Herein, an innovative BiVO<sub>4</sub>/CoNiFe-LDH S-scheme heterojunction was strategically designed and constructed by tightly anchoring BiVO<sub>4</sub> microrods onto the surfaces of CoNiFe-LDH microflowers, and its degradation performance was assessed via eradicating tetracycline under visible light irradiation. Unsurprisingly, the optimal BiVO<sub>4</sub>/CoNiFe-LDH heterojunction acquired the maximum apparent rate constant of up to 0.0120 min<sup>−1</sup> for tetracycline removal, which was approximately 10.0 and 2.0 times more fast than those of sole CoNiFe-LDH (0.0012 min<sup>−1</sup>) and BiVO<sub>4</sub> (0.0061 min<sup>−1</sup>), separately. The significantly boosted photodegradation activity was benefited from the creation of S-scheme heterojunction at the interface between CoNiFe-LDH and BiVO<sub>4</sub>, considerably expediting the charge separation and maintaining the powerful redox capacity under the force of established internal electric field. Furthermore, reactive species substantiation tests corroborated that •O<sub>2</sub><sup>–</sup> and h<sup>+</sup> were greatly contributed to tetracycline degradation. In the end, the possible degradation pathways and mechanism of tetracycline were also elucidated.

In this study, a combination of numerical simulation and experimental is used to analyze the fatigue failure mechanism and fracture causes of the core tube blades of the slotted vortex finder cyclone separator. Through experimental observation and numerical simulation methods, the effects of different core tube blade structures on torque and separation efficiency are discussed in detail, aiming to improve their durability and separation performance. The findings indicate that an increase in the number of side seams can effectively reduce the torque exerted by the leaf. An increase in the number of side seams to 16 results in the highest level of particle separation efficiency. Furthermore, an increase in side seam height has a notable effect on the torque and separation efficiency of the blade. The optimal separation efficiency is achieved when the side seam height is 200 mm. Moreover, an increment in the angle of the side seam leads to an augmentation in both the torque and the separation efficiency of the blade.

After the aluminum dust layer is ignited by the transient ignition temperature, the local hot spots gradually spread until the dust combustion is completed. Due to the agglomeration effect of the smaller particle size aluminum dust, the transient ignition temperature of the aluminum dust layer decreases first and then increases with the increase of the particle size. As the power of the heating device increases, the ignition temperature of the aluminum dust layer gradually decreases. The flame propagation velocity of the tiled aluminum dust layer has a U-shaped relationship with the dust layer thickness and the dust particle size.

While numerous studies have shown that surfactants can effectively inhibit coal dust, a systematic explanation of their mechanism remains lacking.

It details the pros and cons of traditional processes like coal seam water injection, spray dust removal, and foam dust removal. Considering the structures, ion effects of different surfactants, and their complex impacts on the coal dust inhibition rate, the paper determines the adsorption forms of various surfactants on coal dust surfaces. Results show that the inhibition effect on coal dust follows the order: anionic > nonionic > amphoteric > cationic. Also, the alkyl chain structure, benzene ring structure, ethoxy group structure, benzene ring position, and bond types significantly influence the inhibition rate. Moreover, the combination of anionic and cationic surfactants may bring unexpected benefits, and anionic-nonionic surfactants can synergistically wet coal dust, while other mixtures are less likely to show stronger advantages. The paper further analyzes evaluation methods at different levels, proposes optimal application conditions, explains each method’s evaluation mechanism, and constructs an evaluation system model for coal dust wettability from multiple perspectives of “macro experiments + meso characterization + micro simulation + theoretical calculation”.
