA (miRNA) is an important tumor marker in the human body, and its early detection has a great influence on the survival rate of patients. Although there are many detection methods for miRNA at present such as northern blotting, real‐time quantitative polymerase chain reaction, microarrays, and others, electrochemical biosensors have the advantages of low detection cost, small instrument size, simple operation, non‐invasive detection and low consumption of reagents and solvents, and thus they play an important role in the early detection of cancer. In addition, with the development of nanotechnology, nano‐biosensors show great potential. The application of various nanomaterials in the development of electrochemical biosensor has greatly improved the detection sensitivity of electrochemical biosensor. Among them, carbon nanomaterials which have unique electrical, optical, physical and chemical properties have attracted increasing attention. In particular, they have a large surface area, good biocompatibility and conductivity. Therefore, carbon nanomaterials combined with electrochemical methods can be used to detect miRNA quickly, easily and sensitively. In this review, we systematically review recent applications of different carbon nanomaterials (carbon nanotubes, graphene and its derivatives, graphitic carbon nitride, carbon dots, graphene quantum dots and other carbon nanomaterials) for miRNA electrochemical detection. In addition, we demonstrate the future prospects of electrochemical biosensors modified by carbon nanomaterials for the detection of miRNAs, and some suggestions for their development in the near future.
