“…Table 1 presents the fundamental characteristics of YA-U and YA-M. YA-U represents a meager coal with a R o,max of 1.87%, whereas YA-M exhibits an increased R o,max of 2.34%, indicating that it has reached the anthracite stage. This significant rise in the metamorphic grade of Yi'an mylonitic coal is attributed to geological tectonic stress, 39 which is consistent with the results of the dynamic metamorphic theory. 14 Additionally, these results lay a preliminary foundation for the potential graphitization of YA-M.…”

The flattening of nanoscale pores is a crucial step in the process of anthracite graphitization, which primarily occurs due to lithostatic pressure or tectonic stress. Anthracite, a highly metamorphosed form of carbonaceous material, is a primary component of artificial graphite, but its availability is limited in China. Therefore, it is necessary to investigate the graphitization of low metamorphic coal. Note that the pores of deformed coal are substantially compressed, and the evolution of macromolecular structure is accelerated owing to strong tectonic extrusion and shearing action. Herein, the feasibility analysis of coal-based graphite at temperatures of 2200 and 2600 °C was investigated using mylonitized meager coal (YA-M; R o,max = 2.34%), which exhibits the most intense deformation intensity, and it was compared with undeformed coal (YA-U; R o,max = 1.87%) from the same coal seam. Results indicate that YA-U primarily consists of cylindrical pores with an average pore diameter of 10 nm, while YA-M exhibits extensive fine bottleneck and parallel plate pores with an average pore size of ∼4 nm. Additionally, interlayer spacing decreases from 0.3592 nm in YA-U to 0.3575 nm in YA-M, while crystallite height increases from 1.9633 nm in YA-U to 2.1424 nm in YA-M. The undeformed coal YA-U exhibits short and disordered aromatic fringes with a localized turbostratic structure that hinders graphitization. In contrast, YA-M exhibits more and longer localized fringe pairs arranged in parallel with improved structural ordering, indicating a favorable environment for graphitization. Ductile deformation narrows the pore diameter distribution, causing deformation pores on the mylonitic granules' surface to close, shrink directionally, collapse, or connect, resulting in obvious flattening characteristics of nanoscale. Based on these results, the graphitization degree of the graphitized products YA-GM-2200 and YA-GM-2600 was 80.23% and 88.37%, respectively, with interlayer spacings of 0.3371 and 0.3364 nm, indicating that these products have entered the semigraphite (medium graphitization) and graphite range, respectively. In contrast, the graphitization degree of YA-GU-2200 and YA-GU-2600 was only 51.16% and 56.98%, respectively, indicating that they have only progressed from anthracite to meta-anthracite (the preliminary graphitization stage). These findings confirm the view that the shear stress generated by the geological age flattens the pores of mylonitized meager coal and optimizes the aromatic lattice arrangement and orientation, facilitating graphitization and lowering the graphitization temperature (from 2800 to 2200 °C). Deformed coal is soft and can be easily crushed into powdered form using the human hand, making it less suitable for transportation. Additionally, owing to the unfavorable separation of minerals and lower hydrocarbon-generating potential, deformed coal application potential and price are consistently lower than those of undeformed coal. However, deformed coal is widely distributed in various coal ...

Considering the growing emphasis on safety issues in mainland China, it is essential to identify the hurdles in the development of safety disciplines and to promote alignment between safety disciplines and society. To understand the current state of safety science and engineering disciplines in mainland China, we conducted a study while considering the geographical distribution level, as well as the power gap between universities. In terms of the geographical distribution, the spatial distribution characteristics of institutions with safety engineering enrollment in China were mapped out. To illustrate the development characteristics and existing safety discipline problems, the current situation of economic development and safety production in each region was integrated. In terms of power gaps, the Cingta database was used to study the disparity between different indicators and the competitiveness of safety disciplines in representative universities. Based on these findings, the development of chemical safety education is further discussed. Finally, development directions were provided for the effective reform of safety disciplines in each university at this stage. The study demonstrated that the current development status of safety disciplines in universities was related to social needs and social background. The development of safety disciplines in certain provinces of China did not match the current state of the local economy and safety products. There was a significant gap between the strengths and weaknesses of disciplines between universities and colleges.

“…Figure 1 illustrates input manufacturing resources and outcomes of typical production setup, and the place of manufacturing interoperations where the invisible layer of integrated elements needs to be monitored. Since environmental changes and shortages of natural resources became alarming [8], the relationship between the complexity of interoperating elements and unsustainable manufacturing procedures needs to be analyzed and, engineering sustainability becomes highly needed to be involved in curriculum engineering courses [9]. Understanding the technologies and hands-on practice become critical for a successful career in manufacturing engineering.…”
