Study on the composite fracture characteristics of filling and reinforcing cracked rock mass after high temperature damage

Deep Underground Science and Engineering, EarlyView.
Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

Coal and gas outburst prevention using new high water content cement slurry for injection into the coal seam

International Journal of Mining Science and Technology, 2017
As coal and gas outburst is one of the most serious mine disasters, it is very important to at least control it if not prevent it from occurring. Injecting cement slurry or grouting into the coal seam can strengthen the seam, increase its rigidity ...

ZnO‐Coated Silicon Oxide Nano‐Anode: Synergistic Enhancement of Cycling and Thermal Stability of Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Lithium‐ion battery anodes that maintain good performance and excellent stability under high temperature conditions. Silicon oxide (SiO) has great potential as a high‐capacity anode for lithium‐ion batteries, but its practical use is limited by excessive volume expansion (>200%) and rapid capacity fade, especially at high temperatures.

Study on stability of coal water slurry under different coal water slurry dispersants by using stability analyzer

IOP Conference Series: Materials Science and Engineering, 2019
Abstract The stability analysis of CWS by Turbiscan Lab stability analyzer not only can clearly observe the change of the supernatant layer in the slurry, but also can observe the change of the turbid area. It can objectively reflect the agglomeration and flocculation in the slurry, Settlement and a series of changes.
